Morse taper adapter

[Pete HillParticipant @petehill80830]

I hope some one can point me in the direction of a 3- 4 mt adaptor with and open end for a drawbar and an ejector ring for removal. I have just got a milling machine with a 4mt spindle which had an open ended sleeve in it. But having spent a nerve-wraking half hour getting the existing sleeve out some easier and safer form of removal would be great.

 

Tried MSC, RDG and Chronos but best I have found was a 2-3 mt version. I have thought of an alternative, if some what less professional solution, but if anyone knows of some where I can get one that would be grand.

 

Thanks pete

Hi Pete, A bit more info would be helpful,

1. What is the machine you have?

2. What tooling are you wanting to use?

3. Do you have an existing stock of 3MT tooling? If not, I would consider converting to R8 as there is a wealth of tooling available and a lot better than an MT fitting on a mill.

4. What is the drawbar arrangement on your mill., thread size etc etc?

You could always turn up an adapter to suit your purposes, MT taper info is readily available, if you have difficulty finding this, PM me and I will send you the relevant info.

 

I’ll have a look through my odds and sodds box, I have a feeling I may have a 4-3MT adapter somewhere which I no longer need. If I find one, it’s yours for a beer and the postage

 

regards

Hi Pete,

Just had a quick rummage in the workshop, I have a few 4-3MT adapters although they are flat tang type but could be adapted to take a drawbar. You are welcome to a couple of them if you wish, just PM me with an address and I will send them your way.

 

regards

Hi Graeme

 

Thanks for the reply, I will pm you if I need to take you up on the offer. The mill is an Alexander, bought recently in an auction and it came with the standard boxes of “stuff” some of it for the machine and lots of stuff that isn’t too. Once I have sorted through it I may need to give you a shout.

 

The spindles are both 4 mt, and most of the tooling I have acquired so far is 2 or 3 mt. I do though have a 4 mt Clarkson chuck so may just end up using that for the meantime. I am not sure what the draw bar is as yet, but there are at least two so far going through the boxes. There also appears to be a set of r8 collets and a 4 mt holder though that too is minus the ejector ring that should be on it, but I can make that up.

 

I will check through the rest of what I have this week and give you a shout if I need to take up your offer, but it might be handy.

 

Thanks Pete

Pete you could try Rotagrip, I can’t see one on their site but they may well be able to source something for you.

 

Now you have the mill you should be able to make a start on that crane engine
