I then cut some strips of glass cloth and tacked them into the main section between the pins, then soaked it all in resin and attached the front section and taped it into place. Then I had to smooth the cloth into position blind with my hand up in the nose.

It all came out well when cured though.

Last night I gave it a good going over with coarse wet and dry and a sanding block to remove the high spots and applied a layer of filler, so this is where I am now at. To be continued.

A bit of a job on there Jon. Thanks for the follow on project, good for those who suffer similar fates. You have put thin glass on the outside so after sanding, etc surely it will be slightly wider or is that a very minor issue at a 1mm?

Did Mitch's nose get damaged when he fell? :lol:

Ouch !

The repair looks fairly light I understand there was some Pb in the nose. Just wondered if these aircraft are c of g sensitive and would you plan to rebalance the model statically before flight or "suck it and see"

The cloth on the outside is only there to temporarily reinforce the joints before glassing on the inside, so will mostly be removed when rubbing down afterwards.

Having said that the cloth I used is very thin, much less than 1mm and the outside is uneven anyway after the initial repair as it's impossible to line everything up perfectly. The filler will smooth everything anyway.
