Well.....looks like I'll be stuck in the workshop for the forseeable future then!
Things are still being figured out, and it might take me a short while to get the basic designs right, but at least I know there's demand out there (I struggled to sell my first TDR ones).
As for those cans Wayne, I might be able to knock some up for you (they took almost as long to make as the chambers themselves)....if I can find some suitable metal that is. (the last ones were sourced from a scrap yard) give me yer email and I'll get back to you.
