  1. The boat I was referring to was a diy narrow boat. The tiller is heavy as the upright is rolled channel section. Plenty of weight but overall length of material from stock to hand is much less than you get on a "Z bar" It is heavy as the upright is a thick rolled channel section. Its just too rigid and transmits vibration badly. The extra length of bar you get using a "z bar" is going to be helpful not just because of the weight but also the actual change in vibration along the solid bar.
  2. Making the bar between rudder stock and steerer's hand longer will alter the vibration frequency transmitted to the steerer's hand. Probably making it less damaging to the hand over long hours. I know someone who thought it would be clever to use a non conventional tiller ie an upright part and a horizontal "tiller bar" and the boat is horrible to steer due to the vibration frequency at the end of the tiller bar. Just a theory.
  3. Fair point and you could well be right. It seems an odd location for a winch handle as it would get used as a step in that position. But could well be exactly what you suggest. Isn't that slot above it a lubrication point for a chain drive to the gearbox? Eta or is it a shaft
  4. The EA Thames do still have a barge with sewage tanks on it but its usually towed by their tug "Churn" and I think its a modern barge although I have never thought to check it out. Its wider that a narrow boat. Looks like it could be a footrest. Sitting on a tractor seat like that with no footrest is quite tiring (ask me how I know)
  5. It looks good I think it would be quite a swift boat.
  6. Used to be moored at Springwell LTM half way between springwell and stockers locks on GU. Wooden top looked a bit dodgy I always thought it would make a nice tug deconversion as it had original GUCCo stern and quite a nice bow with a double curve effect. Lister SR3 in there I think. Its not at springwell anymore. Not sure where its gone. Would make a lovely tug with alteration to back cabin and proper engine. I was told the bows were done by wfbco but no idea who told me that and Pete Harrison is likely to be more accurate!! To be fair Rugby is in Warwickshire
  7. Any suggestions as to where the water came from for all the downhill locks through London? That must have been some massive water demand with pairs of wide locks all the way down. Plus of course locks down toward Brentford. I reckon that big hole in the side of Cowley lock is related to the water demand for the canal not the mills.
  8. If it a smoke less fuel it will be listed here https://smokecontrol.defra.gov.uk/fuels.php Waste from smoke less fuels is not just ash from combustion.
  9. Good history lesson i see Frays river is a manmade diversion of the Colne https://en.m.wikipedia.org/wiki/Frays_River
  10. But why cowroast? The Colne doesn't join until below Lot Mead AFAIK. Surely for river Colne management you would be logging traffic from Common moor down or actually just do Lot Mead. I don't think the cut used any Colne water above there. Maybe it did. Then there's the Bulbourne and Gade feeders so not all the water coming down is from the reservoirs. I don't see a mill v canal problem on the Colne above Lot Mead unless I missed a bit further up.
  11. Surely it would be too complicated to control every boat using the canal. How would the lock keeper at Cowley know where the boats had come from in order to make the decision. Did he inspect each boat on arrival and decide what to do? The waterway beside Cowley lock is the Frays River which goes under the cut immediately above the lock. Its not the Colne. I always assumed that side sluice in the lock was a flood sluice but it would make more sense to put it above the lock. Or a feed to the long pound from the Frays River with lock empty and gates open. Definitely intriguing. I've heard people complaining that lock useage in London on Regents section causes level problems for the long pound so maybe that sluice was used to give an extra supply as well as the water which is provided by the Colne via the bywash at Uxbridge lock. But then most of that disappears just above Uxbridge boat centre. The fact the side sluice is no longer used could explain why the long pound goes low in modern times. Because there is inadequate supply. A direct connection to the Frays River would be undesirable because it could cause flooding problems in London. Having a controlled optional supply might be useful specially as there was probably more traffic density and all the locks are going down. And they were double locks so you would need a lot of water. I can't think where else the water to get through London is coming from. There must be another supply. I believe they had back pumps as well.
  12. Video of it on YouTube. Hand start... Voiceover by Jim MacDonald. A good moral in this story. Always cover vertical exhaust stacks with something heavy which will NOT blow off... Otherwise you could easily screw a nice engine from rain damage..
  13. Gardner six in Freddie I think its an L3. Eta No....Its a 6L2... Its not a nb its an ex PLA health launch built by Yarwood's.
