slownrusty Posted November 24, 2007 Share Posted November 24, 2007 Guys - What do you recommend? I have a nice DELTA bench mounted band saw which is perfect for a straight cut on a straight piece of pipe but the blade tends to wander if I have to make an angle cut like say 22degrees. I am using 2.5" diameter piping. What do you guys use - a chop saw? Thanks & Regards - Yasin Quote Link to comment Share on other sites More sharing options...
240hoke Posted November 24, 2007 Share Posted November 24, 2007 I actually just use a hack saw so I can go slow and make sure the cut is straight. use a band clamp to make a straight line and go at it. Quote Link to comment Share on other sites More sharing options...
olie05 Posted November 24, 2007 Share Posted November 24, 2007 How would you go about making a specific angle cut in round tubing? Quote Link to comment Share on other sites More sharing options...

johnc Posted November 24, 2007 Share Posted November 24, 2007 Why would you be making an angle cut on round tubing? Shouldn't all cuts be perpendicular to the tubing centerline? Quote Link to comment Share on other sites More sharing options...
240hoke Posted November 24, 2007 Share Posted November 24, 2007 I have had to cut angles for really tight bends several times if you cut the tubes equal you can make a tight S bend etc. I still use a band clamp just loossen and tilt.

240hoke Posted November 24, 2007 Share Posted November 24, 2007 heres an example from one of my OLD setups. Take a look at the charge pipe going from the i/c to the intake manifold. Thats cut at an angle..... if you see a flow issue there lemme know, I think its better then two 90's. In my next setup I used two 45's and made a perpendicular cut but i still think the S is more aesthetically pleasing Quote Link to comment Share on other sites More sharing options...
phil280zxt Posted November 24, 2007 Share Posted November 24, 2007 I made sure all my cuts were straight and used a hack saw and mitre box. I tried a chop saw, but it tended to melt the aluminum a bit and was a bigger job cleaning up after... Quote Link to comment Share on other sites More sharing options...
hughdogz Posted November 24, 2007 Share Posted November 24, 2007 I have one like this: I found that if you help support the weight while it's cutting so it gets an even lower feedrate, it won't wander much at all. I've cut an 8 degree pie sliver with this method. I know my fab skills are nowhere near Austin's or Johns, but give it a whirl it may work for you. If you're cutting aluminum, it should go through like butter...HTH Quote Link to comment Share on other sites More sharing options...
240hoke Posted November 24, 2007 Share Posted November 24, 2007 If you want to cut certain degrees out of a mandrel you can make a "mitre box" ouf of MDF, cutting u shapes out with a jig saw and layering them up with a flat piece on the bottom so you have a U channel the same radius as the pipe. Then mark off your angle lines and cut through with a hack saw, youll get straight accurate angles everytime. Quote Link to comment Share on other sites More sharing options...
NCchris Posted November 24, 2007 Share Posted November 24, 2007 I cut aluminum angle and tubing on a chop saw intended for finishing crown molding etc. Just use a thin, fine pitch carbide blade and don't try to force it. Use a light touch and it will cute fine, mitered corners and all. chris Quote Link to comment Share on other sites More sharing options...
slownrusty Posted November 24, 2007 Author Share Posted November 24, 2007 Thanks guys! I guess I forget about the good ole try, true and tested Hack Saw! I did borrow a really nice Ryobi mitre saw from a friend and the blade thickness looks like it might really damamge metal as it was cutting, I will have to try it and report back in. The 80-90 tooth blades for this saw is $50, more than I thought. Thanks for the feedback. Yasin Quote Link to comment Share on other sites More sharing options...
Careless Posted November 25, 2007 Share Posted November 25, 2007 regular table bandsaws work ok sometimes too, as long as you make a jig to hold it properly against your fence or with your mitre guage. Quote Link to comment Share on other sites More sharing options...
Metallicar Posted November 28, 2007 Share Posted November 28, 2007 I bought a pipe cutter that cuts up to 3" OD at a yard sale - $5. Just needed a good cleaning and some oil. It does cut soft pipe fairly well. If you just lightly tighen the wheels as you rotate the cutter, it will not crush the pipe. Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted November 28, 2007 Share Posted November 28, 2007 I tried using a 14" chop saw at my schools shop.. and apparently the blade is not rated for aluminum or porous material.. because it clogs up the blade and can cause failure. I hate using band saws.. lol Quote Link to comment Share on other sites More sharing options...
mcmike280z Posted November 29, 2007 Share Posted November 29, 2007 Use a non faros metal cutting carbide tipped blade. the carbide edges are shaped so as not to clog. They cut smooth as silk any angle your little chop saw desires. Quote Link to comment Share on other sites More sharing options...

proxlamus© Posted November 29, 2007 Share Posted November 29, 2007 I used a 14" chop saw yesterday with a blade designed for cutting only aluminum.. OMG its amazing. Too bad the price range is $201 for this blade. But worth every penny. wow. saves sooo much time and amazingly clean cuts w no de-burr necessary Quote Link to comment Share on other sites More sharing options...
