Nice bike. Any progress on the engine?
An engineer at heart but not in practice, yet.

Hi Guys.
Sorry it's been awhile but I did say this was a long term project, I should have retired last April but carried on working so progress on Agnes has not improved. I am dropping down to working only three days this coming April, so should have more time in the workshop.

Anyway just to prove I have actually done something, here is the crosshead assembly which I finished last night. For scale it is approx 55mm wide.

That's looking good, a similar cotter arrangement to what is on my Fowler, are the rod ends and socket also tapered?

Hi Phil,
It's good to see progress on Agnes. That crosshead is a substantial bit of kit!

When I was approaching retirement (2014!) I first went down to 4 days a week, then 3. I still have some involvement with work, but I really don't have time to do much. As I think you will find out, we don't really have time to go to work, there are just too many other important things to do, in my case helping our daughter raise her one-year-old daughter on her own, among a bunch of other lower priority tasks.

I have a new set of bits to describe on the Throp Corliss build so I'd better get over there and write.

That is a great looking crosshead. It's a testament to the quality of your work that it stands up proudly to very close-up photography! :ThumbsUp:

Thanks for the kind comments guys.

I find I do a better job if I concentrate on one small sub assembly at a time rather than the whole engine, I have used that principle on the flywheel, the barring engine, the governor, the eccentrics and now the crosshead.

I am just pondering what to choose next, I might have a crack at the fish bellied con rod.
