I'm doing a steel smokebox again, as steel is what I have. I'll paint it internally this time.

Here's the marked-out front plate. Who else uses their digital calipers for scribing lines? :thumbup:

Hi Dave,
Do you use 16 gauge on this type of project?
Do you paint internally with gal?
Thanks Tim

It's 1.6mm Tim, I'll just use ordinary household oil based enamel. The last one wasn't coated with anything except steam oil for a year before I started coal firing

Starting off the smokebox door hole with a holesaw, the rest had to be bored out

When properly engineered, even the simplest of parts are a joy to look at. :)

They do Aaron :thumbup:

Here's the back plate from 4mm hot rolled steel. I wanted it thicker to engage better with the boiler shell. The profiles were scribed from the front plate. The hole will be a lot bigger

That's a big hole for the boiler barrel, turned in the lathe on a faceplate. I'm just sawing off the excess before grinding and filing to profile. I used the bench grinder, very satisfying. Lots of checking with the digital caliper to get the curve even

Very tidy - and a damn sight quicker than chain-drilling and filing! :oops:

Whatever it takes to get the job done :thumbup:

Checking the fit with the boiler barrel material, I bought that about 10 years ago from Macc Models, for this model :D

Turning down the bending radius for the smokebox wrapper. I used this for forming the Large De Winton boiler shell in 2006!
