Royal Engineers

Served with the Royal Engineers from 1970 - 1974, after training got posted to 31 Workshop Regiment in Longmarsten near Stratford-Upon Avon and from there to 31 Armoured Engineer Squadron in Osnabruck Germany.

The "badges" and "flags" are not the original squadron designs, they are my own designs for own use.

Hung up router for the time being.

As we are moving to another house in a few weeks I've taken my CNC to pieces and "hung up" my router for the time being. When we have settled in to our new home, space permitting, I will build a bigger and better one, hopefully. When  I do, I will do a new write up of how I build it from scratch to finish including photos. The old one did work quite good with a few modifications but eventually the screws  used to hold it all together started to loosen and the whole thing became a bit wobbly.

I learned a lot using the old one and have realized where I made design mistakes that could easily be modified and made much better. On my next one I intent to use nuts and bolts to join the woodwork together which will make it more sturdy and should last a lot longer. One of the things that really bugged me was the "wobble" in the moving X-table. I've already experimented using four sliders on the old CNC using two under the "bed" and two on the sides seems to have eliminated most of the wobble. But because I had to do it in a hurry before I took it apart, I didn't line up the sliders perfectly so the "bed" did not move as smoothly as it needed and put a lot of strain the stepper motor couplers braking two in the process. I intend to experiment more using 4 sliders as soon as we have settled in in our new home. Using more expensive sliders that don't wobble as much as the cheaper version should give me better results.

It may take a while till I build me a new CNC but I will build another one, even if it's only a small one for PCB making.
