Yeah, the best page I have seen about the Time Pencils. I had the chance to buy three complet boxes of these pencils and as they are not my field I took them for resell, but after have in hands the tins I just resold one, (an extra black), and put the other two with my UK stuff. It is the problem of to be a collector.

cutaway of time pencil
put a nail or small screw driver through the inspection hole to hold the lower brass body in place, leave the safety stripe in the btrass body just in case..... Take a small narrow plier, place it just above the joint between copper part and brass part and turn the upper copper part a little left and right, this will loosen up the hole type crimp. Then pull the upper copper piece off, it will come apart together with the spring loaded striker assembly.
After separation, loose up the top hex which holds the spring loaded striker wire to take off the striker with wire and spring, take out the glass vial.
At last, try to loosen up the primer assembly from the brass tube ( you might have to drill out the stake markings with a small drill bit.
The rest is cutaway!!

Thanks for the pics I have managed to strip the pencil with your advice! that is a great way to un-crimp!! But i would prefer to cut 2x slots into the body like this one (see pic) also with it cut like this could you re cock the pencil??
what would be the best and neatest way??
Thanks

Yes you can reload the pencil but you better cut of a couple of the spring coils, to ease the pressure as the copper tube is considerable weakened due to removed section. It is very likely to collapse so be very careful.
I did it in a milling machine.

Cutaway time pencil
Hi Chase
One thing i found out was go slow. Very easy to damage the copper end.
I thought about using a dremel but decided against it.
Using a milling machine as Anders says is the nice and clean but if you don't have access to one try by hand. The one in the picture is done by the following:
Find out where the steel wire will go through the time pencil and mark it on the outside as a centre line as i guess you want to show the wire infront of the glass vile. Take it apart again.
I started by drilling a hole with a pin vice and a 1mm drill at each end of where the slot should be (see pic) Go gradually up in drill size until the hole is the same width as the slot you want. (Be careful to stop the drill before it damages the inside of the tube on the other side) Mark between the outer edges of the holes and with repeated scoring with a scalpel with a new fresh blade, you should cut through the copper tube fine. Use a rod to support the copper tube from the inside so that it doesn't deform while cutting.
The body was cut in the same way but used a razor saw for the cuts between the holes. The other thing i did was to make up a fake spring in copper so that there was no real pressure on the wire but it looks compressed.
Hope this helps.
Good luck and don't rush it!
All the best

Yeah, looks great. I always cry when see an ordnance item cutted, but nice anyway.
