I need to make a long V block... I have a 1 5/16" chamfer bit with the bearing.Can I take the bearing off and use it like a V bit safely? Never even thought about this until now.Dont want to buy another bit if this is safe to do.TIA!

Definitely want to be safe!!!!!

If you insist on using that bit, cut a grove first the width of the bearing . Don't cut without the bearing because there won't be anything cutting at the bottom of the V. And don't cut full depth all at once, go 1/4 inch per pass or less.

Buy the correct bit.

I make V blocks by cutting 2 45's on the table saw. Keep it long and then cut to size.

I agree with DrBob -- for a long V Block, cut a 45 degree miter on hardwood blocks of the length you want and glue them together. It will result in a full-depth V.

I would be very hesitant to use a chamfer bit to make a long V block. With the bearing removed, the cutting edges do not come all the way to a point. If you don't need a full depth V bottom, then I guess that doesn't matter.

Personally, I would use either Dr. Bob or Rob's method. On a table saw, rip a 45* miter down the center of a long block, then flip it around and repeat. With a chamfer bit, cut the 45* chamfer down each side of a long block, then rip the block down the middle and glue the two halves back together w/ the V in the middle.

Recently had to make a couple "V" grooves and their mating parts. Used my good old Sears molding head with "V" groove cutter on the table saw. Made some extra pieces as this is a project I may repeat in the future. I do have a 45 grooving bit in my router bit collection.
