Give up and get custom router bit?

Before I order a custom router bit, I wanted to ping you guys first.

I want to create this profile, it’s incredibly small .25 inches high and .5 inches wide. I’ve tried doing it with a roundover to no avail (do both sides then flip it over). The chief issue is that the corners are not the same angle/shallowness.

Any tips/suggestions?

I’ve attached the pic below as well.

How about a 1/2 inch beading bit, cut off from the board, then sand the edges on the bottom or you may find a small round over that goes with a Dremel.

Anything is possible IF you don't know what you are talking about.

How much does a custom bit cost, and how much of the profile do you need?

A bull nose bit with the .5" width will do the large radius. A round over bit with a small 1/4" radius will make the small shape. It will take 3 passes to make your shape and it may get difficult to hold properly to prevent twisting. You may have to hot glue it to another piece of stock for that... I donno?

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Don't bother trying to machine this - the problem is always holding the workpiece and 'chatter' of the machine. Best bet is temporarily spot glue a piece of 0.5 x 0.25 I assume wood to the edge of say a piece of 0.25 ply that you can clamp it in a vice. Take the bulk off with a small plane like an xactor or surform and then sand to finish I use wet and dry paper of different grades glued to a block of wood as you get far more control using this technique.

Custom bits can range from 150 - 300 with a production time of 1-2 weeks.

I'd be half tempted to slice a 1/2" dowel on a band saw and then sand the bottom round overs.

Alexis de Tocqueville was a very smart man.

good idea

If you can cut the dowel down the center line evenly it should work. I would hot glue it to a 1/2" thick straight board so it can't rotate. Then its all set up to run the round overs on the router table..... it should work.....
