Default Router bit bushing

Id like to know If anyone can tell me where Id be able to find a 1 3/4" O.D. bearing with a 5/16" I.D . Im trying to set up a 1 7/8" slotting bit to cut a 1/16'' deep slot.

Hi Dave

Have a look at MLCS Woodworking Adaptor Bushings and Ball Bearing Guides and scroll down.

Cheers

"Use The Fence, Luke, use The Fence." (apologies to Obiwan.)

If you have a router table, exposing just the 1/16" of the bit through the fence is easy. For hand-held, using an edge guide is another option.

I guess more information would be a help. Im trying to slot the frame on a fishing net and have to follow the cures and bends of the frame. Useing the fence isnt an option and a hand held is very shaky running on the thin edge of the frame. I appreciate all the thought and options, I just cant come up with the right solution.

Dave,
What thickness does the bearing need to be? Would it be possible to use a slotting bit with a smaller OD? How wide is the slot you are trying to cut? How about using a 1.75" OD bearing with the smallest ID and then use a bushing to get you down to 5/16" ID?

Darrin, I think that would work, if I could find a 1.75" bearing. Im trying to cut a 1/16'' wide slot 1/16" deep. If I could find a slotting cutter with a smaller OD that would work too, but so far havent had any luck doing that. Thanks Dave

Hi, Dave. Is there an industrial supply store near you, say a company called Motion Industries? they sell all sorts of bearings. They might get what you need. You are best to make a jig to hold the frame and steady the router. Just a thought.

A person can never have too many tools!

Dave,
BOCA Bearings and VXB bearings both have 1.75" bearing. I think they are going to be too thick though.

Dave, sometimes defining your task can be difficult. You mentioned the slot needs to be 1/16" deep; how wide does the slot need to be? How many of these nets are you planning on making? If this is a "one off" project the best answer might be different than if you plan to produce a large quantity. From what you have described it sounds like a Dremel 1" slot cutting bit with a collet adapter should be perfect for the job. You can easily make a collar to fit a standard guide bushing to gain your exact depth of cut. You can always make multiple passes to increase the depth or width of your cut.

PS: You can most likely get away using a composit wheel to make your cut with a small amount of burning. Here is a link to a $10 solution to your problem: http://www.harborfreight.com/80-piec...kit-97626.html
