    Is this a trick of the camera, or an artifact of how it was bent?
    It seems one side is thinner.
    I

    Yes that is a trick of the camera. The front edge is chamfered. You only see the chamfer on the side visible in the picture, making this side look fatter.

    I'm no metal-worker (wood-worker either ) ... so probably easily impressed ... but I thought this was a good little video.

    Nice clean work practice ... and potentially modifiable to the brass backs ... in the sense of a small hydraulic jack and a form?

    Note to self ... don't forget the actual video.

    Default My folded saw back

    Hello to all. I am new to the forum. I have been working over the past couple of years to produce saw parts and have finally made some progress. As you can see the process was not entirely painless but the last two photos show the end result.
    I'm thinking of making some backs in stainless steel, does anybody have experience with it?

    Welcome to the forum Rob. Very nice work with the folded backs. I would imagine there's a lot of hard work involved in the process. Kudos for doing the same with stainless.

    Thanks Stewie,
    Yes, a lot of work, about 45 tons worth in fact. I finished a couple of 12" backs this afternoon before shutting down to do some maintenance on the hydraulics. Got myself sprayed with fluid as a bonus. Wife's in the photo studio now but I'll put up a photo later.
    Cheers,
    Rob

    Welcome to the forum Rob.

    Beautiful work!

    I'm planning to slit some stainless soon to see what it's like for saw backs, what thickness of stainless did you fold? What grade 316?

    Hi Ray,
    12 stainless back 123113.jpg
    I used 304, 0.083" thick. Here are some pictures of a 12" back made today.

    Very nice Rob! And in stainless no less, you're a brave men! I understand you use a 45 ton hydraulic press? I have made a few backs with a hydraulic press too in the past, which makes for a lot less sanding and straightening work then the hammering method.

    You close them all the way at the blade end. Is it hard to insert the blade afterwards?
    They look quite oval, which reminds me of my Spear and Jackson saws, in contrast to my older English backsaws which are a little flatter. The Spear and Jackson has the very end crimped close, but I like the look of the open end more.

    Hi Corneel,
    Yes I press them. I clamp the plate between two blocks of soft wood in a heavy vice and drive the backs on from the end. Not hard at all if I stop at the point where the blade has a bit of an opening. I chamfer the edges of the blade steel to ease the process. A little lithium or MoS2 grease helps too. I tried hammering and a bar folder too - both were inferior in my opinion as there was a lot of post folding work to be done and I wanted to be able to make more than one back a day.
    Thanks,
    Rob

    Default Bronze?

    Does anyone here have experience in forming bronze? I am thinking of using 0.125" bearing bronze (392) to make some backs.

    Hi Rob, What gauge plate are you using for the blade? It sounds like your starting at one end and sliding the plate down the full length from that end (Side Entry). Or do you have the blade sitting on the brass aligned in position and start hammering in on one end and move along the full length pushing it down until you reach the other end? (Top Entry)

    It looks like I have to gain access to a press again. Oh well, hammering works too, just a bit more work.
