I have some heaters Robotech sent me and I plan on using one of them for the simulator. Each one is capable of 150watts so one "should" be enough being I only want to use maybe 70watts.

What I plan to do is very similar to RoboTech's design in the picture below except I will have a heater in place of the thermoprobe in the middle and I will only be using one heater. I had planned on using all Copper on mine mainly because I have enough of it. I was thining about making it all one peice as opposed to Robo's design. I think the thermal transfer would be better but i would also have to make a new part in the event of future core revisions. Which is no big deal.

So my real question is where to stick the probe? Should I cross drill into the milled out die and epoxy it in? It seems the only logical thing to do?

Next is insulation. I thought about making a silicone sealant square around it but then started digging into silicons thermal properties and it looks like it is not going to cut it. Would the styrofoam style insulation work alright? The stuff they use on houses now days instead of the fluffy pink/yellow stuff.

I was thining about blocking it in with that and then making a plexi glass shell around it to hold it all in and tight.

Next is the power supply. Anyone know a decent place to pick up a adjustable DC power supply. I need at least 70watts and preferable 100watts, just to have some extra adjustment, of power.

I was going to use a computer supply but have failed to figure out how to make it adjustable.
