Boy and Girls, This blog is to supplement a project I penned earlier, regarding Lathe disk sander with micro adjustment. Please click on the link to read about the micro adjustment feature of the brains behind the underlying mechanism. Just a quick memory twister….
This table was designed using Sketchup and here is a link to it for anyone interested. Again I have not provided measurement as everything depends on the person undertaking the build and their respective timber and hardware availability. Just as a rough comparison, the table is 300mm x 350mm and the track is 400mm long (too lazy to shorten it and aluminium swarf is a bugger to clean up). If you want to use my measurements, simply download Sketchup Make (freebie) and use the tape measure. Here is a link to a quick start I wrote for anyone not familiar with SU (be warned… there are many more out there much better).
I have cut a lot of parts using a lazer (because I can and it’s an easy transition from SU to the lazer table), however, most are straight cuts and can easily be performed using standard cutting tools and a router. In either case these pictures are just to get anyone interested, started.
The 19mm x 19mm “runner” is designed to provide an anchor for the 2 way vise’s jaws and greater meat for the t-track’s screws.
The jig needed a front support to brace the work against the rotation of the disc. I curved it to minimise contact as I sneaked the whole contraption up to the sander and it also served as a zero clearance to stop “burring”. It will eventually wear back and need replacing. Made out of the same thickness (6mm MDF) as the “sled”.
The supports were made out of 2 pieces of 3mm MDF, for no other reason than to automatically provide a slot for the t-bolt’s head. 6mm dowels were used to align the strategically lazer cut holes for glue up alignment.
The movable “sled” was designed to mount a 5/16” dia. bored wheel at one end and a 1/4” dia. at the other, locked in by a t-bolt.
The “sled” is braced by 2×5/16” dowel at each end, that was the same width as the t-track opening.
Spare supports were made to cater for differing requirements. The curved support had to be cut right back to facilitate small circles like wheel’s rims (min 34mm dia.) or use a strip of narrow MDF clamped to the table as required.
The jig in use giving a small shave to a MDF stunt double of a construction vehicles’ wheel.
Thank for taking the time to get this far.
