Re: Key stock for axles and drivers?

Glenn: On my speeder I use a key and spacer that sounds like what you are looking at. And I can change spacers to change guage. But, my axle is threaded on the end with a locknut. The axle is still a tight fit and I have to use a puller to get the wheels off. Now, that being said, the nut looks ok o...

Re: Which steam pump would you build?

The only builders notes I could find are in the zip file for the 1/16 pump. There are two word files in that folder, one labeled 1/16 notes and the other just labeled duplex pump notes... looks like that may be for both sizes... I haven't perused it just yet tho. No word doc in the 1/8 zip file. Thx...

Re: Which steam pump would you build?

Bill: Guess I'm blind or something. When I use your link provided early in this thread, it sends me to a page where i can select the two subsequent pages , one labeled "pump files", one labeled "misc item designs" and there is a shortcut to email you. Then I selected "pump files", where it gives me ...

Re: Which steam pump would you build?

Bill: I have the castings and I have downloaded your plans dated 2008, for the Large BvB pump (actually downloaded several years ago) and haven't had the nerve to start working on it up until now (maybe). I am not a machinist but I do a little on a lathe and mill as needed and learn one function at ...

Re: Feed water pump best practices

Glenn: On your second question. I assume that you mean...where is the best place for the return line (which originates from the discharge of the pump) to be plumbed to. If that is the case, on some of our closed systems in the hydrocarbon industry, any "relief valve" discharge (which is what you are...

You can see, if the weir shape does not fit the crucible, glass can eek around it. Not the end of the world, so far it floats and pops up out the vent & on top the sprue.
With a two person pouring shank, this requires a 3rd body.

Re: Alloy of brass and zink in a home foundry

The way we found that seemed to work the best is pretty simple. BTW, we are amatuers not pros. The glass is broken up clear glass from an apple cider jug. Pieces range from about 3/8" to 1" Using a #16 crucible, we put in about 1/2 cup of glass. The resulting layer is very thin. I suppose we could m...

Re: Alloy of brass and zink in a home foundry

When our fire started it was as we mistakenly added bronze swarf to the crucible of molten bronze (Open flame furnace). I don't think it was a case of 'distillation fumes', it appeared that as the swarf passed down thru the hot gasses at the opening of the furnace, some of it must have ignited. The ...

Re: Alloy of brass and zink in a home foundry

Thanks for the hints.
We have had a "zinc fire". When we learned of the glass, we used it in the next melts... works great.
