MT Spindles for Lathes and Mills

[Antman]

Hi
I want to make a spindle tool using a commercially available spindle, perhaps a new spare part. I want something easy to put taper bearings on, hopefully just for that purpose, and with an internal morse taper. I can't find anything on the net myself. Any suggestions?

Taig and Sherline make small spindles,,,,but I don't think that is what you asking?

I'm not quite sure of what you're asking either. You want to make a spindle out of a spindle? What are your requirements, length, taper, bearing size, or do you want to make a tool to remove and replace bearings on a spindle?

Yeah not sure what you are getting at here. Many wood lathes have MT spindles maybe a cheap or used wood lathe would fit the bill and use the head stock.
No idea what you are trying to do but this should allow you to hold MT tooling and spin it either with a motor or add an indexing plate or gear and use it for simple indexing.

Like others, I am not sure of what you are looking for. Enco sells hardened and ground MT sockets in all MT sizes and various ODs but they are quite short (only 4.75" in MT3).
If this is any help try looking at

http://www.use-enco.com/CGI/INSRIT?PMAKA=214-8709

The series runs from 214-8701 to 214-8719

Hi,
What I want is basisally a naked spindle only with a MT2 or MT3 taper. The outside of the spindle should have maybe 2 opposite shoulders to enable one to fit a pair of taper bearings. Then I shall make the housing for the outer races of the 2 bearings, the housing to my own requirements. I suppose all I really need is a new spare spindle for some small lathe or milling machine. If there is a choice I will go for the one that has the simplest bearing requirements.
Thanks guys,
Ant

Ant,

There's a series of workshop books and there is one on spindles...it gives all you need (I think) to know. Here's a description and a link. I think you can order it on line for some place closer to you.

You might take a look at the repacement parts Grizzly and Little Machine Shop sell for the small import lathes and mills.

Ant: With your new info, then the MT sockets from Enco would work. They are long enough for two bearings and a pulley, gear or sprocket between the bearings. Longer might be nice, but the price is very attractive compared to buying a machine spindle. I haven't seen ground shafting with a MT socket in long lengths but it might be available. Don't overlook the possibility of buying the shaft and boring your own MT socket.

Hi Ant

Or another Idea if you can't find any spindle just like you want it:
You could buy a normal cylindrical shaft wiht a morse taper in it and then shrink fit or press a sleeve on it which has the required geometry. Or you just fit a bigger sleeve on it and then finish between centers. That way you could also be shure to get minimal runout.

If you dont' want to shrink fit or press on the sleeve, you can also glue it with loctite or some similar adhesive

Check with Little machine shop.com. They have all sorts of spare spindles. Here is a spindle for a 7x14 for less than $45.00. Machine off any and all parts of the flange that does not suit the purpose. http://www.littlemachineshop.com/products/product_view.php?ProductID=2027&category=
