How to make a Pair of Compass Dividers
HTML-код
- Опубликовано: 8 сен 2024
- In preparation for spiling the planking on the Haven I build a pair of compass dividers. In boat building there's a method called spiling and it is the process of determining the shape of a plank that goes on your boat. In order to do this you need a good pair of compass dividers. Those old-school compass dividers we all had in grammar school just isn't gonna cut it. So, I made a pair that is accurate and will lock in place. In this episode of tool making I'll show you how I made pair of compass dividers worthy of passing down to your heirs!

"If you are going to make it, make it Beautiful" you sure nailed that with this compass, that is a work of art in and of itself.
I believe I enjoy these tool making segments the most Bob. Thanks for sharing.
Sr you are an authentic craftsman of which few are left. Thank you for sharing your knowledge
OMG Bob. When I was studying next to you in the Paul Gartside WoodenBoat School course, I had no idea how accomplished you are in other arenas! I taught for thirty years, but surely not to your effectiveness. You have shown me how fun it is to make tools. I have a tool my dad made in shop class 80 years ago. You have prompted me to make clamps, compasses, and?
Bob, I must thank you for all your precious lessons. Many people are addicted to watchin series. My addiction is to watch The Art of Boat Building. My tiny shop (10 x 7,5 feet) is becoming tight to add more machines and jigs and being close to 70 I wonder if it is worth to start building a nice shed. Eventhough, I was able to build a 10'2" Acorn Dinghy, plans from Iain Oughtred, using my open garage to host it. Particularly your wonderful tools making classes will give me lots of good times when not being rowing and sailing. Thank you so much and all the best!
I’m too old to build a boat, but your videos are so full of woodworking details and expertise.
Nice example of "Form follows Function" there, Bob !
Heirloom design and build quality. Well done, sir.
Yet again I sat mesmerised as a piece of functional art is created before my eyes. Truly and honestly, made beyond beautiful. Made awesome.
I made one years ago and now I need to make another. That is much nicer and you inspire me to do more tool's,Thank you.
Lovely job. I have made some knives and a trailer for my boat. For marking out I spray white primer from an auto supply shop ( Halfords here in the UK ) on the work which does not easily wear off and a biro can be used for marking out; I have found this to be far more durable, easier to see than any other method and easily removed with a bit of sanding if necessary. I look forward to seeing the compasses in use vey soon.
I love the ingenuity and attention to detail. Nice work.
So glad you posted this as I have finished the angle gauge, the awl and the marking gauge.
Absolutely stunning work! It would be a great benefit to the novice woodworkers, like myself, to include drawing out the plan in your video. It's hard to tell if the radius piece is drawn with a compass from the center of the pivot point, or if it's a combination of two arcs from a french curve. The fair lines of the outside edges of the legs are really what sets this set of compass dividers apart from just being a useful shop made tool, to being a beautiful piece of heirloom art!!
Again Bob........at the moment, I have no need for such a tool; but after watching your video, I want one!! Great job!! DD
Beautiful!
You make very professional looking, practical and easy and clear instructions . I really love your tool making videos
Thank you! Happy you like them.
Meraviglioso, bravo!
Another beautiful tool Bob. Thanks for sharing!
Vous êtes le Maître , Bob .
Saudações fraternais! A arte transmite a beleza do conhecimento e a vontade de ensinar! Muito obrigado por dividir seu conhecimento! Parabéns por sua arte!
Obrigado pelo seu gentil comentário. E obrigado por assistir!
That is quite the compass divider tool. Amazing Bob. Probably could double as a weapon as well, in case you has an intruder in the studio. 😀
I can only say: "Wow!"
Wedge? Did you mean to say Wenge? If not that's not a wood I'm familiar with...but I'm always ready to try a new specie 👍Either way that's a beautiful compass, thank you for sharing your process with us!
You are correct. Thanks,
Hi Bob, It certainly looks like Wenge to me, a south-central african timber that is very dense and beautiful to turn. Watch the splinters though, they go in and crumble. Regardless, a beautiful build and fantastic end result. I wouldn’t have thought you shaped the metal part with drills and files. Goes to show how a lot of sweat can take you a long way.
So cool 😎
It is simply beautiful! Well done and thanks for sharing!
Thank you! Cheers!
Un petit chef d'oeuvre ce compas !!!! Magnifique travail !
A small masterpiece this compass !!!! Beautiful work !
Always enjoy watching...cheers...rr Normandy, Fra.
Sir, your videos are excellent and your craft is a pleasure to to behold.
A real master!
Thanks !
Thank you, great video
Excellent job a tool to treasure and pass down, so much better than shop bought 👍
Beautiful tools
Your shop is soooo clean! Thanks for a very nicely done presentation.
Great job!
Wonderful !
Very nice!
bueatiful work
inspiring
Hello,Bob!Your work as always is excellent!
Gran bel lavoro complimenti
Beautiful work! Thanks for sharing.
You did!
I’d buy one if offered for sale on your website. There can be a market for hand-made ones.
it is very beatiful, thank you for sharing with us.
As usual, beautiful tool. Nicely done.
Great content and fine craftsmanship.
ohhhh i love your channel !!!!!
Very nice job sir thank you
Nice Tool, thank you!
I would like to say that the screws that you were using to attach the brass sleeve were in fact number 8 screws 32 threads per inch. They could not be 8/32”. That would make them 1/4”
Correct, that is why in the caption text it is denoted as 8 dash 32 (8-32) not 8 slash 32 (8/32) which would denote a fraction. 8-32 in the nomenclature for a machine bolt or screw. I did not refer to them as a fraction of an inch.
Thanks for the clarification James some viewer may have been confused by that.
Very TACKFUL answer.
Just a thought but if you slipped a 3/16" piece of wood into the slot when drilling you wouldn't have had as much distension of the wood when using the forstner bit. Nice looking tool!
Nice!
I think the correct name of the wood you used is called Wenge not wedge on your Dividers . However regardless of the name of the wood they are a beautiful tool nice job !!!
Heirloom quality. Nice work! Engrave your name and date for when they get passed on to younger family members.
Nice! 👍👍👍👍👍👍
First time viewing your vid, very impressive work! Thanks for sharing the beautiful art.
I was wondering if in the building of your boats do you incorporate golden ratio in the build? If yes then you must have built a gr gauge before?
I do being an artist I really don't think about it. Just apart of my aesthetic now.
Вы молодец,лайк и подписка однозначно.Слежу за впшим каналом ,всё на высоте.Исполнение,подача материала.С уважением владимир.
Beautiful. A tenoning jig would have made cutting that slot safer.
They came out nice! If you want more subs, feel free to put a link to your video on our homemade tools forum; looks like you're one of us :-)
I can not find "wedge" - is it wenge? Sorry english is not my first lunguage
Yes, wenge please excuse my misspelling.
Never heard of "wedge" as a timber type before and google turns up nothing, do you have any more details please? *Edit* - Having now watched further into the video and seen close up shots of the wood in question, I'm pretty sure that it is Wenge. See www.wood-database.com/wenge/ for details and please feel free to correct me!
The closest i came is to "Wenge" ,it looks similar, but i dont knowm i couldent finde Wedge either, and i searched for it in "The wood database" www.wood-database.com/
Wenge is an ironwood like ipe. Very dense. I was thrown by the wedge comment as well because I thought I was looking at a wenge board when he first laid them out for consideration. Wonderful and beautiful work. I'm making me one very soon.
Bob what the dimensions of compass divider?
The dividers are 7” long.
Cheers,
Bob
I am wondering what kind of steel it was. It seems to be hardened (cause when grinding it, he was cooling it to not lose the temper) but soft enough to be easily drilled and filed.
Hi Peter, It was 1085 tool steel.
Thanks for watching!
Cheers,
Bob
@@TheArtofBoatBuilding But was it already hardened? because it seemed to work to easily for a hardened piece of steel. Not to mention you talk about cleaning off mill scale, which would suggest that it was not hardened. Did you misunderstand that the steel has no temper until it is hardened and then "Tempered". so you dipping it in water was doing nothing except keeping it cool enough to work with. unless i have missed something somewhere along the way?
what are the dimensions of the steel plate
3/16" x 3" x 9"
Any links for where you got the shapes from? I would also like to craft one
Wood is Wenge not Wedge. Nice work!
These designs are available where? New sub
I'm aware of their use for technical drawing but how do you use them when building boats?
Check out my current boat build and you'll see I'm working off of the technical drawings drawn by Joel White the designer of the Haven 12 1/2 that I am building.
Excellent build sir! Will you offer the drawing? Sub'd!

A nicely made tool, but do you feel comfortable using a grinder without the guard? I sure don't! And especially without full coverage safety glasses.
Well, if you don't feel comfortable using a grinder without a guard, then don't. Don't try to project your inadequacies on the way everyone else works. That's your issue to sort out, not everyone else's.
Screw and post... I always heard them referred to as sex bolts. Then we giggle.
