Again I want to thank everyone who took the time to share their knowledge with me. I have come to the conclusion that TIG is what I am looking for. LOL I haven't hear it called heliarc in many years. Thanks, that brought back memories.

I have checked out these welders. I believe they are the new Norstar welders. They look pretty good. Thanks.

I know you are right Brian, but there are other factors here. Since I will be looking for show quality finishes I expect that I will have to dress the welds and maybe even use some filler before painting. Also, I would like to have only one welder, if possible, and would like to be able to weld...

Thank you for taking the time to post such a detailed reply obviously based on your experience. It looks like the Lincoln SP175 has been replaced by the SP180. I'm checking that now. My plans are to build 1/4 scale rc cars powered by home built engines. A 1932 Ford coupe looks like my first...

Thank you all for the great information. This looks like one of those instances where if I try to get in cheap I will end up spending more in the long run than if I just did it right from the start. My next question would be what is the least I can spend to get a good tig welder? Not including...

Quarter scale is 1"=4". I would like to weld car chassis and steering and suspension components in this scale. Tiger is not in my budget. But, I can afford to start with a flux core machine and move up to mig. I don't expect tight quality welds, but can I get close?

Thanks for your input. My intention is to move from flux to mig, but in the meantime flux will have to do.,

I would like to be able to do some welding of mild steel. Sizes of parts in the quarter scale size. Is it possible to learn to weld and produce clean, neat welds with a flux wire welder under $500? If so are there any machines that stand out, or you might recommend?

My years of milling machine experience have taught me that a mill spindle needs reverse, something the RF-30 does not have. I use reverse for power tapping and running left hand tools. Left hand drills are great for removing broken screws. They often grab and back the screw right out. So I...

This what the RF-30 looked like when I got it into the shop. It had been stored in an unheated and un-insulated shed here in CT for several years. It was complete except for the top cover. All of the handles had been removed when it was moved into the shed and were in a box. The spindle would...

Mine is a model B.

Thanks John. These screws will not work on the RF 30 because the wall thickness at this point is only about 3/16". This doesn't allow for a locking setscrew. I used a 5mm socket head cap screw cut to length and filed 2 flats on the end. This way you have the head to tighten against the spindle...

It turns out that the threads for the pin in my RF-30 spindle are 5mm x 0.8. I drilled out the original screw that was too long preventing the collet from seating all the way into the spindle. Then I re-tapped the hole and used a 5mm x 0.8 socket head cap screw cut to approximately 0.270" long...

While cleaning up the recently purchased used RF-30 I discovered an R-8 collet would not go in past the pin. I got a telescoping gage up into the bore above the drive pin and the bore checked at 0.950". The collet tolerance is 0.9490" to 0.9495". So I concluded that the drive pin stuck out too...

I photographed these engines at a local business show. They are in a 6' scale model boat built buy a man here in Manchester, CT. The builder of the boat is not the man who made the engines. The boat builder told me that the engine maker was having problems with the camshafts. Have you ever seen...

Thank you very much for your help. The photos have been posted and it was rather easy after your clear explanation.

The bench that my old South Bend came on was never solid enough no matter how much bracing I put on it. Recently I bought a used RF-30 and I needed a spot for it in the shop. When I got the mill a new bench for the lathe was well under way. I wanted the 2 machines next to each other so I decided...

Thank you for your help. I have my pics in Photobucket and can get a picture in a post. I can get text above a pic but not below it. And the next photo I insert will only insert before the previous pic. How can I control the order of pictures and get text between them. Hope I am not too much of...
