Time for a quick update... Lots going on behind the scenes getting the machine to a point where I can power up. I've been working on little bits and pieces almost non-stop after work. Wed and Thursday night last week; I began assembling the new Lamp Matrix board. It's about 1/3rd the size of the original and uses MOSFETs instead of SCRs. Here's the board getting "skillet reflowed" with all the SMT parts.


While assembling the head; I noticed that all the display brackets were rusted pretty good. So I needed to take them to techshop and sandblast the rust off. I figured it was time to make a day of it at techshop on Sunday... so I queued up a bunch of work.

I attempted to mount the 48V transformer for the solenoids but quickly realized I didn't have the right hardware. I didn't want it mounted in the Backbox; instead I opted to mount it on the wood rail on the bottom of the cabinet. It was time to create a bracket for the transformer; so I decided to use the stainless steel leftovers I used for the inlane mechanism. Some CAD work Saturday night yielded the following watercut bracket:


Put it in the Techshop break and:


A M8x1.25 tap for the center hole and some wood screws; and we have the bracket installed ready for use:


Here's a test fit of the transformer:

:thumbs up:

I decided I was going to powdercoat the parts with a Nickel color since I had a bunch of it in the garage. I took a whole bunch of parts to get sandblasted. Coindoor parts & hinges, and the bottom metal sheet metal on the underside of the cabinet.

Bottom Metal sheet before:


After Sandblasting and powdercoat:


Also did the display trays; but no pictures yet. Will post them later when I have them installed.

That's about it for tonights update.
It's suppose to be very cold here in Austin tomorrow... so unsure how much time I'm going to spend it the garage. If I feel up-to-it; I'm going to try and wire the transformer to the PSU board. Maybe do some work on the topside of the PF.

I hope to power up the machine sometime this week. :Fingers crossed:
