morse taper data

[kd0afk]

I would like to have a chart of the MT dimensions. I found the one on wikipedia but it is in mm and while i could do the conversion it would be nice to have one in inches. The B&S, Jarno and Jacobs are all in inches, so why is the morse section metric. Seems retarded to me.

Thanks, I don't know why someone would combine inches and metric.

kd0afk,

Here is a link that gives the formula for calculating offset:

http://vlabs.iiitdmj.ac.in/Manufacturing/Exp2/offsetting.html

The page says the fomula is metric, but it will work with imperial unts.

Instead of offsetting the tailstock itself, do you have a boring head with a taper to fit your tailstock? Set the boring head up with the adjusting slide parallel to the bed and offset the head instead of the tailstock. Much easier and no hassle re-alligning the tailstock.

No, I have to offset. I just found Halligan142's video on the subject and I think I have it. Thanks
I will probably be using the formula in the link you provided. I like the level of accuracy it gives as opposed to "length of part x taper/foot / 24

I'm going to disagree. It is essentially Imperial and good old USA of A.

It was originally dead simple - a 10" sine bar with a quarter of an inch bit of packing.
No more- no less.

goldstar31, I'm not sure what you're disagreeing with?

kd0afk, I put the formula and Morris Taper specs into a spreadsheet, would you like a copy?
