Bob Cleek got a reaction from thibaultron in Need some help deciding which files/rasps/etc I need.
Roger, I've got a set of those very same spokeshaves. They're lovely. The sort of tool that just makes you feel good using them. I have the three spokeshaves in their original box. (They come up on eBay occasionally. Their no longer made, as far as I know.) I don't have the aluminum plate you have pictured above. It looks shop-made. What's it for?

Bob Cleek got a reaction from Canute in What is CA glue and how does it work?
Excellent point! It may seem redundant when building and glue bonds are young, but it really pays off over the long haul when parts and pieces don't start falling off five or ten years later!

Up thru the hull planking stage, we are building in different worlds, POF vs POB.
A frame that is overlapping timbers is mainly subject to sheer forces while being shaped.
The same while being planked.
For deck components being knocked in a lateral direction seems more likely than their being levered up.
For planking itself, I see at least two possible stress sources. If a plank is not pre-bent to sit on the hull, if it has to be held down until the bond cures to keep it from going back horizontal, it will pull up on the bond forever (noemal stress). If it has been bent thru the thick dimension instead of being spilled, It will exert a lateral force (sheer) and a twist (normal) even if it has been pre-bent and is a push fit at assembly. Nature never sleeps.
I think it was Underhill, that imprinted this at my beginning of this, but the belt and suspenders philosophy ( chemical and mechanical bonds for as much as possible ) but it has stuck like an obsession.

Bob Cleek got a reaction from mtaylor in Topsail schooner sail plans and rigging
While he latter rigging arrangement requires less line, the former is by far the more mechanically efficient. The boom being rigid, in the latter arrangement, half or more of your energy is simply pushing the boom against the mast, as with a bowstring and an arrow. I can't imagine why anybody would rig a topping lift in that manner.
There may be some confusion in interpreting some drawings, as "a sheave near the aft end of the boom and back to tackle near the mast" is very common, but the line through the sheave is actually the outhaul for the sail on that boom, not the topping lift.
I also noted in passing that you describe "foot ropes" (plural) on the end of the main boom and a notation on the drawing as "footropes P&S." Why would one ever need two foot ropes, one on the port side of the boom and the other on the starboard side of the boom? Both would hang beneath the boom. What would be the purpose of that? Boom foot ropes are not used all that much, compared to yard foot ropes. On the boom, they may on occasion be used when bending the mainsail or to pass a gasket around the loose canvas at the clew of a reefed main, but that's about it.

Bob Cleek got a reaction from mtaylor in Sutton Hoo Anglo-Saxon ship burial - footage of 1939 excavation
I'm always amused by the custom of those times that the men so often wore white shirts, neckties, and coats when they did manual labor. Sometimes they wore shop aprons, but always the shirts and ties.

If I remember correctly, the work foreman wore a brown "lab" coat and hat- flat cap or bowler to differentiate himself from the simple worker

CA adhesive is the Devil's spittle! It's hot and sticky, and there's always a high price to pay for using it in the end!

It's sure a beautiful piece of machining.

Bob Cleek got a reaction from mtaylor in Making and using a draw plate
How about something like a quarter inch down to 1/64th, or wherever the small Byrnes drawplate begins? That would allow for more than just trunnels. Spars could be sized as well and then tapered as needed.

Bob Cleek got a reaction from Meriadoc Brandybuck in Topsail schooner sail plans and rigging
My guess is that there's a fair amount of flexion in a boom of that length, particularly because it's a solid round spar, rather than a glued up box girder. Comparing the two photos, it appears to have much less arc when under sail, as the sail holds the boom up along the foot. You can see when she's under sail that the arc is the result of the tension on the mid-boom mainsail sheeting tackle. In the photo of her alongside, you see more arc because the boom is only held up by the topping lift and the gaff boom appears to be laying on top of the main boom to boot.

Bob Cleek got a reaction from mtaylor in Coffee sticks for planks?
I've used tongue depressors for frames which can be bought in bulk cheaply at craft stores. I cut them at angles to cover the frame templates and glued them up with PVA one on top of the other with the joints staggered, then cut them to shape on the scroll saw. They worked fine.

Bob Cleek got a reaction from Archi in 2021 NRG CONFERENCE
One of these days, you might consider San Diego. They've good a great maritime museum with real sailing ships, the Miniature Engineering Craftsmanship Museum nearby, which is on my "bucket list," and the fleshpots of Tijuana, which are only 25 minutes away! Sailors just love San Diego!
See: https://www.craftsmanshipmuseum.com/ (Affilliated with Sherline Co.)
These are fully operational working miniatures! The Duesenberg is 1:6 scale and made of over 6,000 parts. The engine is true to scale and runs just as the original on gasoline hitting on all twelve cylinders!

So, what sizes would you like the holes to be if I made a new one
