Re: Thieves caught on video stealing mini steam train in West Seattle

Re: coles

I can see your original question has NOT been answered. Oblivion sounds right to me. :shock: The first response answered the question, and you're correct. It was closed, which is akin to oblivion. A loss to the hobby, as was the passing of Anton Bohaboy. H You would think that they would pass the t...

I think I will just tig weld, and build up my cylinders out of steel, like I have done all my others. getting a foundry to pour castings anymore is nothing short of a hassle

You might want to try putting the part on a hot plate and heating the entire thing up. Thick sections can be difficult
