Bamboo makes a perfect P-channel

Howdy doodies😁

I've just fired up my first RMH build. (Chuffed to bits)

It's quite small - 8cm × 8cm.

So, I made a P-channel (using an old stove shovel) but it was quite a bit too deep and I fumbled the re-cutting of it badly. It was too loose. Grrr.
 I gave up on it and settled down to lunch.

In an earlier post I asked some growies "what's the best wood for burning in a rocket mass heater" - and a great growie called Peter helped me realise my bamboo is far from useless but perfect.
Fast growing.usefull for all sorts of other stuff. Makes a fab windbreak and provides enough good food to keep  a pet panda.

Anyway- I threw in a bit of hollow bamboo and "WHOOSH"...ITS A NATURAL P-CHANNEL.

So instead of taking space and fiddling about trying to make another one I shall simply add a whole round bamboo section for each burn load. Job done.

Oh joy oh joy. I love this community.

Well Jo;  That's certainly being innovative!  I guess if it works to your satisfaction then its all smiles!  Good Job!

Awesome! 8x8 cm is even smaller than the burn tunnel in my glasshouse RMH, so you've done well. And that is definitely an innovative use of bamboo.
