ER32 hex block

Where can I get a good ER32 block in hex format?

Accusize maybe?

Anybody got a link to a good one? ie the distance from the center axis to the edge of each hex side is exactly the same. AND (picky John) each hex side should be exactly parallel to the one on the otherside. AND the angle from one hex side to the next is exactly the same. or within a thou or so. yes?

Does anybody have a commercial one? - is it good and meets the above requirements? Got a link?

There are lots on ali, ebay, amazon, comments seem to indicate many of them are pretty poor, or the guy thinks it's great, gives it 5 stars, but he hasn't tried it yet. :rolleyes:
 
Shars has one where they actually talk about the accuracy of the block...I'm not sure the accuracy makes sense for the hex shape - more like the square one.

Over on HM this one was suggested. 12 sided so works as a square and hex.

Here I've drawn a hex and a 12 sided polygon to compare. It is a bit weird to have 12 sides - I'm not sure what the extra sides would be used for.

So you can do three sides too?

@johnnielsen @Dabbler @John Conroy you guys seem to source good stuff - where do I get one?

I can't recommend any seller's product. If it were me, I would buy an ER__ mounted on a short straight spindle and grab a piece of my large 12L14 hex bar and drill/bore a matching hole in it with a locking set screw or loctite. Perhaps machine an appropriate step so the ER spindle goes in far enough that only the nut protrudes. If you want to do it this way, I'll bring you a chunk of the hex bar.

Sorry, devil made me say that. I just couldn't resist after seeing @Janger 's comment about guys posting ratings before they even tried them!

Couldn't resist using that GIFF again either.

What the F is wrong with me lately?

Yes, combined with a ball bearing nut I had no complaints.
@PaulL bought them from me.
