I'm in the final stages of my build and have done a 1st cut. It's very evident that I have a few issues to sort out.

The main one is far too much weight on the blade. Most of the builds I've seen involve adding weight to get some more bite from the blade but I need the opposite. Anybody know if there id an ideal downward weight for a hacksaw?

And, I'm cutting on the push stroke and think I would be better to cut on the return stroke. This is simply a case of reversing the motor but also the main coupling is on a RH thread and will undo if I reverse the drive so a bit of welding will be required.

Apart from that an a few small mods and tweaks it should be completed soon.....ish.
