1947 Hobbs of Barbican Clubweight Build and many other old builds

^ Look forward to seeing how you get on

I bought 55g of the palest shellac flakes I could find on ebay and mixed a 17lb cut. This means you dissolve (by ratio)17lb of shellac into 1 gallon of Meths.
In more practical terms this equates to 1g into 0.5ml
I think I was a bit heavy handed with the meths, so it was probably more like 30-35ml into the 55g batch.
I then used a paint brush to apply it
As I said before I was in a bit of a rush, and put on about 6 coats in one night, but I think you'd be better off applying one coat at a time, and leaving it overnight, maybe doing another coat the next morning and then recoat in the evening. 4 coats should do the trick, you can always ride the bike between coats to see whether you've got enough on.

By the way, the tape I had under mine was from the same batch of SABA, also supplied by Dave Marsh

Thanks Rik,
Will make sure it dries between coats!
