Discovered this channel a few months ago. I just finished watching the Haven 12 1/2 series of videos. This has got to be the finest built Haven in existence. Amazing attention to detail and masterful execution. I’m hoping the build videos resume soon continue to the launch date.
Hi Gary,
I’m happy you’ve enjoyed the Haven build. The tender I’m building for @acorntoarabella will be launched in June. I’ll then be back on the Haven and get her launched this sailing season.
Thanks for watching !
Bob
Good call on the ash for the tiller, it's the second best wood for handles behind hickory. And hickory's probably overkill for it, you'd need it for stuff like axes and hammers.
Great videos, I always have questions but if I hold them they’re always answered
I like to watch various youtube channels making boats, but as I do not intent making them myself whatsoever, I normally skip the talking-only part of their video. However, that doesn't apply to you Mr. Emser, even your talking are so soothing that glue me to the each episode from the beginning to the end without getting bored at all.
I have really taken to your motto. At work when I am completing a map, I think to myself, if you’re going to make it, make it beautiful.
Okay it was just a thought but at the beginning of the video I'm like what he do go to bed bath and beyond and get a towel bar 🤣 like I said it was just a thought obviously one of us isn't a boat builder (me) thanks for sharing.
Always enjoyable watching cheers...rr Normandy, Fra.
Love the title picture. Captain Bob!
“Some of you may have noticed.” Every time I had a question, the answer followed almost immediately. I remembered hollow ground screw drivers from my father’s boat shop, but I never knew the proper terminology. Thanks for the video.
Using a hollow ground bit for the brace & bit is also good advice
Fantastic video. I love watching you working with just the clock ticking in the background.
Bob....most enjoyable! The casting is entriging. Have you ever thought of using a Vixbit to drill your holes in the countersunk holes in the bronze. The Vixbit is self centering and you can adjust the depth so there aren't any OOOOPSIES.
I am always amazed by how many skills you have, but the thing I am most impressed with about your channel is that you get things finished. Keep up the great work
Thank you!!
Fantastic ! I'm always surprised by the fact that every little detail, piece, tool, has been planned a long time before the actual work. THIS is how you show us the way to reach the initial goal. Keep the magic going on, thanks a lot, Bob ! Can't wait for your next episode !
(Sorry if my english is a bit wrong, I'm french…)
The great attention to details makes this channel a joy to watch. Thanks for that.
Did you consider the tension that the traveler rod is going to be exposed to from the sheets?
I did no notice if you put threads on it or perhaps through bolt it to make it stay in place. Not nice if it comes flying out of there if there is a gust of wind.
That's Awsome!!! Thanks for your videos, very inspiring for me.
Beautiful craftsmanship brings a smile to my weary face. Thanks for these videos.
As always, an enviable excess of whimsy. This boat is a treasure.
I've been tracking this project for a good while now and I try and incorporate make it beautiful into all of my work now. It's helped me to step up my work even though I'm still very much a beginner. A beautiful job on all of it and I appreciate when you take time to explain things. Thanks so much.
Great episode!
With a surprise casting?! Most excellent!
Amazing work, Bob! Really beautiful pieces! 😃
And I totally agree with you about that color! It looks great there!
Stay safe there with your family! 🖖😊
I'm just wondering how long that black paint will stick to the varnish coated primer?
Casually casting bronze in your workshop is pretty mind blowing and amazing. What a wonderful set up you have! 👍🏻😊
A true craftsman
Piece of art
What a Master!!!! Every surgeon has to learn from you!
Beautiful work on the tiller and the traveler Bob. This is truly a work of art. Thank you for sharing.
Great explanation on hollow ground screw drivers.
To me, learning how they work was one of the most transformative moments.
Thanks, Bob. Another great episode!
An absolute delight to watch your precision and skills at work🧐
It's like watching a master professor at work.
Thanks Lou!
Thanks Bob excellent work on the hawse. Amazing casting skills. Thanks
Another interesting episode, from the sound your spoke shave made when shaping the tiller that ash is some tough and durable timber.
Good ears! Yes, very hard wood. Ash is at 1320, on the Janka scale for wood hardness, it falls in the middle of Red Oak at 1290 and White Oak at 1360
Thanks for watching and listening!
From the sound it is not only hard, but he hit some reversing grain too.
I like the preemptive strikes against we (us?) annoying woodworkers ready to pounce on why you cut the ash the way you did and why you didn't hand drive the screws. Hat tip.
Truly beautiful work Bob. The Art of Boat Building is supplemented by the Art of Staying In Shape During Retirement having fun making beautiful things. That is some serious work you put in to everything. Thanks for sharing!
Wow! You really lived up to your channel title with this one. You covered all the bases, wood, casting, etc. Love it... I've been waiting for a few years, but what's the next boat? ; )
Chapman makes the best hollow ground screwdriver kits. I have a few Chapman brand kits and have never had a failure once using them. Chapman btw is the inventor of the hollow ground screw and nut fastening. I have a couple kits that were my great grandfathers and I use them almost daily still.
Bob, You are amazing! The boat is looking fantastic!
Spec-tac-u-lar!
You my friend are a very talented man. A true craftsman and teacher. We need more people in this world like you.
Thank you Adam!
Gotta love getting to the boat jewelry. 😁
Always make it beautiful! You’re remarkable!
It was great to watch you make the pattern out of wood and then cast the part.
I tried something a bit different- I redrew all of the bronze parts in Fusion 360- then 3D printed all of the patterns. I then cast the parts using the traditional sand method.
I like the idea of melding the old and new technology.
Hey, wood turned or 3D printed, either one, then painted with Dupli-color plastic coat paint makes for a great negative. Six of one/ half a dozen of the other.
A releasable negative form is a form. Thanks for sharing your alternative mold making idea. If you have a 3D printed, that is certainly an option.
An interesting discussion of the screw driver tip. When you were cutting out the tiller, I was surprised that you were apparently wasting so much of the board. A few moments later, you explained why. It was almost like standing in the shop with you, and asking questions as you worked. One question you did not automatically answer was why you did not use a router on the corners of the tiller. I assume you were concerned that the spinning bit would have a tendency to to tear out tiny chunks of that hard oak, which would be the very devil to sand smooth later. I'm really enjoying your videos, especially the casting work.
Bob, I really enjoy your work! But...., was surprised you did not polish the traveler mounts, or am i jumping the gun? Such a fine piece of furniture needs it? Also, I to live in Illinois , near Wisconsin border. Be thankful, because, if i were closer I would be that 61 year old kid "holding the flashlight" for you.. better yet, paying tuition to the master teacher!
Thank you for sharing your art!
Hi Jim,
Honestly, I run out of time to get the video posted. I may polish it later, I do however, like the satin finish. In the end once the boat is in the elements it will turn brown. Yes, I could keep it polished but I hope you would agree "Sailor" Jim that I would rather be sailing than polishing!
You are always welcome to come for a visit being that you are just a couple of hours away.
Thanks for watching!
Cheers,
Bob
Best channel! Cheers for you from Brazil!
Great channel and a great boat. Surprised you didn't elect to laminate the tiller.
Ahh, but it is a laminated tiller, he just let nature do the lamination...aka... growth rings of the ash tree.
Looking fantastic. As always exceptional craftsmanship.
Best!
Beautiful work there Bob. She is looking very very nice
Looks incredible Bob love your dedication to doing excellent craffsmanship!! looks really good. Love the simplicity of your design as well.
Amazing Work!
Thank you Bob!
Beautiful job Bob!
Thanks again Bob
37 k subs. That's quite a jump since last I checked. 👍
Nicely done!
Question Please, why won't you trace the tiler pattern on the ash to the curve of the rings of the ash and not against it. Wouldn't it make the tiler stronger? I'm not a boat builder, but enjoy your videos very much thank you. LOL You answered my question in the video, I was a bit enthusiastic with my question, out of sheer enjoyment. 😀
Bonjour from France : parfait ,cordialement
Hello, I always follow your videos and I congratulate you on the quality and handling of the different construction techniques. I am interested in knowing how long and how much your boat weighs. Thanks
The boat is 16 feet overall length. The finished dry weight should be around 1400 pounds.
When using those very soft bronze screws, I suggest using a steel screw first to cut the threads in the wood before installing the bronze screws.
Hi Rick, Thanks for the suggestion. However, when the proper tapered bit is used and the screw waxed a steel screw is not necessary.
Thanks for watching!
Bob
Awesome job again
I'm curious, Ash is a fantastic wood for a tiler, it also steam bends beautifully and would allow you to maintain straight grain which is always best for strength. What made you to decide band saw to timber?
My thoughts exactly. Would make for a much stronger tiller, which is such a vital component.
Hi David,
I sawed the tiller because that was what was needed given the timber I was given. As I showed, the section I cut out was almost perfectly quarter sawn. As I'm sure you are aware that quarter sawn wood is at its strongest. The annual ring of my Ash run perfectly straight down the tiller length. The best way to retain wood strength when steam bending is to start with quarter sawn. Steam bent wood needs to have the annual ring bending with the curve for optimal strength.
Given the dimension of my Ash timber, it was not thick enough to be the right size for the tiller. Both have the same strength. Sawn is what I did given the material I had to work with.
Thanks for watching!
Cheers,
Bob
We use those in gunsmithing.
Nice work!
Beautiful.
Excellent!
Congratulations! What nice things you did! Could you make a 10 meter sailboat? Would you be willing to make a cost estimate in approx. Congratulations! Greetings from GREECE!!!
Another important point about screw drivers is that they wear out. A worn out screw driver tip doesn’t fit the slot well, and has rounded edges. That makes it highly likely to slip and marr your work. Screw drivers often have a texture that further prevents slipping. The older the screw driver, the more wear to that texture.
That looked really hard for Steve there (not understating the rest of it)
Absolutely fantastic Bob. I always learn something. Super episode. Your traveler is a bit different from mine. My rod bend 90 degrees into the mounts. I like yours better. When I tack, I can wind up with the block sort of stuck around the bend if that makes sense. Yours is a better design
Hi Chuck,
I saw that in you video. I assume that is what Jim sent you. I was curious why he sent that design I was just following Joel's plans. You are always welcome to come cast some if you ever want to replace it.
Cheers,
Bob
@@TheArtofBoatBuilding Thanks Bob, I may take you up on that. I think what Jim does is more trad Herreshoff. I've seen the bent rod style on the H 12 1/2
@@JenkinsBoatWorks ah that makes sense.
Master!
Beautifull indeed☺
Dear Sir,
I wonder if a straight piece, bent to shape, would make a sturdier tiller. The fact that the grain crosses a section of the tiller could make it weaker? I know this is good wood, but the question just crossed me mind.
Thanks and cheers from Brazil!
The quarter sawn ash has the grain running perfectly straight the length of tiller this makes it not have any cross grain and extremely strong.
Thanks for watching!
Cheers
Good job 👍👍
If that bar gets pulled hard in the center it may bend and pop out of those sockets. Have you considered soldering that rod into the sockets?
Hi Michael,
No, I haven't and won't solder the ends on for a couple of reasons. First, is that the holes in the bronze ends are nearly 3/4" deep and are a very tight fit.(so tight it won't spin) So I'm not concerned about it popping out. Second, if in some strange event that the bar did get bent it would be an easy fix to just replace the bar. However, if it was soldered in it would be a very difficult to fix if not impossible.
Thanks for watching!
👍👌👏
Beautiful and very inspiring! Is that a yellow or red type brass? Do you buy as ingot? Also, I’m surprised you don’t seem to have a tool room lathe??
Hi Gavin,
I’m glad you enjoyed the video. It is silicon bronze. It does come in ingots. I however purchased mine from a local university’s art department. (Scrape from student work) I’d love to have a metal lathe someday. For now I’ll just borrow my friend Steve’s.
Thanks for watching
Cheers,
Bob
Love your rudder cheeks, Bob. Where the bolt connects the tiller to the cheeks would the nut typically be drilled and installed with safety wire?
Yeah, I would consider a safety tether on the bolt and nut, I have a tendency to drop things. But if you keep spares, no need, I guess.
I was also VERY worried about vibration loosening of your hardware😟 Would you ever use Loctite?
The auto mechanic in me wants to use red thread locker on the acorn nut of the tiller bolt. I am now wondering why slotted screw drivers generally have tapered heads as opposed to hollow ground.
I get that! The tiller does has to be remove in order to remove the rudder which one would want to do when trailering. I'm with you on the tapered heads. Does make a standard screwdriver have somewhat of a multi-tool function I suppose!
As to the thread locker, that was answered. As to the screwdriver tips being tapered instead of hollowground as an industry standard?... It is cheaper in the manufacturing process to taper grind, so that is a shortcut manufacturers do it that way to save time and money in the process. Hollowgrinding takes a more complex and more expensive setup and more time and manpower to inspect that the grind is centered on the shaft than beveled/tapered grind does. Machines can check tapered grind much easier than hollow.
It's a money thing.
Just curious ,when making the pattern do you ever glue two pieces of wood with paper in-between so you can split in two rather than cut it apart?
Another great option and suggestion. I've seen this used for "inside-out" turning as well.
Maybe I missed you explaining this in one of the episodes, but why are you casting pieces like this that could be pretty easily turned on a lathe? strength? don't have a metal lathe? less material waste?
Hi Ben,
Interesting question. Turning metal on a lathe its much different than wood. Metal lathe tools are held rigidly in a tool post and only take off 1000's of an inch at a time. One must start with the general shape and then a small surface can be milled off.
If one wanted to start with a solid piece it would first need to be round. So to make the end piece one would need a 2" diameter silicon bronze billet ($288.70)
www.onlinemetals.com/en/buy/bronze/2-silicon-bronze-round-bar-655-h04/pid/7825?variant=7825_12_0&gclid=CjwKCAiAvaGRBhBlEiwAiY-yMGlDH-3HIST_dr7zUpLsu70F_H27kQWKX57zuQdjrPOAK9ClDjz2jhoCUqQQAvD_BwE
And it would take days to reduce it to the final size.
The 2 cast end pieces weighted less than 1 pound combined (I paid $6.50 per pound)
So turning the ends on a lathe would be highly impractical considering the time and material cost.
Thanks for watching!
Bob
It looks like a Spitfire wingtip on the wall at the back..........?
Good eyes! Yes, they are parts from a sculpture exhibition I did in Chicago about 10 years ago. Here is a link:
www.bobemser.com/Gallery.asp?GalleryID=124235&AKey=5K235NVB
Could you cut a strait piece and steam bend it into the final shape of the Tiller?
Yes, if one did not have access to a wide board as I did it could be steam bent from a more narrow piece of timber to the proper curve.
Tell me about screws. Why do you use slotted screws as opposed to Phillips…
At the beginning of this episode 42 I explain 'Why Slotted Screws?" here is a link ua-cam.com/video/0GVdUPDrfEA/v-deo.html
you could have gotten two pr three tillares out of that rare and beautifle piece of ash
Why not use steam bend the tiller into shape?
I have done that. Not sure why I didn't this time.
Why not use a laminated tiller with straight grain to improve strength and reduce material waste?
A laminated tiller would not be stronger than quarter sawn Ash.(1320 Janka hardness) I had very little waste and used the off cuts on other projects.
I was looking for video on the manufacture of your tiller. Which episode would that be? thanks!
Hi Ted,
This is the tiller video. Are you were referring to the rudder? That would be S2-E60 ua-cam.com/video/ADKGsOJDfO0/v-deo.html
What does the Traveler do?
Allows the block for the main sheet to “travel “ as one tacks
Is traveller another word for a horse?
@@BigRedNZ1 I had a brass horse on my first sailing dinghy when I was learning to sail.
No not in reference to a sailboat. However, General Robert E. Lee's most famous horse during the Civil War was named "Traveller".
