Binding Router Jig
I was just about to throw out this cheap LIDL drill alignment jig, when this thought occured:
I turned the handle and carrying assembly upside down, and found that it held the Bosch trimmer perfectly with allen bolt tightening ability. You can see that it can be set up almost square to the bench surface below.
Now I know this is not a binding cutter, but I'm using it to assess trueness.
I can apply manual pressure on the lever to raise the router, and it is forcefully pulled back down by a very tight spring (I could not hold my fingers in the way when re-assembling the thing- it is very strong).
I don't understand how a commercial jig that does this, allows the router to ride up and down freely as the guitar body passes under it?
Does anyone think this is a go-er, once I build the body clamping jig to go with it?
The router should be able to move freely up and down to follow the shape of the back - on my binding jig it moves smoothly on a linear bearing - there are no springs...
More importantly your cutter is UNGUARDED - ....please don't switch it on!
Measure twice, cut once...
Sure - I'm nowhere near switching this jig on!
I see that there's an extra surface to register the body surface on... will keep thinking.
The cutter will always be unguarded with this application no? Ah... i see that it hides within the donut thingy.
I will remove spring and see what the motion feels like.
So here it is
The router moves up and down freely, and there is a riding nub which protects the cutter (here it is at full extension- I had to buy a 1/4" collet extender and build up the router base).
Still need to shape the cradle to allow full access all the way round.
The only issue I can see is that the router has 2mm lateral play due to the re-purposed LIDL drill alignment jig's mechanism, but it is actually solid in the forward / backwards plane.
Did I save £200? Bloody hope so!
