cutting large round stock

Recommended Posts

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.

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.

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

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.

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.

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.
