Nova Pen Plus Jaws

[sschering]

I noticed the other day that the Pen plus jaw set I have is numbered 1 and 4
If I were to mount them on the numbered jaws they would be right next to each other.

Do the stamped position numbers matter for the Pen plus jaws?

 

[robersonjr]

Yes, and the # 1 and #4 would be next to each other.

So...somebody has a 2-3 set and can't figure out why the center drilling is off??? :>)

Yeah that is a problem I guess. Not much I can do about it now since I've had them for 2 years and didn't notice till now.

Thats odd as the nova website pictures them opposite each other.

 

[greenacres2]

Not really all that odd Bobby. Vast majority of their jaws are 4 piece and cut from a single billet so they'll align correctly. The pen jaws, being just a pair it isn't necessary to get a close minimum fit, so the numbering doesn't matter--but they must be cut from billets that are numbered anyway. I'm not taking mine off to check!!

I found the alignment to be slightly adjustable using the mounting screws and running them together before tightening.

Mine aren't numbered and truthfully I see no reason why it would matter with only the 2 jaws.

This is the method they recommend for all thier jaws. I make it a habit also to keep the screws a little loose, run the jaws all the way in and then tighten.

I believe they have to be opposing numbers because of the way the scroll part matches.


Call Nova and explain it to them.


I had a scroll body for a few years until I discovered the jaw carriers were too loose in the ways and the pen jaws would not clamp correctly.
They sent me a new scroll body at no charge.
