Hi Jeremy
What is a suitable coupling for 500 revs/second? :confused:
Balance probably isn't a prime consideration, but no bending parts obviously.
I'd probably go for a rod though one shaft engaging a pair of driving dogs on the other, then spend half an hour adjusting it 'till it ran quiet :D

Looking at a mill on ebay today, idly threw in a £500 bid and matched first place.
Then the bidder I was tied with withdrew his bid :confused:
Then he bid £490 :confused:
Hello, thought I, he's playing mind games. So I upped my bid to £750 so now he hasn't got a clue where I am :rolleyes:
It's going to go for a lot more than that so this is all rather academic. I doubt I will get my new mill until this recession really starts to bite :D
bet you were getting worried... but in the end it went for a very reasonable £2,260 (but was £1500 with <1min to go).
Picked up a good set of engineers parallels 10 pairs x1/8" for £15 on eBay, a bargain I think.
Have decided to buy MT3 collets and a few other bits... (6" vice, some endmills, etc.), priced up from RDG they come to just over £250... any suggestions where else to check pricing?

P:S If you buy from RDG regularly you'll have a nice collection of rulers :D :beer:
Already priced up on Chronos, they are a lot more expensive. I think it is because they include postage in each item's price and that adds up when you buy a lot at one go. And I already have 2 RDG 6" rulers!
Here's my shopping list - what should I add/leave off/change?
11-piece MT3 collet set (need to check drawbar size)
MT3 indexable face mill (need to check drawbar size)
MT3 keyless 1-16mm chuck (1/2" BSW drawbar)
12-piece set of metric end & ball mills
centre drill set
Vertex K6 milling vice
metric tap and die set
1 - 10mm in .1mm HSS drill set
Thats £362 (I added a couple of things!)
Re: What Collet Chuck have I got?
I was only slightly dubious because I web searched it and found two interesting thoughts. Some bod in Yankland saying an early 80's refurbed MH-600P was worth about $1500 so my bid was about right. Someone else saying his had crashed and the only thing coming on was the hydraulic motor.
Hydraulic motor :confused:
Also I'm changing units up on the industrial estate. My landlord has plans to turn my shop in to a building site over December and there was another one going that was warmer, drier, better lit and slightly cheaper to boot. I do like my creature comforts but probably best not to buy large milling machines until I've settled in.
I bought my set of ER32 collets and a #40 chuck for under a hundred on fleabay then sold the chuck so I got my collets for just over £70 which was good back then.

No I will CNC it eventually... I suppose boring head and a rotary table are the next things...
I already have a 48v 15A PSU and a 70v 9A one and the drivers I'll make myself... so its just steppers, ballscrews and other bits n bobs I'll need, but they'll have to wait a while...:rolleyes:
