A bargain box of saws!!

I had a few good wins at the local markets this morning. An English made Stanley No.5 for $30 in good condition, a nice old metal drill box (1/16 - 1/4" in 1/16th increments) for $1, a beautiful English made "Whitmore" 6" wood vice for $18 (I am always on the hunt for these vices - great for kids' benches), plus a few other goodies. However the bargain of the day was a plywood toolbox full of saws. Nine saws, in fact. The box and contents for the princely sum of $20. Even if only 3 of the saws were any good, it was still the bargain of the day.

The toolbox with the 3 saws worth using. Minus the other 6 more dodgy saws.
Of the 9 saws which came in the beaut tool box, 6 had plastic handles and were of very low quality. Scraper material if I'm lucky. However, the remaining 3 saws are worth putting back into service. Here's the specs of these 3 saws:
  1. Disston tenon saw, more modern type. 10 inch blade, 13 point. Good condition.
  2. Small panel saw. 13 3/4 inch blade, 10 point. Just needs cleaning up.
  3. Big rip saw. 26 inch blade, 5 point. It's had a hard life, but is restorable for use.
Help with identification and information, please!
I would really value input from any saw buffs out there who are reading this blog post.

The small panel saw.
This one is a mystery, but will be very useful to me. Small, the blade is only 13 3/4" long. It looks like a beech handle, but the medallion is interesting... it has the Disston symbol, but no wording on it. Well, not all the Disston symbol. The border only to the familiar "Scales" picture, the round circle of dots, but that's it...

The beech handle of the small panel saw. 

The small saw's Medallion has a version of the Disston symbol, but no text.

What's that interesting "tooth" on the back of the blade near the toe?
 OK, all you saw experts out there... maybe you can help me out. I would love to know more about this saw. Please feel free to post a comment with any info you can offer about this nice little saw.

The Big Rip Saw.
Yes, it's had a hard life, as evidenced by the handle. But the blade is in quite OK condition.

The big saw's original nuts are missing ... so is this the original handle?

The big saw's medallion. Interesting!
 "Warranted Superior" is a common name on many older saws. The thing I note about this one is the coat of arms, which includes a crown, a lion and what looks like a gazelle. It also has a latin inscription. Does the crown indicate that it is English made?

Once again, any information or suggestions about these two saws will be most appreciated. Please feel free to offer info via a Comment.

So why bother about the details on these saws?
These saws will be cleaned up, repaired where necessary, sharpened, and put back into service. So what's the big deal to me about the background on the saws? The most important thing is that they cut well. I am not a collector, but a user. The many people I teach woodworking hand skills to will be using these saws. It is the history which fascinates me, and I find lots of people are interested in the history of the saws they use with me.
I resist the terrible "throw away saw" mentality which seems to prevail in the timber trades today. These plastic handles things are made of inferior steel with hardpoint teeth which cannot be sharpened. Sure, they are cheap and they cut like champions while sharp - but are discarded into the skip bin when dull. Crazy, eh?
Instead I encourage the cleaning up and putting back into service good quality saws which have been made to last for generations. It's much better for the planet and better stewardship of the original craftsmanship which went into the design and production of these saws originally. 
Call me a tool nerd, but old tools are much more interesting than those shiny plastic handled things, which are better used as "burger flippers". Call me a weird tool nerd, but I also feel a sense of connectedness with the tradesmen who used the old saws before me. I'm part of a succession of people who have had the privilege of using these beautiful tools to craft wonderful things with timber. These saws have soul. Feel the vibe... 

I look forward to receiving any thoughts and input about these two saws.

Meanwhile, I'll be cleaning up that nice toolbox ready to put it back into use. I can't believe it came full of saws for the total of $20. Bargain! Yep, I'm still smiling...

Kids enjoying woodwork at the Mosman Park Eco-Fair.

It was a great day today. The Mosman Park Eco Fair was organised by the wonderful group of people from the Mosman Park community, including bods from St Lukes Anglican Parish in Mosman Park, and they all did a fantastic job too. There was a wide array of stalls, displays, speakers, and activities. I was there doing woodwork with kids all day. It was flat out all day!
Nice work!

Kids love using the brace and bit! 

Looks like a lidded box under construction.
 This activity was just pure creative play. There were no set projects. Just benches, hammers and nails, a few other tools, and a mountain of wood. All the timber was derived from factory waste, packaging, roofing off-cuts, etc - which would normally all have been heading into the waste stream. Better to recycle and redistribute it back out in to the community in hundreds of things the kids have created and taken home!

The "sawing station" in use - textbook technique, too! Well done, Kiddo.

Kids very quickly learn to use the vices.
 During the day we went through a huge pile of timber. I have a big box of wood there for the kids to rummage through, and I keep topping it up throughout the day. The wood is predominantly soft stuff, to make it easier for the kids to hammer nails into - bits of pine, plywood, dowelling, etc.

Here's a palacial residence under construction.

Some of these kids hung around for hours, making stuff.

Nice aeroplane.
 Parents derived a lot of pleasure from seeing their kids enthralled and engaged in their woodworking projects.  Kids derived lots of pleasure from using the tools and creating stuff which came into their heads. The pounding of 20 hammers went on all day.

My task was to wander amongst the seven benches, give advice on tool use and problem solving, offer encouragement and praise, and keep up the supply of timber, nails, and tools. Very busy all day. All around me were kids engaged in creative play, experiencing the joy of wood. That was, after all, the whole idea...

Thanks, St Luke's and other Mossie Parkers, for turning on this great day for the wider community.

External Stairs from Recycled Timber.

Aahh!... another set of stairs...   Amid all the different types of woodwork I do, what I enjoy about building stairs is the brain challenge they provide - particularly in the planning and setting out phase. One of my latest jobs has been to build a set of external stairs for a client. The task was to plan and build a set of stairs which would fit into a particular space on an existing building which was undergoing significant renovations. The stairs would comply with the Building Code of Australia, and made primarily from recycled jarrah.
That's the space available to build the stairs ... in front of the red brick wall.
View from the top looking down. The structure would have to keep 1.5m off the fence line.

Planning the job.
Having taken measurements on site, it was then down to the planning stage - which always involves doing scale drawings on my trusty drawing board. I have never got into CAD drawing on the computer. I still like the old "Technical Drawing" techniques using a T-Square and pencils on a drawing board.
The first place to start with planning a set of stairs is to know the total Rise - the distance from the top floor level to the bottom ground level. In this case, allowing for the new ground level which will be built up to the same height of the underside of the back door sill, the total rise will be 2.5m. This divides readily into 15 steps, each with a rise of 166.67 mm. That rise fits within ergonomic convention. The next thing to determine is the "Going" - the horizontal depth of each step from nosing to nosing. The accepted rule is: (2 x Rise) + Going = 585 (or up to 625mm.)   I decided to have a Going of 260mm, which fits within the range OK.
With the Total Rise, the number of steps, the Rise and Going all established, the length of the flights can be determined. Drawing this to scale would give me the angle of the stringers and help me to visualise how it will fit within the space. A landing will need to be included, as this divides and separates it into two flights going in opposite directions. There also had to be the required minimum standard headroom where the lower flight approached the ground while coming under the top balcony.
After a lot of drawing, calculating, brain-waves coming in the dead of night, meetings with the client and 3 drawing versions later, I believed we had hit on the answer of how to make it fit in the space available and my client was happy too.

Gathering the timber and starting the construction. 
The treads would be easy. Three sticks of timber dressed to 90 x 45 (and nearly 900 long), with gaps of 8mm between, would give a stair tread of  286. With a 260mm Going, there would be a 26mm overhang of the nosing over the back of the tread below. Nice. These sticks would be ex 4"x2" jarrah. In domestic buildings these were normally used for floor joists, rafters and often ceiling joists. Much of the 4"x2"s I had in my stocks came from a house built in 1930. After seasoning for 80 years, this stuff is dry!

4" x2" material cleaned up and ready to be machined to size.
  As much as possible, gum veins were avoided in the selection process, the timber docked just overlength, de-nailed, scanned with a metal detector, scrubbed down with a wire brush, straightened and squared over the buzzer, and machined to the required 90 x 45 through the thicknesser. Three of these per stair tread.

The stringers were a problem. After searching round the salvage yards, I would be unable to find the jarrah suitable to make the stringers. (Stringers have the treads housed into them and make up the sides of the stairs). So I had to buy the material new. The required 10" x 2" jarrah I purchased was pre-dressed and what they call prime grade. Scary stuff really, as I had to pay over $650 for the 4 sticks I would need in order to make the 2 pairs of stringers! Ouch!

The decking would be easy. By ripping 4"x2" jarrah sticks down the middle, the two halves are each machined to 90 x 20mm.  A number of these I was able to make at 3.2m long, enough to go the full length of the decking. The arrisses were shot off with a block plane, and the decking boards pre-coated with oil.

A 4"x2" piece of jarrah ripped down the middle and opened out. Fantastic colours and interesting nail holes coming in from the edges. It will be machined into beautiful recycled jarrah decking. 
  The top plate or apron of the landing would be ex 8"x2" jarrah, dressed to about 45 x 190mm, and the landing floor joists were ex 6"x2" jarrah from salvage. The landing would be supported by 6 galvanised steel legs set in concrete, and the jarrah posts above would be machined to 100x100mm. These took a lot of hunting down - from salvage yards and other sources. I was fortunate to get 4 posts from an old 6"x6" jarrah power pole! The 120 x45mm handrails would also be obtained from the 6"x2"s.
All nails and other fixings used would be Hot Dipped Galvanised. The finish to be applied to the finished timber would be Cabot's Natural Decking Oil.

The construction process started with making a set-out board of the stringers, giving me the angles and dimensions of the tricky ends of the stringers. This info was then transfered on to the stringer material and the two pairs of stringers were then made at my workshop and pre-finished with a couple of coats of oil.
The Stringers were laid out in pairs, marked out, and the tread housings cut.
The treads were then all made and cut to size ready. The two flights would be too heavy to lift if assembled, so I decided to do the assembly on site. With the flight components made and the landing materials organised, I moved to the site to build the landing. When the setting out on site was completed, the holes were dug for the steel posts. Using lots of big cramps and big sticks of timber, all the prepared posts were suspended in their holes, plumbed and held in the right positions. My son Ben was giving me a hand that day, and it was a big day! Ben operated the electric cement mixer and we did the concreting job. Six posts, rock solid. The following day I would do the concreting of the final two, supporting the base of the lower flight.

One of the steel posts suspended and cramped in position in its hole, awaiting the concrete.

The top stringers were also suspended/supported  in place to ensure the landing position was correct. While working from the drawings, sometimes it is good to check "in the flesh". 

The lower flight stringers fixed in place, with metal spiggots at the base set in concrete. The concrete will later all be buried under sand and brick paving.
 Completing the landing.
With the steel posts set in concrete and the landing apron or top plate being bolted to the steel as the jarrah posts were inserted into them, the floor joists were then added. These in place, the decking was then nailed down.

Decking nailed down and completed. That's a cake of soap on the stair tread - to lubricate the 4" galvanised nails used in landing construction.

Top flight treads fitted in place. Handrails and balustrading still to be added.

Landing done. Stringers in place, most treads installed. Time to cut posts to height and add balustrading. 
The jarrah posts were installed "over-long", so that they could be cut to a finish height after the transitions had been worked out - ie. where the flight handrails meet the landing handrails at the newel posts. These transitions would be calculated and modified ensuring a smooth transition as well as compliance with the minimum requirements under the Building Code of Australia (except for the lack of infill under the balastrading, which someone else would be doing.) While the scale drawings would give a good indication, the measuring and marking of the real thing in place would be most accurate. 

Making and Fitting the Handrails.
With the landing decking completed, it was time to get on with the handrails. The customer hadn't quite decided what balustrading to have - but will probably have stainless steel horizontal wires. That's someone else's job. Other than the posts below, I don't do steel. Out of interest, to comply with the BCA, balustrading must not be able to have a 125mm (5") sphere pass through any part of it. Horizontal handraisl must be a minimum of 1000mm high, etc. At the commencement of the job we had agreed I would only to install the newel posts and handrails, so that was what I was doing. I had made the handrails from ex 6"x2" jarrah ceiling joists. Nice straight sticks too, which I had machined into 120 x45mm. This gives a 10mm overhang on each side of the 100mm posts.
One of the newel posts at the transition from landing to top flight. That's the tenon on top awaiting the handrail which will be housed onto it.
The posts were cut to length with tenons on top, and the corresponding housings cut in the underside of the the hand rails. The interesting part was the angled corners of the landing handrails. In one of these brainwaves I have in the dead of night, I resolved how to do the joint... a beautiful mortice and tenon joint. In fact, a stub tenon with a haunched tenon either side of it. And it worked a treat!. All this was done on site. My trusty tenon saw cut the tenons on top of the all the posts, and the tenons on the ends of the handrail returns on the landing. Good to see a saw live up to it's name. I was going to take photos of the joint components before I glued it up and fitted it to the posts ... but once again I was so hooked into what I was doing that I forgot and just assembled and glued the joint. Sorry about that...  Love that glue - Titebond III.

Nice mortice and tenon joint! 27 degrees off 90. There's a long haunch and a stub tenon in there.

That's the other corner. Another very tidy joint, the same as the other end.
Anyway, I was very pleased. The haunch mortice was cut with a slot cutter in the router, and the deeper mortice for the stub tenon was chopped by hand. The tenons were all cut by hand. It was a winner.

Job completed.
When I had completed construction, I brushed the whole structure down and gave it one more final coat of the oil finish. It looked like a million dollars. I then gathered up my tools, cleaned up the site, took a few pics, and drove away. Satisfaction is such a nice warm feeling. Here's a few pics:

View from the top looking down and across.

View down the top flight.

View of the bottom flight from above.

The ground level is yet to be built up and brick paved. The height of the bottom step allows for this. 

This pic puts the stairway in context. Soon there will be a swimming pool in the foreground!

View from the ground level back door.The galvanised steel legs will be painted a colour similar to the jarrah. 
On the joys of jarrah.
Jarrah is such a beautiful timber, and I am lucky that I have been working with it all my life. Jarrah (Eucalyptus marginata) is only found naturally in the southwest of western Australia. I understand there is only about 6% of the original forest remaining. Such a significant timber since European colonisation began here 1829. Until a couple of decades ago, in Western Australia just about every part of a timber framed house from the stumps to the ridge piece were all made from jarrah. It is a is very strong structural timber, very durable in the weather and in the ground, and a very high quality furniture material. Beautiful grain and rich reddish brown colours. The all round dream timber. Yep, I love the stuff.

Much of this stairway was made from recycled jarrah. This material had come from an assortment of buildings and other uses, much of it from a house which was built 80 years ago. All over it, there are the echoes of the former lives of this timber. Rows of nail holes along a tread nosing, testifying to a past life as a floor joist, with the nail holes even showing the width of the old floorboards which were once nailed to it. A couple of old checks in the side of a newel post, speaking of a former life as a verandah post on a building. The residual jaw marks from an old pair of floor cramps, telling of the time that piece of stair tread was once a floor joist. Other pieces were once rafters or ceiling joists, and the spacing of nail holes can often speak of these former lives. It is the echoes of the former lives of this timber which is so fascinating in something made from recycled timber. It is also why I don't fill the old nail holes. Let them speak.

Working with pre-worked timber also gets me thinking about the tradesmen who worked this timber when it was green. That's how these building were always constructed. Green jarrah, while heavier, is easier to work with - and easier to nail. No need to pre-drill the nail holes like I had to! These guys built the houses only with hand tools. There were no power tools. Most of the saw mills were steam driven, and life was different. Simpler times, moving at a slower pace, when tradesmen took pride in their tools and their work. It wasn't just about money and having a job - it was a vocation. An identity. A way of life.

I tip my hat to those guys, and hope I did them proud in the way I re-used the timber they first worked.

Another Earth Carers Woodworking Program.

Over the weekend of 30 April - 1 May, I had the pleasure of working with another group of Earth Carers. This event was funded by the East Metropolitan Regional Council. The EMRC is the regional local government body working on behalf of six member Councils located in Perth's eastern suburbs. Waste Management is one of the EMRC's key responsibilities. The Earth Carers have completed a wonderful free course in waste minimisation and management. More info available at .

Passionate about recycling, reducing waste, and reducing consumption, these EMRC Earth Carers had the opportunity to learn about trees and timber, and acquire some basic woodworking skills. The timber we used was primarily all timber removed from the land fill stream: packaging material, industrial waste, material rescued from kerbside collections, and timber salvaged from skip bins. What a treasure trove of resources! It was an amazing array of timbers from all over the world.

Day 1: Such a wonderful array mostly of kitchen chopping boards, made with beautiful timbers from all over the planet.

The concept is simple : It's one thing to see discarded timber as a valuable resource - it's another thing to know what to do with it. Hence the idea of empowering people with some basic skills to be able to utilise that wonderful timber resource.

Transforming a rough piece of packaging timber into a beautiful kitchen chopping board. This piece of American White Oak took a lot of planing! Nice pile of shavings!    
 Day One we made kitchen chopping boards, and on day two we carved wooden spoons. The main skills learned on the first day of the weekend program were hand sawing and hand planing - the basic stuff of woodworking hand skills. On Day Two we made wooden spoons and spatulas. The main skills were timber selection, and the use of a much wider variety of hand tools, including of gouges and mallets, curved scrapers and spokeshaves, coping saws and english bowsaws, rasps and more. Both of these activities help develop a real appreciation for timber and the traditional tools used to work and shape it.

Paring the spoon bowl smooth with a gouge.

Cutting the curved outline to shape with an english bowsaw.

The wooden spoon activity is one of my favourites, and is always very popular. It is a fantastic way to learn to work with the grain rather than against it,  to get to feel the wood as you work it. The funny thing is that there is often a difference between the planned spoon and the finished item. A bit of wild sawing here, an over-zealous bit of spokeshaving there... and next thing you know the handle now has a curve, or the bowl has taken on a different shape! At the finish there are no two spoons the same - and a wonderful array of  individually handcrafted beautiful spoons!

Day 2: A beautiful range of wooden spoons and spatulas.
 It was a great weekend. Lots of fun, a happy and enjoyable bunch of Earth Carers, and lots of energy and enthusiasm. For some it was the first time they'd done anything like this... for others it was the second time and a chance to build on their skills. Either way these bods will never look at a discarded piece of timber the same way again.
Congratulations to the gang for a job well done!
