Folks,
Just to state the obvious, this is very much a jury rig, I wanted to check that three years work were not in vain!, hence the bodged fire hole door, drain cocks steam pipes etc. the flywheel is the start of a rope brake being made to test the engine proper, also there are no piston rings in yet.
went better than expected!
regards jack.

Hi Jack,
Understood.....Trust me I completely understand! I finished my engine long before I finished the boiler and it wasn't until recently I could actually test the engine at it's full design steam pressure!...I ran her first at an engine show on the steam table....with 50 psi.....not 150 psi...It was frustrating to not be able to put the screws to her on the prony brake.
Looks great Jack! What's it going into?

Dear Dave ,
There is a bit about what it's going into on page 1 entry 4 to this topic .
The hull in question is a Patricia hull moulded by Bossoms Boatyard on the Thames at Oxford . The original hull from which the mould was taken was made by Sam Saunders , I think in 1910, as an electric launch . It has a tunnel stern and should draw about 20"
Saunders later moved to the Isle of Wight and eventually became the Saunders of Saunders Roe aircraft manufacturers. The quadruple skin sewn mahogany construction that he patented was the pre runner of marine plywood before waterproof glues were perfected and was very strong (but a nightmare to repair when damaged) There are , I think 4 surviving sewn hulls of which probably the best known is Consuta http://www.consuta.org.uk/
I hope this answers your query and is of interest .
All the best Edward.

At 32 feet she should go along quite nicely!
