I also am not very happy about Cowells 10 day turn around, I can’t see it takes that long to pack and post.
Finished off three out of four new chuck back-plates for Cowells ME90 lathe, Have just upgraded spindle to later M14x1. threaded nose. Purchased a few of the Arceuro 62mm backplates and shrunk them down to the requisite size. Cocked up the one for the 3 jaw chuck due to a config error on the DRO, so shrunk it down lots, put a sleeve on it and fitted a modified M12 backplate to it. Switched to ER16 collets rather than the Cowells original, the backplate for the 4 jaw chuck worked out okay. Just waiting for one more to remake for the 3 jaw chuck.Can now move all chucks between Cowells ME90 lathe, Cowells Mill, BCA jig borer, Aciera F12 and Myford S7.Now have a surplus M14x1.5 collet chuck with metric and imperial collets and couple of M14x1.5 backplatesColin
Henry,Unfortunately no. I sold the M15x1.5 bits on.There is a guy called Howard at a company called Triona Ltd who has a website www.myford-lathes.com. He sells spares for a number of small lathes and carries a selection of used Cowells parts. He can be contacted on 01225 812155 or 07753 610420. I have had various bits from him which have all been excellent quality.I opted to change to a new M14x1 spindle as this gives lot more flexibility on supply of chucks. Many of the usual supplies will have M14x1 parts. I bought the new spindle direct from Cowells Machine Tools. Not particularly cheap but I thought it worthwhile.Best of luck looking for bits. Have fun with the lathe.Colin
The cheapest way to move forward with the older pitch Cowells nose thread is to buy yourself a M14 by 1.5mm tap set and knock up a batch of back plates and adapters for any other things you want to mount on the nose . Jo
It depends on how rich you feel You don't want to go over 65mm for a chuck on a Cowells. The Bison key operated chucks as fitted to the later Cowells are very nice. The Sherline Chucks are good. I purchased a Chinese Sanou KO1-63 for Shoey (Schaublin 70) expecting the chuck to have short life but as Shoey is a collet chuck I do not expect to need to use a chuck on her, so this is just a back up. I also attempted to buy a 4 jaw SC Sanou to be supplied something made in India which is only suitable for a door stop.The Cowells original 3 jaw were similar to the one for the Emco. IF, IF, If you can get a good one these are ok. There is one currently on Fleabay at a price which will rapidly increase The seller also has a backplate that no one has bid on Jo
Sherlines have an imperialist thread mount so you need to make an adapter. While you are making one make a M14 by 1mm adapter as well. (
