measurements for drilling holes for k conversion.

I need the measurement for where the cross pin goes across the back holding the trigger group in, and the measurement for where the pringle screw goes.

Thanks in advance!

converting a p-series to a k-series, right? no idea what the measurements are... i usually just put the trigger block partway in the back of the valve tube, draw a pair of crosshairs where it looks right, squint, stick my tongue out, and drill a pair of 1/8" holes, then angle them to align with each other... that being said, i think tymcneer was making drilling 'guides' to make doing this easier (i'm just too cheap to get one)... as for the pringle screw, i usually just use the nutsert...

One of the p68-sc I have is missing the nutsert. looks like it was ripped out. Also I don't want to drill any extra wholes in this stock I have. Its too nice.

But thanks, I'll probably just follow your guide though for the trigger group.

I don't have measurements offhand either. I would get the trigger group installed first. For the few I've done it's been the same process as chplnstone except it usually involves a bit of praying and occasional cussing. Then hold the body and stock together and mark the body through the hole in the stock.

so i broke out a tape measure and the action screw set hole in a k-series is centered at 2 7/8" from the back... on the downside, that measurement on a p-series drops it right into the valve core... so you're likely to need to drill another hole in the stock (or solder a length of 14"-20 rod coupling directly to the valve tube). other option: replace the nutsert with either a press-in one or use a 'nutsert ring'...

sheridan p-series to k-series conversion thoughts...

Maybe I could use the pringle screw and somehow seal it on the inside. some kind of gasket or something. Or maybe I'll have to bite the bullet and drill a new hole

I made an adapter to attach the nutsert to the stock hole. I did have to modify the stock on the inside but it is still usable as it was originally intended. I had a thread on it at one time but it seems to be gone.

Here is the first on I made

Here it is on the gun.

I don't have a picture of how much I had to route out of the inside of the stock for the adapter to fit.
Now I used a different trigger group but the hole in the stock for the pringle screw is in the same place.
