Thread: Micro adjuster for Triton router fence

I've figured out how to avoid all that winding. Mark 2 coming up soon.

An interesting jig.

I am guessing you use the router a lot as hand held router and the need for finer adjustment on the fence has been required. Well done on coming up with a solution for the need.

OK, here's Mark 2.
With the two knobs and 2 bolts loosened the fence assembly is free to move in or out along the rods for the initial coarse adjustment. You then lock the two bolts, which fixes the rear horizontal aluminium bar. Fine adjustment in/out then takes place via the red thumbwheel - one complete turn delivers about 1mm of movement. When everything is in place you tighten the black knobs to lock the fence.
I plan to replace the two bolts with plastic knobs as soon as they arrive.


BTW, if you click on the pictures they should zoom.

Nice work. Where did you purchase the thumb wheels from??
Thanks

I had them left over from the old clamping system for a router on the RTA300 - there's a picture of them here:

I've just been searching the web for thumb wheels for another project, and they are amazingly difficult to find.

Have you tried Carbatec?

Yes, they don't sell them.

I found out that the thumbwheel was too difficult to move in the original position. I have rearranged things and it now works like a charm. I can supply details if required.

Details would be appreciated - thanks

Very clever sir....thank you for sharing....

As requested, some more details.
With both the small and large knobs loosened, the wooden crosspiece attached to the fence is free to move along the threaded rods, to give the coarse positioning. The following two pictures show the extent of the travel, which is about 80mm. In the closest position the wooden cross piece is up against the router base, while in the furthest position the fence is a little further out than it could be with its normal fixing.

Fence furthest from router.jpg
If I had not evolved the design in stages I might not have put the deep slot in the cross piece, but it now allows me to maximise this travel, because the nuts holding the thumbwheel screw in place are able to be placed in the slot, rather than on the outside of the wood, where one of them would lessen the travel in the furthest out position. Since the thumbwheel no longer lives in the slot, it does not need to be as deep as it is.

As the close-up shows, I have placed washers inside the slot, and then tightened a couple of nuts. If I were doing it again I might make the slot a bit narrower and use one nyloc locknut rather than two nuts.
The end of the machine screw rides in the left hand hole in the wood. The aluminium cross piece is threaded to take the M6 thumbwheel screw. Tightening the small knobs (they are plastic screws to prevent damage to the adjustment rods, but on reflection this wouldn't matter, because the threads are not used down this end) fixes the aluminium cross piece to the router via the threaded rods. Moving the thumbwheel in or out then moves the wooden cross piece and the attached fence relative to the router. When all is in the desired position tighten the large knobs to stop any further movement.

BTW, I know one of my picture tiles is mis-spelled, but I tried replacing it but the website insisted on retaining the earlier version, even though I had deleted it!!
