Saw Anvil construction?

Post by Gavin Longrain » May 16th, 2017, 11:21 am

At Bodgers Ball 2017, Sawman brought along a wonderful saw-anvil.
Dolly Chapman, our class tutor, has not got one and tells us she flattens saws on medium-density fibre-board ( aka MDF) on a level part of her concrete garage floor.
Question: could I fabricate an effective portable anvil from concrete poured around a reinforcing bar frame?

Because I will facilitate more saw-sharpening courses at field events such as Bodgers Ball 2018 some portable anvil will be v useful indeed.

Gavin,
For a portable saw anvil I don't think a concrete anvil would be of much use. The anvil in your photo looks like quite a nice anvil. To be really effective a for all uses in saw straightening and tensioning an anvil needs to be harder then the saw. For complicated bends, twists and cups you really need a good cross peen hammer and hard anvil to get the saw to bend in the direction needed to end up with a straight and serviceable saw.

Here is a possible portable saw hammering set up. It would be easy to move around and be quite effective for saw work.

This may have been a fork lift tine, it is very hard. I know that John S. uses a larger fork lilt tine for his anvil/bench but for portable use it does not need to be as large as John's. I've used this little plate to correct bends, twists, cups, humps and bumps with good results. For twists you could rotate the plate to follow the needed hammering path and to correct a cupped saw the plate could be placed inline with the long axis of the saw.

Factory made saw anvils are not that rare over here but may not be that common over there. If you have a "normal" saw anvil it is not hard to set up as a portable hammering station. Do a Google image search for "saw anvil" for some more ideas. Anything hard, and flat with some weight should work.

Jim,
Just what I needed. Thanks. As ever: you thoughts are bang on the money as we used to say in Australia

I couldn't get my hands on a big block of steel or forklift fork, but I went to a local iron works and picked up a 12 x 12 x 3/4 square of steel plate. Not hardened, but it's held up well for the past ten years. Holes were a feature it came with and are handy when lifting it.
