One of my old penny arcade machines was missing the entire coin mechanism so I built my own internal mech but then I was left with a gaping big hole in the front of the machine.
Most of the time these are just a plain piece of steel with a slot cut in it to suit our coins but I’d seen online a coin entrance that actually had 1d (1 penny) cast into the entrance so I started researching.
Following lots of you tube videos I went about building my own furnace.
After I was happy I could melt the Aluminium cans down I started working on the pattern.
Started with a piece of clear Perspex which I cut to size and marked out the holes etc.
Scribbled our the rough shape of the 1d and set about carving it out of the perspex as usual I forgot to take photos along the way but here it is very roughly
After more sanding and some paint do you could actually see what was going on it started looking like what I was after
Before I went throwing any more money at this thing I decided to attempt one out regular playground sand which gave me the “ yep this might actually be do able
Don’t laugh to hard
Ordered some green casting sand and had a go at the real deal wasn’t sure what was going to happen being so thin but what the hell let’s have a crack
Sadly no photos of the mould apart was to excited to get making
Well here goes nothing
Straight out of the mould
Cut off the unwanted vents and stuff file and sand the raised 1d them polish the whole thing and there I have a new coin entry for my old penny arcade machine using old beer cans
Pretty happy with the first attempt next time I’ll make it a little thicker to give me more meat to work with for the finished product but it serves its purpose.
Now what to make next
