Mark,
I congratulate you on your Grasshopper build.
For various reasons, despite being a reader of ME for a long time and a member of this forum, also for a long time, and having made a great deal of swarf, I have never built an engine! If I had, my first choice would have been a Grasshopper; I still have an envelope of drawings for one in my filing 'system'.
You refer to the 'Elmer's Grasshopper', ought I to know about the 'Elmer' part of the description? How many variations are there on the Grasshopper theme?
In Southampton, there used to be a chain ferry across the River Itchen, just downstream of where the Itchen Bridge is now. When the ferry was taken out of service, its Grasshopper engine was removed and, the last time I heard, was preserved in one of Southampton City Council's cavernous store-rooms. I left Southampton in year 2000 so I am not up-to-date but I believe, in pre-lockdown times, that engine could be viewed by arrangement?
Best regards,
Swarf, Mostly!
