As I'm now starting to put the 49 back together. The valves and seats were pitted pretty bad so I had a friend grind them a couple of days ago and after cleaning the block and putting a coat of primer on it the valves were ready to lap.
I got to thinking that somewhere there was an article about valve lapping. I found it on Rudi's site. Mr. GW put together a great article about an easy way to lap the valves.
I used Mr. GW's method with one exception...I used 5/16" hex nuts super glued to the top of the valves and a 1/4" drive 1/2" socket to drive them. I did try to swage some washers but had trouble keeping them flat. You need to have a flat surface to sit on the valve for maximum surface area for the glue to bond.
The valves and guides now have a nice gray appearance and the time was minimal.
Sure beats the sucktion cup deal
I couldn't find mine anyway and didn't wan't to buy another.
So Thanks Mr. GW
