Saving Old Seagulls

The next will be shiny zinc plated, just making some experiments to find the correct mAmps

Oyster , great job on the photo and research . excellent .
minor error on the label of the photo I believe . you have labelled it 1/8 bsp . I think you would mean 1/4 bsp for the carb nut side .

Well spotted. Photo changed..

Lol I only mentioned it to prove some one reads your posts if some one used it to make an order or pass on incorrect information as gospel .
I only need one copper fuel line and one water line in copper so I'm going to make mine out of scrapped lines but I'm sure your information is invaluable to others . good job

If this helps

Wow that's impressive! I was wondering what the dimensions of the banjo were!

Banjo as well.

Howabout a crank?

Its not that easy to do you know.

Any use?
Early fifties. LS or 102. Only the cutout for the key was differently placed.

Yes not bad.

What is the diameter of the crankshaft where the bearings fit? Could it be 5/8"?

.6250=5/8

Now look at the size on the drawing and compare

The ID of the bearing is 5/8, the crankshaft is ground slightly smaller to provide oil clearance.

Please note that this crankshaft has a minimum clearance of 1 thou & a maximum of 1.25 thou.

This particular crank is one of the low balance versions that was only used for quite a short period.

I see. I am asking because I have found some 5/8" reamers
