Somehow I missed this thread... Never mind...
You can use a Tick Stick, but I say you need a Jogglestick!
It's all in the fits...
It's all in the shape (and splitting hairs to some) but I say a Jogglestick has a far lower error margin. Use a Jogglestick correctly and there is zero confusion and room for error, when you transpose your template... but no allowance for stupidity. :grin
I tip my hat to @NorfolkNgood :bow, he works at the 'top end of town', whilst I am a humble boatbuilder with only 23 odd wooden boats under my belt, and none of those would probably even be considered as suitable tenders to those lofty folk.
However, I've built many a canoe, sailing trimaran, and various gunkholing craft...
As well as working on an incredibly diverse range of craft at our local Maritime Museum as a volunteer through our local Wooden Boat Association.
Even did a stint working at a local Epoxy Manufacturers (WEST Competitor) Factory, where I built several 'moulds' they then used to produce Production DIY Boat Kits, they are now selling. Done a bit with timber, glass, Kevlar, foam, vac-bagging, laminating in 59 varieties, resin infusion, strip planking, cold moulding, all that good stuff.
There's no money in building small wooden boats, so I renovate houses to pay my bills and fuel my passion, which is...
Build'n and mess'n about in small boats....
BTW what is the definition of a 'small boat'
Answer: It is a large hole in the water that you never stop pouring money into....
:tongue :big cheesy grin
