Re: Seeking curly spoke a 4 hole industrial-style wheels

Look at the flywheel offerings of Martin Model and Pattern. There might be something there you can use.

Re: Some experiments with Cubify Design

I'm more than halfway through a build on the 1 1/2" pump. I'd say the hard part is the steam head and all the drilled passage ways. I already spoiled one attempt due to a bad casting. Got to make a new casting tomorrow since I'd like to finish it up by Saturday night. Anyway, I can't see any use in ...

Re: David Rose

David had a locomotive that he imported from the UK. I forget all of the details, but it was sold at that auction to Bob Cohen, a member of GGLS. Bob still has it, but hasn't run it in a number of years. I believe it was red but forget the wheel arrangement - maybe an 0-6-0T?

Re: Entry Level Casting.

We have certainly got off the subject of 'entry level casting' using simple oilsand type moulding, but it's been very interesting nonetheless. Probably most of what can be said about simple casting has been said and the rest is probably up to me to put it into practice (which I have been trying to ...

Re: Entry Level Casting.

Harold, shell molding doesn't require wax patterns, no burnout, etc. Shell molding is where you drop a resin bound sand mix on a heated aluminum pattern, jolt it, then roll it over to empty off the uncured sand. Then the shell is removed. Two shells are placed together either in a frame backed by sa...

Re: Silicone Molding Compound

I would use Castaldo LTV. It is a vulcanizing rubber. Although it is heat cured, the heat is less than the 3d plastic output from my printrbot. That is, the heat required isn't enough to deform ABS.

Re: Starting In Lost Wax/Investment Casting "Degassing"

Degassing Silicone I poured my fist mold today. Can you use to much vacuum when degassing silicon? My chamber will pull 29". Tim Remember that when you lower the air pressure, you also lower the boiling point of the material in the vacuum. I have sucked 29" in my dessicater with RTV in it and got f...

Re: gunmetal?

I just checked on gunmetal formulas listed on my Beyer-Peacock drawings. Looks like the G1 type is used for cylinders and such - 88 Cu, 2 Zn, 10 Sn, and the 85 Cu, 5 Sn, 5 Zn, 5 Pb for a lot of the mechanical things. These two alloys would be pretty easy to make. If you can already melt bronze, then...

Re: Electric/Diesel Loco Identity

I just found an ID plate and it's "Little Engines - Durango." It was probably bought (new) around 1998-2000. Does anyone have a catalogue sheet or any other paper for this engine? I checked LE catalog #300 (no date) and it is not listed. This is a cat from Durango. LE was bought by John Braun from ...

Re: Possible new 3.75" project for some; eye candy for all.

3.75 would be too big to manage. I'm building one in 2.5 and it's already 11 1/2 feet long about. Nice engine. I have all the factory plans for the engines too, NGG11 to NGG16. Easy enough to scale, but rather hard to decide how to execute certain aspects. So, I'm calling mine a free lance Garratt. ...

Re: looking for cast iron tubing

You might check with Alro and see if they have a rem or drop. There usual length for durabar is 6'. It will cost a fortune, probably. I've used some durabar tubing but years ago. It is nice to machine.
