I’ve often come across those fancy brass guide bushing centering pins for routers and could never bring myself to buy one. While building a dado jig that involves the use of a guide bushing I was amazed how much play that bushing actually had. I felt the need to come up with a solution for that problem. As we don’t have a good hardware shop anywhere around and as today is a holiday anyway I made my own centering pin. This has probably been done before but I’ll treat it as “my design” as I haven’t seen and copied it.

Instructions :
1. Find an old dead drill bit that fits your router’s chuck
2. Take a scrap piece of hardwood (I used beech) and drill a hole in it with that same bit or another one of the same diameter if it’s too bad :-)
3. Epoxy in the drill bit at a distance to the end of the bit that will allow you to center the bushing
4. Put the drill bit into your drill press, turn it on and shape the wood. I used an angle grinder with a carving disc, a card scraper and sandpaper for smoothing
5. As a finish I wiped the wood with CA glue to harden the surface but that was probably stupid

Works pretty well with my guide bushings and didn’t cost a penny.

Good idea! The CA on the wood was a good feature in my estimation. You won’t be as likely to form little steps in the wood if you put down pressure on to center. I guess it would take a plunge router to do that. Nice project, thanks for posting.

BTKS: Thanks for mentioning that this refers to a plunge router. Over here you will hardly find anything else, that’s why I didn’t think of mentioning it. I hope the CA will help. If not it certainly didn’t harm. And the good thing is you can always sand it down and have a fresh new surface :-)

Great idea, think I might try it. I just got a new set off guide bushing for my router and I need a centering pin. Thanks for posting.
