RMweb Gold Mikkel Posted June 19, 2019 Author RMweb Gold Share Posted June 19, 2019 On 11/06/2019 at 21:09, Mikkel said: I have been monitoring a particular wagon for some years and will post a photo of the current condition when I'm back home. Just to follow up on that: I built a wagon in December 2014. For weight, I used Deluxe Models Liquid Gravity, and their Rocket Card glue for fixing it in place (as recommended by them). In January 2017, we discussed whether the method could cause expansion over the longer term, or lead balls dropping off. So I took this photo: At the time I wrote: Quote "Some of the balls appear loose in the photo, but when poking at them with a scalpel they are firmly fixed. It seems there is some cracking - which could be a little worrying for the longer term? - but so far everything seems to be stuck well in place." Now, in June 2019 it looks like this: There is no change since the last photo that I can see. The wagon is now 4½ years old. Will continue to monitor it. 4 1 7 Link to post Share on other sites More sharing options...

Not sure about enclosed spaces though, e.g. loco boilers - that's a different kettle I think (ha!). But when can we ever be sure? Do glues ever "stabilise"? Which leads to broader questions: How long do we expect a model to last? A lifetime? More? 3 Link to post Share on other sites More sharing options...

RMweb Gold Popular Post Mikkel Posted June 23, 2019 Author RMweb Gold Popular Post Share Posted June 23, 2019 (edited) Had an interesting correspondence with Oxford Rail. I asked if they had any plans to do a Dean Goods with a roundtopped firebox, and they sent me these CADs. Only joking It is of course my rebuilt Dean Goods, now in primer. Archer's rivets next.

RMweb Gold Donw Posted June 24, 2019 RMweb Gold Share Posted June 24, 2019 The problems with lead arose from the PVA glue which is mildly acidic and so reacted with the lead. I never had any trouble with lead pieces araldited into wagons. Just a thought lead in a brass boiler would be subject to electrical corrosion if there is a suitable electrolyte in contact with them PVA could do the job.

Guest Jack Benson Posted June 24, 2019 Share Posted June 24, 2019 Mikkel, A few ago, I stopped using lead sheet and switched to self-adhesive plated Ferrous weights. They are not particulary suitable for odd spaces and are a swine to cut to shape, but they have not corroded or reacted with the model. cheers Jack Link to post Share on other sites More sharing options...

MikeOxon Posted June 24, 2019 Share Posted June 24, 2019 Anyone tried using tungsten powder, as sold for adjusting the weight of golf clubs? See, for example, https://golfcomponentsdirect.com/product/dynacraft-golf-club-tungsten-powder-8-ounces/ It's claimed to be 50% more dense than lead powder, although rather expensive.

Buhar Posted June 25, 2019 Share Posted June 25, 2019 I was wondering about old, used tungsten tool bits. I think they're tungsten carbide so I don't know if that affects the density. 1 Link to post Share on other sites More sharing options...

Simond Posted June 25, 2019 Share Posted June 25, 2019 Try lead shot in a sleeve made from finger bandage. Or mixed with plasticene Or epoxy or fibreglass resin, or casting resin Without PVA there is no issue with lead, and it's reasonably cheap & easily available atb Simon 1 1 4 Link to post Share on other sites More sharing options...

Martin S-C Posted June 25, 2019 Share Posted June 25, 2019 Please keep us posted on the Dean goods build Mikkel, its looking fantastic. Also, I'm seriously envious. Wish I had a non-Belpaire version. They were much more attractive in that guise. 1 Link to post Share on other sites More sharing options...
