OK.. here's a few pix.



There's some things cut on my CNC for folks. Difference being they are all arcade accurate from plans made by tearing down an original part to draw myself vs taking jakobud's plans. Jakobuds plans while similar are miles away from arcade accurate.
I usually base my costs on materials cost plus a per hour rate on the cnc. Cheap things like hardboard coast me about 14 bucks a sheet from my supplier and take less than 5 minutes on the CNC to rout a simple profile. So, at a typical 100.00 per hour rate for the CNC work that's 1.66 a minute of CNC cutting time so a silly little hardboard template is about 8.00 at my normal shop rate. So, I add on say 15 bucks to cover an hour of labor to operate it, maybe 10.00 profit and you arrive at a retail price around 50.00 done.
A fully assembled cabinet, typically 200-300 perhaps more depending on the material used to build it and the complexity of the parts. Mainly due to the labor needed to assemble.
Just food for thought I guess.. been doing this a long time now myself so it's experience talking. My advice to you is if you're going to sell cabinets meant to replace originals you have some work to do. Just taking jakobod's plans is not enough, they just arent' right unless you're selling mame cabs where similar but not accurate is ok.
