VMC300 Toolholder question

[m_c]

I think Boxford and Coventry used to collaborate previously(at least) on toolholders.
I seem to remember a chap talking about some Coventry toolholders for his VMC190, and i think it`s the same toolholder.
Still havent got any answer from Neville at Coventry yet though.

The Coventry Easy Change system was fitted to lots of machines, however it doesn't use a pullstud, which is why my money is on some form of Boxford specific custom holder.
Boxford aren't exactly renowned for using established standards.

The presence on the Boxford holder of the locking ring groove in the same place as on the Coventry holder when with a pull stud it isn't required makes me suspect the Boxford is a modified Coventry, anyone conversant with, say the BT30 holders would recognise that the slot is redundant and that it would be absent on a fully custom-ordered part ;-)
Also there are the suspiciously thin walls above and below the tool changer disc slot, intriguingly designed to fit into the standard Coventry holder drive disc size and position :D

I'll put a fiver on the Boxford being a modified Coventry

Got answer from Coventry today.
The toolholders are custom made for Boxford.
Production stopped in 2012, but they can make them at 156£ each with the groove. However, i strongly belive it's the same as their standard Easychange toolholder(without the groove).
I will order 1 and check similarity with the ones i have. For nearly 60£, i could could even fix that groove myself in my lathe.
The pullstuds however is a Boxford product according to Coventry.
Will have to make them myself ��

Jepp, noticed but they are out of Stock on the EC-ER32-050, and they don`t have the EC-SM22-015 :-(
But i noticed Engineering Supplies in Hamilton got it in Stock at a good price(approx 76£).
They even have the 22mm Spigot Easy Change Shell/Face Mill Adaptor(believe its the same as the Coventry EC-SM22-015) in Stock at 87.44£.
Any experience with that company?

I bought several holders from Engineering Supplies, their shipping was fast and their service was excellent, it's a shame Tony is out of stock of the ER32, I was going to buy another from him for me for Christmas,

ive bought and used Easychange collets from Engineering Supplies, Weldon type. work fine in my VMC190. Now, getting the M8 pull studs from Boxford can be pricey enough - £22.17 plus VAT plus Delivery (probably crazy for Northern Ireland)!
