In all honesty, the main thing that has put me off rubber in general is all the pre and post faffing that needs to be done; lubrication, removal of lunrication, hanging motors in darkened places under a full moon to reduce (but not remove) the chances of an exploding motor wiping out the whole shebang. I actually found a box of FAI Tan in the loft unused (and never likely to be!). But I digress.....

Well, last night I had a spare half hour whilst young Pippa Blinkette was at Pony Club and Lady Blink had taken car & trailer to Oddbins to stock up, so I had a bash at this here covering malarkey. I covered one of my test frames. I used a single sealing coat of unthinned varnish on the wood, unthinned Balsaloc, mylar, damp tissue floated across water a la Sundancer, and a single coat of unthinned varnish brushed through to attach the tissue. I covered both sides of the test frame, and although possibly not perfect, I am reasonably pleased with the results - especially when dry. I know that this is about the simplest thing in the world to cover, but at least a decent proportion of the Ajax is square!

The weight gain of the test piece due to covering was 0.5 - 0.6g. Allowing for a fair amount of error in weights as low as this on a set of cheap scales, this still gives a projected weight of covering in the low 20s; so lets say c25g. If this proves to be true, this will still enable to total weight to still be close to my upper target of 180g.
