Router Bush size

[Adrian80]

Hi All,

Im a going to mitre a work top and my cheapo macalister router comes withe a bush, but i am fairly sure its 29mm. Can't find my vernier gauge.

The jig needs a 30mm bush, i am going to have problems, or do i just need to slip 1mm packers under the jig mounts? or just leave it?


Any advice greatly appreciated.

Put the bush in the slot and see if it rattles, smooth fit will mean it's OK.

hi tried this, ther is quite a bit of space in the slot, i think a 30mm bush would also rattle around.

I think i might practice on a bit of ply and see what happens.

If using a jig should not need a tight fit since you are pushing the tool towards the cutting edge, the cut will be mirrored by the mitre, you can't take off too much, only too little by making loose passes.

So hopefully, it should all work fine, after all its only 0.5mm difference on the cutting edge, might just need to reduce my cut and mark line from 8.5 to 8.0 mm


Thanks
