October 17, 201312 yr yesterday i had to cut a piece of 1 5/16 round stock. when i put it in the vise on the bandsaw i couldnt get it tight enough and it kept spinning. i cut a piece of old inner tube and wrapped the stock with it and then clamped in vise. it held nicely and i was able to complete the cut.
October 17, 201312 yr Welding students cut A LOT of pipe on our school bandsaws. I mean 200+ linear feet of 6" Schedule 80 made into 3 inch rings every semester. The only way to get a grip, hold it square to the blade, and not let the blade dig into the hydraulic vise jaws is to get 2x6 wood scraps from the Construction class dumpster. We use them as spacers between the jaws and the pipe. At 100psi clamping force, there is no movement of the pipe.
October 18, 201312 yr Greetings Seldom, Sounds like a piece of line shaft.. 1 5/16... I do it all the time with a porta band... .... Use a wrap around and a silver pencil to mark and have at it... Forge on and make beautiful things Jim
October 18, 201312 yr Backing off the feed pressure ought to do it. I use my band saw all the time and too much down/feed pressure is usually the reason for a straight piece shifting. Tapers need spacers or shims or the vise won't hold them securely no matter how tight. Frosty The Lucky.
October 18, 201312 yr I have a chunk of angle that I welded a pad on to that I use when clamping round stock in the saw. My regular computer is down so I swiped a similar pict off the web that shows what I did. The angle allows you to get a bit more "grip" than just the flat jaws would alone, but I will often still back down the down/feed pressure as well.
October 18, 201312 yr DSW, that is a jig that I will have to copy! Cutting out bad welds to re-use the pipe is an ongoing issue, and that could solve it with one piece.
October 18, 201312 yr Grumpy you might find some useful ideas in this thread where I swiped the picts from. The OP is a welding instructor and often has quite a few great ideas and tricks up his sleeve. http://weldingweb.com/showthread.php?87051-Do-you-have-your-part-correctly-clamped-before-sawing-it
November 1, 201312 yr Used c-clamp for positive clamping. Try the trick of turning your drill press vise upside down and clamp the stock with it laying on the table.
November 1, 201312 yr Good tip seldom. But next time try a hot cut hardie on the anvil, its easier than you may think.
