OK, so another update. Here's what I've been doing...
DC Heater circuit:
So, I drilled out my chassis for a 250 Ohm, 4W pot and another little pre-made board. I'm using a .1 uF cap that my friend Olaf sent me that fits perfectly in this tight spot. Here;s a pic:
Will solder this up when I get some good bus wire for the heaters...
Relay power board construction:
I took some red swirl board material I ordered from Watts Tube Amps and measure what I needed. The boards I got were 2" wide and I needed 1 3/4", so I measured and then used a razor cutter to due the initial cut with a straight edge. I then used a really small mitre saw to cut the board. I then printed out a board template and taped it to my cut board. You can kinda see what I did here at the top right of the paper attached to the board. My flash took away most of the detail, but you can see a couple of screw and turret holes.:
I then used a center punch to carefully mark the hole spots on the template into the board and then drilled it out with my press. I then took some cool turrets that Olaf sent me (he sent me the correct bit as well) and hammered them in - believe me - they are not going anywhere. I then assembled the components and tested out the standoffs I'll be using. Here is what the relay power board looks like now:
I haven't soldered anything because first I ned to drill out my chassis for the board as well as the bridge rectifier and 7806 voltage rectifier that are part of the circuit. These will be screwed into the board and I just find it easier to get everything situated, all wires connected and then solder everything together. That'll be the next step...
