Re: Need some speed tips for getting a project done faster.

A good piece of advice I've been told is figure out when to be a brain surgeon and when to be a blacksmith. Not every part needs to be to a +/- 0.001 tolerance. Its taken me a while to break myself of wanting to be super precise on everything, but it does make a difference. Like most of the cosmetic...

Re: Super Scale Cylinder Cock Valve

I dont know of one off the shelf, but I think one of the AMES ball valves could be modified to work like an air tool shut off valve which should work just fine for operating cylinder cocks. With the ball in the on position, drill a hole through the body into the passage of the ball. Then rotate the ...

Re: Urgently Help needed concerning J 611

Sounds like the May trips they have scheduled are fundraisers to fund more maintenance for 611.

Re: Building the 2.5" Scale Shay

I'm pleased to hear that your Quick Weld worked. Yea! Remember to have fun re-timing the eccentrics. And Thanks to Pontiacguy1 for the added knowledge for LocTite pre-cleaning. Folks on this Board Rock! ~RN I did have fun, timing stephensons valve gear can be an interesting thought experiment. And ...

Re: Building the 2.5" Scale Shay

Also consider using a modern wicking super-glue to secure the shafts. Perhaps green LocTite? I'm sure there are better products than the Green L. Just make sure to flush out all oils prior to application, perhaps using brake cleaner. Other ideas? ~RN Im a little dubious of using loctite on the cran...

Re: Building the 2.5" Scale Shay

I’m definitely going to hang on to this info!
My machine is good for 180 amps so it sounds like I should give the crankshaft a quick burst of 180 amp to tack it in good. Doesn’t need to be a super strong weld but I don’t want to have to fix the crank a third time

Re: Building the 2.5" Scale Shay

It is a bit tricky, you have to run the small cup and then really dive in and hit the power. Wrap a soaking wet rag around the crank with only the weld area exposed. Make your first tack, then jump 180* across and hit it again as quick as possible. Change the wet rag out for another one and cool th...

Re: Building the 2.5" Scale Shay

Do you have access to a TIG welder? I wouldn't be afraid of using it to put a few fusion tacks on that crank to keep things from moving again, if so. I do have a TIG welder here. I’ve tried that approach once before though and wound up pulling the shaft out of square with the crank web. Maybe I was...

Re: Building the 2.5" Scale Shay


Here's a video of the engine on air. Running nicely two notches back from the corner and about 300 rpm, this equates to a track speed of around 3 mph.
Now to decide on the next part to make, so many options still

Re: Building the 2.5" Scale Shay

Two steps forward, one step back. Got everything running and was doing a shake down run of the engine. Low and behold one of the press joints of the crankshaft came loose again, I must really not be good at press tolerances.... Used Bruce’s trick of cold chiseling the shaft to make it a tighter fit ...

Re: Behemoth engines

Fred, thats an Ikon Engineering Shay (link has been corrected) . It is 3.75" scale. I believe they still make them, but they are in New Zealand so shipping would be expensive on top of how ever much they want to build the shay. I dont know of any 3.75" scale shay kits out there, the few shays that s...

Re: Building the 2.5" Scale Shay

Properly designed and manufactured split friction bearings are supposed to work without frequent re-greasing. The lubricant used is important. A thin film of grease (or oil) keeps friction at bay. For axle bearings, the upper bearing radius should be slightly larger than the axle, "squeezing" the l...
