Seedy Al Posted January 24, 2018 Share Posted January 24, 2018 Sure they do. If you wanna make everything melted and fucked. Though back in my day of classic car services, the panel beater there would repair Austin Healey shrouds (alloy) with a gas torch. Then we got a tig lol. But he was fuckin good. Cast is a different situation all together. Just jb weld in there mate Quote Link to comment Share on other sites More sharing options...

It sounds like there is a very very fine line between fixed and fucked 1 Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted January 24, 2018 Share Posted January 24, 2018 Yeah with out a doubt. He tried to explain you need to look for when the metal starts getting glossy. Because the next step is bye bye. 1 Quote Link to comment Share on other sites More sharing options...
JasonK Posted January 24, 2018 Share Posted January 24, 2018 for a gauge with heating aluminium you can set your gas torch to a real sooty flame and put a bit of the carbon over the aluminium to be heated and then go about heating it with your normal flame untill you start to burn the carbon off, at that point its hot enough 7 Quote Link to comment Share on other sites More sharing options...

SOHC Posted January 24, 2018 Share Posted January 24, 2018 I got some of those alloy repair rods from trademe, they work very well with the oxyacetylene, its a cross between soldering and brazing, you can join alloy and copper together as well.

tortron Posted January 25, 2018 Share Posted January 25, 2018 In the old days they used to bolt stuff inside the combustion chamber of flatheads to increase power Really it just increased pre-ignition, but it's proof of concept that you could just screw a plate into the head and increase compression that way. You should probably shape it to increase flow tho. That's more important than compression for a flathead *Oh it's an ld28 Same diff. Better off increasing the piston height imo. Get long rods or weld up the piston tbh Quote Link to comment Share on other sites More sharing options...

chasinthemirage Posted January 25, 2018 Share Posted January 25, 2018 Anyone got any tips for removing PVA glue from timber? I'm hoping that I can remove the tracks from my train set without stuffing them as someone has secured them with copious amounts of glue.

chasinthemirage Posted January 26, 2018 Share Posted January 26, 2018 I'll give that a go, internet reckons solvent would work but I'm concerned it might melt the plastic track sleepers. Quote Link to comment Share on other sites More sharing options...
