New Visby lathe
Greetings chaps, I was following a thread about Visby lathes and took these pics of my New Visby. This thread was closed so here are the picks. The New Visby was made by Purcell in Sydney there were two versions a short and long bed mie is the short bed. It has a 3 inch bore in the head. I have equipped it with a quick change tool holder which has 8 holders. 3 phase of course and I part own the beastie with my mate Boris. The pics are self explanatory for the most part. Speeds are op to 2000 and are selected by the wheel on top of the head. This gives 4 positions of 3 speeds each. the individual speeds are selected by the 2 handles on the front of the head. It will cut a multitude of thread forms and is at present set for imperial, But looking at the chart there are most conventional threads avalible. There is a number of gears in a cupboard to go with the beastie.

Hi 4-6-4,
Nice machine, well setup with accessories but.. no DRO?
I have the same Dickinson ( or is it Dickson?) QCTP, mine have FmCo stamped on it, from H&F, been looking for a supplier for the tool holders without much luck.. I suspect they are made in Taiwan, but don't know which company.
Regards
Ray

Mick Moyles has some genuine ones but they are *not* cheap. It's cheaper to buy a new 40 position multifix type QCTP IMO.
I've got the baby Dickson QCTP on my Chipmaster. Nice unit but I need a lot more holders. One of these days I'm going to make them as I've got the milling cutters I need to do it. Too many other projects higher in the queue tho.

New Visby
Greetings chaps. I got my QCTP from H&F not cheap but the original was driving me up the wall. I had already acquired a number of holders but no post. So I think I have 8 or nine holders. The mikes go up to 12 inches and there are a lot of sleeves and drills. All accumulated over a number of years in the trade. It is good to see some interest in Aussie machines. Yours 4-6-4

Any idea how old your New Visby is? Looking at the styling I'd guess and say maybe late 60's to early 70's ?

New Visby
Dear Bollie I would recon it must have been top of the line in the late 50,s Mine is still in pretty good nick. The biggest job I have done is 48 drive fit 7/8 Whit bolts for the K to N locomotive conversion at Newport these were .007 thou big in the shank because the drill we used made the hole .005 big. They have to be a drive fit. Talking about bolts the railways used a 1/16 inch taper over 12 inches for bolts they did not want to move. IE bolts that held the cylinders on. The holes were reamed and the bolts were but in until the heads were about an inch from home and then driven home with a large copper sledge. They are a hell of a thing to get out in one piece. R 766 which was gauge converted had to have all the cylinder bolts removed and shortened glad it was not me that was on this job. Yours 4-6-4

Tapered Bolts
Yes Aaron the bolts I talked about were used on Locomotive in places where they were hard to get at when the loco was in service. Cylinder bolts. Drag Beam bolts any thing that was awkward to get at when all the bits were on the frame. As I said it was 1/16 of an inch taper over the length of the shank. The length or diameter of the bolt did not matter. They were driven home and are a real pain to get out unless you can get at them with a sledge. The holes were tapered to suit and the bolt put in until there was about an inch to go and then they were driven home until they were home. The bolts I mentioned for the N Class frame stays were a 2 thou parallel drive fit. When they were done up a socket was placed on the nut and the head of the bolt was struck with a copper hammer while the appropriate pressure was applied to the socket. All fun and games 4-6-4

Aaron, I'm pretty sure the turbine bolts were not tapered (its over 25 years since I worked on a turbine) but they were individually fitted to the holes so both hole and bolt were numbered. From memory I think a special tool that used a porta power set up was used to pull them out and also to pull them back in.
