Does anyone know where I can buy a bi-cutter? Its a graphic design tool that allows you to cut parallel lines. I need one so I can cut same size trim rings. The tip is like 2 exacto blades on a circle that is fully adjustable by a screw. Thanks if you can help me.

Hobby Lobby has them. Or they did last time I checked.

But there is a better way to cut identical trim rings. I only say this as I've tried the bi-cutter and didn't find that it worked very well or as well as I had thought it would.

Do you have the Rodmaker issue on basic EVA grip inlays?? If you measure the width ring you want and put a piece of tape at the edge of the measurement and then set the grip piece spinning in the lathe, you can draw a piece of size D thread between your hands and lower it down into the grip at the tape edge and it will cut the EVA piece like butter. This is WAY quicker and easier than the bi-cutter. With a little practice you can even knock out 1/8 th inch trim rings with any measuring. You can actually eyeball them and knock them out one after another in mere seconds.

Glue 2 X-Acto blades on opposite sides of a craft stick..glue 2 sticks together..glue blades on the 2 outside edges...repeat with 3 sticks....you now have a set of 'bi cutters'. Use these to cut just deep enough to mark the EVA( do not cut all the way to the mandrel)..then use thread ,or dacron casting line ,to do the cutting apart of the rings.

use 5 min. epoxy to glue this stuff. Also,hold the thread with pliers..do NOT wrap the thread around your finger !

I do use the thread when Im cutting EVA, but I want to try to cut burl cork with the bi-cutter. I have the jig from custom tackle, but it only cuts the ring in half, I want them in 1/4s. I thought maybe the bi-cutter would get me what I needed. What I have been doing is taking the checkerboard/diamond jig and using that. When you put a ring into the jig, there is a lip at the top. I put another ring there and cut flush with the top of the jig. I works, but a lot of times one side of the slice is a little higher than the other because of the motion of the blade. I just figured a bi-cutter would do it perfectly. Thanks again.

The bi-cutter is poor at cutting cork. You'll burn the cork before you get it cut all the way through.

Take the custom tackle jig and have a machine shop slice an additional slot in it at the 1/4" mark. Then you can cut them in half or 1/4", whatever you like.

Buy some washers about 1" in diameter. Just stick one (or a few) in the jig before you put the cork ring in. You can slice them as thin as you want.by changing the number of washers you use

Thanks a lot Mike., I never thought about that. Awesome.

Bi Cutter @#$%&. IT wanders, vibrates, doesn't cut clean. Better to use it as a template - start teh cut, then use some other cutter, my preference would be a Xtra Fine tooth saw sold by Exacto to finish up the cut.

With EVA - just make a million skinny trim rings and match up thos with qual width. After doing 2 or 3 you should be able to cut them the same width by eye.
