Fillets and JB-Weld and stuff....

Post  ejparrott on Thu 20 Feb 2014, 7:14 pm

Question principally for the likes of Lynn, Tim and Brian who've been steaming their engines a bit in the last 12 months.....

I've got a fabrication for the engine I'm building at the moment and I want to add fillets in the corners to make it resemble the casting it should be. Has JB-Weld been successful where it's been used on the T rings of the front and rear wheels? A little doubt crept into my mind about it having nothing to hold it in position in the corners and whether it might work loose with running, thought an experienced view would be worth asking for.

Cheers!

No problem with my isopod p whatever.

There is quite a good key if it is squeezed on. The gap between the ring and hoop.

You could put a couple small holes in the surface to act as secondary fixings. Also there should be very little flexing to work it loose on your "casting".

I used car body filler on my wheels and everything is still present and intact even with the state of some of the local roads I have been running on, can't say the same for my back though!!!!!

Thanks guys, I'll look in to both then, but by the sounds of it either will be ok. To be honest, I'm probably wasting my time, its a stretcher between the frames behind the smokebox, and quite likely you'll never notice the fillets once the boiler and saddle tank is on! They'll only be about 1/8" rad max, but I'll know they're there!

Finally finished the job!



What an effort that was...ended up having to 'profile' the rads with a burr - made a lot of a mess!
