Rear stay rough carve.

 
So having trimmed off some bulk material, it was time to do some carving. I attached a rough grit car paint grinder to my angle grinder and set to work. It worked a treat. Fast and suprisingly accurate. I wouldnt use it for anything fine, but as a tool for getting the shape fleshed out it is marvelous.

Getting the symetry to work on this has been a challenge. The parts do not have to be identical in shape, but the points at which they meet the frame and the wheel drop outs do need to be very acurate. So the stay arms will be a little organic in shape, but the wheel will (all being well) sit true to the main frame.

Trimming.

Having bonded the 5 layers of each rear stay it was time to start the shaping process. However I needed to get rid of lots of material in some places, so instead of hacking at them with files and rasps, I set about them with a wood saw.

Cutting rear stays down to size.
 
Nesxt step is to actually do some broad stroke shaping. I am going to give the angle grinder a go fitted with a car body paint stripping grit disc. Should be interesting.
