How to Set up Molds and Transom Properly, S3-E9

In episode the proper way to set up molds and shape a transom is shown. In the continuing series of building a 9 foot tender for Steve Denette's boat Arabella, boat builder Bob Emser, sets up the mold stations for Victoria. Using reclaimed Honduras Mahogany the transom for the dinghy is shaped and installed on the strong back.

Somehow bob knows how to ratio just enough talking to sweet boat building action.

[@danoyes1]

Yes! As a Dory Builder who has tried my hand at videography this is a difficult thing to do... most of my videos are sawdust and shavings flying with no where near enough talking!

[@arctain1]

Not sure that’s exactly true…

[@dwel2928]

In the late 60's, when I was in college in northern Ohio, I was active in Sailing Club and we built a couple of DN iceboats one winter. Did almost all the work in an old horse barn using only hand tools. The college shops just helped us make the spars and the skate blades. Boy did those boats go fast! Flying over the ice heeled up on 2 skates was such a thrill.

[@rick91443]

Always enjoy watching and am a big fan of Acorn to Arabella. You're doing a great job...cheers...rr Normandy, Fra.

[@MCsCreations]

Amazing work, Bob! 😃 Looking forward to the next steps! Stay safe there with your family! 🖖😊

[@TheArtofBoatBuilding]

Thanks, you too!

[@cliffjamerson3107]

Thanks you are so thorough your vids make me better in my Craft striving to get to your level of professionalism

[@davidc6510]

Another great Art of Boat Building video production Bob. Thanks for sharing.

[@MidtownSkyport]

Starting to look like a boat! :)

[@TheArtofBoatBuilding]

Indeed! Thanks for watching.

[@fonhollohan2908]

Remember if you going to make it, make it perfect if you measuring yourself up to Bob's standard. He doesn't just make them beautiful he's make them perfect as far as I'm concerned. Sorry to blow up you bubble Bob but I just couldn't resist.

[@loftonharris5632]

The Haven is my favorite sailboat of all time but is well beyond my reach. No matter, your build is magnificent! Your work on Victoria is something I could do (so long as it would fit through my basement door. I’m about to get started but a week ago I broke my right collarbone and can’t even pick up a pencil! In a month or so this will hopefully change. Your video today got me through a pain filled Saturday and I thank you! Building a stripped plank sailing dinghy has been a dream made possible by you and Steve’s examples. Time to join your Patreon community! Lofton in Philadelphia.

[@billlambert2092]

I’m not clear why you didn’t pull the transom shape from the lofting?

[@TheArtofBoatBuilding]

Hi Bill, Because the transom is at an angle it would require a oblique projected view. This could be fraught with possibilities of errors. I found it easier and more accurate to project the actual faired lines to make the pattern. Thanks for watching! ob

[@rickestabrook4987]

Great episode Bob. I always learn something new. Thanks

[@LiftRanger]

Bob, your videos make 27 minutes pass like seconds. Outstanding work, so informative. Thank you!

[@TheArtofBoatBuilding]

Wow, thanks!

[@drop_dtuned6167]

This week, Steve at A to A feature the house top and spoke about the hatches/ companion way. So as you described the mold set ups, I had a fresh visual in my mind. Makes me wonder, did you and Steve coordinate this weeks episode?

[@TheArtofBoatBuilding]

Steve and I are in communication weekly on the project. Ultimately what appears in A2A video is up to Ben the editor. Actually a lucky coincidence for this week’s videos. Thanks for watching!

[@ObsessiveScientist]

Finally decide to become a patreon. Thanks! wonderful work and inspiration.

[@TheArtofBoatBuilding]

Awesome, thank you!

[@plainnpretty]

I’m looking forward to the iceboat thanks for sharing your work

[@kairadisch9955]

Hi Bob, great Video again - got that before and aft the line theme now much clearer. One Question: When you built the stern knee it looked like the fibres where way to parallel to one edge - the keel and not 45 degrees as I thought they have to run - am I wrong? Cheers Kai from Berlin Germany

[@TheArtofBoatBuilding]

The larger the boat the more important that that is. This stern post is small and out of Ash is a very hard wood It scores 1320 on the Janka hardness scale. It is deceptive in the video however, the select piece of Ash is plank quarter sawn so it is amazingly strong. Ash is prone to rot however, the stern post in this boat will be coated in epoxy.

[@michaelwilkinson2928]

Oh to have all those wonderful woodworking tools!

[@bumpkin52]

I love that rasp, but I have found it’s best to leather gloves when using it. If it slips these razor sharp teeth do a number soft skin.

[@TheArtofBoatBuilding]

It is a good one. Thanks for watching!

[@MobilMobil-kv5ke]

I’m curious about the sternpost. I wonder if it would be better to laminate a curved blank similar to the stem piece? The entire ash post has grain runout. Also, I noticed you didn’t install biscuits or wooden dowels when joining the stern planks. Once again I’m thinking about strength.

[@chetthejet3896]

I was wondering why no dowels or biscuits myself.

[@TheArtofBoatBuilding]

Solid ash is a very hard, durable wood. It scores 1320 on the Janka hardness scale - harder than oak. This was some old growth Ash that I was fortunate to get. It has very tight growth rings. It is much stronger that a laminated post would be and a lot less labor. Modern glues are stronger that most medium hardness woods like Mahogany. Once the small transom gets glued to the stern post, the planking, the aft deck/seat and the in-Wales knees I felt there was no need for pins or biscuits. Many time they are need to make sure the planks are in line during glue up. The Mahogany I had was extremely straight and flat. Thank for you question. Cheers, Bob

[@Sonnengott]

Hi Bob, very very nice work you doing there. Your craftman skills are as good as your explaining skills. But i have one question about the wood for the stem. In 25:04 it Looks like the grain at the end of the stempost is realy short. could that be a weak spot? The grain should follow the curve for Max. Strenght. Steve for example used knees he cut out of That treeroots to get the grain parallel to the curve. I Hope that make some sense. Greetings

[@TheArtofBoatBuilding]

I think you meant to say stern post? The stem on the boat is laminated oak. Assuming you meant stern post I think you're underestimating the strength of Ash. Solid ash is a very hard, durable wood. It scores 1320 on the Janka hardness scale - harder than oak. I was lucky to have an old growth timber that Is nearly quarter sawn with very close annual rings. The function of the stern post is for mounting rudder hardware and holding the transom at the proper angle. The transom is held firmly once the planking, aft seat, and in-wale knees are installed. Very little stress is put on the stern post. Steve did not use a grown knee on Arabelle's stern post. A grown knees are nice when you have them especially when visible. Thanks for watching! Bob

[@bigunone]

Surprised you didn't use biscuits or dowels to join planks together?

[@TheArtofBoatBuilding]

Modern glues are stronger that most medium hardness woods like Mahogany.

[@loftonharris5632]

@@TheArtofBoatBuilding. No need biscuits or dowels. As Bob said they are only used for alignment of boards during glue ups if the boards being glued are very long.

[@tsampadi]

I really enjoyed this video , which I watched because I am just going to start making a sailboat myself , and really felt fearful about the centreboard part of the process . I don’t any longer , wonderful demonstration and methodical approach , cheers thank you so much for that .

[@daviddickmeyer5231]

Nice to see the DN (Detroit News) class ice boat. I’ve had the pleasure of sail one of those and they are definitely a blast. I’ve been over 40 mph and those who are brave enough can sail them even faster. But I was much younger then! 😆

[@jamesedwardson605]

I have been watching your fine work before this Arabella project...but I am glad your putting your make on the whole thing...Keep up the good work...

[@TheArtofBoatBuilding]

Thanks!

[@conniedrumjr275]

Another great show, thanks

[@TheArtofBoatBuilding]

Glad you enjoyed it

[@markhgillett]

The DN iceboat comes from Detroit Newspaper. My dad ordered the plans but when we discovered the mast needed to be Sitka spruce that kind of killed the project. But it was fun imagining.

[@Beowulf-sd5gh]

Im impressed with the plywood patterning of the transom, hadn't thought aubout that. Its genius, no lofting needed.

[@kevinhall2266]

Truly enjoy watching your craftsmanship and listening to your thought process that goes into the building of a fine boat. Very interesting for sure.

[@TheArtofBoatBuilding]

Thank you very much!

[@tomtruesdale6901]

Outstanding work you are doing there Bob.

[@TheArtofBoatBuilding]

Thanks Tom!

[@maoribaca2655]

it mass seem that hes making slow progress, but in fact, he's speeding along at the pace of a zen master. never let master carpenters fool you, their movements are calculated and calm and never by accident. seriously Its always a pleasure.

[@OwenFromOhio]

Great progress Bob.... looks Great!!

[@kadrikayaclar5048]

I think the best videos on boat building are on this channel. I have not come across a better and step-by-step explanation in terms of both technical knowledge and practical applications. Many thanks, greetings from Turkey... 👏👏👏

[@donwilliams3626]

It was neat to see that you were able to make that transom a found wood project. A2A will have quite a few recycled and repurposed pieces to help make her whole.

[@bake162]

I’d be down for some iceboat related videos

[@mawe42]

Those iceboats are seriously fast, capable of well above 100 km/h!

[@TheArtofBoatBuilding]

I’m looking forward to see her go. Been a mild winter so no ice thickness yet. Steve and may need to take a trip to Minnesota!

[@rossfudd256]

It sounds like you are going to build the hull around the mid seat. Isn't it more typical to finish the hull pull it from the mold then add the seat?

[@TheArtofBoatBuilding]

Yes, that's correct. The tender will not have traditional frames to reduce weight . The aft, fore , and center bulkhead will be an important part of the structure. So, I decided to put them in before planking to ensure a quality fit.

[@brutusbarnabus8098]

What will the weight of this craft end up being? It needs to be easily launched and recovered.

[@TheArtofBoatBuilding]

As light as possible. I don’t have a way to calculate the weight at this time. Thanks for watching.

[@charlesmoore456]

What a great way to spend Saturday afternoon. Such a pleasure watching you work.

[@TheArtofBoatBuilding]

Wow, thank you!

[@gordonquickstad]

I appreciate the time and effort it takes to video and edit these interesting sessions! Your creativity at each step is informative.

[@billmeldrum2509]

Very interesting process Bob. 🇨🇦

[@glencrandall7051]

Another entertaining and educating episode. 👍👍Thank you for sharing. Have a great 2023 and stay safe.🙂🙂

[@TheArtofBoatBuilding]

Same to you Glen.

[@FrEdmundScott]

First!

[@hartwiggrunewaldt5102]

Dear Bob! Thanks for showing all these steps to build a nice, little tender. Your streams are very informative because they do not show only the art of craftsmanship, they also show the basics of technical construction. Thanks for that! But there is one question: What kind of material did you use for the stations in your mold?

[@TheArtofBoatBuilding]

Hi Hartwig, Thank you I'm glad you find the videos helpful. The station molds are made of 1/2" (12 cm) MDF. Thanks for watching! Bob

[@inventiveowl395]

"If you're gonna make it, make it beautiful." - remembered this today at work. Installing cables and pneumatic tubes in a chemical plant. I imagined how it would look if I was laid them without being intertwined so that all of them would be perfectly straight. But because I'm kinda young, I'm still fighting the fact that making something beautiful takes *a lot* more time than just doing it somehow... Though I do have some patience (making models, the longest one took almost 900hrs over the course of 1 year), I get bored with things quickly - or rather, my attention is so scattered that it bounces to another point of interest. I guess that focus will come with age and experience.. Until then, I'll probably keep making things... not as beautiful.

[@joecioe8566]

Love the old-world mahogany transom and your craftsmanship.

[@briangately8104]

A while back, biscuit joiners were popular. Did you consider biscuits for your edge connections on the transom?

[@coldspring624]

I do hope Steve is rewarded with smooth ice. It would be very interesting to see him run the ice boat.

[@TheArtofBoatBuilding]

Me Too!

[@roydaley3413]

👍

[@notatechie]

Man, I would really like to have a piece of Ash like that.

[@chetthejet3896]

I have a bed headboard of ash. Made it a number of years ago, wonderful wood to work with.

[@TheArtofBoatBuilding]

The Ash is some beautiful old growth stock that I was lucky to get. I also used it for the tiller on the Haven.

[@TR4zest]

Very enjoyable and interesting. I loved seeing that transom come together. "If you are going to make it, make it beautiful". Well said.
