Tap Extractor. They come in sets and are also sold separately by size. Go slow and easy. Work both out and in a little at a time. Use plenty of cutting oil. If you break the fingers, you can purchase new fingers. The extractors come in 3 and 4 flute types but you can not use them interchangeably. Fa...

Jos, I agree with you. His explanation only covers about half of the subject. The other half being the "petticoat" or eductor portion of the system. While it is important to design/control the pressures/flows through the nozzle sitting in the smoke box. It is equally important to design th...

In my area, they refer to it as "flame spray". That might or might not get you to information.

Good Luck

Take a look at wood stove circulation fans. They run off peltier modules, the heat from the wood burner, and the heat sink allowing one side to remain cool so as to have the chip generate electricity. They run a small DC motor to turn a fan blade. The hotter the stove, the faster the fan spins. You ...

I have a couple of issues needing to be brought up. First: REMEMBER you have water in your siphon tube when storing you locomotive in cold weather. You may find you need a new siphon tube come spring time. Second: The reason for a minimum of 20% and preferably 50% maximum gauge pressure over normal ...

Take a look at Crescent Nicholson #06992N 10" Double/Single cut Bastard file Safe Face back. It is a triangular knife edge file. They make a 4" #06711N, 6" #06804N, 8" #06898N, and 12" #07085N. I have seen these used on plastic laminate edges. A file card cleans the plastic ...

Glenn,

I have to agree with Mike as I have 8, 10, and 12 lb rail profiles and that one is thinner than the 10 lb I have. With that skinny web, I wonder how much weight it could safely handle?

Good Luck.

Are you thinking of Berryman B-12 Chemtool? I remember using that dunk type of carb. cleaner. Don't know if it's still available in the dunk tank type but there are other B-12 products still on the market.

Good Luck

Glenn, Concrete ties would have a slight capacity advantage, I believe. The difference would not be worth the time and effort to calculate the modulus of elasticity per size and concrete strength. AND all of that is beyond my abilities. That's where Doug VanVeelan would have been the man to go to. M...

On good solid ground/ballast, 4x4 ties on 20" centers, minimum axle center to center 20". Maximum single wheel load is 2520lb. per rail - 5040lb. per axle. Same parameters using 4x6 ties 6" side up. Maximum single wheel load is 2880lb. per rail - 5760lb. per axle. IF the 4" side ...

Hi Glenn, The quoted figures are for a WHEEL POINT LOAD on any size tie. I can figure out, accurately, the load on different size ties IF it is desired or needed. Actually, a 4x4 and a 4x6 can be able to handle the same load depending on HOW the tie is oriented. A 4x6 "standing UP" with th...

Gentlemen, Just a quick note to provide a bit of assurance. Using 12lb. rail in good to new condition with tie spacing at 20" center to center, the safe POINT load is 2016lb./wheel/rail. Thus, each tie/2 rails/2 wheels are capable of bearing 4,032lbs. The same calculation for 8lb. rail yields 1...
