Very cool thread. Thankyou Gary and Esteve for doing and sharing all this. If I didn't already have a bunch of projects, I might get myself some of the sensors you are using and rig them up to my North 1K drum roaster. It runs on propane, where the gas exhaust does go through the beans and

Next time I clean a grinder will be the first time!

I think they'd be fine together. The basic angles work together. That said: When you're dropping $13K on an espresso machine and > $4K on a grinder, some hundreds for custom steel side panels for the grinder to match the Speedster seems a drop in the bucket if you don't like the wood

If people can enjoy a cup of coffee they normally couldn't due to health reasons; I would say thats a positive

It looks like BSP. If those first few threads are gacked you could tap with NPT, and use a conversion fitting, or tap it to the next size up BSP, there appears to be enough meat. Other option would be to braze or tig weld a new fitting to the outside
