Re: Help with throttle valve

I would rebuild what you have. The Allen throttles work well if you put a little work in them. You will need access to a lapping plate and some Timesaver non-embedding lapping compound. The disc and seat both need to be flat. Once they are flat, you need to lap the disc to the seat. You need to put ...

Re: Two Silver Soldering Questions

There is a step between the propane/MAPP gas torches and oxy/acetylene. That is an air/acetylene torch, the old Prestolite or a newer Turbo Torch. People often confuse temperature and heat - oxy/acetylene provides high temperatures but is often too concentrated. When silver brazing(what people call ...

Re: Mogul Kit Differences

Another thing to consider is the boiler. The RRS Mogul has a 7 3/4" OD boiler, while the Allen and Little Engines use an 8 5/8" OD boiler.

Re: Spark arrester design

Glenn, I just checked. My spark arrestor is made from 316 SS woven wire cloth. It is 6 x 6 mesh with .037" wire. The tie-downs are made from 1/16" 316 ss TIG wire, and the band is made from .032" x 3/8" strapping.

Re: Boiler steel source

No - SA 516 is a plate spec. What you want is SA106-B for seamless pipe. 8" pipe is 8 5/8" OD.

Re: Spark arrester design

Glenn, I don't remember what mesh size it is. I bought the material at least 4 years ago. This is the second spark arrestor I've made from a square foot of material. I think it was 4 x 4 mesh. I do know I made the net area through the openings 1 1/2 times the area of the stack. It doesn't seem to re...

Re: Copper boiler water treatment

Mike, can you soften the water? That's the usual first step in water treatment. Then, as Bill S. said, test the boiler water and treat for what you find. Just remember most treatment is aimed at reducing corrosion in a steel boiler. Th pH is usually held between 10 and 11 in a steel boiler. Copper d...

Re: Rapid Syeam Pressure Loss

I would suggest rather than raise the blast nozzle up, lower the petticoat so it is down around the nozzle and leave a gap at the top. This is the way Baldwin and Vulcan set up the front end in oil burners.
Also, open up the blast nozzle.
