Lathe building questions . . .
Ok so I have this strange idea swimming around in my head, that haunts half
my waking hours and will probably steal some of my resting hours too, building a Gingery lathe. But I don't have the book so I'm going off pictures mostly. So I've got a lot of design (drawing) work ahead, and probably plenty of trial and error...but it allows me to make wide changes... for instance, I was thinking, I could save on cross-slide length (and flex as well) by offsetting the spindle to the rear side... why haven't I seen this before?

I suggest you lie down for awhile until this idea passes, Tim. Then think
about spending several hundred hours making something that will be *marginally* useful at best. You'd be better off panhandling for several hundred hours and buying a real lathe with the money.

Look more closely at the various photos, it's already offset. In fact, http://www.gizmology.net/gingerylathe.htm shows this quite clearly. The biggest single modification I have heard people mention is switching the bed casting from that used in the lathe plans to one much more similar to the mill plans, where instead of just 4 bolts holding the CRS bedways onto a relatively thin 1/4" casting, like http://www.backyardmetalcasting.com/lathe1.html you use a 3/8 to 1/2" thick casting around the priphery with a few cross braces and fasten the ways down with two rows of screws, about 10 or more. For the mill bed see http://www.backyardmetalcasting.com/guest_bruce.html in the 2nd to last photo it is the L-shaped piece, about halfway up the right side, though you wouldn't make it L-shaped for the lathe, just straight. Have you looked in http://groups.yahoo.com/group/gingery_machines at a bunch of the other ideas people have tried (and often discarded)? --Glenn Lyford |

7... Look more closely at the various photos, it's already offset. In fact, http://www.gizmology.net/gingerylathe.htm shows this quite clearly. Huh, never noticed it before actually! you use a 3/8 to 1/2" thick casting around the priphery with a few cross braces and fasten the ways down with two rows of screws, about 10 or more. Yup. I'm already thinking about how to stiffen it...if you put a flat bottom on it, or at least diagonal (or triangular truss style) bracing, that would help a lot. I wonder if I made the pattern (or used one in stock if they already have one) and brought it to a commercial iron foundry... Have you looked in http://groups.yahoo.com/group/gingery_machines at a bunch of the other ideas people have tried (and often discarded)? No... tried registering with Yahoo once but it took too long and I forgot what it was...

Ok, I can see that a little reading might do you a lot of good. HOwever, and remembering the sand fiasco, (Tuan has it), do you think by some strange happening you might be able to find the Beloit airport at about maybe 2 in the afternoon, saturday? I _might_ be able to find my way out there with the aforementioned books so you _might_ get an idea of the magnitude of the project you're considering. IF you go for it, more power to you, if you don't, at least you'll have an idea of what's involved. |

om... do you think by some strange happening you might be able to find the Beloit airport at about maybe 2 in the afternoon, saturday? I don't see a problem.. not too far a ride!

I don't see a problem.. not too far a ride! Ok, game plan. I'll be on my way from here at about one, which should put me there just before two. The books are yours, should you decide to do anything with them, or to pass on to someone else, but only after you've read them. Gingery books are wonderful for showing how complex operations can be done with simple machinery. His techniques are basic, and his methods sometimes seem primative, but they work as they should. The value in his machines is not the machine itself, but what would be learned in making them. OR, in other words, if you're not going to do it, find another sucker to infect with the disease. ;^)) See you at two. I'm driving an older S-10 with no paint on the roof. |

You'd be better off panhandling for several hundred hours and buying a real lathe with the money. Grant is right. Do your best to save up and keep an eye out for lathes at sales and auctions. keep the foundry for making stock and projects. Got any birthdays coming up?? Note that my opinion is worth almost as much as you paid for it! Mark Rand RTFM |
