Using the pig inside and chucking from the outside is a lot easier than making a ring for the OD and chucking from within.

Blondihacks

Yah, that's my plan

Bruce Crichton

Is there a way to use your "Pig" as a mandrel or interior support in the chuck?

Peter W. Meek

That was my first thought as well.

hi. time well spend. Why not just use the aluminium part inside the part and the 3 jaw chuck? that way it wont deform?

Hydraulic fittings too- what a mess. Ten different standards that all look similar.

Ah the joys of mismatched thread sizes, it’s 10 times worse in Australia, as we have to deal with metric tapered pipe threads that impersonate their imperial cousins. Air fittings are an absolute nightmare.

Interesting point...probably need to clean with acetone after Brasso.

"bigstackD casting" (one of many salvage and ingot casting youtubers) has a pretty good video on polishing non-ferrous metals, although he may not worry about thinning the workpiece. I do question the use of Brasso before clearcoating, as I believe Brasso leaves a protective film behind which may react with the clearcoat.

I'm so glad you didn't give up and now look at it. looks great. can't wait to see it all put together and working.

Ahhhh, the joys of polishing brass 🤣 Start at 220 grit and work up to at least 1200, get all the lines going in one direction and with the next grit up go in another direction. This allows you to see where you are going. You may need to go up and down the grits at the 600ish stage. When you get to 1200 use a bit of 0000 steel wool in a circular motion, then on to brasso 👍 Love the look of that chimney 😍

Haha, "angry banding". I like that.

Emily Ellis

After your latest Lens video I got curious and went looking for brass banding, because you're right, that is the sort of thing you'd think McMaster would have. After an incident with search autocomplete, now I'm really stuck on the idea of using bandsaw blades as a structural element, because they're basically just angry banding.

Yep, it is for insulation, and that's what I'll be using it for as well. I did on my last boiler and it works well. Some people also put a layer of silicone or something underneath for addition insulation but the wood will be fine for me, I think

Richard Gardiner

It'll be good seeing the boiler with mahogany lagging. You'll need to be a bit more accurate than the "typical" 1/16 in. for the wood though! I assume wood cladding was used originally for insulation?

Rare bad things with extreme consequences require just as much attention as likely bad things that you just wish wouldn't happen. (Of course, likely bad things with extreme consequences should be eschewed entirely.)
