Geez....they've just come on sale for half the price of the last one I bought.
Arrghh...I need a reason to buy a couple more. http://bbs.homeshopmachinist.net//biggrin.gif
I still haven't taken the one I bought out of the box yet but I just got laid off from the cement company contract so I have time to play again.
I'm going to build an endmill sharpener with one. Can use another on the mill for whatever....what can I do with the extra one?
Any ideas please?
Thanks!

Russ, make a piece that is mounted on a channel with the spin index and a tailstock so it is easy to mount on the mill as a fixture. see picture. Lot of things you can make with the spin indexes.

LOL! Thanks Joe!
I'm in....going to order a couple!
Only thing is, they also have a nice Groz swivel angle plate for the mill on sale too.
I could also use that. Be darn handy for milling the new gib I need for my lathe http://bbs.homeshopmachinist.net//biggrin.gif
I hate "toy" catalogs!

Heh. Russ, you must have just gotten the latest Busy Bee catalog like I did. Good deal for $40 CDN.

Dan,it's Busy Bee Tools in Canada.
Even I don't get their catalog anymore.
I just bitched about it when I phoned in my order. I found them online...takes over an hour to load the pages (sigh).
Anyway...I ordered two indexers and the milling fixture.
I love payday!

Don't know if anyone is doing them in the States but they are now importing the dual purpose 5C and ER32 indexers into the UK

http://www.arceurotrade.co.uk/en-gb/dept_205.html

About 2/3 of the way down the page.

Sir John..there is some very cool stuff in that catalog!
I like that DRO for the Myford crossfeed.
Very neat!
Now...I see the indexer listed a a "Stevenson"
Would that be someone we all know of around here? http://bbs.homeshopmachinist.net//biggrin.gif
And would the previously mentioned Sir Person perhaps sell the adaptor for ER32 collets to people who have just bought 3 spin indexers?
All those nice, cheap ER32 collets on Fleabay...just waiting to be used http://bbs.homeshopmachinist.net//biggrin.gif

Russ,
The adaptor on it's own is no good as the spindle nose needs to be threaded on the OD to take the ER closer nut.

Nice thing about the ER 32 collet system is that they cover a full millimetre [ 0.040" ] of range with no gaps.

The DRO for the Myford is just one of the DRO displays off the Seig C3 lathe as sold by Little Machine Shop etc..

These are just a shaft encoder but to work correctly they need to have a 20 tpi thread.

And before anyone asks about backlash in the thread you compensate just like a dial, in fact that's what they are, a digital dial.
Main advantages are you can swop between imperial and metric at the touch of a button, set zero anywhere you like and you don't have to count turns.

Just an FYI for the US contingent. Enco has what appears to be the same unit on sale for $42. Or you can get a similar one without the collet rack for $29.

Thanks John! Ah well I maybe owning four of them when I can find an ER32 indexer here someday.
David...lol! I looked at the Enco catalog for the spin indexers.
The first thing that came up was funny!
A "W24 POS indexing plate"
Seriously..that's what it says http://bbs.homeshopmachinist.net//biggrin.gif
