Re: Stretch Husky in a weekend

Are you using flux core wire without gas in your wire welder? Or are you using solid with a flux gas like Argon? I ask because your welds, no offense, kind of look like what happened when I ran out of fluxed wire and did not realize the new spool was solid! It was dirty and lumpy and very bright; th...

Re: Riding Rail Kits

Iron Pony was started by Mike and Joe Devlin on Anaheim CA. I know Mike. They sold it off to Canadian Rod Johnston, who changed the name to "Riding Rail Kits", and ran it for a while. Eventually he abandoned it and just let it die...

Re: Wendy suspension vs. 'normal' springing.

My 7-1/2" gauge Narrow Gauge Porter by Don Young has a no springs at all. The rear axle is solid to the frame, the front pivots on a crosswise rocker beam; 3 points determine a plane. Many were built this way.

Re: will spring steel mill?

I have also read where some Live Steamers have found that a full spring pack of reasonable scale is far too stiff. One common solution is to make some, perhaps alternate, spring leaves out of a plastic strip such as Delrin or Nylon. Both are readily available in black, some are also available graphi...

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

Oh, and always try to tap in the mill or drillpress, avoid "freehand" tapping. When it starts crooked, it is more likely to jam and break. I made set of small guide blocks (on the lathe from round bars about 1' diameter or so) to guide the tap straight for better freehand tapping off the machine. Ju...

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

I love RET's 4-5-40 and 6-8-10-32 trick. BLOODY BRILLIANT! Another thing; an experienced machinist once told me that he avoids using 6-32 screws like the plague, he pointed out with the 10,8, and 6-32 all sharing the same depth of thread, the center "core" on a 6-32 is exceedingly fragile and those ...

Re: will spring steel mill?

I recall reading some expert (maybe Don Young, Greely or LBSC Lawrence) that said you can get away with hard strips with soft ends. He softened them by sticking them through a potato, leaving just the end to be annealed. He then torch heated them red and done. They could now be worked with HS Steel ...

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

I found it really helpful to lay out a plan of exactly what I was going to do tonight, while I ate my lunch at work. Something like, "3-jaw outside, cut 2 pieces 1'' steel bar 4" long, center drill, 1/4" drill, turn to size, turn end for end, repeat on bar #2, part off 4 bushings, deburr, paint blac...

Re: Boiler stays and heat expansion

Prototype boilers also feature flexible stays in addition to rigid stays. They account for the differential expansion, which may be transient; the problem is mostly in warm up and cool down, I think. I suppose they could all be flexible, but rigid stays are far less complex and therefore considerabl...

Re: Car stability paper

At the OCME, our conductors sit back to back with the engineer. That way they can make eye contact with the riders and watch for straying feet, but sides are a great idea. I also learned the phrase "Levante los pios!" for our Spanish-speaking riders.
