I'm going to make a stand for a vise and I will be using 3.5" steel tube. How do I get the ends perfectly straight for welding? I can get a decent cut with my portaband but not perfect. Do I need to get a beltsander? I also want to cut and reweld the scrap pieces for practice.Thanks
Reply:You will not get anything straight and true with a saw and belt sander....What you really need is a lathe....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Cut with your bandsaw and then use a level to get the column plumb with the base.
Reply:Hello kerf, if you have a pipe wrap available layout a line on the diameter of your pipe and cut along the line, carefully paying attention to only cutting through the surface that you have in contact with the saw blade. By "following" the line in this manner it is relatively easy to maintain a straight cut. You can dress-up any major imperfections with a grinder after you have made the cut. This same method can be used to cut pipe that is of a larger diameter than the porta-band will allow to fit in it's throat. So long as you can cut through the thickness of a particular pipe to some degree, you can work your way around in segments and cut the pipe in two. This method also works good for cutting angles on a pipe if you have a pattern that you can draw a line on the pipe with. Good luck and best regards, Allanaevald
Reply:For larger and longer tube my lathe is not big enough to do this. I do however use long end mills on my Bridgeport Milling machine.www.tjsperformance.comDynasty 300 DXHTP 240HTP Microcut 380Hyperthem 85JD2 Hyd Bender and HF Hyd Ring Roller all in one =(Frankenbender)Bpt.

Reply:Hello kidtigger24, I like the "poor man's" pipe wrap, ie., the hose clamp, looks to work pretty good for an application such as the one at hand. Still partial to a porta-band over a sawsall though. Thanks for sharing that video. Best regards, Allanaevald |
