Nice job there, Iain.  Looking forward to seeing it fired up  :D

Charlotte's right about how many drill bits you get through

You may be using too high a speed.

You want medium/slow speed on the drill, and plenty of pressure. Cutting oil will help too.

If you attack stainless with a high speed, the drill bit will quuickly overheat and the cutting edge will be destroyed instantly. You're then basically left drilling holes with a nail.

You should always see a nice neat little curl of swarf rising out of the hole when drilling stainless, that shows you are cutting metal. No swarf exiting can mean your drill bit is just spinning instead of biting, which will build heat and bugger the bit.

The stove looks great, nice work!

We ought to have a cook-off at Dunwich.

Chalotte's Cool Camp-stove Cook-off, featuring Wobble's, Wascally Weasel's & Wowbagger's Wonderful Wilkinsons Woodburners.  ;D

Sadly, I can claim no credit for the construction of mine: as my previous post was meant to indicate, it's a Bush Buddy.
Bach without a doubt.

Yeah, it's a bugger of a job alright.  I've worked with stainless on lathes and milling machines and it's easier to run slowly on them (as well as to set up a recycled stream of coolant/lubricant).  My little drill press is somewhat less refined.  Although it's still possible, I'll grant you.

Also, I suspect that the grade of stainless used by whoever makes these things for Wilcos doesn't help.

Yes, it looks most impressive. I'd love to have a go at one but I don't think I'd have much chance with a hand held Black & Decker and a selection of already totally knackered drill bits.

I didn't break or blunt any drill bits in making mine.  ???

Apart from when I tried using a tank cutter to do the lid.  :facepalm:

I think we must be running the drill presses slower than Charlotte.
If it ain't broke, fix it 'til it is...

I've found a rather handy accessory that will make you the envy of any campsite.

I love Stirling engines.  Ever since I saw Adam Hart-Davis playing with one.  But surely <a href="http://www.youtube.com/v/cqmeYc8GWmA&rel=1" target="_blank">http://www.youtube.com/v/cqmeYc8GWmA&rel=1</a> ;)

Now this is rocket science, Stirling engines are being considered to be used on some space missions to replace RTGs (Radio-isotopic Thermoelectric Generators).

They're more efficient than thermocouples at generating electricity, but produce a lot more vibration, which means that they aren't a good idea on something like an orbiting observatory, but are useful on manned spacecraft which already have a lot of vibration (from people!)

One place where NASA was considering using them was on a next generation version of the Lunar Rover, which would have had 6 wheels instead of 4, and could be driven remotely from Earth as a teleoperated device when not being driven around by an astronaut.

So, they would be a sensible choice for a camp fire powered generator, could one be built small and lightweight enough.

OT ramble:  The original Lunar Rovers cost $38 million dollars to develop, and travelled just over 56 miles in total, so that works out at around $677000 per mile, which makes the running costs of my Corsa seem quite reasonable. ;D
Actually, it is rocket science.

Update - the stove really does gassify rather than burn.  Here's what I emptied out of it at Dunwich after I'd cooked my dinner:

Now that you're officially a charcoal burner, you need an adder! (as in Swallows and Amazons).

The key question is will Charlotte be Susan or Titty?


(Mind you I've always seen her more in the Nancy role)


And in other news: Went to Wilko's today. A transaction was carried out. Let the drilling begin.

Turns out Nancy is the only one to have her own Wikipedia page. http://en.wikipedia.org/wiki/Nancy_Blackett_%28character%29

Nancy is sometimes critically viewed as a subversive character for girl readers, suggesting an alternative choice to feminine domesticity, and one commentator obliquely hinted Nancy would have fulfilled a lesbian destiny.
Hmm

Nancy Blackett is one of the coolest female child/teenage characters in fiction.  When I don't grow up I want to be just like her.

This bit from the end of the wiki article says it all for me:

"Today, Nancy is viewed as a subversive figure who, in the context of interwar Britain, offered young girls the possibility of an alternative route to adulthood. The character has been cited by feminist author and academic Sara Maitland  as a childhood role model "who transcended the restriction of femininity without succumbing to the lure of male-identification" and a "hero who had all the characteristics necessary for the job; who lived between the countries of the material and the imaginary".

There are some odd bits here and there in the Ransome books but the invention of Nancy Blackett forgives all faults IMHO.

On balance I think the portable campfireness is the major plus for me (against the slower than gas or meths cook time).  It would feel wrong to go home from a camp without that smell.  Smells like victory the outdoors should.

On balance I'm inclined to agree.  Not all that good for my Stupid Lungs thobut, so perhaps not entirely sensible for cycle touring when the wind can't be relied on to blow in a consistent direction.

With this is mind, do you see the phrase "Prize galoot" replacing "donkey felching cock womble" in the lexicon of the cyclist-about-town?

Ransome was a red under the bed.  He incorporated his vision of socialist fulfilment into the freedom of discovery exercised by the children, and his belief in gender equality very strikingly in Nancy Blackett.

Whilst on holiday in the Lakes earlier this year we took a boat trip on Coniston.  We sailed past the end of the field which was supposed to be the setting for the scene at the beginning of Swallows and Amazons where the children run "tacking" down the field towards the lake.

I just thought I would throw that in. As you were  :-*

Question: Since Charlotte's stove was gasifying and Weasel's one was behaving a tad more like a fire bucket, was there a noticeable difference in cooking power?
