Bill, I will get some spring steel ordered and make one up along with the spring cap and drawbar.
Thank you once again for your help.

Hi Bill.
Not me with the Olympus, I am a Nikon man, started at 17 with an Olympus OM10 went from there to Nikon D90 and stayed with it, I could get on the never ending money pit of camara upgrades, but my eyes are just not good enough to justify it, who's are?

This is a lovely looking old machine, I have nothing against Chinese machines,as I have never owned one so I cant judge( I have read a little about them) I like machines from an era when cast iron was used because it gave a machine, mass and rigidity.These machines give more than a working lifetimes service, and then some, and still survive for people like us to adopt them and look after them in their later years.

Hi guys,
I have just bought( not Delivered yet) a machine tool re thread title.
I was wondering if any of you lads have, or have had said machine? I bought it as I feel it will be an interesting little addition to my tooling. As a new forum member( I have lurked a little), I will attempt to post pictures on its arrival, if that would be of interest to anyone ?
Cheers, Garry

Thread: Centec question
29/01/2019 15:16:32
Hi Bill, what would be a real help would be the diameter and unsprung length of the spring and SWG or dia of spring steel itself.
On a different note, I bought an old Turner Universal tool and cutter grinder last night, it looks interesting, delivered Saturday, I cant wait.

Bill,thank you for taking the trouble to photograph your drawbar assembly, now the top end makes sense, I have no return spring or spring cap, I have not used the quill yet( not had enough air between a job and a vice to even think about drilling a hole or sinking a slot drill), first job on was the riser block dovetails, then copy the clamps, then machine the clamp pockets.it will be good to have the extra 120mm of space under the head, then I may get chance to use the quill, mine came with a Mitutoyo digital caliper attached to the quill,which could be useful in the future.
Bill I like your idea,
I think I might look into a drawbar with a 6mm thread they dont need much force to lock taper and easier to manufacture with a strong thread leaving enough material to make 3/8 and 10mm plugs as needed.
Once again thank you for your responses.

Gary they look supurb!
I have a length of 80x80x450 long to make a long overarm
Your not kidding about the amount of work, a 120x80x225 block of cast is right on the limits of a 2A's machining envelope. 2 setups for the clamp pockets at 30degrees to virtical and holding the thing down and clocking was a faff but on saying that I enjoy the challange. Thanks for the post, do you have any long risers without a home?

Wow, what a response, thanks lads,I've downloaded the details for the machine ( thanks Bill) and the link to the lathe.com website has been a constant companion over the past few months for me and helped me choose the Centec as a machine to have , but thank you anyway Brian its good to know you guys are there to help.
Armed with the forum info I popped off the top hat which is not original by the way, it is a half st steel flask welded very neatly to a flange with the cup lid a screw on cover, someone must have misplaced or damaged the original.
My drawbar is 3/8 BSW at the end it looks like a length of screwed rod that has been releived of the top of its thread to .336(8.53) Dia along its length
I thought it looked a bit iffy when I saw two nuts locked together at the top.
This drawbar came out of the bottom when I removed the nuts, I imagine it may have been 5/16BSW in original form, to fit from the top(thats why I had to give the bar a light tap with a piece of brass I have to release the morse lock.so a replacement like for like will retain my 3/8 BSW tooling and a Drawbar with a 10mm thread could bring me in line with current more abundant tooling.
I have recently made a morse adaptor for a the dovetail cutter I used for the riser block( no space for the material and a collet chuck) the riser is made from 120x80x225 cast iron bar.
Anyway I am rambling!
Thank you all for your responses
Take care.

Hi all,I am new to the Model Engineers Forum, my name is Garry, I spent a little time in engineering,many moons ago, over the many following years I have often missed the ability to make, repair, manufacture from mind to metal, so much so.that I have recently purchased a Centec 2A with a mk3 head and I have just finished machining a riser block for the said machine, its not been fitted yet as I am awaiting a new drive belt some 240mm longer than the one in situ.
My question is, as a new owner of, what I can only say is a really nice machine is: Does anyone here have a Centec Mk3 head? And if so could I ask as to how the drawbar is removed? I would like make a new one? Well I dont know the condition of drawbar thread as they tend to get a bashing to break the morse lock.
I have also bought a Myford ML7.
Thaks in advance, Garry
