Technical Tips, Builds, and Help / Re: DK Products with stuck/frozen screw

Sounds like you are going about it the right way!

Yes, heat can be your friend at loosing stuck screws, just don't think that a whole lot of heat would be better as it generally isn't. All you are trying to do is make the metal expand and more importantly, then contract again hopefully breaking any hold corrosion has on the threads. Several repeated moderate heating and cooling cycles and a few days of penetrant soaking should bring you the desired results, thus patience will definitely prove to be an important virtue in this situation!

Best of luck with what looks to be a worthwhile project!!!

Technical Tips, Builds, and Help / DK Products with stuck/frozen screw
« Last post by komet163b on June 08, 2026, 12:04:02 pm »
I just received a DK Products steam engine thru Live Auctioneers.

It is built like a tank, but unfortunately the screw in the top of the
upper sightglass fitting is frozen.  Right now I'm using PB Blaster
penetrating fluid to loosen it but I'll need to wait a while before
giving it a try.

Does anyone else have tried-n-true methods for loosening the screw?
Modest heating?  The fitting, silver colored, is non-magnetic so it
probably nickel-plated brass as is the boiler. 
   
I hope it isn't cross-threaded.

Thanks,
Wayne

I like the smoke stack!  Maybe someday you can build a brewery scene featuring the engine.

A few little Lister-D modifications.

Made a brass wire hook for the galvanised bucket.
Stripped the black paint/powder coat of the trolley handles.
Made some hardwood handles.
