It looks in decent condition apart from the dodgy paint job - it has the original jaws, nothing looks battered, looks square.
I wouldn't be suprised if it reached £250 if there are at least a couple of bidders who both want it, and i'd happily pay that for an Edwards. Good luck trying to bend what that one will with some new MM junk. That one will last forever.

Just made this for bending solid 8mm bar i can repeatably do the same bend everytime still need one for flat bar.
whats the fastest and a repeatable way of cutting the round bar before bending, im thinking its using a metal Guillotine but how long do the blades last, do they dull???

do what hot?
instead of having to cut a full length of 8mm bar im thinking of a guillotine the one with hole in making a basic stop guide so all i have to do is pull the rod through the hole until it hits the stop guide then just guillotine it, not sure how long the blades last on them though
not for sale ,if you were nearer,youd be welcome to use it, free for a member.

I made a slightly tougher version of the MM bender. Does 40x10 without much trouble. Don't think I allowed enough room to put 50X10 flat in it.
My bench shear will easily cut 8mm rod. Not got the hole cutter version, but in the normal jaws.

Just tried a cut and there is a bit of distortion at the top of the cut. Bit like if you had touched it with a flap disc at 45°.
I have had the shear over 30yrs and around 2003 treated it to a new of blades. But I grind the blades from time to time as they suffer from use of stainless and get nicks.
Think if I was doing your bits I would just use the disc cut off saw. A quick twiddle on the side of the disc would take off the flash.

How would you do it?

Take a guide from the one linked in #18. Put a post in the hole, locked in with the grub screw. Mount a block with screws acting on a plate to clamp the work against the fixed section.

yeah thats what i was thinking i would of been great to get it close to original though, i have been looking and its a solid block of steel with an offset hole and there is a long pin/post which is also reduced sized and offset at the end and so when you turn it it pushes the block to the fixed plate clamping it then the grub screw would i assume once tightened lock it all in.
i cannot complain he said i can have it for a tenner or it was going in the scrap bin but i know the part would of been somewhere around but it was to rammed in his workshop to look for it.

If you have a lathe, how about an eccentric bush in the block that cams the block to the work. Have a lever on the bush and some thread on the top of the post to tighten it down. (Bit like you said..) The hole in the block bored as you say, offset, so you have four different measurements to the faces, to allow for différences in the thickness of bar. I would rather have a big nut on top of the post, than rely on the grub screw to tighten the post from turning.
Really good tenner's worth.

to be honest i have a lathe but still new to me really so i know only real basic stuff it does seem in good nick it has had a weld repair of the removable jaw i think you can see in the pics but i have turned the jaw around it doesn't seem like its been abused.
I wonder how much a machine shop or someone with more knowledge than me would charge for the block and the pin to be made like the original one when new because its a shame for me bodge it
i have looked and there isnt really any videos on eccentric offset turning on the lathe i assume you need a 4 jaw i have not got only a 3.

Hummm. You could turn the bush in the three jaw, then drill the eccentric hole for the post in a drill press? The block could be held in a three jaw with bits tacked on to put the hole off-set. It doesnt have to be very accurate. Or tack it to a round plate, but off centre and hold the round plate in the jaws.
