Myford Connoisseur & Super 7 PLUS Countershaft

[Michael O’ConnorParticipant @michaeloconnor78257]

Hello,

I have a recently acquired Myford Super 7 PLUS (Nottingham) which has the large spindle bore and Poly-Vee Primary Drive, but still has the Vee Belt Spindle and Countershaft Pulleys. The lathe has never been used and has sat for decades (?). Sad story attached to it. As a result, many of the black oxided shafts and handles have developed surface rust and need cleaning and re-blue/ blackening. Fortunately, the ways and slides were lubricated, looked after and there are no issues there. He forgot to protect the shafts and handles or they were not looked after as carefully as the bare steel and cast iron elements.

So I was about to disassemble the countershaft when I realized that the countershaft bracket is different than my small bore Super 7, as I believe it has ball bearings instead of bronze bushes supporting the countershaft. It also doesn’t have a circlip on the left side as the original design does that allows the shaft to be easily removed. I have had several Super 7’s over the years and am completely familiar with the procedure outlined in the manual to disassemble and assemble the countershaft.

I searched this topic and found one result here that I think was from 2011 which received no response. No luck searching on the Internet either. Sorry for no link now. I am afraid that I will lose what I’ve written if I leave this page. Will reference this in the next post.

When I bought the lathe, I ordered some accessories from Myford Halifax. I asked James Bracewell if they had a manual or updated parts list for the Super 7 PLUS or Connoisseur Lathes. He told me that Myford hadn’t gotten around to it and they haven’t either yet. I received everything that came new with the Myford Super 7 PLUS from the original owner. This included the same manuals that I have for my 1994 small-bore Super 7.

Am hoping that someone here can offer some advice on the countershaft disassembly.

Regards,

P.S James Bracewell from the current Myford has been an absolute star when it comes to my orders and questions. Fast response. Fast shipping. Great customer service.

Instructions for Changing Spindle Belt

This thread was the only reference that I have found that relates the Big Bore Myford Countershaft. It was about an intermittent noise, not changing the spindle belt or disassembling the countershaft

I have a big bore S7 with vee belt drive to the spindle and the countershaft runs in bronze bushes.

Thanks for the reply.

Will take some photos later of the countershaft casting.

I have added four photos to an album. “Myford Super 7 PLUS Countershaft”

The counter shaft is 7/8” diameter. Upon closer inspection, it appears that the countershaft casting is counter-bored for oil seals. I can see some numbers but can’t make them out.

The spacer and retaining circlip present on my 1994 Super 7 is not used to retain the shaft on this Super 7 PLUS.

The oil seals are a nice addition.

Hoping someone here has taken one of these apart and can offer some advice on how the shaft is retained.

It was after business hours when I emailed James from Myford on Friday. When he replies, I will share what I learned .
