I posted last week that I was having trouble getting my Nova 2 chuck back together. Well when all else try to find the directions.
I went to the Teknatool web sight and low and behold they had a wright up on disassembling and reassembling the chuck. The newer chuck I have has no numbers stamped on the chuck. But there is a "moon" shape milled into the chuck body where the #1 jaw slide goes. If you follow the directions it is a piece of cake to assemble the chuck. It's up and running again.
The manual that I have says to install the slides in !-2-3-4 order. There is noway it will go together that way. This on a Nova 2 that does not have the numbers on the chuck body.

This is interesting since both the original manual and the digital "Full Manual" on the Teknatool site state this:
"There is no dedicated starting slide way in the chuck, so you may choose any slide way to start from. Starting with Jawslide number 1 insert it into your chosen slide way, continue..."
The "Simple DIY Maintenance" manual on the same web site has the dimple info you mentioned. I found that I could in fact put the #1 jaw into any slot and as long as the others were inserted clockwise numerically the scroll fit and the chuck operated smoothly.
HOWEVER, if the #1 was not put into the original slot some jaws just did not quite fit perfectly when closed down all the way but left a small gap between two segments. I suspect this is due to manufacturing tolerances causing slight variation in the position of each slide slot. They probably discovered this and rather than correct the tooling they just marked the slide and assembled them all the same way.
Before taking the chuck apart I mark the original #1 position on the outside of the chuck body with an engraving tool.
