Chopped the marble hearth and back into useable pieces.
Collected a tumbledryer donor for heat shields. That's tomorrow's job though! ;) Committed now! :D

Used high temperature (450 C) enamel paint after rubbing down the stove pipe hole. A inexpensive way to control any errant wood fibres post cut.

Air gapped 1.2mm heatshield fitting ongoing. Steel came from a Burley WS air intake unit which I did not use.

I had forgotten how it is working with steel, bloody hard going!

That's the first metal shield in place. Air gapped to 15mm behind the shield with three 10mm vent holes at 12 o'clock on the outside. Once I fibreglass wrap the main pipe and then overwrap with titanium exhaust pipe we should be good. I've left 8mm surface space on the pipe so will manage a good thick isolating wrap.

The donor Burley air box has shrunk considerably. :)

That's the heatshield finished on the outside bar an edge seal and final paint. All segment gaps in heatshield fire cemented and cured with a map gas gun.

Will start chopping up the tumble dryer tomorrow to complete inside main shield.

Heatshield work complete. The broken tumbledryer was an excellent donor as was the baking tray of spare. :D

A good airgap left at bottom of heatshield for air movement.

Looking very good JB, nice and neat, the way this summer is stacking up you will be needing the WBS on soon!

We had two weeks of sun when on holiday in St Ives but since we got back its been more like early spring than summer.

Cheers Moxi, glad u got the weather on holiday. On/off up here, sunny at the moment.

WBS2 is on its first burn in its second life. Temps are looking good, no anomalies. Getting up to temp and burning off years of internal whatever. French scalloped brocante kettle is on its test too! :D

Feels great to have achieved this for under £150.

Way to go Joe - good job, recycling and repurposing. Ideal.

I’d imagine the cabin would be quite cosy in the winter - you could always get the kettle going full chat and use it as a sauna :shock:

Flue exit point a couple of inches from cabin wall 195 degs. Highest temp seen on any of the flue heatsheild build 90 deg. :D

Burnt most of the crap off now. Last fella must have burning coal and cresoted pallets back in the day! :x

This has been an epic little project and in the back of my mind for yonks. Manipulates my engineers, gypsy scrap man and also caveman sides.

If the grid falls over (when), we will have an insulated easily heated space to operate from. Hot water, cooking and a campbed. Sorted, literally sorted.

Going to ramp it up now to burn any last crap off. :)
