“Biggest vs largest vs greatest achievement”

This post, I wrote “biggest achievement”, then double-took myself and wondered whether it ought to be greatest, or largest. Answer, by popular opinion is…greatest achievement. Neither biggest nor largest even get a look in :

The Big Stack Overflow 1000

I hit 1000+ reputation on stack overflow. I feel this is quite an achievement, one of my biggest (or greatest, or largest? Not sure.). I didn’t celebrate, aside from a quiet fist pump.

Conductivity of HOT Bathroom Tiles

This entry is part 15 of 15 in the series Dog's Head

In “Casting Day Fuzzy Feeling” part 1 I found very hot bathroom tiles conduct electricity, so the ceramic shield that I built for my aluminium furnace was pretty much useless. It got me thinking “How useless”: Was the glowing hot porcelain conducting electricity going to kill me? I spent w-aaaaaaaaa-y too […]

Casting Day Fuzzy Feeling

This entry is part 14 of 15 in the series Dog's Head

So I posted about my ceramic shield. I thought this was a wonderful thing – addressing a flaw in other ‘amateur’. electric furnace designs. I may have even revelled in my brilliance in that post (I did refer, at one point, to a likeness with the heat shields on the Space […]

Casting Day Brown Gas

This entry is part 13 of 15 in the series Dog's Head

“What’s that pink gas”, my wife can be heard on video in my last post. I muttered something – to allay fears- but I did wonder. Firstly: Definitely not pink. Definitely brown. Proof that Zoe walks around with permanent rose-tinted glasses on. Secondly: It’s due to 800C chlorine eating my steel […]

Dog’s Head: Wax Cast. Take 2

This entry is part 10 of 15 in the series Dog's Head

So I am using the lost-wax casting to make my aluminium dog’s head. My first crack at making the wax cast was ‘okay’ but there were bubbles and a lopped off an ear tip. I have had another go. First time around I just used a big (paraffin) wax candle – […]

Aluminium Furnace: Some Pics

This entry is part 9 of 15 in the series Dog's Head

I have furnace up-and-running, well up-and-heating at least. I have taken it to 800C so far…aluminium melts at c650C. No problems (well one problem, see below, nearly none.)   The Earthing/ RCD Problem I ran the mains earth wire from the power lead to the metal enclosure. But when I […]
