Hi guys.
Here is drawings of a capstan for a merchant vessel 300 tons 1796 ish.
From my book on Investigator (in progress)
I may help in your builds.

Kind regards
Allan.

Hello Allan, long time no see.

Thanks for posting this
I studied this drawing and have two questions. The legend shows #20, carlings, but I cannot find them identified on the drawing.
Also there is a part #29 that is one thing in one drawing, the group making up the partners, and something totally different, a ring, in the next drawing. Is it the drawing or my old eyes?
Thanks for posting this. I am saving as it is great to see parts identified.

Hi Allan.
Thanks for spotting that.
And now for the excuses HA HA.
I have been copy and pasting legends from 1 diagram to the next and that can be a bit dangerous.
The feedback is most welcome.
Try this one.
Kind regards
Allan

Hello Allan, long time no see.

Hi Bryian. Yes I am still here. Working on Investigator plans and book. I have revised my planking booklet with more diagrams etc which is available on Amazon. I won't post it here because someone uploaded it to a sight like Alamy. If anyone has purchased the previous edition PM me.
Kind regards Allan

Great drawing.
I find this tidbit interesting ( of recent readings)
Its was not like we see in the movies raising an anchor back in the day… or close to modern Danforth / Navy Stockless.
Example It took a large portion of Victory 5 1/2 hours to get an anchor in and secured. .

Dear Allan, great work and thank you for sharing! Very much appreciated.

As I was programming Victory´s capstan this weekend, I had of course a closer look, to see any differences
The very base of both concepts is the same and your drawing well executed. Only for some scews/bolts I do have questions:

- The upper and lower chocks are srewed vertically with a gap in between. That would pull the chocks vertically up or down. If the chocks would go up resp. down to the drumhead resp. the base that the pawls sit in (is there the name missing in the legend?) without that gap than this would not occure. Alternatively the screwing/bolting should be horizontally and fixing the chocks towards the center spindle. I attached HMS Implacables capstan supposed to be from the 1820 and therefor a bit more trustable than Victory´s ones, as one is a 1920 replica and the other suffered plenty of repairs ;-) There one can see a horizontal bolting.
- 2 of these screws through the drumhead also go almost through the hand spike holes

Very nice details are the pawl pin and the retaining pins and chains for the handspikes. Bravo for that.
Any idea if this was a standard feature?

Hi Dafi.
The chocks are rebated into the whelps so they cannot be moved upwards or downwards by the clamping bolts.
The ratchet is item 12.
I originally had an outer rim on the ratchet but took it off to allow water to drain out, but I see in your photos that there are holes in it to achieve the same.
There would have been more bolts/screws horizontally in the whelps and chocks but I thought that was getting a bit pedantic. (too much detail)
I guess I will go back and add those to make it complete.
The pins to hold the pawls up are shown on this admiralty draught. (which is very similar to the photos)
On this draught the pawls are flipped over to sit on the pins. If you look closely this it appears that it uses 2 pawls only for either clockwise OR counter clockwise rotation. In the plan view you can see the pawls at 5oclock and 11oclock are engaged and flipped on the pins at 8 and 2 oclock.
The 4 pawls can be flipped over for free rotation.
Thanks heaps for the feedback and comments.
Regards
Allan
