At the moment most of my attempts at turning turn out like that. The Guy at work is Super busy at the moment doing some thing with a University down South. But today I went to Cromwell tools with a list. Then I was given several pieces of scrap bar stock and some tuition. I have been gazing at them all day the finish is so good you could all most use them for a mirror. I just wish I could remember what he showed me old age is not for the faint hearted. Believe me. :roll:You can either pressure knurl or cut knurl, I use the pressure knurl process with two knurling wheels, I am tempted to move to cut knurling however the tooling is super expensive and not easy to set up. The really annoying part is I can get perfect results time on time and then suddenly I just rip the bloody surface to pieces and the part is scrapped. Very frustrating...

Re: test
Machined finishes are not a real problem, it is just down to cutter profile and feed/speed. As the majority of my work is from 6mm to 34mm diameter my speeds do not vary hugely and I run my finishing cuts at the lowest possible feed speed. I seem to use more DCGT cutters than DCMT cutters of around 0.2 and 0.4 radius. I also use these with fine stainless work as they cut as opposed to push the material away.
This is just what works for me and the jobs I do, if I was hacking up large lumps of cast it would be very different.

I have attached a copy of the Myford lathe manual, I have broken it into 3 PDF,s as it was to big to attach as one file. I would assume that the limit is 5Meg.
Hope this is of use to someone if they want to buy your lathe.
Best regards
Fred
Ps will post 2 other sections shortly.
PPs My first lathe was a ML7, great piece of kit, only reason sold it was lack of space due to the other two lathes in the shed, A boxford and a Harrison L5A. :shakeshout:

Re: test
Ovenpaa why DCGT as opposed to DCMT.
Re: test
Fred, many thanks for the manuals, always handy even though I am selling the little Myford.
Alpha, it is all down to the job. Today I was using DCGX 11 T3 04-AL inserts (Sandvik) Quite pricey however the results are superb and people like shiny things.

What would you recommend for getting a nice finish on silver steel or stainless.Alpha, it is all down to the job. Today I was using DCGX 11 T3 04-AL inserts (Sandvik) Quite pricey however the results are superb and people like shiny things.
I have CCMT and DCMT inserts and holders.
