COMPASS, PRISMATIC, Mk3 (by Peter Laidler)

[Peter Laidler]

They are VERY nice too. Tough and reliable, they'll take a lot of hard knocks. I'd just suggest that everyone get a pair, so long as they're complete. Even if they just stay in the chest

Thanks for that and the other complimentary comments. Someone did contact me to the effect that he made a simple evacuation/depression chamber in a screw-top jar by evacuating it and retaining the vacuum by using a vacuum pump that formed part of a polythene food bag evacuation and sealing system.

Ok if you're doing a load of them but methylated spirit is better for the run-of-the-mill single compass.
