Tools for the Solar powered workshop

After six months of planing how to spend my redundancy money effectively. I have started collecting tools for the Solar powered workshop.

We decided to visit the National Model Engineering & Modelling Exhibition in Harrogate this weekend. We took my two of my youngest Daughters who had a great time looking at all the working Models particularly the tiny working steam engines.

My other half Midge also enjoyed the show with the girls buying all sorts of bits and bobs for her airbrush set-up. The next Model Engineering show will be mid October near Warwick / Lemmington Spa. Well worth a visit. I bought a few small bits and bobs as well.

First Purchase was a Time and Precision Ltd 3 axis x 55mm/2.20inch cubed aluminium positioning stage including stepper motors a steal for £40 with 0.00125 resolution on X & Y at 200 steps or 0.000625 Resolution @ 400 steps. The ideal basis for the baby Bertha project.

Second purchase was a the small Sieg C0 Baby Lathe from Price £165. Thus solving the frustration of trying to use pedestal drill or Afghan lathe etcetera.
