Router Lift Redesign


I've redesigned and rebuilt my vice-held benchtop router table to use an old scissor-jack for the lift, rather than the big bolt I had coming up from below (that's what's sitting on the platen in this photo). I've kept most of the old frame and just added some bits to increase the height enough to cater to the jack.

The scissor-jack is superior to the base screw in that there's little or no lateral pressure on the frame while the router is being raised or lowered, so there's less need for lateral bracing. I will probably add some anyway, just to make the whole assembly a bit sturdier, but there's not really any great need for it.

I cut down an 8mm screw-eye to use with an electric drill to turn the jack-screw, but I have no need to be raising or lowering the router that quickly, and it's a bit of a faff hooking up the drill every time I want to change the height. Besides, I'd need to do the final adjustment manually in any case, for accuracy.

So instead, I've just mounted the old hand-wheel to the jack's hook-tab with a couple of small steel brackets. I can raise or lower the router to its full extent with just six or eight turns, and maintain very fine control over the bit height as well. I've done a little bit of testing, and the screw doesn't seem to shift at all under vibration from the router as it runs; if it ever does, I guess I'll have to rig some kind of clamp to the hand-wheel, which shouldn't be difficult.

All in all, I'm very pleased with the way it's turned out. It all looks a bit shonky, but it works well. Now I should replace the MDF top plate with a nice slippy piece of laminate, or maybe even a sheet of stainless steel.
