    Question Need help to build wire band saw

    I want to build (DIY) a horizontal band(wire) saw using a fine (.035") SS abrasive wire (instead of a blade) I have on hand with about a 32-40 inch cutting length and a 6" throat. Question is what kind of a motorized drive wheel and other guide pulleys will I need and where can I obtain them?

    If you've already got a bandsaw like that, all you need are the right tires and guides for your wire. I'm not sure what exactly is available or what works best, but you might ask a manufacturer of diamond wire saws like this one: https://www.well-dws.com/en/ Of course, they might tell you to just buy one of their machines...

    I guess I would cut a V-groove on the drive and idler wheel, then build a ball bearing guide for the wire at the cutting area. Maybe use a V-groove wheel as the guide wheel. Maybe something like this https://www.mcmaster.com/v-groove-wh...track-rollers/

    Anyone who would like to help me in this project is most welcome. This is intended to be a productive and potentially quite profitable endeavor.

    Figuring out how to guide the abrasive wire is probably the hardest part. Just about everything I can think of to use wouldn't last long. Maybe you can find a cheap source for rubber wheels and just keep replacing them as they wear through. How do the guides on commercial diamond-wire saws work?

    Re: Need help to build wire band saw

    I need to add here that the wire does not actually have any abrasive grit but is a "dual twisted" wire - one wire tightly wound around another strand of the same wire; is Intended mainly for cutting relatively soft materials (as I will use it for), however I imagine it will still wear on any drive or guide mechanism but likely less than a wire with imbedded abrasive grit.

    Searching on line for any information on such a saw machine or technology seems to turn up nothing* - but then, I'm not the greatest at online work! Yes there are diamond saws but I'm not using a diamond imbedded wire.

    *I find info instead on large machines for cutting large stone blocks - I'm at the other end of the scale.

    Looks like I can get v-groove guide bearings for the wire on eBay - only need some kind of drive roller* to move the wire via a small motor. Any advice?

    I can apparently easily make the wire into as continuous loop (for the band saw) by simply twisting the 2 ends together.

    *I've noticed that feed rollers for MIG welders seem to be made for similar size wire. I should only need wire speed of from 1-3 ft./sec. Variable speed motor drive would be great.

    Re: Need help to build wire band saw

    What is this machine for? When you started this post you were talking about abrasive wire and a band saw. Now you're on to twisted wire and some kind of MIG wire drive. What do you think this wire is going to cut? Some kind of foam that can't be heated?

    No, you can't simply twist the 2 ends together...

    I already tried making a loop by twisting ends together and it looks functionally fine.
