Any empty space in the Dean Goods boiler?


Recommended Posts

I've a new 'favourite' way of adding extra weight where it's apparently not available.

The boilers are round, the slot for motor access is generally narrower than the maximum inner boiler diameter.

I figure out the maximum I can superglue in (careful for holes such as handrail mounts where glue could leak out) and I glue in Pb weighting which can avoid the motor.

Doesn't lead react with glue and expand? Theres a thread on here somewhere with a loco burst apart as a result.


I believe that there is an interaction between lead and PVA glue.

Interesting observation, and thanks for the heads up, if true.

No disrespect but I hope you're wrong.




Yes. He's 100% correct. A very common occurrence and has been covered on here a few times. Some glues will react with the lead, especially PVA and I believe superglue.


Don't touch with a bargepole unless you use something you know won't react.



However some stuff calling itself lead isn't actually lead. ISTR that "Liquid Lead" is now lead free....

I've been using builder's lead sheeting, which I cut to size.

Depending upon the space available, I may fold over, to increase weight within the volume, or not be able.


Totally correct to bring to people's attention any problems encountered.

Looking through the posts, I think what I'm doing is fine - relatively high purity Pb sheet, cut and shaped to size then glued into place.


The problem appears to be when high volumes of adhesive are used, let's say nearly 50:50 ratio of glue to metal.
