Reconditioned oil lines

[garand1944]

I offer this simply as how I polished the seats.....no right or wrong answer

I took a new #2 pencil and a small ball cutter on the dremel and put a tiny depression in the pencil eraser. I put some fine/liquid valve lapping compound on the seat and a used check ball. Dropped the ball in, put the pencil eraser on the ball and made like a boy scout going for the fire starting badge. Cleaned all up and installed the new springs/balls. The seat was polished sweet and no leaks.

I made my compound from a bar of brown "Tripoli" polish that would normally be applied to a buffing wheel. Lee Valley in Oakville/Burlington has the stuff @ about $5.00 a bar....Smoosh a bit it up and mix it with mineral spirits/varsol etc and add some oil...A thin runny mixture seems to work best.

Apply compound to the seat and use the lapping tool...You will hear it cutting for only about 1/2 second during the operation as the compound leaves the area of the ball/seat.. Then you must lift your tool to allow the compound to run back onto the seat (hence runny compound works best).

I finished up using Autosol polish. This might not need to be done though...

I used a tiny dab of JB Weld to secure the ball to the lapping stick..(takes overnight to cure though)

I bought a refurbished set from Darth. $100.00 + $18.00 for shipping. As Aldo Raine said, "damn good deal!".

I wandered away from home today and saw this post.
Just so ya all know, 12dot over at KTOG does the reconditioning of old lines ...

I do occasionally work on check valves and pumps though ...

I just didn't want to get credit for 12dots' efforts ...
