and a D1-8 drive plate like this one, but bigger -- for the un-initiated - the D1-8 is the camlock system to lock it to the spindle nose on the headstock - this size is hen's teeth to find and are not cheap - ever

managed to save 200 quid on the package, delivered - happy enough with that ........... and got to meet a hell of a nice guy driving the seven an' a half tonner who delivered it - his wife's a niece of a friend of mine - small world
as an example of what this stuff costs ....

was gonna bang the new four jaw on the Harrison yesterday ... can't even recall why ATM - after the session I've had

pulled these off the pallet when they arrived and stashed 'em away - had given 'em a quick look over, but cursory really as looked fine/as per seller's pix
anyway - grunted the 4 jaw out from one box to another and am stood thinking HTF am I gonna get that up on the lathe's bed and onto the camlock, when it suddenly struck me -- camlock pins and centres looked way too small

- as did the drive plate's

....
checked the face plate - yep full inch pins - t'others were 7/8" which're D1-6 camlocks and smaller PCD - Harrison's a D1-8 ---
Oh bollaux thinks I - HTF did I miss that unpacking them.
came down the house and checked the invoice and listings - deffo D1-8 was what I bought so ... got on to Ben Richardson who runs the outfit they came from (big s/h tooling sellers)
"
You're kidding - someone's gonna be getting a slapped wrist Monday - that is an elementary mistake - especially as there was the D1-8 faceplate in the same package - don't panic, we have a couple more 4 jaws on the shelf in D1-8 and a back plate - we'll get them swapped ASAP -- send me a couple of pix to wave under the packers nose on Monday please - anything else you got your eye on ? Can get it all on one pallet "

Funny you should say that - was looking at your listings last night and there're a few bits I'm fancying, if we can have a deal .......... "
Any way .. turns out the 4 jaws in stock are 400s not 300s - which I have no objection to - they didn't have any when I bought the 300 and I have a nice 4 jaw Pratt Bernerd steel chuck, which I wanted the mount for, that I acquired from Cheltenham last year, on my
round robin shopping expedition, when I picked up those 6 ft forks & carriage and dividing head
so today I thought I'd better check to make sure the face plate went on the Harrison's spindle nose .. wrestled the 3 jaw off onto a board across the bed-ways
and cleaned the nose and cam lock holes with some air -
gave the whole machine a good blow over, while I was at it then grunted the face plate up onto a.n.other board -
having checked it'd clear the bed-ways with the gap still in - it did - just

getting said plate from there onto the nose was - er - epic - it's as heavy as it looks
sadly it didn't end there ----- I had it back off and on several times -- Apparently Ben uses 'students' for laccies, for cleaning tooling, etc., pre-listing/sale ... whatever muppet'd been at this, he'd not matched the camlock pins back to where they came from

... perm 6 in any configuration your like ... took me a good hour an' a half this afters, to get them all to seat to the line .. so's the cams'd lock them in the prescribed travel range
the line should be
just visible - most were a lot more than visible
so when the cam pulls them in it locks between the arrows -- now you see it ......................................... now you don't - which'll lock the plate/chuck to the nose -- took some bloody juggling on every one and had to swap a few around a few times
got there in the end, but if the muppets had just done them one out/back in, at a time, etc., there wouldn't have been an issue

... but it's still sat on there this evening
had the three jaw out on the bench - stripped it and gave it a good blast out with 150psi, then re-lubed it as it went back together, then as it wasn't tea time yet, dragged the 4 jaw out for a strip, clean, blast out, lube and re-assembly
and a suss of what I need to do to fit a new D1-8 mount to the back end of it - will need a good polish up, first -- think I may need to get that dividing head cleaned an' ready for action shortly - getting them 3 holes in the right places on the drive plate will be fun !!
cleaned, oiled and ready to get stashed -- 's about my limit, ATM for getting on/off the bench/floor


........ and I'm out of pix - again
