Can't Set Sail

Postby Merlyn » Thu Mar 05, 2015 3:01 am

Not storm bound but info bound. Can't sail without these Tufnell bushes fitted. Someone must know answer? Can't believe the silence.

As I understand it, Tufnol is a trade name for a laminate built up from layers of woven linen cloth, impregnated with resin, to form a corrosion resistant block that can be machined to form bearing bushes for slow running shafts, particularly those running in Sea water. It used to be used in Sea Water pumps, as a replacement for Lignum Vitae staves on propeller shafts and to make propeller bushes as an alternative to running on staves, with Sea Water lubricated shafts. They became obsolete about 50 years ago when all the shipyards and shipowners went for oil lubricated shafts running in White metal bearings / bushes. In recent years there has been a revival in Water Lubricated Shafts, because of the huge fines that can be levied on ships with leaking Stern Tube seals. The preferred material now is "Orkot".

Good answer BP , there were 32 in total on each ship, driven by a central hub which had a cam attached to it? Two bushes in each rod running around the cam? But where did they live?

From the Vessel Pollution and Dangerous Chemicals Regulations (SOR/2012-69) respecting underwater components, eg stern tubes

5. For the purposes of section 187 of the Act and sections 7, 29, 67, 82, 95, 100 and 126, substances may be discharged, and for the purposes of subsection 109(1) and section 110.6, substances may be emitted, if

(c) the discharge is a minimal and unavoidable leakage of oil that occurs as a result of the operation of an underwater machinery component;

Section 187 of the Act (CSA 2001) says:

187. No person or vessel shall discharge a prescribed pollutant, except in accordance with the regulations made under this Part or a permit granted under Division 3 of Part 7 of the Canadian Environmental Protection Act, 1999.

Having turned the bushes they turn the other way when the ship goes astern? Two sets chain blocks / lift pulls required here to change these to prevent the crank taking charge? Will be claiming this decades Stomper medal at this rate.

Thanks for that but where are we to fit these bushes in order for the ship to set sail? You could not be present in this compartment when under way?

JK, Ought to tell you that the T word prolifically used is part of the big four? To strip one of the other T's requires at least four vernier type height gauges?

Are we talking feathering paddle wheels?

Keeripes Merlyn, I didn't realize you were 104!
I think even Transport Canada has gotten rid of the feathering paddlewheel question on the 2nds.
I was doing some head scratching on this one.

Was a yearly job on the paddlers, went on until 1966 when the last old feller went to the great scrapyard in the sky, Radius Rods about 12 feet long, bored approx 10 inches each end, Tufnell, as it was then, had to be replaced every year or before if the Paddler ran over dunnage or a floating railway type sleeper. They were coal fired ( before my time honestly) and later converted to oil. Used during WW2 over here, as tugs, tripping boats, cross channel,salvage among other usages. I have had a hard marine engineering life but I am not really 104 years old it's really just because I have had a hard life that I might appear that way? Having been done out of Martins Stomper of the decade medal I now move onto T.T.T.T.? Can this one be solved? Remember the vernier height gauges were in proper measurements ie inches, not Mickey Mouse jobbies, ie m.m. as we over here appear to be forced to adapt now.

We only have the one paddle boat here in Canada, out in BC. If it's still around.
I started on a up and downer steam ship built in '49. 3 scotch marine boilers , twin shafts, Skinner Uniflow engines. it was at the end of it's life. Most people are surprised that is where I started.

There's a paddle boat in Toronto harbour, takes passengers on jollytrips around the bay. She used to be a tug, I'm told.
