Trying to Quieten the 110KVA Generator

Well my friend did indeed arrive and taking the panel down, cutting the reliefs, and putting it back, as expected was a very quick job - it's now in place to receive the screws just as soon as the 5 mm long series drills turn up.

I've deliberately cut the slots on the large side and the gaps will be filled with expanding foam. I thought it useful to have something that the foam DOESN'T stick to to use less foam and leave a fairer face so I posed the question to Google:

"what doesn't expanding foam stick to?"

And it seems that I asked the same question in 2005 - the answer being 'waxed paper' but the thread I found on RCGroups, which sweeps up threads from Newsgroups was rather sobering as no fewer than four of the contributors to the thread are no longer with us  :bugeye:

A progress report:

I have five panels now in place, four of which are pretty well fixed, the fifth being held by clamps. I tried pulling the second panel into the first using a ratchet strap but frankly it was no better than thumping it with a baulk of timber and a big hammer so I gave that idea up!

I'm again limited by shortage of long series drills - it's taken 10 to get so far  :bugeye: Now admittedly two were my fault, one I dropped the drill, and two I trod on the drill, but the other 8 were in use breakages - mainly on the angle on the floor - there are distinct hard spots in it so goodness knows what went into the pot when it was rolled. Now at 135 mm long they are long wobbly drills, and mostly unsupported as it passes through the insulation but it starts penetrating the angle and suddenly grabs, and it's not just before breakthrough it's in the middle of the web.

Today I took delivery of a pack of 'eaves fillers' and a pack of expanding foam cartridges and a gun to apply them.

. . . more drills on order !!!!!!

awemawson:
I opened up the pack of 'Eaves Filler' and did a trial fit.

I think that it will be OK but may need a bit of squirty foam behind it to secure it in place/

awemawson:
No wonder I couldn't unscrew the collar on the end of the exhaust pipe - the thread has been WELDED  :bang:

Probably have to cut it off somehow, but I still want a bit of thread for the elbow to screw onto  :scratch:

(Pipe extends as far as the chalk mark inside the collar)

Just hi temp loctite...


Maybe you can just grind the beads off and leave the bulk of the pipe?
