Another glue commonly used for laminating and boat building is resorcinol. Wonderful stuff. If you need many different size of curves (like frames of a boat) you don't have to fabricate a full mold for each, you can draw the curves on a lofting floor and bolt down 90° angles on the lines at intervals for the clamps.
Hi rob great vid I presume you were using ply as it was readily available I didn't see in the vid but I'm guessing it was still slightly flexible when removed ( depending on what use it is going to be used for this could be a good thing or not) If you wanted a stiffer result use thinner real wood laminates from an old 2x4 cut in to 2mm thick strips with the grain all running in the same direction as the 90 degree ones in the ply aren't really doing a lot as there shear strength runs along the width of the piece it doesn't matter if they have to be joined end on end as long as the joints are spread evenly along its length (this is where thinner laminates and more of them comes in to play). as boat builders we use this form of construction all the time and it can be done in many different ways for many different uses if you want to read something on the subject the early forays in to this are covered in Herishofs book" boat building" for the best results though I would use thickened epoxy resin just thick enough to hold a peak (like egg whites when making meringue)although having said all that I'm sure there is a really good reason why your doing it the way your doing it and cant wait to see what it is your going to make next. All the best mate
For a curved shed roof you could also do the technique showed in the video "Gothic arch greenhouse build | Gluing up the arches | Busy Beaver". I don't know if I can post links here, so replace the part after "v=" in the url of any video on youtube with ZAXTYP8lnGw. You would need less material, and your roof would have less weight. The gaps also provide space to run electrical and water pipes through.
Nice project! Wondering how much spring back there was once released and the relative percentage it is to overall diameter. Thank you for any info that you can share.
Thank you for the courtesy of a reply and so timely. I'm considering molding some landing gear legs for an ultralight aircraft and simplicity for the homebuilder is a great concern. Everything that you did was superb!
was wondering what 's up with the "cold mold" in your latest posts. Cool! Bigger 3D (bigger areas ) projects can be done by vacuum forming f ...or whoever is interested.

Very cool, you have me wondering what your making now. I'm thinking a huge water wheel maybe?
all will be revealed mate - but I like the thinking there
@@ThinkingandTinkering close to the chest huh 😅
I like the use of the ratchet strap I use clamps all the way around when I do this method of forming. I just think that the clamps are more accurate.
I like clamps better too - but not that many folks need or want a lot of clamps - I know crazy crazy people lol

I used the same process for the stem ends on a cedar strip boat. Rub some parafin on the mold and it slips off perfect with no residue.
I have made boat stems this way too
A beautiful piece of work mate
Oh what you building mate?
Nice demonstration, thanks mate.
all will be revealed mate
@@ThinkingandTinkering and so it was! 😉
You must have the UK's best Man-shed lol
U seem fairly serious about this world domination talk. Can't wait to see the finished product👍
Big wheel keep on turning!
lol - nice video - shame about the song lol
Good day Robbert....Well you have certainly piqued my interest....In heaven's name what could you be up to now ....🤗🙄
all will be revealed mate lol
Pretty awesome indeed! 👏👏👏
I think so mate
Funny I'm just about to start cold moulding a cabin hatch for my small yacht. 6mm ply and epoxy in three layers. Try bending 18mm ply :)
Thanks for sharing that. I've not come across it before and I think I may find it very useful. Much appreciated.
Glad it was helpful!
If you are joining these end to end to make a circle.
Would you not feather the ends to overlap each piece ?
That's one big crossbow.
it would be mate
Now I can make a fancy work shed and not have to make a steam apparatus.
it would be an awesome shed!
@@ThinkingandTinkering yes it would I can see arched windows letting the natural light .

Or you can soak it in ammonia put a vacuum On it then compress it into any shape you want and let it dry and it will set that way.
Hi Rob,
Did you use a hand router or something to make the arc of the mold?
Cheers,
Mark

extra ordinarily little mate - there must have been some but to be honest not that I noticed

vacuum forming is certainly good mate but it helps to have a variety of techniques in your armoury
Very nice 👍🤓
Thank you! Cheers!
6 wood wheels for energy generation? 1, vertical axis wind turbine. 2, venturi wind turbine structure. 3, thermal siphon turbine tower. Ah the suspense is delicious!
Great, thanks! 👏
cheers mate
Wow this is like adding ten arrows to my bow , fantastic stuff , do you need a 2iC for planetary domination lol
Pretty neat 😎
I’m in awe mate really am , geodesic type Domey things springs to mind , wow and have 1000000x wow lol
I’m chopping 😂🤡😊
Brilliant 👏
cheers mate
Now that is slick
cheers mate
Caskamite you said.
OK, I think I can see what you're making here. With all the talk of world domination and doomsday, you're obviously making an ark. Cheers Noah!
Pinky do you know what we're going to do today? What brain? Today we're going to take over the world
evil laugh and hand rubbing follow lol
It's mould not mold!
Mould! 🥳
soder, solder - tomato tomaato - couldn't care less - lol
👍🙏👍
cheers mate
