PTS2 and Fatman and heat sinking?

I am in the process of building my first Mag to LED conversion using the PTS2 and a Fatman driver.

My question is what is the best way to make sure the Fatman is heat-sinked to something? Since the hole in the middle of the underside of the PTS is where the wires come through this won't allow the Fatman to be sinked there, or will it? If it is then would it be necessary to use a copious amount of thermal epoxy to get it to stick over the wires?

Or would it be better to dremel out a channel that the wires can rest in that will keep them from touching the Fatman when epoxied to the PTS?

Does anyone have any pictures of how they did theirs??

Thanks!

I can't really tell how you mounted the Fatman though. Would you mind elaborating a little? How would I do this with a PTS2?

Thanks!

Sorry, I'm not a specialist.

I have only seen the picture. The hole in the heatsink is perhaps for a screw?

best regards

mostly matters how much current you will be running through it.. i've never had to heat sink any more than just having the board itself stuck into a hole.. and i run really close to 2A through it... (input).. my suggestion to be overly cautious.. heat-paste the top of the inductor (what gets the hottest) and use some foam to push it into the side of the light between the PR base and the light (get creative if you already cut off the PR post). if you want to be really over-cautious.. use a tiny aluminum standoff to heatsink the switcher chip itself in a similar manner.
