Why are there no holes in the heatsink to mount the current limit resistors (R37 & R38) The assembly instructions say you can use thermal tape, but why not just drill the hole in the heat sink and mount them like the rest of the similar compontnents? I don't want them vibrating around and if the board is shorted I want the resistors to have all the heat dissapation they can get.
The Ohmite datasheet says

 

did you already buy your kit? All of the kits I have DO have holes in both the resistors and the heat sink. See the pic in the FAQ.

 

Yeah I did see that in the faq. I got my kit from DIY autotune. I was just curious. The MS site is very ambiguous.

thats 8 holes for 10 parts?

This is what really got me scratching my head. It gives the same instructions for R38.

 

I'll have to talk to JErry over at diyautotune, and ask him what's up with the current-limit resistors... I've gotten all my kits from glensgarage so far, and his have holes in them which go through the heatsink and board.

 

The initial scheme was the thermal tape and no holes; Glen was able to source these resistors in a real TO220 package w/ hole. They are apparently hard to get with hole.... I have purposely ran the resistors into limit mode for several minutes without contact with a heat sink and they only got mildly warm, maybe I'll do that again and see what the IR gun says my perception of mildly warm is.

-Mike, who does like the cleaner look of the "holed" resistors and potential peace of mind as well....

 

Thanks for all the info and piece of mind guys. I did find two small pieces of the thermal double sided tape that is described in the MS build instructions. It is good to know that it isn't really much of a concearn anyway (pmrobert).
