How to repair Tiger Moth engine mount?
Flying about an hour before sunset tonight, I lost my Tiger in the sun and when I could see it again and work out which direction it was going I flew it into a power line. It nosed in from about 20' and broke the engine mount stick clean off at the firewall.
Any ideas how to repair this? I'm thinking I might drill about 1/2" into each piece and join them with a 1" long piece of carbon rod that I have. However not sure how to get the correct alignment if I do that , try my luck I guess.
Anyone have any alternative suggestions?
thank you all for your responses. I had more time to research this problem via the search engine today and marvelled at the variety of approaches taken; from the 'CA/epoxy the broken bits together 'approach to the elegantly engineered approach of Jeff/Doppler.
In the end I adopted a quick and effective fix; I drilled a small hole approx. 1/2" into both the firewall stub piece and the engine mount piece, then cut a 1" piece of 0.055 piano wire that I had left over from making a slightly beefier undercarriage. I then epoxied the stick back together using the wire piece as a 'dowel joiner'. The slight flexibilty of the wire afforded me a chance to slightly increase the thrust line angle, as the model turned left as originally built. Of course this robust fix means that I'll probably just bend the prop shaft next time, as I doubt it will break at the same place agin! Thanks again.
