It is in a lot better order then mine... Mined is pretty much stuffed as far as precision work goes....

Seen a couple of those sold on that Gray's online site..

That looks great, bigger than what i thought it was going to be hahah
The one on ebay is tiny compared to yours and Boris haha cheers for pics 4-6-4

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.

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 ?

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

sounds like a nightmare. there is always bolts you don't want to come loose. Couldn't they just of checked them for tightness occasionally ? how often would these bolts be removed?

Its probably more for alignment purposes than making sure they don't come loose.
Fitted bolts are used in lots of different applications. eg Steam turbine coupling bolts are all fitted and numbered.

Philip "Metalman" kindly mailed to me an original DICKSON toolpost and ancillary equipment brochure dated 1984. I will scan and post it tomorrow.
When I read Visby I thought of Clisby, certainly not something with a three inch bore!
Nice lathe 4-6-4.

hi bollie are they tapered shank bolts? are they numbered for balancing?

4 6 4 the bolts you are talking about are they tapered shanks like a tapered pin?
thanks aaron

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.
