The Home Machinist!

At one time you could purchase #4 frogs from Cannonball Ltd.. But they have pretty much shutdown. RMI shows them but they are machined steel and are pricy. Or you can make one our of rail. I will get a picture of one at Ridge Live Steamers.

For a 50’ radius into a Wye switch I would use a #4 frog.

Viton shines when it comes to chemical and heat resistance. It's also got a good mechanical strength. But, it's not as flexible as Silicone, especially at lower temperatures, and it can be more expensive.

Hi All

Due to a family member’s health the paperwork for the Winter Meet has not been sent out. We are working to resolve this.

Any vendors that plan to attend can contact me.

Please remember that a reamed hole is not round and will most likely be oversized. Invest in some laps. They are not expressive.

I have been grinding the crank pins for the Mikado using a Dumore tool post grinder.

I think I called the Throttle valve type by the wrong name. Here is the drawing for the valve. Can it be scaled and work?

Tim

I have started to drill holes in the main crank pin. There are two for cotter pins to hold the nuts from coming loose. I still have to drill the grease cross holes.

Hi John

I was so fixed on machining the axle first I did not think of doing it in a different order. I already have the axles machined to length and center/grease hole drilled with a 60 degree center at each end.

Tim

I drilled 3/8" holes through the axles as per the prototype and will bolt the square blocks to the ends so I can quarter the keyways in the axles. I am using the standard right hand lead.

Hi All

When identifying parts what was the standard practice?
