K&T 2CHL New to Me

Don Kinzer · Dec 11, 2017

I recently picked up a K&T 2CHL Universal, serial number 7-7611. The serial number listing that I found at vintagemachinery.com only covers lots 3836 (Nov. 1941) to 6175 (Oct. 1948). Is there another list available or can someone tell me the usual details for this mill?

Also, I haven't yet figured out the differences between the 2H, 2HL and 2CHL models. Is there a source for such information?

Thanks.

I forgot to mention that this mill is the 3HP model. It is currently wired for 440V but I'm in the process of changing it to 220V. I've ordered new heaters and I've pulled the motor in preparation for re-wiring.

Also, I'd like to find a parts diagram for this mill. I have one for 2CH but I haven't found one for the 2CHL. The X-axis handwheel has its handle broken off and I'd like to remove the handwheel to remove the broken stud and replace the handle. It wasn't immediately clear how the handwheel comes off - removing the center nut did not free it as I expected.

In brief, H is early (about mid thirties?) compact design. CH is improved. Its easy to assume the C is to mean "more suitable for carbide tooling"

1H/2HL are smaller/lighter than 2H

2HL has 6" longer table than 1H - the only difference

"Compact" as in smaller/lighter/handier/less power than the K series design

The later lot list on VM

The 2CHL parts & operators manuals are on VM also. I’ve used it so much I’m going to send a donation this year. 2H is a bigger mill & #50 spindle. The 2CHL, 2HL and 1H all have a #40 spindle. The 2CHL has a larger table screw and a backlash eliminator.

Thanks for the replies. Somehow, I missed the second part of the serial number list.

I did retrieve the installation and operation manuals from Vintage Machinery for the 2CHL and also what I thought was the parts manual for it but it indicates that it is for the "5 hp No. 2 Model CH". Of course, mine is the smaller 3 HP 2CHL. I've seen that one of the differences between the 5 HP models and the 3 HP models is that the overarms are smaller on the 3 HP unit - 2-7/8" vs. 3-5/8" on the 5 HP unit. I suspect that there are other differences also, not least I suspect that the main casting is larger as the 3 HP motor is a relatively tight fit in the motor bay on mine and I don't think a 5 HP motor would fit.

I'll go back to VM and try to find the parts manual for the 2CHL.

I suspect that there are other differences also,

Yep, like 1000 lbs in the '57 catalog Plain CHL compared to Plain CH

Well up from the 700 odd Lb difference in '39 HL to H

The lot number list is in four parts because the book I had to scan is so thick...It took me quite awhile to scan that book with a little flatbed scanner but now all can share... Enjoy! Ramsay 1

It's easy to merge multiple PDF files using the free PDFill Tools application. I've combined the four parts into a single PDF file for my own use. I could post it back to Vintage Machinery if you think that would be helpful.

I looked again on Vintage Machinery site and can't find a Parts Manual for the 2CHL. As I mentioned earlier, what I thought was the right one is actually a Parts Manual for the 5HP 2CH.

Does someone have a scan of the 3HP 2CHL manual they would send to me?

Thanks.
