BUILD DAY 105
The propeller arrived on time and has been loosely fitted to the shaft. My first impression was that they took a casting of Mickey's ears to get the blade shape and the second was how thick and blunt the blades are. The propeller on Caxton has edges that are finer/sharper by comparison but have no dinks or chips in spite of that, so the material is obviously fit for purpose.
A 22" compensated prop
When I arrived Stuart had gone shopping AGAIN. He must be the Emelda Marcos of boat fitters.
Richard was making a mock-up of the dining table to figure out how to position the support mechanism.
Peter was wiring the DC panel. Unfortunately this is a bit of a pinch point and as the side hatches have cramps on the frames, it is the route through the boat. He seems to be able to cope well with all and sundry wanting to get past.
The window looking out onto the tug deck loosely fitted (ignore the c**p on the deck and in the reflection) and admire the carpentry.
I don't understand a lot of the vocabulary, but Yarwood is actually starting to look like a boat!
ReplyDeleteDon't understand the vocabulary, surely not. Thee of Apropos, segue etc.?
ReplyDeletePersonally I think narrowboats out of the water look like oversized horse troughs. Mind you unladen work boats look like horse troughs even when in the water.
OK, now I have a bunch of prop-related questions!
ReplyDeleteBut first, a non-prop question: what species of wood is it that I see being used to trim the openings? It is beautiful.
OK, now the prop. Eolian's prop looks just like Yarwood's new one. But it is a 20 x 14, meaning that it is designed to absorb less horsepower, I suppose. Eolian's power plant is one you are sure to recognize, since it was made on your side of the Atlantic: a Perkins 4-236, rated at about 75 HP. How many horsepower do you have in Yarwood to drive that 22 incher? And what is its pitch?

Hi Bob
ReplyDeleteThe timber being used to trim Yarwood is Sapele, 'poor man's mahogany'. I certainly recognise Perkins engines
a. they were fitted to the double decker buses i learnt to drive in many years ago and
b. the Perkins plant is in Peterborough where we have a house.
As for the prop, it has a 20 degree pitch with wider blades, i.e. compensated. The John Deere engine is a three litre low revving beastie so this prop should shift a goodly volume of water which will aid the water skiing along the Thames...

Oooh when will you be coming to water-ski down the Thames - cant wait!
