Hey Johnny,
I got the kit from woodcraft awhile back when my wife and i went on a short vacation. The kit contained only the detachable key chain kit. I used just the detachable key ring, the neck of the 30.06 is large enough to glue in a piece of 8 mm pencil tube. I just pushed the 8 mm tube in as far as it would go and then marked it and pulled it out and cut it off then glued it in the casing. The trick to get the nib to turn and retract the refill is to cut a piece of 7mm tube 3/4 of an inch long,then press the nib onto the tube then cut the refill to 2 and 3/4 inches long, then press in the tranny and be careful and check progress with the refill as not to press in the tranny too far. Then i cut a piece of 7mm tube 1 and 1/2 inches long and glued it in the top of the 8mm tube in the casing. Then press the key ring attachment into the 7mm tube. Then all you have to do is push the nib end with the tranny pressed in and there you have it. The 8mm tube is just large enough to let the 7mm tube turn inside it. Then you can turn the nib and retract the refill. DO NOT glue in the tub with the tranny in it, if you do it will not then turn. If you have questions, just let me know.
