Why use drill rod at all ?....mild steel is just fine
Not if you expect the axle to also be a bearing surface.

Re: What type of Drill Rod for Axles?

My go-to material for axles is C1144 TGP (turned, ground and polished), sometimes referred to as Stressproof®. The material is reasonably easy to machine, has good strength-hardness properties and has a bearing-quality finish. An alternative if C1144 TGP isn't available is C1045 TGP.

Re: Language on the forum

.... Not everything said or spouted from the mouths of men require me to form a response. Sometimes silence says more than 10,000 words! Dave C. Good point!

Re: VERTICAL TURRETT LATHE (CNC)? NO WAY

Saw one of those vertical turret lathes in the Boston Naval Shipyard in the 1960s while our ship was in for a refit. The faceplate was big enough in diameter to set a dinner table for six, with room left over for the waiter. American industrial might at its finest!

Plain and simple---none of those products have the ability to reduce rust to native iron. All they do is provide lubrication, to lower friction.
Where I do find WD-40 useful is as a tapping lubricant for aluminum. :D

Re: PB Blaster is Snake Oil

Seems like it's eternal thread...I apologize for bumping... I believe that PB Blaster is the best available PENETRANT.I first found it about 3 years ago and it is all that I use now. It uses capillary action to "follow" threads on a stuck object such as spark plugs,pipes,nuts/bolts,hub caps etc.It ...

Also anyone experiment with using longer sections of rail, say 20-40ft sections instead of ten foot?
At the ILS, we have some sections that are 20 feet.

The shop has 12’ ceilings and is about 30’ x 20’ . The structure was originally built as a two bay shop for R...

Re: Train Mountain Track Building update

Steel rail could mean more wear on train wheels. Have you thought about this as a possibility? I hear this at regular intervals and would like to see this myth put to rest. Aluminum oxide is highly abrasive and in fact, is one of the most commonly-used industrial abrasives. Anyone who makes the fir...

Re: WTB Clippard MJQC-B4B4

Straight air brakes are pretty much direct acting when using an air reservoir to store pressure. Pretty much. None of our trains is long enough to see significant brake pipe propagation time, which is about 1.1 milliseconds per foot in standard atmospheric conditions (20° C at sea level). Restricti...

Re: WTB Clippard MJQC-B4B4

The MJ's are jumbo sized quick connectors...While the QC's do present a restriction in the air line (like most quick connectors), if you're sticking with the 1/4" OD x 1/8" ID...don't think that restriction is going to be noticeable for our train operations...not unless you're running a 200+ foot l...
