Hi Stew, I really like your clamp you made with coach bolts and some wood to hold that boiler tube, it's something I'm going to be making soon, to hold some things I hadn't a good idea on how without marring them. Watching the sawing with that clamp in place looks like the tube is solidly held and with care, won't move and get grrrrd up. I noticed in your pictures of using the step drill for some of the holes, the "forward cutting angle" on that type of drill is essentially zero, which was what I was trying to describe in stoning off the leading edge of a regular drill bit, for copper and all its alloys. I really like that bit about drilling undersize, and turning a lip on the tube to hold it in place, that idea beats all the others I've ever tried, glad to hear a testimonial during a build!! Don't let paying work interfere too long, this build is far too interesting, so stay in the shop late, work hard, and get back to the project, you got that? This is your audience speaking :hammer: all kidding aside, great looking job, and fine craftsmanship, I'd like to see the whole of it when you've got it done. :jaw: :bow: mad jack

:D :D :D :D :D

Nice one Dave

Thanks Jack

I'm pleased the wood clamp will help, its amazing what you can pick up on forums like this you're drill edge stoning for copper is filed away for further use, some times all it takes is a picture for bells to start ringing and ideas to start to form. :proj:

Dave:- I thinks its called a Greater Gullable Goat :)

OK went on the hunt to B&Q (great big hardware store) for some Thermalite/Celcon blocks (Autoclaved Aerated Concrete (AAC)) picked up four half price 50p each as they were damaged, but for my use as a hearth that won't matter.

This afternoon I've made a lid for the tank

Still got to put a lock on it just to keep the contents safe away from animals and children

I spotted a oblong bucket at B&Q for keeping paint in for roller application looked just the right size to fit in the tank and take the boiler.

The acid will be in the bucket and the tank will act as a second skin containing accidental leaks and splashes.

You're really getting on, Stew. I always like your projects.
What will you use for the pickle? I mean, what kind of acid?
