Don't wake a Tiger until you've factored the teeth



Engine ( ASP 25) mounted with GFN mount: the wooden engine bearers are not used to accommodate the tank

Sirji,
I see that you’re doing this test in your kitchen (Don’t think you have a microwave in the workshop)
Hence this tip.
“Do not try to warm epoxy in a microwave after it is mixed.”

But its ok to warm them in separate cupsbefore mixing

Sir pardon my ignorance on this but what is heated epoxy used for

There may be occasions when 5 minute epoxy is too quick and regular Araldite is too thick/ too slow.
And you don’t have the thin Bob Smith 20 min Finish Cure epoxy.

That’s when you have to put some Araldite epoxy in a small plastic cup, and hardener in another small plastic cup, and give them a little time in the microwave (like 10 seconds, not more)

Result - a thinner and quicker setting epoxy.
If you microwave it after mixing, it’ll become a lump before you can use it.
Hope this helps...
Regards

Edit
Rai saheb,
Hope you don’t mind this slight diversion from the main topic...
Regards

Landing Gear installed

Wing mounting arrangement done. Could not use the original because the fuel tank fouls. In fact, because of the tank, I had to change the engine mounting from wooden bearers to a GFN mount, and this had a cascading effect in changes really extending this build

Sir, I rememberreading somewhere in Hanno Prettner’s writing that even that thick fin leading edge has an experimentally found aerodynamic reason, like in the case of the anhedral stab...
