I know we don't really do build threads here on the UK section of TRF , so this isn't one.. nevertheless, I've been working with Stafford based company Easy Composites' improved XCR CF skinning kit, and Im very pleased with the results, so I thought Id post up some pictures by way of recommendation. For this build Ive been wrapping 3 PML phenolic tubing with one layer of 2/2 3K twill. The materials are relatively easy to work with, particularly given that the resins are very low odour. I bought the larger 1.5 x 1m roll of the 2/2 3K twill, and bought the 1kg can of top coat, although the 500g base coat bottle was needed. Suffice to say I didnt use up the entire amount of either. Skinning is the simplest form of lay up, involving allowing the initial base coat to go to tack, then applying the cloth, then successive layers of top coat, which have to added at specific (and varied) points during the curing process, so you need to make sure you set aside sufficient time. It also involves progressive flatting, which is pretty laborious. The first few flatting sessions 120 400 grit are dry sanding (professional masks and goggles essential) and then after that, and the final layer of top coat, its wet sanding from 400 1200. However, the results are very pleasing. The instructions are very detailed and easy to follow, and theres also videos on the company website. They also run a very helpful technical advice line staffed by a very helpful actual real person. With careful measuring beforehand the seam can be kept straight and flat, and there were very few pin holes.
The only point of departure I made from the instructions was the very last stage, where I didnt use the NW1 polishing compound (not sure why youd name a polishing compound after Camden Towns postcode but there you go..). Once Id finished wet sanding with 1200 grit I masked off and sprayed the roll pattern (a can of Fiat Red-Orange from Halfords), lightly sanded that once it was dry, then glossed it all with two coats of clear lacquer.
The fins are 3mm ply sandwiched with the same CF, set in fin pocket dams. The thrust plate was made from 3 rings of laser cut ply, clamped and glued, then drilled for metric threaded inserts to hold the flanged retainer.
I hope to scratch, scuff or otherwise ruin all this fancy finish at this year's Big Ears...
