Casting Day Fuzzy Feeling

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

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

Casting Day Brown Gas

This entry is part 13 of 14 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 14 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 14 in the series Dog's Head

Making the plaster cast of the to-be lost wax copy of the head. This whole process is a bit tedious to be honest, and mucky. I have taken the lost-wax path, but am starting to wonder if there isn’t some easier way, using the 3d print as the “lost-wax”. and avoiding making […]

Dog’s Head: Wax Cast. Take 2

This entry is part 10 of 14 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 14 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 think I alluded to it in furnace post on electronics? An issue I had with earthing. […]

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 […]

Dog’s Head: Furnace Ceramic Sheild

This entry is part 8 of 14 in the series Dog's Head

To reduce the risk of electrocuting myself, I made a ceramic box to separate the bare-metal and electrically-live heating coil from the inside of my furnace. Seemed a good idea. ALERT & UPDATE: A bit of an ‘issue’ with this whole idea. Bathroom tiles *might* (pretty sure they do) conduct […]

Dog’s Head: Aluminium Furnace Electronics

This entry is part 6 of 14 in the series Dog's Head

Quick one – the electronics for my aluminium foundry. AliExpress shopping list was in my last post. A Couple of Progress Photos I got all the electronics wired up and tested it by sticking the thermocouple in the oven while I was cooking a frozen chicken kiev for dinner – I […]
