E-poxy use for firewall
Hi
I had an accident yesterday. Ran out of fuel and dead sticked...realised it to late (couldn't hear my engine, friend of mine was starting his next to me - not his fault though) and was on a long low pass and way too slow when I realised the engine is not running anymore. I couldn't turn the plane around for none of the runways...it stalled and just before it hit I got the nose up. It hit on a slope, which probably safed it from most damage. The landing gear bent - easy to fix. The cowl got a hit here and there - already fixed. The firewall also broke out, this was also a place which was repaired previously and it broke on the joints which was glued - so a kind of a clean break it was. Now I want to know, would epoxy hold the firewall efficiently? The firewall takes a lot of strain when he engine is running WOT right?
What I did so far was to clean up where it broke, I put A LOT of epoxy on it and glued it back into place. I did however see that it's not a 100% fit (possible gaps between the firewall and sidewalls here and there), so I also put some more epoxy inbetween any joints and held the plane nose pointing up so that epoxy could flow backwards into any gaps which might still be there.
I then pulled on the firewall where the engine will be putting strain on it...I used quite a bit of force and it held. Did this a couple of times and nothing moved. I was thinking today however about gluing four pieces of plywood (long strips) on each joint where the sidewall and firewall comes together for extra support. I'm not too worried about weight. Before the repair I had +- 80grams of lead infront which could be taken out if neccessary.
Would Epoxy do the trick or is there actually something else I should have used?
