Re: 12" working railroad

Interesting project dozer you have. I have an old Speedcat Dozer that I have to repair. The tracks are worn out, and the spline on the drive sprocket is stripped. I was thinking about getting rubber tracks as well, so I"ll be curious to see how you adapt them to your machine.

Re: Petticoat Junction

Just because it is in Wikipedia, doesn't mean it is correct. Misinformation abounds on the internet.

I'm not saying it isn't the locomotive that was used....

Re: TIG torch electrode

"Thoriated won't ball" I use thoriated all of the time on aluminum and have no problem at all balling it. It doesn't hold the ball as well as other types of tungsten but does work quite well. Granted I have zirconiated on the shelf which is great for aluminum, but sometimes I get lazy....it's not li...

Re: Warped cast iron

If you have enough stock on an edge try a spark test. Hit it with a grinder, short orange sparks and you have cast iron, longer yellow sparks , you have steel. try the spark test against a known piece of cast or steel.

Re: TIG torch electrode

Proper way to weld aluminum on AC is to ball the tungsten. You will get a more stable arc that will hold up better at higher current. Grinding a blunt /rounded end is a lazy way to do it, and I have done it many times myself when feeling lazy. If your tungsten start to get fuzzy little hairs on the ...

Re: TIG torch electrode

You say that you have to regrind the tip when welding aluminum....are you balling the tungsten before you weld the aluminum? Are you welding the aluminum using AC with high frequency on? when you switch over to the steel are you also switching to DC-, high freq on start only? Your electrode size is ...

Re: Piston or Wedge QCTP.

What series is the QCTP? Aloris has a holder for each series that is oversize. I have the CA series on my lathe, which is for 1" tooling, but they do offer holder for 1-1/4". I believe the CXA series is 3/4" but they have a 1" holder as well. As far as wedge versus piston, I have used both and haven...

Re: A Real Dirty Job

Carrdo,

I have been following your work for a while now....very nice indeed! I must add that I am convinced you have a second set of machines that you actually do the work on. Your mill is way to clean....I guess it is for photo purposes only. :D :D :D

Re: Lathe for turning wheels

How are you constructing the ways? Flat bed design, or V? Regardless of the design you would want to start with a ground finish or equivalent on both surfaces. Any surface roughness will chew up the other, whether it's steel , bronze or what have you. The smoother the better. Stay away from aluminum...
