Been using the Shop Smith drum sander to make wheels, train boilers and on and on, so thought I would make it have a fine adjustment to more easily get it set up right.
The sander on the SS has a great depth stop but it’s on the wrong side of the tool when using the tool in horizontal mod.
What I’ve been doing is getting the stop to get a wheel sanded close then would unlock the table and tap it with my hand to get just a tad closer , which works fine but I have no real idea how far I’ve taped it so that’s why the new jig.
I was out scrounging 6 months ago and found a box full of old wood working parts router fences and parts of miter fence clamps some really cool stuff to have around to make jigs.
So going to use the fine tuning fence ability of a router fence to make my jig.
It will pay to just show you the jig all put together first, will save a lot a confusion and you can see what I’m up to.
1- Made a base with runners to keep the base from being pusher back.
2- Bolted the router fence to the base. It came with long rods but I shortened them.
3- Made a second base to connect to the front of the router fence it has two sides[with tongues cut in them] that are nailed to the main base.
4- The center of this second base has grooves to fit in the tongues so the center can slide down the middle.
5- Took my regular tire holding jig and screwed it to this second base. by it being screwed down like this I can easily change it out,
6- I now drilled a hole down the center of one of the sides so I could add a bolt to secure the main base to the saw table.
Here’s the bolt with a handle to lock it to the table.
I can now use it just like before but can now lossen two wing nuts on the router fence and slowly screw it in or out very slowly for super fine adjustment to the wheels.
No more taping the table and wondering if it moved.
You may have also noticed that the dust shield box I made now moves with the sanding disk which will keep the opening smaller so more dust gets sucked into the cyclone.
This project could also be done with some turn buckles like those used on screen doors I would think.
Hope this give some of you ideas for your own jigs.
That’s all focks.
