No idea Stave. Click the link and read it. This thread is essentially being used as an index to new ideas. If people choose to post those elsewhere I thing the discussion should also take place there.

I met Mike Nelson and Karen Tweed in a session last night. I know Mike as a Northumbrian pipe maker amongst other things, but he has all sorts of engineering skills I didn't know so much about. He and Karen are collaborating on improving the design of a piano accordion and he's documenting it all on his web site.

Despite being PA focused, much of it is relevant to melodeons too: reducing weight (of casing, bellows and reed blocks), making the action faster etc. Worth a look.

  his attempts to design lighter weight bass reedblocks as led him to a trianglular shape.  someone should mention the fact that the reed tips swing,and require some clearance within the reedblock.   a new mind can come up with many ideas ,which is great.there then as to be a process of testing ( mentally or physically) to weed out the real gems.
  reducing the weight makes sense ,and there are new materials to try.  we should remember that a lot of "classic"melodeons are made from materials chosen for low cost and ease of manufacture.
  making a one-off prototype with alternative composite type construction is one engineering challenge, but doing a production run at a competitive price,is another.
    I hope we shall see some positive results ,that will stimulate further thoughts on this topic.

That was the whole idea of this thread.   Materials science has made exceptional strides since the melodeon was invented.   More ideas please :|glug

Is there some good reason why you can't mount the reeds with the tips towards the fat edge of the block?

I was thinking that there would be, as often the valveless smaller reeds are inverted on the last two reeds on the block, I'm assuming that the others aren't for a good reason. Or is it just so the big reeds don't bash into those on the next block, as they are often closely mounted? I've had to have one of my treble blocks shaved at a better angle so that the blocks can tilt away from each other more for this reason.

That's one reason, tip clearance.  The blocks are closest at the bottom.   The second is access for tuning.   When the reed tips are upwards there is good access to the reeds for tuning.  Not so when the reeds point downwards.
