You say that you are using a CNC machine. I am assuming it is a mill. You could just lay it in the vise with the cylinder horizontal along the X-axis. Using an endmill of the appropriate diameter, program a g02 or g03, give the Y and Z coordinates with the J and K coordinates and cut your...

If you want to build an electric furnace, check out Dan's Workshop Blog. Specifically, the page about his electric furnace. I think I first saw it on the Backyard Metalcasting forum. He sells plans for it on his site for $3.95US. I thought enough of it that I actually bought the plans. I haven't...

As another hobbyist with a history of seizures, I'll add my two cents worth. You'll obviously be the safest if you stay out of the shop for a while. Failing that, only work with supervision. Also, whatever your doctors told you about driving should also be applied to machining. With all that...

Lindsay has retired. Check their site. They have several links to other dealers that may have some books. Also, check Amazon, Barnes and Noble and E-bay for used copies. http://www.lindsaybks.com/ Jon

I've rebuilt my bottle jack a couple of times. I even put a page about it on my site. See the link below. I found o-rings on the plumbing aisle at Lowe's. They are probably not for use with oil but they work and they were cheaper than a new jack. Besides, I hate to have something broken sitting...

Talk to Keith at Turnwright Machine in Cape Cod. I stumbled onto his Youtube channel a few weeks ago. He gets a lot of interesting jobs in his shop. I'll post links to his website and youtube channel below. http://www.youtube.com/user/kef791?feature=results_main...

I made one several years ago after seeing it in Digital Machinist magazine. I made the mount to fit in my indicator base as well as a drill chuck and 3/8" and 1/2" collets. I never was successful at getting it truly centered but I did find other uses for it. I now use it for recording machining...

With the Choremaster finished, I am trying to get back into the Snow. I have a lot of partially finished parts. This is a "family portrait" of what I have so far. Settle in for a LONG ride. Thanks, Jon

Awesome job. Thanks for taking us along for the ride. Will you be bringing this one to Denton this summer? I'd love to see it next to its big brother. Thanks, Jon

It is amazing what sound can do. Thanks for the link. I just found these a few minutes ago. It has nothing to do with fire but is impressive none the less. http://laughingsquid.com/sound-shapes-sand-in-beautiful-demonstrations-of-sound-visualization/ Jon

This has nothing to do with model building, but I thought it may be of interest, anyway. For the past month, I have been trying to revive my uncle's little tractor. It is a Lodge and Shipley model 8 and is powered by a Clinton model C1100 Choremaster engine. Everything about it is very worn out...

That is amazing. Reminds me of the tiny jewels George Luhrs builds. See his page at the link below. It seems like one would need a microscope to see some of those parts. http://www.minimodelengines.com/ Jon

Thanks for all the info. Fortunately NOS parts look like they are more plentiful than I had previously thought. Hopefully there will be no need to try to build up worn parts. Looks like all I'll need to do is turn some bushings and maybe valve tappets. I'll probably get the block bored next...

Thanks guys. In talking to a friend at the small engine parts place, he found a Briggs piston that should work. The size is right but it may have to have the wrist pin relocated. There's no way to know without seeing it. The shop that will bore the block can also deal with that. Pete, I keep...

I'm going to drag this topic out of the archives. I have a question I hope Rick can answer. I have a very worn out Clinton engine that my uncle wants rebuilt. The problem is that the bore is oversize and out of round enough to warrant an overbore. The piston is worn undersize and the top ring...

If all you are concerned about is file size, then convert them to MPEG's. The files are much smaller and upload a lot faster. I use this converter. It's free so I can't complain about the price. http://www.avitompeg.net/ Jon

I also have a Lincoln similar to the one Chuck has. Mine is a PRO-MIG 125. It runs on 110 volts on a 20 amp circuit. I have never tripped the welder's overload although I have tripped the house breaker a few times (operator error). I use the self-shielded wire so there is no need for shielding...

Is anyone going to the Southeast Old Thresher's Reunion? I am probably going July 1. It is mainly old farming and industrial machinery but I did see a few models there last year. http://www.farmpark.com/ Jon

Hi My name is Jon. I live in western NC. I have been making big pieces of metal smaller for several years. I originally started machining with the idea that after I got a little experience, I would build model engines. Along the way, I got sidetracked restoring old small engines. After bringing...
