Making A New Turning Saw Part I


My "prototype" turning saw finally died. It was a quick and dirty project that was never intended to last. The original idea was to work out the bugs in the design, and then move on and make/use a nicer saw. It didnt end up that way. In fact the prototype was superior, and was my turning saw of choice over the years while the "nicer" saw hung on the wall.

Heres a shot of the DOA saw:


The epoxy that held the brass pin in the handle finally let go. I could just fix it, but as good as this little saw was (way better than you might guess from looking at it) Ive been wanting to build that nicer saw that really works too. I though this was probably the time.

The new saw will be made of oak. I still have some left from the broken library chair episode. After making some cardboard templates, I traced the design onto the stock. I decided to make the handle convex where my hand will hold it, much like a panel saw handle, rather than the more standard concave bowsaw handle. Im not sure if this will end up being a good idea or a bad idea. Ill know soon enough.


I prefer to do the mortising while the stock is still square. The setup is easy with the holdfasts. The big (giant!) mortise chisel and mallet do the grunt work and the smaller chisel is for cleaning out the chips and flattening the bottom:


The mortising sequence - start in the middle and work to one end (not quite to the layout line):


Back to the middle and work the other way:


Continue until the mortise is deep enough, then clean up the ends:


After laying out the tenons with the same gauge setting used for the mortises, I cut just outside the lines with a backsaw and trimmed with a shoulder plane to a snug fit.


Heres the saw so far - looking very chunky in its unshaped form:


In Part II I will shape the frame parts, make the blade assembly and create the tensioning system. After that, Ill try it out.

If history repeats itself, Ill be regluing the prototype in Part III.

New Tenon Saw

After much research and deliberation I have finally got myself a shiny new and very large Tenon Saw. 
For ages I have felt like I have needed something bigger than my Lie Nielson Carcass & Dovetail Saws, but I couldnt decide on the size or whether it should be sharpened Crosscut or Rip. 

As far as size goes, it seems the wood working superstars recommend something at least 14" and preferably larger.

Most of my cutting is to length and therefore requires a Crosscut sharpened saw but larger tenons require a Rip sharpened saw and my Dovetail saw blade is only 1-5/8" (4.12cm) deep. I certainly didnt want to buy another two saws, so which saw would provide the best coverage and compliment my existing joinery saws? 

I came to the conclusion that I should get a Rip sharpened saw which could also be used across the grain if required and decided on the Lie Nielson 16" (400mm) 11ppi Tenon saw (reviewed here). 

As I found previously, I had to spend a while learning to use the new saw as it initially jumped about in the kerf. This is a large saw and a lot heavier than what Im currently used to. The weight, combined with the extra height of your hand above the cut (blade depth) and the angle of the (dangle) handle meant I had to saw very slowly and steadily not applying any downward pressure at all other than the natural weight of the saw while my body became familiar with the movement. After quite a few rip cuts in some scrap Pine I finally got the hang of it,  and found the saw to cut fast and track straight as an arrow. No doubt I will further improve the more I use the saw. 

I was also pleasantly surprised at how smooth cutting the saw was when cutting across the grain, I will certainly be able to cut wider and thicker boards to length on the bench hook when my Carcass saw is struggling. Anything that is to big for this new 16" beast can then be handled with my panel saws.

So ... all in all I feel it has been a good purchase and my Trinity of Joinery saws should encompass all my needs, probably for the rest of my life! In fact I would say that my nest of saws is now complete.

I would be very interested in other peoples opinions on my purchase and what saws other people use.

An afternoon of boredom led me to find a use for some kitchen surface chip board and some old reclaimed pieces of Pine to make a quick and dirty bench side saw stand. Its not pretty but it did get my freshly sharpened saws off the floor and out of harms way.

Other new additions to the tool collection, once again courtesy of my girlfriends mum. These include two Marples chisels 1" & 1.5", the larger of which is very rusty. I will probably use these for jobs such as cleaning off dried glue etc. saving my Stanley chisels for best. Id love some Lie Nielson chisels one day they look gorgeous!

A fret saw (needs de-rusting) and pad saw (no blade) and a small mallet. The mallet head is actually made of a roll of wood and will make a good assembly hammer.

Anyway thats enough for now... time to build something soon!
