Welcome Back Cotter!
I picked up an inexpensive Raleigh built Glider frame today with the intention of a quick tidy up, bearing repack etc. I've got another former student looking for some cheap transportation and have some spare wheels etc to put it on the road for $60.00 or so.
Sadly, I've encountered the most stubborn cotter pin in the history of mankind! Even George's vintage cotter pin press would not make it budge!
I 'll try again tomorrow but may just, leave it or replace the spindle and arm, we'll see....
