Re: Daily Fixing and Riding Diary on an Ariel 2019

Tracy Tools and Unithread sells left hand drills. Whit such ones it is easy to get broken studs out. Drill into it, and suddenly the heat from the drill loosens it.

Re: Channel Motorcycle

Our dear president, Ariel Atzori, intend to do that again. This time on Lake Como during the Italian Ariel Rally. He will do it on May the 4th. The vehicle has already been tested.
I would like to be there, but don't think, I can afford to go there.

Re: '58 SQ4 REBUILD

The Thunderbird carburator and the Square Four one is not quite the same, but I'm not aware of the difference. Some one here will tell you.
