I tested my new electric furnace today to see if it will melt aluminum fast enough, it was even faster than my oil burned furnace so I am very satisfied. As soon as the newly developed Moldlay wax filament arrives in the mail I will try to print wax models in the 3D printer, if it works I can cast them in plaster and do lost wax castings all day long! Just thinking about the possibilities makes my ball sack tingle. Cheers! /Anders

I´ve started the tedious job of restoring the pics in the beginning of the build thread that disappeared when I changed web server, boring job but it makes reading the posts a bit more interesting.

Hi Anders,
Thanks for the pictures! It was already very interesting before, now it's even better with all the pictures!
That's a very nice furnace! I think melting aluminium with this is very clean, I'm surprised that electricity is powerful enough. Can I ask you how much power it uses, and how the heating works? Is it just a coiled wire put into the slot?
Cheers, Alain

You are welcome, I started a while ago with the pics in the first post but must have forgotten to fix the rest. It was a nostalgy trip to see the progress over the years. The furnace has a single phase heater running on 16A, I think it was in the region of 1500W or so. I was actually a bit sceptical about it since I cannot find many DIY:ers on youtube who use electric furnaces but it turned out that it heated up fairly quick and once the crucible was glowing and the aluminum pieces dropped in they melted in half an hour or so. The best thing about it is the ability to control the heat, with a diesel burner it is difficult to measure the temps with the open flames heating the thermocouple. My plan is to preheat/dry out the plaster molds in it up to 700C or so, then move them to a kitchen oven to keep them at 250C while I melt the aluminum. If the plaster molds are allowed to cool below 220C or so they are prone to cracking so they need to be kept hot until the metal is poured. Cheers! /Anders

Thanks John! I just have to figure out how to get the bike out of the workshop without damaging the tyres, the needle sharp spikes won´t like being rolled over the concrete floor.

I ran the bike a couple of hours ago, everything went fine except that the relocated oil filter touched the fuel pump body and effectively grounding it causing the PWM controller to run the pump at full speed... Other than that it behaved as expected, the thread paste smoked a lot like it use to do before it has cured (burned away...) and the temps were a bit high as usually when the freepower is locked up. Cheers! /Anders

Hi Anders, Nice test run...very large scary flames though.
Can you please share the link to the oil supply and suction pump you are using with your engine.i need the exact part.
Cheers, Patty

Hi Anders
LOL ...............are you practising to be a top fuel dragster with that Vee of flames ;-)
Bike is looking in great condition for the show .
Did the engine handle the bit of extra fuel without complaint ??
Cheers John
