ER32 Adapter(purchased)

[b4dyc]

Thank you all
It looks well made but the proof is when fitted to a lathe.
From what i remember, it was about 6 - 7 thou out.
I will test the taper, as suggested DaveH. It would at least confirm the collets are true? I assume testing at the end where i did this on the video will be ok?
I am not sure I have the gear to fix it (or the knowledge tbh) Maybe a dremmel could be fixed up to grind the small amount to make it run true if it is lob-sided? Is there a tutorial or page that has this done by someone else? The reason i think grind is that the metal seems hard.

The register on the lathe is good at least

I like the idea of fixing it to the silver steel and test the runout. I will take another video of different ideas and see where this leads me.Thanks Steve

I am guessing then, that even another one may have more or less errors on it John?

The 3 jaw is one of those that can be adjusted so i could with a bit more time get it a bit closer. Sure is easier than using this ER32 collet adapter
But what i would like to do is transfer from the lathe to the George Thomas dividing head that i own (not used yet!)
Thanks all for the new list of things to check
