Spray painting and the big slappy mod
2nd update of the day:-
So I played around with my own version of the big slappy mod for the Iwaki - the idea is you tap the cylinder res for a much larger feed for the pump. The pump can't be on it's back so you need a nice slow 90 degree bend. The tough part is then getting down to the 5/8 OD pipe that is the inlet to the Iwaki. Here I used 1" pipe going to a 1/2" female converter fitted with a 5/8" brass barb. I butted the barb up right against the inlet and stretched some 0.5" tube over it:
The feed may not be quite as good as the original big slappy as that only had a bout 3/4" of 5/8 inlet tube, vs this 2.5" on this version. However the downpipe is 1" instead of the 3/4" that was used. So hopefully the extra width balances it out a bit. Here's a photo of the original big slappy:
and amuseme's version:
We'll see I might change to what they did, I feel like it might have better performance.
Also started spray painting test colors on a dead GT. I made a quick spray booth:
Done - there's some metallic flake in the paint, the color isn't quite as orange as the tube though:
Then a final comparison with it mounted on the 120 rad (this rad is just for the motherboard block loop). The rad will be painted silver to match:
So what do you think? Are the colors close enough? Both are slightly off. I wonder if I can get a color match from the powder coat supplier. I think I'll look for a different red at the least tomorrow. The match does depend on the lighting though.
