Making the axels and trial fitting the rollers.
Drilling the support and fitting the brackets.
Assembly complete and ready for riveting up.

Excellent work Rob, but do you think we can get it mounted onto one of the models?
I was thinking of putting it into one of my fortifications and then daring anyone to attack it. At that scale one hit, one ex ship.:happy:
Rob.
If you can get a cannon up a Mountain, you can get a ball up 100 feet. My suggestion would be a load of smallet cannon balls and use it like a giant shotgun al a Giant grape, but not bagged. Only take a couple of hours to load that lot!
Rob.:wink:
A busy day today.
After dooing the weeks shopping I got down to finishing the traversing cradle.
First I cut down the rivets and then rivetted up the other end to the wheel supports.
Next I positioned and drilled the fastenings for fixing the frame to the mainCarronade platform
Finally I tapped up the bolts through the frame and also glued and cramped the two together, leaving them to go off tonight.
Beautiful work, Rob.
Helpful notes on "magnetic basing": #6 steel washers are the right size for a small two-decker's entire length, or the ends of a 74/80. 3/16" work for the middle section of large two-deckers, or the full length of correctly-scaled three-deckers. No idea what I'll need for frigates and smaller--the idea here is one washer each at extreme bow/stern, and one each just ahead/behind where the pin would be on an Ares ship. Corresponding rare-earth magnets go straight down the centerline of the base.
I would say that with rare earth magnets, One fore and aft should suffice DB. If you find that insufficient yor can always add another amidships if needed.

This morning I have made a template for the preventer on the Breeching rope cable.
Progress has gone on at a fair pace today.
Filing to shape the two preventer brackets and squaring off the pins to immitate bolt heads.
Next I drilled the fittings holes in the slider, and fitted both brackets adding their rings as I went.
That left me free to glue up the gunport at the front of the slide base.
Tomorrow I will be able to start work on completing the Carronade Barrel.
The deck would be underneath everything Dobbs.
You can see the set up on HMS Victory. Only difference is that Victory's block is painted black.
Thanks Dobbs.
Remember I have had 37 years to consider it and I still can,t work out how I am going to produce those blocks for the running out of the gun.

When I needed a set of large blocks, I built them up from layers of model aircraft plywood. My thought was that, with the line led, you couldn't see the sheaves anyway, so why bother?
If you need pointers on reeving the line, I can give you input there.
Great idea Dobbs.
That may save a bit of work.
I will try and source a bit of model plywood.
Rob.
Meanwhile, here is what I have been up to today.Having retrieved the base from the cramp, I set up the pivots for the Carronade lug to fit between.
Next I filed a flat on the Carronade Breech to accommodate the lug for the Breeching rope.
Here is the lug being roughed out, and after this I taped a template of the shape of the lug to the blank and drilled out the hole.
I am now filing up the outer profile of the lug. This is where I got to this evening and the lug having a first fit.
Rob.
Did carronades have gunlocks? It seems like they came about after gunlocks.
Not sure at what time they came in for Carronades, but this is purported to be a model for one.
Rob.
Just found this Dobbs.

How fascinating! It looks like that one is mounted over the touch hole. I thought that they were in addition to the touch hole. I imagine that they must have been an option. I think I read that some folks thought them to have a negative impact on aiming.
Some new data on Spanish 74's I've been chewing on... Bahama was rebuilt up to a 74 in 1788, after the first 2-3 Ildefonsos hit water. We need an Ildefonso draught (not the crappy one Greenwich has as a storeship) to compare the Greenwich drawings and dimensions on Bahama to.
The best I could find was this information on Three Decks DB.
You probably already know this though.

Nice work, Rob!
I think you will find that it is mounted on a block at the side of the touchhole Dobbs. I suspect that the sparks are directed sideways onto the primed touchole so that in the event of failure a match can be applied to the priming. This again is only conjecture on my part and we would need to see the lock from the other side to be sure.
Rob.
Thanks again Jonas.

I'm more inclined to trust the measurements from Winfield on both--the key piece is profile drawings; as I've said before if you compare a Strike Eagle, a Tomcat and a Flanker they're all twin-engine, twin-tail, two-seat deltas of similar size and layout and yet the dimensions don't tell the full story of their radically different variations on that same basic theme. I know that if I were the Master Shipwright at Cadiz-Carraca tasked with bulking a 64 up into a 74, I'd want to use an existing blueprint rather than re-invent the wheel, and similarly if I was the Admiralty ordering such rebuild I'd want it done to the current "fleet standard" design so as to maximize commonality fleetwide.
BWAS 1793-1817
LGD's - Bahama 53.34, Ildefonso 53.35 (ARS Bahama at Threedecks 52.93)
Beam - Bahama 14.64, Ildefonso 14.64 (ARS Bahama at Threedecks 14.21)
BM - Bahama 1786, Ildefonso 1751
Implication: Either the ThreeDecks entry has her dimensions as a 64 (she'd be a damn big one; the last British 64's were a full 4m shorter, and the San Fulgencios that were the end of the 64 worldwide 2m!) or she was measured post-refit--major structural alterations seem unlikely for a ship destined to only serve as a prison hulk, so my suspicion is that the Spanish measurements were "as first planned" and that the Ildefonso design was substituted between that point and saws-to-wood.
I agree that much more can be learned from drawings than just from the stats as DB wrote.
Those stats are very much telling a strange story. I don't believe that they would elongate the keel though. It would probably have been almost as big of a job as to build a new ship from the timber of the old one.
The French did exactly that with the 1776 rebuild of Sphinx--tore down the old ship and reassembled its timbers to match the 1765 Artesien design, and several older 1740s 74's were done similarly to he design of 1760s Citoyen to make up the rest of her class. My gut is we had a full "Breakup and Reassemble" there... Spanish naval records are frustratingly incomplete even for the folks that DO speak the language, and very little of that work has been translated for the benefit of us who either do not or are decades out of practice.
Then again, I have a friend who's with Army Corps of Engineers, and even though G.'s heritage is Mexican rather than Castilian Spanish and his military service was Army rather than Navy, he might be able to help me muddle through it. I owe him a shoot session sometime anyway... that might be a good time to float the idea, if we can ever synch schedules.
