Not really sure where to put this, so I'll put it here and link it up...
Housing is 500mm x 190mm x 38mm front height (lower if you take in the knurl) and 50mm at the back, or in other words as slim as I could make it and still fit everything in. Side walls are doubled 16mm polished MDF with internal reinforcing as shown. Face is 3mm galvanised steel plate powdercoated for durability. It's strong enough that I could stand on it. Total weight is 3.5Kg, which is apparently quite light. Most sticks you buy, like the Qanba Q4 for example, weigh about 5.5Kg. Believe me it's heavy enough.
Sanwa OBSF buttons, Sanwa JLF stick tuned with a 1.5lb spring (+50%) and a +0.5mm actuator customised further with electrical tape. The stick now has a fast engage (reduced deadzone) and a small throw past the engage in each direction thanks to the electrical tape.
The stick itself is so damn precise it's unbelievable. I was worried about having to start from scratch skills-wise at first, but in PSP Tekken 6 managed to chain Armour King's Dark Upper (f,n,d,df+2) to get the second as a juggle, so i'm right on track. Will be wavedashing for fun in no time
