Re: Daily Fixing and Riding Diary on an Ariel 2019

Steve,

You should make a silent B&W film of your activities.

It would be a blockbuster :lol: :lol:

Re: Lathes

A friend-of-a-friend (Donald) has a small Garage business in Leith (North Edinburgh). He bought the premises 30 years ago at the same time as an Engineer (Ronnie) bought the place next door. These are 17th century buildings, one being initially a Cooperidge and the other a coach house for the Mayor ...
