Spindle nose adapter for Delta-Rockwell 11" lathe (#25-100) with L-00 spindle
I have a Delta-Rockwell 11" (#25-100) lathe and I'm looking for a
source for adapter sleeves for the L-00 spindle, which I believe has a #4-1/2MT center hole. I'd like sleeves for #3MT and 5C collets as well as a spindle nose protector. Anybody have any experience/advice regrinding a #5MT to #4-1/2? TIA, Dan |

According to Royal, the taper is actually a short 5MT. Put prussian blue on your 5MT and check. I got a 5C adapter from Royal that works well for mine (same model). The part number is R184024. I made my own spindle nose protector and drawbar. See http://www.metalworking.com/DropBox/...oj-5CParts.JPG and others in that series. My homemade adapter sleeve sucked, and was replaced by the Royal unit. The rest is in service. Pete Keillor |

Spindle nose adapter for Delta-Rockwell 11" lathe (#25-100) with L-00 spindle
I've got a couple of extra 4-1/2 to 3 MT adapters, used but in pretty decent
shape. $25 each plus shipping (USPS preferably). Pictures on request. "Dan Allen" wrote in message om...

That Royal number matches the one on a closer that's part of a complete lever unit currently offered on E-bay. I'll give them a call for pricing. I'd already about decided to fab the nose protector - there was one on E-bay (Clausing NOS) over Thanksgiving but I lost the auction 8-( WRT using a MT5/MT3 adapter sleeve, how short is "short"? According to the specs on the Morse site the tapers are real close(MT5=.052626/in, MT4.5=.052000/in) but the OD's barely overlap (MT5=1.74800/1.47500, MT4.5=1.50000/1.26600). An MT5 sleeve is only going to fit 1/2" deep in an MT4.5 socket if I did the math right. To get anywhere close to the 4.625" socket depth of the MT4.5 you still need to reduce the MT5 OD by nearly .25". I don't see how a MT5/MT3 sleeve could be made usable without regrinding the taper.

That is the case with the Clausing that I have, but there is no certainty that other makers (e.g. Rockwell/Delta) use the same internal taper on an L-00 spindle nose.

If it is a short MT-5, it will be using the large end, not the small end. The advice of using bluing will allow you to find out what part of the MT-5 is actually being used. If you discover that it is indeed only using the small end, then it probably *is* a MT 4-1/2, and I would suggest buying one from Clausing, if you don't have a taper turning attachment and the ability to set it to match the internal taper of your lathe spindle, (Hint -- use an indicator on the back side of the taper, and set the taper attachment to produce no change in reading as it is cranked in and out.

The Royal number given in above posts is correct but Royal discontinued the production of this part and is out of stock. There is a company in California that makes them and I just ordered one. The name of the company is JFK Company and their phone number is (818)767-8573. It isn't cheap but they make these parts and will do it right. |
