Looks good, and a credit to you with basic tooling used

Veritas LA blockie......my favourite plane in my workshop.

Thanks for the kind comments guys. If i learned anything it is not to wear a rubber glove whilst planing as i have skinned my palm from repetitive strokes with the blockie. I think it's a cool little project to develop those invisible joins and general hand plane technique. I'd hate to think how much wood goes into a 24 inch bass drum as they are roughly 24-25mm thick up to 1 1/2 inches thick in some odd cases. There's alot of talk on drummers forums of people making 1.5 inch thick stave drums and the common "THE THICKER THE BETTER". I have chosen to ignore this forum advice and have it finish up at about 20-21 mm.

Good point Markus but It's a far quicker alternative for me than doing and rechecking a whole bunch of equations and relying on the accuracy of a really old beat up table saw angle guide (i just set the angle to 6 degrees and checked the blade angle and used a test piece to confirm that it was roughly 6 degrees with a ruler). It's probably more of a tool to confirm the accuracy as it can't be much less accurate than using a ruler. I should be able to make it all fit together when each block is carved down from [40 tapering to 35] to [37.42 tapering to 32.48] as I stupidly followed the instructions of a youtube video word for word and ended up making the blocks bigger (better than making them smaller i guess).

Rob I have an old Makita Circular Saw set in a Triton work Bench (MK3) and am going to make a router bench at some stage out of some old kitchen cupboard top material. By the way this video is by far the coolest way of routing the middle to correct thickness once the curvature of the outside has been established. Alot of people use Lathes for both the outside and inside but this router jig looks to be an absolute ripper:

Only real disadvantage is it really relies on your outside being very accurate

Could you use a pantograph if you were going to be very very harsh on accuracy?

Well, this means that your beat up table saw is not that bad.
My point was that if your digital angle finder measures with an accuracy of +/- 0.05° with a bit of bad luck you may be off as much as you are right now with your table saw guide. Hence my suggestion that, unless you are very lucky (which of course I wish you) in the end you most probably still will need to "dial in" the jig angle, regardless of if or at which point you will use the digital precision angle finder. But I would get this angle finder anyway, it seems to make measuring angles really easy and will speed up certain tasks. At no time I meant to suggest not to use it. Just that expectations are probably above it's possibilities.

good point indeed. I guess it's one of those things I'd rather believe It wasn't accurate as strange as that sounds. It is a very awkward/ scary table saw and things get stuck very easily while operating it. Dad has made his own adjustments to it to correct the feed issues by bolting a block of wood to the fence so that the wooden block does not extend all the way along the fence. Meaning you really have to watch how much pressure you put on both ends of your workpiece to ensure that you don't cut it on an angle/ cut a bow into it.

Rub plenty of candle wax on the fence and table. It will help the feed issue no ends...if you don't need to push hard to do the cut there is less chance of causing an error, or worse, an accident.

Cheers

Nice. Looking forward to seeing how you turn that shell down to final thickness.

Great little thickness jig
