flyingbrick Posted January 26, 2018 Share Posted January 26, 2018 depends if it said "waterproof" on the bottle. I think some have aliphatic resins or something that make it waterproof Quote Link to comment Share on other sites More sharing options...

UTERUS Posted January 26, 2018 Share Posted January 26, 2018 Hot water /steam will soften pva to make it release. Quote Link to comment Share on other sites More sharing options...

Yowzer Posted January 26, 2018 Share Posted January 26, 2018 The subject was welding combustion chambers. Hence the question, would you trust it in a combustion chamber. Whether or not you mentioned it is irrelevant when it was in response to the topic at hand. 1 Quote Link to comment Share on other sites More sharing options...
Yowzer Posted January 26, 2018 Share Posted January 26, 2018 Ignoring all that, it was a legitimate question. I've never used the stuff, I have no idea what it's like. Would you trust it in a combustion chamber? 1 Quote Link to comment Share on other sites More sharing options...

Would you trust it in a combustion chamber? probably not, its about $10 a rod and if you over heat it with the torch and it turns black the whole lot will go bad Quote Link to comment Share on other sites More sharing options...

Was thinking of welding up the combustion chambers of a spare L26 head to bump up the compression. Factory is 8.8:1 and I want 10:1. Skimming it won't yield the results I want. See if you can get some 4943 alloy filler rod. Its better than most for alloy heads. Or get some flat top pistons? Quote Link to comment Share on other sites More sharing options...
chasinthemirage Posted January 26, 2018 Share Posted January 26, 2018 I think some PVA is water soluble but I have no idea what sort they've used when they built the track. The issue with using anything that vibrates or levers up the track is that it tends to snap the tiny tabs off that hold the track onto the sleeper and once the tab is gone it's stuffed. Only 9mm between the rails to give some idea of the size of the tabs. I'll try some steam/warm water if I get time this weekend. 1 Quote Link to comment Share on other sites More sharing options...
chasinthemirage Posted January 26, 2018 Share Posted January 26, 2018 I can't deny that I'm tempted to just buy some new track, I've got probably 15-20m to clean up. Quote Link to comment Share on other sites More sharing options...
chasinthemirage Posted January 26, 2018 Share Posted January 26, 2018 Varies somewhat depending on brand and quality but there's been a few bulk lots on trademe pretty cheap, last lot I saw was $70 for about 10m worth of flexible track.

Bling Posted January 26, 2018 Share Posted January 26, 2018 Set fire to the set, then pick out the railway iron from the smoldering mess, 3D print 4000 new sleeps and slide them on. Job done. But in all seriousness, even if you get the track off the deck, you'll probably spend hours tidying up the sleepers. Could always pull the iron out, then remove the sleepers as they should flex upwards, then reassemble by sliding the iron back in. What guage is it? Was some barry selling some train stuff at ric market the other week, can't recall if there was track too, but he had a box full of rolling stock.

chasinthemirage Posted January 28, 2018 Share Posted January 28, 2018 I had a go with the warm water and some lightly glued bits came away just fine and others broke. Probably isn't going to be worth the effort really. It's N gauge, nice and small. Quote Link to comment Share on other sites More sharing options...
