I'll take a seat here in the corner and watch as well. I purchased the entire series of books a few (ok, more than a few) years ago and never made any of the machines. I did get some ideas when I built my furnace, and made a faceplate for my own lathe (which I have never actually used). I was very leery of the aluminum construction, especially the different expansion rates of the aluminum and steel components. Not to mention just the extreme expansion rate of the aluminum itself. But I'm rather picky when it comes to thousandths.... ok, tenths too... ;) I wish you best of success in the completion of your - !! SQUIRREL !! |

The aluminum parts are rather beefy. For kicks and giggles, I did a bit of a stress test on some of the flashing of one of my other castings and was able to put well over 30 pounds of pull on it. That was all my scale would do. Even at a few thou thick the flashing can hold up to a lot of pounds. I have zero doubt that these machines are likely better than a lot of store bought. My current table saw table is about 1/8" thick aluminum, same with the table on my belt sander and band saw....The Gingery tools are 3/4" thick in places. These machines seem to be brick sh!thouses....'cept shinier and less stinky.... Not sure what you're referring to with expansion rates. The steel ways are mounted with bolts to the aluminum castings. They're never heated together.... Got another pattern made over the weekend, no pics yet. Still have to shellac it. |
