Not really John. You'd have to have the nut on the bottom of the scriber.

Yup just noticed that but if it had been fitted opposite before having the cutaway machined in then the nut would be at the top.

Nice looking bit of kit there Bernd :thumbup:
I like the quick to set-upness (yer it's a word! ::) )
Don't really need one myself though. Figure my vernier one does it. But for those who don't have them.... Or just want one? Then it looks like a nice easy project.
As you say, you don't need sizes.
These could be any size from an inch upwards, all the information is there in your pictures :clap: :dremel:
John,

Does this mean not drilling and splitting the cotter clamp? Cause if this were the case and the clamp was left solid. Would it not pull on the round shaft of the scriber arm arbour when tightened? possibly more as wear takes place?
Thus making it sometimes frustrating to set as the scriber tip would possibly move by a fraction as the bar could rotate slightly as it was pulled tight by the screwing action on the brass knob?
If I'm getting the wrong end of the stick, sorry. But it sounds like that's what your saying?
See, I'm figuring the spring keeps the lower section of the clamp in contact with the arbour and the screw/knob then pushes the top part of the clamp into place. Thus minimising any effects on the arbour and hopefully eliminating possible rotation. But that's just what I think it's for?

Yes I will. I figure I might do a little write up on it. I did one similar earlier to do a counterbore tool. I wish I had my Grizzly lathe so I could turn the ball on the end of the tool, unfortnatley the Grizzly is in many pieces awaiting a rebuild.
I've just about worn those books out from reading and rereading the stories and how to's. Trouble is you can get :proj: from going through them. :lol:

Bernd:
Yes your right John, if I had it turned around your method would work.
Ralph,
Believe it or not what you describe is what's known as a solid cotter. What I did is a split cotter. There's also a blind cotter. Your lathe might have one to keep the tailstock from moving when your using a center in it. Take a look. As a matter of fact take it apart and you'll see.
(Ok how many of you actually took your tailstock apart to see if I was right? Show of hands please. :wave: )
Bernd

Bernd,
It looks great!!
Where did that A-Round Tuit come from? I need about two dozen such buttons for all the unfinished projects that I have/ ::)
I have already taken my tail stock apart in the past, so you did not get me today. :D
Regards,
Fred
