I have a CNC turning center so holding tolerances is not an issue. If you are interested I could send you a quote. If you want I can quote any alloy of your choice.
Contact me via PM, please.

Re: Source for Wheels & Axles

8 pieces of 5-1/2" rounds of 1" plate (to turn 40" wheels for 1.5"/1.6" scale, will fit in one large USPS flat rate box which is less than $20. You need not limit yourself to the Chicago area in my opinion. True that, and I said as much in my post. As for material, C1045 or C1144 rolled rounds is m...

Source for Wheels & Axles

I am in the process of building up some new Blomberg B trucks and have run into a snag. In the past, I had gotten Diesel-sized wheels (scale 40 inches) from Tom Bee and had a local machine shop who was a client of mine produce axles to my drawings. The machine shop went out of business two years ag...

4) No crud in the new boiler to impair heat transfer into the water. :D
BDD...#4)...maybe so. BUT...with the crud in the old boiler firebox water legs...consider this. There was less water to heat! Carl B.
Yes, but will the locomotive run on hot crud? :D

Re: Electrical wiring in the home shop.

Step drills are the answer when you don't have knockout punches. Having the right tools for the job is part of doing the job. :D As was previously said, creating holes in electrical panels is accomplished with knockout punches. Punches make round and accurately-sized holes, not raggedy ellipses.

Re: 730 Gets a Boiler

Fuel keeps going and going ...Attribute this improvement to several factors: 1) new boiler key hole fire box has greater heating surface area than the old boiler rectangular fire box, 2) number of flues went from qty=21 in the old boiler to qty=28 flues in the new boiler, 3) more thorough and bette...

Re: Mill & Lathe: Where to Put Them?

I read somewhere that it's okay to put more than three #3 wires in 3/4" conduit. The person who wrote that must have a great sense of humor. It's true that you can get three in, if your run is a foot long with no bends. I switched to 1", and now that it's done, I can see that 1.25" was the way to g...

I can see where if you were really aggressive in some steels, it might be beneficial, but for the bulk of what we do, it just makes an unnecessary mess, IMO.
I agree, especially if using a good-quality bi-metal blade (my preferred brand is Lenox).

Re: Dead 3/4 hp motor - starter capacitor?

The wiring was wonky - fixed it and it started right up so cap is fine as well. Now I've got to work on the coolant pump, sigh ... At least I can cut what I need with a spray bottle of coolant if I get desperate. :D Just what it is you plan to cut that requires coolant in a relatively light-weight ...

Re: 12" working railroad

BDD, I'm going to be attaching a tensioner jacking bolt under the hydraulic motors with a locking nut so they can't "walk" in the slots. I suggest you use flange-head capscrews, grade 8, minimum thread engagement of 1/2 inch. The traction motor brackets on my trucks are made from 1/4 inch HR steel....

Re: Dead 3/4 hp motor - starter capacitor?

I've had a 13" Jet Horizontal band saw for years - bought second hand from a guy who definitely did stuff to the wiring. However it has worked for me for years until today when it is totally dead. The motor is a 4 pole, 3/4 hp. There is power to the box that has wires split off to the motor switch,...

Re: 12" working railroad

I did a little work tonight getting the hydraulic motors fit into their brackets, took some measurements so I can weld them onto the truck cross tubes and have them centered inside the body. I actually made these brackets long before I ordered the hydraulic motors, so I'm happy everything fit well....
