Nice job Rod.

One thing I've recently done with my Cowells is to do away with the weight of the motor proving tension alone. I've taken Jo's idea of holding the motor stationary against a spring. This improved the finish I've been getting noticeably.

Thumbs up for the DRO setup, but the whole project seems to have been a very worthwhile one. I can't recall, but did you make a collet chuck for it? Nice one to have finished by Christmas.

Cheers, Hugh.

I know this an old thread, but I just had to congratulate you on the fine job of refurbishing the lathe and documenting it. Very enjoyable, THANKS! I got several ideas for one of my projects.

I have just returned from visiting an old friend who has an old example of what appears to be this same lathe (but with a "zyto"? brand) which will soon be looking for a new owner. I didn't pay it that much attention, but it's painted a cream colour, and definitely has that helical-gear-driven leadscrew arrangement shown on this flexspeed. It had a tailstock and compound topslide.

If anyone is interested then let me know and I'll put you in touch. It's located on the Surrey/Hants border.

Bottom of the page.  Zyto was a brand name of Tyzack, the well known, at the time, tool factor.  Lots of badge engineering.

Rod, I somehow missed this addition of the dro's to the flexiispeed. Looks very good.   I wouldn't mind seeing a couple of closeup photos of the brackets you have fabricated.  Having recently fitted dro's to my cowells mill I quite fancy them on the cowells me90 lathe. I did use the magnetic read heads from machine-dro and use the yuristoys android app and his electronic design for the controller. I can use this for the lathe as well if I use the same readheads and magnetic scales.

Regards,
Colin

Rod,

Many thanks for the photos.  That's given me confirmation of some of the ideas I had in mind.  I'm not sure whether its an optical illusion or not but there looks to be more depth of metal on the saddle compared to the Cowells ME90.  How many adjustment screws are there for the saddle gib.  I was thinking I had three, but it may be the one in the middle is to lock the saddle.  Do you have the third screw or have you removed it and the hole is it covered by your bracket.  I would need to leave a small hole in centre of the bracket for an allen key to lock the saddle.  One advantage of the magnetic read heads is that I would not require the covers over the scales, which might simplify things a little.  Both the scales and read head are fully sealed

The image below shows the brackets I made for the mill.



Hopefully I can make something similar.
 
Thanks,

Regards,

Colin
