Time to make the side grip plates, finding sheets of plastic is a bit hard so I came up with a trick to make some.
First grab a piece of pvc pipe, cut it to the right length and then cut a slot down one side
Next heat the pipe for a few minutes, you know when it is heated enough as you can see the pipe distort.
Open out, don't use fingers to do this as it is hot
Then flatten between two pieces of wood and hold down until it's cooled
The you have your flat plastic, draw your piece to shape
There you go, side cover grips cut, just have to make the grooves, going to try heating a small strip of metal ten pushing into the plastic to leav an impression. If this doesn't work I will just cut slots with the dremmel
