Servicing a 70s Mercury - Spring Choice

[piggy589]

With a Mercury or an Airsporter it's a great help to do a dry build without the mainspring.

Rigger gloves or bare hands,you'll know the point or angle at which the trigger block and action threads engage.

Add a burly mechanic friend and the job's a doddle .

Thats a great idea, wish i'd heard of it sooner. Took me about ten attempts to get the thread engaged last time I had my challenger apart, I was exhausted after & cursing bsa's .
