On the LeBlond, the entire top bed slides, so you never lose contact. You also can't get near the chuck, depending on how far the bed is retracted.


Yeah I have run one and seen a few other brands also. Ditto the thoughts on it. A picture of one for those who have never saw one.

I'll never understand why they had the LeBlond at Sperry. The large diameter feature was used for turning bulkheads for the missile---short, but large in diameter. A gap was needed, but it could have been a fixed gap. Anyway, it was one hell of a machine. It would take, in stride, monster depths of cut in chrome moly. The example in point was the chrome moly forgings for the axles for the launcher.

Ahhh! Sweet memories of my youth!

I single pointed a 316 SS 3" X 2 pitch LH Acme thread on one. It was nice to adjust the length of the bed for the part length. Made a few large pipe bending dies for Albina pipe on it to. As well as a lot of tube sheets. It really shined boring and sleeving motor end bells for spun bearings in large electric motors. They could be done so much faster on a smaller slide bed than a regular 42" swing lathe. Since it was easier to see and reach what you were doing. Ditto the cuts you could make in all materials to.

Hi Everybody,
Here is my contribution to this thread. Its a 1956 Colchester Chipmaster I have rebuilt and modified> I have added a tee slotted cross slide and a new topslide of my own design plus a rack operated tailstock. The motor has been replaced and operated via an inverter. http://s107.photobucket.com/albums/m287 ... 5-04-4.jpg

I have also designed and built this lathe

mostly on the Chipmaster

Amazing!

What do you do with your spare time? :lol:

Welcome to the forum. Very impressive work you've done.

jackary,

Those are some fine machines and videos. One question among many; in the end mill flutes sharpening, how do you coordinate the advance of the wheel to the degree of the spiral and the length of the flute? I hope I asked that question properly. :lol: Another question. Is the relief for the flutes a result of using the proper diameter wheel or is there a second step in the sharpening process? Please excuse my ignorance in the process of sharpening end mills. :oops: :wink: :lol:

Jack.

I just measured the amount of twist in the endmill and the length of the flutes and put this in the computer. The wheel was set by eye to give an edge with the angle guessed at by setting the wheel arc at a suitable height. Not really scientific but it worked.

my ancient drummond round bed, this picture was taken from ebay when I brought it for £50 a few years ago now, it has a base now and a new chuck. It currently sits in my work area until I can save enough money for a workshop at home.
It has come in useful for various things at work and I have used it for bigger work than it was ever intended for.

What a nifty oldster. What swing is it? My brother-in-law had a similar Drummond just like it with cast iron legs incorporating the treadle and flywheel.
It became motorised before I ever saw it and was the first metal lathe I ever used. NEAT, thanks!

4" swing and about 11" between centers. I believe these could be purchased with the treadle too.

Actually if anyone could shed some light on the object next to the three jaw chuck I would be interested. I have used it to make a crude milling slide but would still like to know what it was meant to be.

Nothing special but I'm excited, so I thought I'd show my new lathe. It's a 12" x 36" King

Nice! RS, how come the DRO isn't lit up?
The x,y feed selector level looks a lot like my ole 12x36. Is it just up for cross and down for long. or do you have to pull the lever out or something, to get the cross feed?
Reason I ask is that some times, when I come to the end of a long. cut, if I flip the lever up too enthusiastically it'll start cross feeding. That can lead to some blue air in the shop.
Enjoy your new machine, it sure looks well finished.

Thanks Stevec, Flip the lever up for "X" (longditudinal feed) and down for "Z" (Cross feed). I wondered about the accidental engaging myself but when I tried to make it happen it wouldn't due to two metal blocks in the middle that forces to you pull the lever or right to the left to get around them.

Good, that's what I had hoped you're machine would have.
I, on the other hand, have not yet gotten around to installing some kind of safety device. I wonder how many more crashes I'll need to git'r'done.
