[Largeformat] All about Packard shutters

Ok guys, 
Here is how I optimize a Packard Shutter.
Hose : Any good well supplied auto parts store has this. I my town I use a mom 
and pop 
store . They have a wide variety. I use up to 3/8 OD to be able to move alot of air 
through 
it. I can get speeds on a 5 1/2 inch packard approching 1/25 sec.  Thats really 
fast. On the 
other hand the large hose and a Stiff bulb allows control in pulling the piston back 
when 
doing long exposures. There is less drag. 
How to clean and optimize:
Take the piston out  and POLISH it w / Brasso till it looks like a mirror. Use 400 grit 
emory 
on the edges of the blades. Wire brush the Inside of the metal halves and paint 
them w/ a 
high gloss black paint. The outside w/ flatblack...
Spray the blades w/ lemon pledge  furniture polish . let sit 1/2 hr wipe off . 
Reassemble and 
use it .
