Cold cut Chop saw?

[jinjahbiscuit]

Utukku, there was a bandsaw up for grabs on the forum just a couple of weeks ago, in your area too, £80. Might still be available, check the used equipment section.

Theres never seems to be any forum love anymore for a old power hacksaw as a option for general workshop duties and they pop up fairly cheap now and again if you keep looking for this reason. Theyre a bit slow to cut sometimes but I wouldn't be without mine, I just set it off cutting and wander off and do something else, then I hear a thud a bit later as the offcut drops into the bin I leave alongside for that purpose. I regulary jam large diameter parts into it, use it to saw up car halfshafts etc, though I did have to replace the blade this year after only two years use. Its quiet too, just this rythmic slish slish noise. I have a vertical bandsaw and various other options, but the donkey saw is the one I use the most.

I think that might be because no manufactures make them (that I know of) apart from huge ones that most people couldn't fit in their shop. Maybe someone should be making small ones like the small rapidor's again. And also, like you said, their slow but most people seem to forget they could do something else whilst its cutting (like tidy up).

MrFluffy, I thi k it's probably size and portability that kill them, my dewalt lives in a little hole under some shelves, I wouldn't be able to swing a cat if I had a power hacksaw or bandsaw in there!

Dan, what model and price point is your dealt?

 

[MrFluffy]

My power hacksaw is one of the smaller ones in fact the same footprint as a smallish horizontal bandsaw, if you could find a way to direct drive it with the motor behind, it could be tabletop as myfordboy's on youtube is. As for portability, it now has castors on the back legs and rubber feet on the front so I can just lift the front up and wheel it out the way and the handle folds down to reduce stored height. As mentioned the rapidor's are compact also.

I NEED a picture of your one. And thanks for clearing up the whole coldsaw thing, everyone had me wondering if evolution made a real coldsaw.

Nah
Here is mine: There was a thread here, but not easy to find after a software change.

It has a bit more of a guard on the blade now. The belt system is to get the speed down to the 1400rpm for the blade from 2800 of the motor (ex jetwash) The belts are what I had in the bin, so hence the high idler.

Wow, that is very nice. How accurate is the cut from it? And also, did you buy or make the shafts (or just had them lying around

Thanks.Square enough for fabrication with tube, though I cut a lot of 15x40mm bar too. The yellow shaft was bought, but for a previous stone cutter. The layshaft is home grown and the toothed pulleys are off engine cam drives. The reason for the layshaft, is that I didn't want the big pulley on the blade shaft for the reduction. It would reduce the depth of cut.
So, one to two on the layshaft and one to one on the final drive. Worked out with no fettling, though I might improve the pivot. The balance is about neutral, so the return spring is to make sure it stays up.

I make most of my kit, as it is cheaper and I get what I want, rather than a compromise. Plus I never know if it will get used after the current job. Not including welders and lathes, pillar drills of course. Though I am tempted to make a mobile welder from Shenion's ideas.

Does that corse blade cut steel bar ok??

Yes, it goes through the 15x40 mm OK. There is not an option for a finer blade on the Evolution list. I use a pot and brush of cutting fluid, but it would last better with a continuous flow system. Since I built it, I have lost or chipped four teeth on the blade, acceptable for the use. Note to self: order a fresh blade..

interesting. I have a slow speed real chop saw and it has an HSS blade but does not seem to last that long. Trying to find a cost effective option as a replacement...lol

You can get the HSS blades re sharpened over and over until they are too small to be useful, then you can cut them up to make all manner of things like lathe tools etc.

Mine has lots of teeth to the inch whats the benefits of finer blade and how course a blade can you use to cut steel??

Is this like the blade you have?

How course or fine the blade needs to be depends on the material and the speed.

My saw has two speeds so I use a medium tooth count blade slow for thick material and fast for thin material.

Mine o nly has one speed. Quite slow. Its a bit like this one only smaller at 8 inch blade.

What's the baleigh industrial machine in the back, I've often admired their stuff.

When you say your blade doesn't last long, how long? I tend to get well over 1000+ cuts out of a blade before it needs sharpening. That's a 14" blade so I would expect it to last longer then a 8", that will also depend on what your cutting as well.
