HI John many thanks for the full size dogs dodass im very pleased on this cheers sir an yes a few probs again but enough to stop tiger from sailin which was most annoyin but it could not be fixed up at the pond so had to bring her home to the dockyard for more rework but that blasted heat was what got me was it as hot where you were ?

as it was 31C an talk about a scorcher an yes will tell on here when i know about vid but i may not be online then as tomorrow ive got to take p/c up to hughes shop to have new norton security fitted on an if they cant do it due to the fact its all in the red my p/c may have to be sent away but when it comes back i'll try to get back on here if poss as they will wipe all my stuff off to clean up my p/c so fingers crossed i can just get it fitted an bring it home as its workin fairly well at the moment
ATB TO YOU BOTH

Was quite unbearable yesterday pm Chris, too hot and sweaty for me these days .
Stayed in the front of the house where it's cooler .
Must have been unpleasant for you lugging that build around .
Will wait for you to post when your up graded.

HI Andy now the motors drive shafts are smooth an no thread an the U/J just slides on an does up with a small allen scrub screw an really i should have ground a little bit off flat on the motor shaft but so far they are not slippin an where the thread is on the prop shafts as thats the reason i cant use metal U/J

as they have allen scrub srews on the motor end an on the prop shaft end so its no good as i dont want to damage the thread on the prop shaft if you see what i mean an yes when the prop shaft fitted into the U/J then it locks up with a lock nut so it cant come undone but i think the reason this happened is due to the heat heatin up the plastic U/J

an then the amount of tourge on the prop shaft from tryin to turn the big prop WITH WATER LOAD ON IT so the weakest link in the system which is the PLASTIC NYLON U/J JUST GAVE AWAY AN THE METAL PINS JUST CAME OUT an then a U/S prop an a bloomin another prob for me an lookin closely at the prop shaft it has slipped down the outer tube from the motor vibrations so im now in a while goin upstairs to have a look at fixin it but im goin to have to remove the big bronce prop an then keep a nut on the thread an then use a bit of wood layin it on the prop shaft an just gently tap it up the outer tube back to its orginele postion so i can rejion it up to the new U/J an the tighten it all up an yes Andy im pleased with Tiger but not the U/J failure as ive never had this prob before so a new prob to me an it may be the makers fault not makin it strong enough OH DEAR here i go again lol
an glad you like her on the water as i was pleased to see her go off like a shot so some probs fixed an another has arisin wonder what next will rear its ugly head Arrrccccccc
chreers ANDY for stoopin an havin a look see

Looks like failure under load to me, rather than a heat issue Chris. Could you perhaps get a mate to thread the end of a replacement metal UJ that would be going on the prop shaft? You would have the same arrangement then.

YOU could be right Tim as them big props under water load take some turning so well Tim i will ask around if anybody can do it for me but im not goin to buy them before i can find someone so these plastic ones will have to do for now cheers Tim for your thoughts on the subject

Bloody marvellous! Told you she’d be alright :thumb2: . Throwing a shaft on sea trials is nothing to be ashamed of.

Not if you're a RN ship built in a private dockyard ...:rolling:

Marvellous Chris, I think it's a win with a little hiccup. I bet you wanted to go into the lake with all that heat...bring your trunkies the next time. She looks lovely in the water and well worth all the work you put into her.

Cheers,
Wabble

Ooooo, quite right not jumping in the pond. (Not without sturdy foot ware. )
I bear the scars of doing exactly that some 60 years ago. Still makes me squirm just thinking about it.

 

[boatman]

HI all an today ive just started investigatein that universal jiont prob an firsly i have removed that U/J an had a close look at it an i see that to me the U/J is faulty as one of the brass pins that goes through it has no rivet top on it just flat an can be pulled through the plastic an lookin at the other pin which did not fail this pin has rivet heads on it so the pin wont pull through an it did not so i think that was part of the problem an the other problem i see today is to do with how much currant the motor was takin an the motor shaft is very stiff to turn so more currant drain an its a lot more harder to turn than the other 3 motors so im gonna order another motor to replace this bad one so then will give it another try wish me luck all as i'll need it had more probs on this ship than all the others put togeather Aaarrrccchhhhhhh

Chris, you could grind a small flat on the threaded part of the shaft and still be able to screw on a threaded joint.

Haven't you only just bought these Chris? If the motor shaft is stiff to turn then take it back for a replacement.

Pete

HI Pete TBH i dont really want to do that on the threaded shaft as they are bloomin exspensive about 20 pound ago an knowin my luck id proberly damage the shaft so i'll leave well alone

Pete

HI again i think if i remeber rightly it was ok but i think the stiff motor shaft is due to the universal jiont failure as it also broke the prop shaft steady mountin as well in there must have been a terrific touge on that shaft when it failed so damagein the motor an Pete the cost of retuning it will outlay the cost of the motor as it was only 9 quid an the hassle as i think the motor comes from abroad but thanks for the idea
cheers Sir

Apologies for missing this Chris, it's brilliant to see her on the water, a testament to the work you've put into her, glad that the only probs you've encountered are reasonably easy to fix , those metal universal joints will really help control the torque from the new motors..

well done buddy, well done indeed..throws a salute your way

Hi chris

the photos of her are great, she looks superb. i'm sure you must get a lot of appreciative comments when you sail her.
