View Full Version : Cut the Cylinder!
02-26-2008, 12:57 PM
My first Cut setup. The two previous threads detail the tank roller, and the top and bottom guides. Here is my first fabrication of a cutter. This is part of a 41/2" chop saw stand, (like they sell at Tractor Supply), just bolted to an upright I tacked to the side of this table. It pivots the blade into the tank (see the little lever?). What's not shown is a chain wrench I placed around the threaded part of the neck to advance the tank as the cut-off wheel did its job. I use DeWalt wheels (lots of them)... but this last time I went to grab some at HD they were sold out, and the salesman directed me to the Hilti Cut-Off wheels, which were twice the price, assuring me they out-preformed the De Walts by a factor of x4...Well, in this application cutting this 1/4" Steel cylinder, the Hilti lasted about 4 inches, and was down to a nub, whereas the Dewalt stepped in and went all the way around the remainder of the tank, which is 30" in circumference, so I'd give the DeWalt disc a 7:1 advantage over the Hilti.:p
The cut is not perfect, due to a miniscule alignment issue with my cutter, which can be easily corrected by a more solid 'bedding' That cheapo 'Chop Saw" stand also has slop in its pivot point.:(

Pretty cool idea. So, are you going to motorize the rolling? Then you could spring-load the grinder and start it up and let 'er rip! Or, you could get a chopsaw and bolt that in and do the same thing without going through as many cutoff wheels. Or, you could use a hydraulic system to advance the blade into the cylinder, like the more expensive bandsaws use to apply pressure to the blade. Then a kill switch on the pivoting part would shut it off after it completed the cut. And then...
Oh, why can't I leave well enough alone?

Yeah, we use something simular with a circular saw and concrete forms. Here's one for carbon-fiber or fiberglassed tubes:

Surplus Center usually has those long rollers to build such setups. Both ideas are pretty interesting since I've been trying to figure a way to cut some pipe into 2" long rings.
Is that chopsaw/grinder fixture sold for that purpose or did you modify it for that use? I've got a tile saw but the grinder seems less labor/fabrication intensive for occasional use. I'll have to check TSC,I need to go there anyway.
Thanks for the ideas...

Works for me...can't argue about the price for sure. I was going to use a friends large lathe,but I hate to "mooch" if I can do it myself in my shop.
Want to build a steady rest for my 9" Southbend lathe and got the wild idea to build some 8" steel casters after looking at some built that way at the scrap yard. They looked simple enough.. steel rings..steel plate centers..steel bushing hub... heavy duty rollers.
Thanks for the link.
