I do hope this is the right place to post this. It is one giant 'tool' in my toy workshop that I actually use a lot.
I measured (sort of!) where I wanted to run some track on my workbench (a converted freezer with layers of MDF, pine and ply and finally melamine for a top).
Being a cheapskate, I thought I would see how much use I got to decide whether or not to 'upgrade' to real t-track. I actually have quite a few metres of t track but I'm too cheap to 'waste' it on this project.
I firstly made a deep groove with a router bit, in a few stages. I then did the final routing using a t-cutter router bit. 'Precutting' most of the work before using the t-cutter allows for less strain on the bit.
Anyhoo, I made up a few hold-down thingies that slip and tighten into any of the slots and basically keep my work steady and my hands free for more important tasks.
Like holding my coffee cup
I intend to add a light/lamp holder that can clamp too, as well as a few other doodads - moving support tower for my dremel tool or my VDO camera, or...
I need more hours in the day.
