I was going to use al. bronze but switched to deep groove ball bearings.Pontiacguy1 wrote: ↑Fri Mar 15, 2024 7:28 am That's not a bad looking truck sideframe either. What bearings did you use? I assume a radial ball bearing.

Re: Riding car trucks
Cheap and sleazy archbar frame. I originally designed the side frames for water jet cutting... which I lost 24-7 access to when I retired. This frame is laser cut. The journal boxes don't look as clunky when painted black.

Re: Steam Dome Ball Valve Throttle
do you know how much steam will go through a 3/16" ball valve? :shock: it is not a problem.... Nope, not a clue. I don't know what a reduction to a 3/16" hole near the beginning of steam travel does at the cylinders, hence my original post. :wink: Three very kind and appreciated responses...

Re: Steam Dome Ball Valve Throttle
Please correct me if I'm wrong but it appears everyone using a 1/4" ball valve is using a full port version where the port size is around 3/8 of an inch. A regular/reducing port is about 3/16". A 3/16" port seems awfully small. A modified 1/4" 90 degree globe valve looks super si...

Re: Steam Dome Ball Valve Throttle
Thanks for the pics and video Chris. My current thinking is a cam slot in the valve lever and a well supported cam follower on the throttle rod. Or the opposite, cam follower on the valve lever and the cam slot as part of the supported throttle rod. In either case the first travel of throttle pull w...

Steam Dome Ball Valve Throttle
My current and probably last build is an Allen Chloe with a 1-3/8" x 2-1/4 bore and stroke. The boiler is oversized from the prints at 6" instead of 5". Firing will be propane. After a ton of reading and lots of procrastination I've decided to go with a 1/4" ball valve throttle i...

Preferred fittings in a smokebox?
For steam delivery in a 6 inch diameter smokebox do people prefer pipe threads with unions, compression or flared fittings?
Thanks for your input,

Re: Tube rolling max expansion?
Hi Greg, The Airetool tube reduction rolling formula also takes clearance between tube and hole in to account. For the test piece I went by ignorant intuition and feel since my clearance is excessive in that one hole. My test id came out .004 over Airetool's formula result. When I do the actual roll...
