Bandsaw jig for trimming blank corners?

[John Gray]

I am trying to trim the 90 degree corners off of some square acrylic blanks and/or wooden ones. Has anyone made a jig to do this or seen where I could information on such? My idea is to make something adjustable for different size blanks that slides in the miter slot on one of my bandsaws, I have a 14" saw and a smaller Craftsmen the will only cut something that's under 3" high.
HELP!!!!

Use a block of wood with a V the length of it and lay the blank in that to hold to cut corners.

I do believe that there might be a tutorial in the library. I know that there have been several jigs posted here before. Let me see if I can find one for you.

Hi John,

I think that I have put pics of my jig on this forum somewhere, maybe on someone else's post but I can show you what I've done for the pen blanks and it works really well, particularly the improved version on my first one. I cut (remove the square corners) a lot I mean, hundreds at the time sometimes, and it takes no time at all to do a few, just magic...!:wink::biggrin:

You should be able to work out how to do it, if not shoot any questions you have and I will try to help you through...!

Now..., where did I put those pics...???:biggrin:

OK, found my original jig pics...! put these ones first and I will come back with the improved version...!:wink:

Cheers
George

Yeah, I've though so...!

I have actually put it all together in a thread some time ago and here it is http://www.penturners.org/forum/showthread.php?t=55143

Copy away and have fun...!:wink::biggrin:

Cheers

How large are you trying to go? You can't turn the corners off on the lathe?

It depends on what I'm turning. In the case of pen blanks, I just put them on a mandrel and turn. Likewise bottle stoppers. But if the blank is larger, I generally prefer to knock the corners off on a saw.

Actually, the safety instructions that came with my lathe say that if the blank is larger than 3", the corners must be cut off before turning. I tend to take published safety recommendations seriously.

John; I just sand off the corners using a drum sander in my lathe. I do just before turning when the blanks are mounted on the mandrel.

You could knock them off if you have a disc or belt sander..just makes a crap load of dust...never said it was perfect

I bought one from Hut years ago when I started turning and it is brand new never used on the shelf. Wish that it was worth shipping I would get rid of it.
