Are the spindles on these hollow so a long piece of material can be held and machined, like in the 5C collet system on a lathe? Need to do some milling on a 12 in. long piece and have never seen one of these in the flesh.

Enco has their brand for $29 and phase11 for $59. Can anyone give me some feedback on these two brands. Both POS or is the $59 one better. They give specs on the phase11 that look decent, but, they can claim any numbers they want. I wonder if they really meet those specs.

Thanks for your help,
Chris

You can pass up to a 1" shaft though them.

Some of them are not machined on the base , so has for example if you wanted to slide it against a rail on grinder or pins on mill.Chris

Watch Ebay.

I sold a Yuasa for 35 bucks a few months ago.

I've got the $29 Enco unit and it does have a hollow spindle, about 1.05" ID. I haven't had a chance to use it yet but it seems to be very well made.

From what I can tell all of the spin index for $60 and under are the same. I have purchased them from several different places to see if there is a difference. Can't find any real difference. All have the number of PF70 with a different name. They do not have the sides machined. They now make a tail stock to match these. The only place that I know that handles them is Lathemaster in Baton Rouge, LA., they have a web site. All have a through hole that will handle at least 1 inch.

There is one that looks the same but is very accurate and machined on the sides is sold by
by MSC for about $600.00.

Hope this helps,

Joe

If the base isn't machined and you want to place it on your table correctly, then it would be necessary to indicate it in using the spindle as a reference. I guess that's the hidden price you pay when you buy a $29 "precision" item. Thanks for the info.

You only need do it once.
Pack up off the bed, indicate off the spindle and run a clean up pass down the sides.

For $29.00 it's not rocket science.

PS.
I still think they would be better off making a ER32 version instead of a limiting 5C.

I have a Phase II and like it. It has turned out to be one of my most-used milling machine accessories. I leave it clamped at one end of the table most of the time.

I've put 1-inch diameter stock through it; haven't tried anything bigger.

I have one of the $29.00 that you speak of and it is well worth the money for what I have used it for.

I was going to order one of the cheapos and was wondering if I could set it up and mill it flat on the side. Smarter people than I have already done it. Thanks John S. for verifying it can be done and thanks to everyone for the feedback.

Just a followup:
I don't know why, but I ordered the more expensive phase 2 index, and just got done checking it out. There was a machined surface on the front of the base, where the collet goes in. I set it up on the mill using a square on this surface and the front of the mill table. I placed my 0.5 x 6in. reamer blank, that I use as my reference, in a collet and set up the indicators to see how bad things were. Well, I was sure surprised, when things checked out good. Overall quality was also pretty good, so I would have to say it was a good puchase for $59 and I didn't even have to do any machining to it.

I've got a set from Lathemaster with the tailstock and now I have to take the time to not only make sure the center heights match but that I mill a 1/2" keyway in the bases and either shoot holes for mounting studs or mill slots for them. Along with grinding the sides square. John Stevenson (?) had a modification for ER 16 or 32 collets he did on on. John could you post drawings?

Drawings ??

DRAWINGS ??

That's a hoot, better than Weirds blonde joke.
We don't need no steenking drawings.

Does this mean I have to go out into the cold and dark and take measurments ?
