p60 thermal potting

Does anyone have a good source for some “pure” copper rounds?

I want to thermal pot the driver side of the p60 pill with some copper/solder to add more thermal mass. There is usually a bunch of space in there anyways.

Also, I can’t find the thread but how is the 16mm sinkpad GB coming along?

I suggest some copper wire. Very cheap and its also copper.

You may wish to check Etsy.com for copper rounds.

As NightCrawl suggested, thick copper wire can also be cut down for this use.

Good idea, I may just go with the copper wire since it is so simple. I’ll take a look at that site too as I wanted rounds to make a “cleaner” build.
