With absolutely no apologies to County Chemicals.
Just a reminder that a little dab of very heavy grease is an excellent way to hold small parts together while assembling them. (Don't actually use Brylcreem obviously)
I had to completely disassemble my CZ 452 and there is a little ball bearing at the end of the sear spring. It is impossible to hold the bearing in place, slide the sear in and push in the drift pin. Even if you have four hands this type of assembly is impossible without a little help. By putting a little bit of very heavy grease, wax or silicon grease on the end of the spring, the ball bearing "sticks" to the spring and the whole assembly becomes a piece of cake.
Just thought some of you could file this away for future use.
