If you're patient and use a good soft face hammer, like Wiha makes, you can get good results. In this photo the top two backs are made by hammering, the rest are pressed. It took me the better part of a day to make 1 back by the hammering method. I made a dozen pressed backs in an afternoon.

Yes they are.
Sorry for the delay, I have been busy making a workbench.

At this point I am stopped on making the backs. I killed my TC bandsaw blade by cutting stainless. I plan to post an article here covering my conversion of the single phase single speed wood working saw to three phase variable speed wood and metal working saw. Still waiting for parts.

I started posting the bandsaw conversion under the appropriate thread here for those who are interested.

One afternoon recently I had occasion to use my Wenzloff & Sons 4 t.p.i rip saw for a small project. I have long been aware that Mike W. is known for making tapered saw plates among other things. The light just happened to be right while I was cleaning the saw and I saw it: I could see the machining marks of the tapering and I knew in an instant exactly how he had done it. I won't reveal the secret because I think it would be inappropriate to do so. Nonetheless, I had discovered his secret. I at once began thinking about how to reproduce, or if possible better the technique. By and by I eventually realized how I could make tapered saw plates and, in my opinion, make them better, faster and cheaper.

Today I put the proposal to the test. These are the results.

The steel is 0.025" 1095 cut to 12 and ~20 inches. The depth of both plates is right at 5.5". I applied my method first to the 12" plate. Here are the results.

At the proximal end (nearest the camera), right at 18-18.5 thousandths:

18.5 at the proximal end.jpg

In the middle:

And finally at the distal (furthest from camera).

So far, so good. Now I tried it with the ~20 inch plate.

Proximal:

Well, I can't get photo's to upload just now so I will add more later.

Cheers,
Rob

Good guess, but not in my case. When the upload facility is working better I will post more pic's and measurements.

Rob .. if you're having the same issue I've had for a week or more, you can still upload 1 photo at a time - which is a pain - using the Basic Uploader option.

It looks like you are 'grinding' uniformly along the length of the blade? Not like the classic handsaw with the semi-radial tapering from the tip?


I posted some videos on backsaw.net of japanese knife craftsmen with biggish wheels grinding away ...

I wonder if you could "cook your own" grinding wheel to come up with something say 18"x4" ?
Or just shape a piece of limestone and see how it goes?
We have a poured limestone tile here that I was flattening course oilstones on 3 years ago when I was just started learning enough to be dangerous.

I think Ray & Josh were experimenting with taper grinding on the surface grinder. I wonder what the results ended up being?

Hi Dale, I daren't do any grinding other than bevel chisels...( well actually Josh is doing those ) but I might break cover and do a quick test one of these days..
