I do almost everything on a router table – it’s the only precision tool I have.
A huge amount of woodworking seems, to me, to involve making one edge of a piece of wood at a 90° angle to another edge, so I made (a couple of years ago, in fact), this jig to make me perfect 90s.
The schematic goes …
Basically a baseplate – I use mdf floorboards – thin, fairly strong, parallel edges and, unlike everyone who “scored a bit of walnut burl in the borg yesterday”, is one of the few useful things that ever appears in the bins at my local DIY – great for jigs.
On the baseplate I’ve glued a another piece of MDF at exactly 90°. It took me 2 attempts, but, unless you’re really really close to 90, it’s going to do you no good. (Although, as an aside, I have several very similar jigs at non-90° angles to make the “slight angles” I’m so fond of)
The key is the rectangular slab that’s taken out of the baseplate – this allows you to have your wood protruding into space, yet still be able to run the straight edge of the baseplate against the straight edge of your router fence.
You need a hold down mechanism – I tried those clamps you can attach to jigs, but they were a hassle and they were always wanting to bend my mdf, so, instead, i have any old piece of wood, with 2 bolts coming up and butterfly nuts to hold down. You can have as many holes as you like, depending on the width of your piece, but at any one time you’re only using 2 of them. It’s particularly good for small pieces – once they’re clamped down you are still guiding a big chunky thing rather than a small thing.
This is mine in use edging (on the end grain) a panel of bookmatched jatoba…
Never know – this might be useful to someone.
