Steps in Fabricating Bronze Blocks, Part 2, S2-E75

[@drop_dtuned6167]

I really enjoyed your story about your grandfather and the lathe. It is amazing how the sense of smell is such a powerful memory trigger. Thanks for sharing the stories.

[@Rennrogue]

Scent memories of a grandfather... You win. My grandfather raised and butchered hogs. Thanks for another wonderful video! I always look forward to seeing what you make next!

[@lanesteele240]

Bob, you know dern well that we will watch you make the same block 30 times

[@GrahamPearce-ib9om]

And “If you are going to make it, make it beautiful” surely applies to these blocks.

[@horatiohornblower868]

You saved yourself a ton by making these blocks yourself, Bob. Splendid work once more!

[@Pete-z6e]

Bob, as a retired manufacturing Jeweller I’m able to compliment you on your attention to detail…make it beautiful !

[@TheArtofBoatBuilding]

Wow, thank you!

[@tomtruesdale6901]

That hardware is nothing short of art. Very well done Bob,

[@desertpoj]

I’m not in the market for a bronze block, but having seen your work and then looked at the price list they now seem good value!

[@eddybear771]

The more I see You working with home cast bronze, the more I want to learn about it. I do blacksmithing, & even create some of my own crucible steel, but have yet to rry casting. But I'm certain that I will be. Thanks Bob.

[@bobsails9750]

Thanks very much

[@davidc6510]

Wow Bob. I really enjoy watching you coax beautiful art out of basic materials. Another great episode and I must say sir - your parts are not beautiful - they are exquisite. Thanks for sharing. Cheers!

[@plakor6133]

Perfect, as usual. Those fittings look like fine jewelry.

[@mattevans-koch9353]

Those are some first class jewelry pieces for this lovely craft. Thank you Bob.

[@thedailydeary7787]

Beautiful craftsmanship!

[@Rsama60]

Perfect work as always. Those blocks look beatuful.

[@gerardvila4685]

Those glittering blocks remind me of a French folksong: The girls of La Rochelle Have built a ship To go privateering In the seas of the Levant The ropes are threads of gold and silver And the blocks are diamond The mainsail is lace And the foresail white satin (There's another verse that mentions the hull in red wood, very cleanly worked - sounds like Tally Ho's keel - but I've forgotten the rest.) The crew of the ship Are all 15 year old girls And the captain commanding them Is the king of good fellows (funny they taught that to school kids... we didn't quite get it at the time though)

[@bclare2544]

Nice work Bob.

[@terrybrower3437]

You comment on the amazing expense of finished bronze blocks and other hardware. Have you ever kept records of labor and materials of a total boat build for example the Haven. I'm guessing that would also be amazing!

[@jamesHadden-l6l]

the 12 1/2 is a great boat Know I probably will never get one But have wanted the H-28 for decades Great vid, as always

[@phildavis2544]

My Herreshoff 1938 12 ½ footer now has the jib sheet rigged a little differently. Instead of the jib sheet being fastened on the starboard foredeck there is an additional block mounted there. This allows you to run a longer jib sheet back along the starboard side to an additional cleat. Thus you can trim the jib from either side of the boat. This is really helpful when single handling and in strong winds where all of the crew is on the windward side. BTW this was a modification from the original setup.

[@TheArtofBoatBuilding]

Hi Phil, That's very interesting. I can see how it would help in strong winds. I'll keep it in mind for the future. Thanks for watching! Bob

[@michaelwilkinson2928]

Beautiful craftsmanship - having a superb set of workshop tools and equipment also helps!

[@toddwheeler1526]

Beautiful work sir. Just a suggestion. Run a tapered reamer about 1/4 of the way through the outside of your axle and pin holes prior to upsetting the pins. They will be secure against any unforseen forces and corrosion.

Simply awesome fabrications!!! Looking forward to seeing the sails too!

Nice work.

[@TheArtofBoatBuilding]

Thanks!

[@terrulian]

Amazing work.

[@robertbamford8266]

Forgot to ask if you will be stamping your mark into these? They really are art.

[@TheArtofBoatBuilding]

Hi Robert, No I won't be. The convex surface doesn't stamp well.🫤

[@markgallagher1376]

Beautiful blocks, Bob!! I was going to correct your F to C conversion too, but someone already did.

[@andrewseaman7012]

Hi Bob. Beautiful work! I wonder if you could increase the holding strength of the rivet heads by countersinking the axle borehole from the outside of the bronze part. That way the rivet heads material would expand into the groove on both sides of the bronze plates and firmly hold the plates together. If you hammer on the axle without creating an expansion space for the rivet head it will sure build up a lot of pressure inside the borehole and hold the plates together, but I'm afraid it might not hold up to the stress that may occur when sailing. Cheers, Andreas

[@TheArtofBoatBuilding]

Thanks Andreas, I won't be countersinking the hole. The pin is only a few thousands smaller that the hole. Very little peening is needed to close up that gap. Once peened it is impossible to remove them. The other reason is that I'm interested in the pin becoming almost invisible. By countersinking the gap will always show. Thanks for watching!

[@ned711]

Such fine craftsmanship! Thanks for sharing your excellent work with us.

[@glencrandall7051]

The bronze work is outstanding. Will it get some protection (lacquer) to keep it bright?🙂🙂

[@TheArtofBoatBuilding]

Hi Glen, I'll wax them and let them grow old gracefully. Thanks for you Loyal support! Cheers, Bob

[@rogerbraidwood7611]

Beautiful Job ...truly a work of Art !!!

[@skipbaker529]

Absolutely beautiful! Cheers!

[@DavePilotCH47]

Question, why wouldn’t you create a little rebate in the boom so the block could sit flat?

[@TheArtofBoatBuilding]

That would weaken the boom

[@baderal-zaidi2966]

Master Bob.

[@porkchop955]

Excellent work as always. Are you using a new camera? The video quality is superb.

[@TheArtofBoatBuilding]

Thanks, I switched from a fancy Camera to my iPhone several video back. Been paying more attention to locking the focus on tight shots. Thank for watching! Cheers, Bob

[@bobhargesheimer3514]

Bob - I was taught that when making a flush peen like you're using, to create a small counterbore. Is this overkill for most applications ? You do beautiful and imaginative work, and your patience has slowed me down in the shop and improved my game. Thanks

[@TheArtofBoatBuilding]

Hi Bob, Yes, creating a counterbore or counter sink is overkill and creates undesirable finish. One can never peen enough to fill the gap. Here is a video of a knife maker explaining how to peen pins. In it he uses a reamer. That is not needed when peening similar materials as I did. I turned to pins down to 3 thousands less than the hole. By peening I expanded the pin for a permanent fit. Here is the video: kzbin.info/www/bejne/n2mxqaqnlr-VrNE Thanks for watching! Bob

[@bobhargesheimer3514]

Thanks

[@howardmarshall5713]

I love how a good craftsman makes sure all slotted screws when tight are in line. Perfection. hats off to you Bob.🙂👍

[@SailingThruLife]

Hi Bob. Love your content. Not saying it won't be strong enough, but the two pins on the block that raises the gaff will need to resist a bending load. In other words, it could tend to rack while under load, possibly pinching the sheave. The pins on the other blocks will be symmetrically loaded in shear. Just wondering if you'd considered that.

[@TheArtofBoatBuilding]

Yes, that has been considered. The tensile strength of Silicon Bronze is 105-415 MPa that equals 15,229 - 60,1970.7 PSI. I very confident in their strength. Thanks for watching. Bob

[@nfisheremti]

psst -41F is -40.5C not -5C :) (the non fahrenheit people all think it's been 23F out and don't know why you're complaining)

Centigrader here! I was thinking -5c whoopdy doo, but -40 c …..brrrrrr.

[@kipeagan8543]

You are doing beautiful work as always but I'm curious as to why you didn't put a small countersink on each side of the blocks to upset the pin shanks into. By grinding the upsets off flush there is only friction holding the blocks together. Maybe you did and I just didn't see it.

[@unnamednoaddress.2343]

Your work is magnificent grandpa. What is your age and education? I have a degree in mechatronics and a nurse in Brazil.

[@jimlucier7968]

Great work on the cheek block but I noticed that when you fastened it to the mast you have the flat surface of the block on the curved surface of the mast. Would it be more secure to flatten the mast just under the block and bed the fitting to the mast? The spar flange looks to have a proper curve base to fit the mast.

[@TheArtofBoatBuilding]

Hi Jim, You maybe over thinking this. My design is quit normal. Here is a link to a Harken Cheek Block. It is the same size sheave for a 5/16" line. It is attached with 2 screws and is flat on the back. www.harken.com/en/shop/small-boat-classic/29-mm-cheek-bullet-block/ Thanks for watching! Cheers, Bob

[@WesW3187]

Not that I’m doubting you, but do you think that the shaving and polishing of the heads of the two little shafts might make them a little weak in terms of their security in the cheeks? They seem to be interference fits alone. I guess I’m wanting to know how you ensured they were strong enough. I love your work 😢.
