Thread: Hamatu Lathe

I saw that tailstock one a while back on PM, nice idea. Add that one and RC's compound power feed, and you have a full power feed lathe on all axis's.

I didn't hear from the crane mob today and we're heading into a 4 day long weekend in Rocky so nothings going to happen transport wise until next week. No problem really asI need to clear some space.

I was a little suprised to see that the lathe wasn't bolted down. It has 6 adjustment bolts resting on steel plates about 100 x 50 mm.The plates are recessed to maintain their position under the bolts. Certainly seems easier than grouting threaded rod into the concrete floor. I guess with enough weight its not going to move around much.

Just make sure they don't try to pick it up by the spindle...

Ideally they are picked up like this

Now that is a great way to move a heavy machine.

I have been considering how to sling this machine. There doesn't appear to be any designated lifting points. I haven't tracked down a manual to see what the manufacturer recommended so I will probably sling under the bed being careful with the lead screw. There does look to be a lot of weight in the headstock so i will procede with caution.

I've never seen this on a lathe before.

Okuma used that arrangement around the same time.

As for slinging it I would be surprised if it does not have bar holes, my Mazak which is 7 years older has them.

Thanks for the tip. I'll check this out next week.

I've finally got the Hamatu home.

Crossfeed was right. There was provision for a bar to be fitted through the lathe to aid with slinging.

It was a tight fit into the shed. but professionals with the right equipment made it look easy.

The cincinnati mill was another disposal item at TAFE awaiting collection (not by me).

Next step is a good cleanup and try to sort out some power for the beast. Unfortunately I have been unable to find a manual but the search continues.

Well done John
The pictures of them swinging in the breeze are always good.....

That Cinci looks like one hell of a big mill, any idea of how much it went for?

Hope your making chips soon!

I admit I was a little nervous when they lifted it on and off the truck.

The cincinnati no2 mill was listed as fair condition. I believe there was some electrical issues. Not sure who got it or what the cost was.

With my current space restrictions I resisted the temptation to submit a tender for it.

John

Looks like a good lift, the bar through the bed looked a bit undersized but was obviously up to the task..

Bar size was 35mm mild steel. Couldn't have gone much bigger.
The crane driver told me of a time he lifted a lathe where the bar shattered, nearly piercing the windscreen with a piece of shrapnel.

Miserable weather in Rocky this morning

I thought it was nice "stay in bed with the electric blanket on" type of day... ..... Supposed to be rain tomorrow...
