Tally Ho Capstan Project: Installing Ratchet Dogs on the Capstan Winch Drum 

One would think if it goes another hundred years, then those dog hold-off levers will have ends break off again, since the (failed) design was not modified... not thicker or wider.. Or were they a different material? I didn't catch that. But I suppose the dogs really won't ever be used, since they added electric drive. Heck after the first or second time they try to run the capstan motor with one or both pawl dogs in wrong position, they might just wire or epoxy them out of the way. Or use a pair of slip joint pliers tio unscrew and remove the dogs

​@@ssn608They lasted for a hundred years and yes. they will be used again. The capstan is now designed to be used manually and with a motor.

It probably already is installed. Leo asked weeks ago if anyone traveling from southern GA or FL to the PNW could pick it up. These videos are often not up-to-date and could show things from a month or more ago.

​@@snappingbear They didn't actually last for a hundred years... they were broken before the restoration processs began.... probably MANY years before Tally Ho was last put on the dry. And yes, I have followed the project and listened to this video, where he explicitlty says that the dogs would be lifted during electric operation. So presumably, the levers wouldn't see as much abuse as they did over the previous 100 years. However, having some knowledge of Human Factors Engineering.... when you have not one, but TWO pawls on opposite sides of a capstan, where they both may not be in easy view of the person operating the capstan, and multiple people (at different times)) operating the electric drive, no interlock preventing operation of the the electric motor without ensuring the pawls/dogs are in the proper position (I haven't heard about provision of an interlock, have you?)... how many days (weeks... maybe) do you think it will be before someone operates the capstan in a direction that is blocked by a pawl? And what will be the result... what will give (break) on the capstan; because if the capstan motor has enough torque to be useful to help warp in a boat of Tally Ho's considerable mass and wetted area to a dock or mooring buoy, and that motor is started with one or both pawls engaged to prevent rotation in the direction the motor is trying to rotate the capstan, I believe SOMETHING will break (hopefully a shear pin coupling the motor to the gearing). And after a couple of inconvenient and perhaps expensive repairs.... will the pawls and the locking lever still be installed and operable? I'm not sanguine about the length of time that the locking levers will remain operable.... they may be removed from the capstan along with the ratcheting pawls/dogs to prevent such problems in the future. And if they aren't installed, they aren't operable.

@@ssn608 If they have the motor fed through a motor starter hopefully it would trip before any damage in done. MS are designed to trip when the motor draws more current than normal.

Used a good variety of machines too.

I correctly imagined that it was a big job. BUT... the right people are working on it.

yes, it's been quite a journey to follow this project from pattern maker, to the foundry, and to the machinist.

Not brass. Aluminum Bronze. Its MUCH harder stuff.

@@Fullion-CA Still a poor choice.

Still mared up just the same...... 😠

some flats machined on it would have been nice.

LOL, same here. I could not believe it.

I was watch both of these guys separately, not know that they'd ever work together.

Most don't knows that Keith is also a highly skilled woodworker who makes furniture. You're only seeing half his shop, the other half is full of woodworking tools and machines.

Did you also grow up in Finland?? :^)

It’s interesting to note how many beautiful machines from that era are still out performing modern, made to a price, machines. Down side was I suspect the machinists of old were paid a pittance!

@@johnsherborne3245 Yes, Using old machines that work like new,

I thought he was going to use that boring mill for the Stoker Engine.

Or 'taper', 'second' and 'plug'. Not that it matters!

Same :)

I suspect that there will be a similar system that works the same way windows in cars stop when coming up against resistance.

@@Rog_Ramjet I hope so, perhaps a circuit breaker if the current is excessive or a mechanical clutch or shear pin in the drive.
