4 1/2 morse taper

What size and age is your Reed lathe---maybe it takes the 6L collets which max size is 1"-----Dave

Mine is somewhere after 1897 and no newer than 1908. It has the feed pulleys outside the change gears and says F.E. Reed co, not F.E. Reed & Co. (think that's right) It has an 18" swing, about 60" between centers.

I just did some researching online in mh and apparently there was a Reed taper (never simple, is it?) which was only used by two companys. I assume this is the two Reed companies or maybe Reed-Prentice. Anyway it's .6 in per foot or .05/inch, which is the same as a jarno taper but shorter. This would put the dimensions close to a Morse taper 4 1/2 as the small end is 1 1/4 and it's 5 1/16 long. Not close enough, though. So I guess I'll search eBay for a #12 jarno now n see what I can find.
 
I have a used MT 4½ to MT 4 sleeve for sale, $35 shipped, anyone interested?

MY 11" rockwell lather I believe is also 4.5 mt and also has the Loo chuck attachment
 
Your Reed lathe of that time frame probably is a Jarno taper in the headstock. It probably had a Jarno in the tailstock originally also.

My Sheldon Sebastian has a 4-1/2 Morse taper that is 1.625" ID at the face, instead of 1.500".

I was just wondering if anyone had an idea where I could find a 4 1/2 Morse taper adapter sleeve or just somethin with a 4 1/2 mt shank I could cut off and reuse to make an adapter. My ancient Reed lathe, as near as I can tell, has this taper in the spindle. I've heard that some Clausing lathes had it too so maybe someone manufactures them still. I've had a search on eBay for quite a while with only one showing up and I missed out on it. I've checked the major supply houses as well. Maybe someone knows of another vendor. Thanks in advance.

Grizzly should have aq 4-1/2 MT adaptor.My 10 x 22 lathe has that taper in the head stock.I have a dead center for it but no adaptors.Check their website for parts info.You may be able to download the part #.
You could make one,

I just checked the online manual,calls for a #4 MT on my lathe.Went out to the shop,the dead center is a 4-1/2 MT.My written manual also calls it 4-1/2MT
I have made a couple of taper fixtures for my lathes,#2 #3 MT.
I do not have a taper attachment.I used a boring bar in the TS with a 60° point instead of a cutter.The boring bar can be offset instead of offsetting the TS.Find the small and large diameters for the MT. Practice on scrap,I used a piece of wood. Only took me 10 tries before I got the correct angle.One of these days I'll make or buy a sine bar to set the angle.

Thanks. I was wondering that so I put some pencil lead on the taper I have n put it in the tailstock to be sure it really was a 5mt and it showed contact in two spots so it must've been reamed at some point. I'm going to try and measure the spindle more accurately maybe that's been changed too. A 4 1/2 mt is very close to a #12 jarno from what I've found.

Thanks. I might try that. My goal is to have an adapter for collets, maybe 5c. The four jaw for this lathe only closes to about 3/4"

My guess is that it would be a difficult item to find. On the other hand,
it would not be very difficult to make one if you have a taper attachment
or even with the offset tail stock method. I will look in the Machinery's
Handbook and see if I can find some dimensional information on the
4 1/2 Morse taper for you.

It,s now a few minutes later and there is no mention of a 4 1/2 Morse
taper in the 11th Edition of the Machinery's Handbook. Do you know
for sure it is a 4 1/2 MT taper? If not, it might be some other type
of taper used like Brown and Sharpe or Jarno ETC.

littlemachineshop.com lists dimensions for Morse tapers. Here is a paste from their website:

A little hard to read; spaces don't upload. There are seven columns with headers. Much clearer on the site!
