michaelp Posted April 14, 2016 Share Posted April 14, 2016 Hi, I am going to use 'Liquid Gravity' for my wagon kits but was wondering which glue is best for the job. Thanks in advance Michael Link to comment Share on other sites More sharing options...
RMweb Premium newbryford Posted April 14, 2016 RMweb Premium Share Posted April 14, 2016 Not PVA. It can cause expansion issues in the future. as it may react with the lead. I've taken to using cheap (3 bottles from the poundshop) superglue or varnish dripped in. Cheers, Mick Link to comment Share on other sites More sharing options...

Talltim Posted April 14, 2016 Share Posted April 14, 2016 It's also a good idea not to create any completely enclosed airtight spaces . Link to comment Share on other sites More sharing options...
ScRSG Posted April 15, 2016 Share Posted April 15, 2016 I have always used the fibreglass resin to mix in with the weight. Measure the quantity of weight you need to fill the space and then mix the resin and add the weight. The mixture can then be (carefully) fed in to the space. There has never been any expansion issues with this method as far as I can tell. This can also be used in loco boilers etc. If you are loading open wagons with the weight then you can put the weight in the wagon and carefully pour the resin over the weight, it will naturally level and seal in the weight. This can also be done on the underframe of the wagon if the design allows, and obviously the insides of vans before you fix the roof. Use a set of scales or a means of balance to make sure all your stock has the same weight - this will help avoid derailments by some stock being too heavy.

Cheers, Mick I haven't bought any of this 'Liquid Gravity' but I assumed that the main idea of it was that it didn't contain lead? Graham Link to comment Share on other sites More sharing options...

RMweb Premium njee20 Posted April 15, 2016 RMweb Premium Share Posted April 15, 2016 It is indeed meant to be not-lead. Dunno what it is! Link to comment Share on other sites More sharing options...
Rabs Posted April 16, 2016 Share Posted April 16, 2016 It's not expensive enough to have much tungsten in, so it's probably mostly iron. My guess is that it's probably lead free bird shot that's been repackaged for this purpose. Link to comment Share on other sites More sharing options...
NickL2008 Posted April 17, 2016 Share Posted April 17, 2016 Whenever using it, I use all purpose glue such as UHU or Bostick, seems to work as well NL Link to comment Share on other sites More sharing options...
