I have a 5C adapter but would buy a 3MT reducing sleeve if they were hardened and ground and available for under £30.



@ 'Me.' for info. ^^^

My figure of £30 was based upon cost of a 5 to 2 MT reducing sleeve bought from RDG Tools in 2019 for £15. Basically I would be prepared to pay twice that sum for a smaller sleeve and suspect there would be a good number of others like me who would pitch in quickly to buy one at that price level.

Right guys and gals, following this thread I have done a bit of research and the two 'discount' UK suppliers of sleeves will not be getting 4.5 taper sleeves even if we need a batch of them.

I have however spoken to a local precision engineering firm who can machine down a small batch of 5 to 3MT sleeves to 4.5MT (actually to match the taper on my original Boxford VSL collet adapter sleeve so I know it will be 'right'

It will be CNC turned using carbide tooling and he has quoted a 4micron surface finish which I am sure will suffice or needs.

The internal bore (which takes the wear) will be as supplied by the importer.

I will put an advert on this site when they are done which will be at the £40 / £45 mark if I find I have extra costs to carry but for those who contact me now wanting one 'for sure' I will be letting them go at cost which should be the magic £30 plus postage.

Lead time on machining will be 6 to 7 weeks.

Please PM me quickly / over the next week if you want one (or how many) as this will be s strict;y limited batch and `I shall be making the same offer on the Boxford site.

Basically I am doing this at cost to try and help fellow Boxford VSL users.

If others know of Harrison etc users who need 4.5 sleeves please pass on the message.

Just a quick update on this.

I have arranged for a batch of 24 to be made by paying a precision engineering firm to CNC turn 5MT-3MT adapter sleeves down to 4.5MT (the entire stock of 5MT sleeves from the selected 'ME Partner' supplier) with a quoted finish of 4 microns.

I am taking UK pre orders for these (see ads) This is to get one myself and to help others who are struggling to get one of these adapter sleeves. I am not looking to get a profit from this.

Over the last 24 hours I have received requests for half of the batch so it looks as though I should be able to re-home all of the sleeves by the time the machining is completed (6 week lead time)

'Where there is a will there is a way'!!

Anyone wanting dimensions of almost ANY Taper should look at the "Tools-n-Gizmos" site for Machine Tool Shanks.

I have a sneaking suspicion they won't be "unspoken" for long.

Last one now, be quick if you want it as I shall not be doing this again!

I shall be taking two reserve requests after that one and will then remove my advert.

All now spoken for but I can take two more names in reserve in case anyone changes their mind at last minute.

Thanks everyone for speedy uptake on this - makes it easy for me and reduces anxiety over recovery of my outlay.

Latest update - the Engineering firm advises that the sleeves are scheduled in for machining next week.

I am actually away from 3rd to 8th November so will be in contact with purchasers next week to firm up arrangements for payment and postage so that all is set to post the sleeves out between 9th and 12th November.
