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 […]


Website of the Week: &what;

&what;   Or amp-what.com in your browser, if you ever need a character that isn’t on your keyboard. Three things I like about it: No ads, real simple It has a search box. So if you want a triangle, you search for NCR-code Δ  Just kidding, you just search for ‘triangle’. Here is one▲from a […]


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: Casting Day

This entry is part 12 of 15 in the series Dog's Head

The time has come – Casting Day. My last post took me to step (9) of the Wikipedia page process for lost-wax casting. Now its ‘No 10’: Pouring. Big Day! Loading up the Crucible I loaded up my steel crucible with: Aluminium (!) A bit of chlorine tablet Some charcoal Aluminium […]


Dog’s Head: Plaster Mould

This entry is part 11 of 15 in the series Dog's Head

Making the plaster cast of the to-be-lost wax copy of the dog’s head: This whole process is a bit tedious, to be honest. I am starting to wonder if there isn’t some easier way, using the 3d print as the “lost-wax-copy” and skipping all these stages. Anyway. Process Steps 6-9 on Wikipedia […]


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 […]


Graveyard Spiral REDUX

This entry is part 5 of 5 in the series Quadcopter

I have access to Adobe Premiere Pro and have always felt a little overwhelmed by it (the software) and, creative-wise, the additional dimensions of time and sound. Compared to playing with a single image in Photoshop, getting anything good going with Premiere has seemed to take an immense amount of time and […]


Quadcopter Crash Landing

This entry is part 4 of 5 in the series Quadcopter

For a while, I’ve had my quadcopter up-and-running. I am not the best pilot in the world, but getting better. We are staying at a place where people are sparse (I think people feel a little uncomfortable about drones) so I decided to duct tape my GoPro Hero 5 Black on the […]
