Dream Saws Seriously
Careful what you wish for ?
In my wood shop using only hand tools to build furniture, back saws are without a doubt one of the most important and most frequently used tool than any other outside of perhaps hand planes. Today we have the luxury of purchasing pre-dimensioned, quality lumber for our projects making my full size panel saws second in most cases. I still have to spend the time to cross-cut and rip stock, but the backsaws are where the real joinery happens.
I use my Lie Nielsen saws for most of my work but also have a couple of nice reconditioned antiques. One of these vintage gems is an old R.H. Davis Co. and was given the works by Mark at Technoprimitives, its a great saw and a real pleasure to use.
Over this past year Ive designed and manufactured thirteen pieces of furniture in my small workspace and through this hectic schedule realised some limitations in my current hand saw arsenal. For example, when cutting dovetails in carcass work I like to use the method of clamping two surface pieces of the stock together and cut the tails simultaneously. When dealing with stock 3/4" or better in thickness, Ive often found myself wishing my Lie Nielsen dovetail saw had a longer plate. I absolutely love this saw for general dovetail work like drawers and single board thickness sawing-but dealing with 1 1/2" to 1 3/4" material shows limitations. For this reason Ive been speaking to a couple of hand saw manufacturers and would like to develop a dovetail saw that has a longer saw plate.
I think most people associate a longer saw plate with less TPI (teeth per inch) but on the contrary, the design I think would suite my work best would actually be a finer tooth pattern. The Lie Nielsen comes standard with a 15 tpi or for easier kerf starting they now offer a Progressive Pitch Dovetail Saw which runs from 16 tpi at the tip down to 9 tpi at the handle position. I havent yet tried this model but have heard great things about it.
The dovetail saw Im thinking about would have at least a 10" saw plate with a slightly finer tooth count, say 16 tpi over the length. The progressive pitch would be fine if I can convince anyone to build one for me! With this size plate I began to worry that the extra length would mean of course extra steel or brass back in turn making the saw heavier. Not a plus when cutting dovetails in my eyes...or hands. Im not sure how this will play out but I have a couple of ideas in mind; one being a kind of hybrid mix of dovetail saw with No. 9 half back saw plate. This would essentially make the plate the desired length without the extra weight of the full length back.
Im still in the developing stages of this and need to work more on it...any comments or suggestions are always welcome!
So thats my dream dovetail saw but unfortunately Id also like a larger scale back saw for cross cutting long miters. Ive seen pictures of the really large plated back saws used in miter boxes...Roy Underhill is famous for that one, but would like something in the 16" range. Anyhow, the same thing would apply, a longer saw plate with a finer tooth pattern. For this one I wouldnt mind the extra heft so I think the back would run full length.
Now heres the cool/freaky/strange and then cool again-part in all of this:
Last weekend I stumbled over an add in the local buy and sell...it simply read 2 Antique back saws for sale- $15.00 and $20.00.
At that price is was worth the gasoline to drive across town to see them. A friendly gentleman greeted me with the two saws saying they had been sitting in his cottage for years.
Well when I first saw him hold up these two saws I was a little bit like...
"O.k. wheres the hidden camera.?"
I took them home and simply gave them a light cleaning with metal polish and fine steel wool to remove a bit of the surface dirt and small amounts of rust that had collected on them; not more than 10 minutes on each and they were shining like new dimes. The handles needed only a fresh wipe of oil and Ill re-sharpen them as soon as I can...
So now, heres the hook, one saw is a closed handle, 10" back saw with a 1 1/2" depth of cut made by Disston & Sons the better part of 100 years ago. It does have a small crack in the handle but doesnt seem to interfere with holding it...nothing a bit of glue wont fix.
The other has a 16" plate with 3 1/2" depth filed cross cut at 14 tpi. Its by Shurley & Dietrich, a fine Canadian saw manufacturer from years ago. Oh yeah, the little carcass saw, which The Disstonian Institute mentions: "While not marketed as such, the 8 and 10 inch saws make respectable dovetail saws when filed with 14-point rip teeth." is indeed filed at 14 tpi-Rip tooth.
While not exactly the saws Id been dreaming about these past few months, (cutting a couple thousand dovetails will do that to you) they are an incredible find. A couple of pieces of history to inspire me, assist me while Im working wood and educate me in designing a couple of new backsaws someday...Careful what you wish for? Ill never get them designed now!
