Has anyone replaced bushings in an aluminum drill jig? No, it's no mine, but I am helping some one fix the one they have. The bushings were checked with a pin vise for play. Some have excessive play; some don't. I believe you can replace the bushings, but before a hammer comes anywhere near that tool, is there another way to remove a bushing from the jig?

The ones that had a head on the bushing were designed for a press fit and I believe the OD of the bushing is smooth... so if you can push it out, you should be able to push another one in. If you have the GB tool you would have to ask him, but I am guessing it is the same, just no head on the bushing.

I've never seen anything with a press fit easily come out. With out some assistance, hydraulic or mechanical.
The SBE has a head on it so you cannot push it straight out.
I would ask one of the machinists here how much or just try to send it back for repair of possible.
But if you are adventurous , look up strongback puller. Probably going to need one made for that size. Maybe hit the bushing with an upside down can of air. Shrink it a little.

Just ask around maybe someone who has the tooling, has done the job before.

I would have to look at the drawing. If it is the GB took he can help I am sure.

Pressing a bushing in would not be the problem. Its getting it out....and getting it out without destroying the tool.
