So I received my new tap a few days ago. Took it into work today to get started
I started drilling out the existing 510. I think I ended up using a 5/16" bit to finally pop it loose. Was just pressed in
And after debating on what size bit to actually use for the pre-tap hole, I settled on a 3/8 bit
Seeing as how i am tapping into aluminum with some very fine threads, by hand was the only way. Used plenty of cutting oil to make it go nice
I must say, after getting it in 1/4 of the way, I was a little worried. Aluminum is soft, and it felt like it was dropping after turning a few rotations. My fear was that after cutting a thread, it was somehow being cut away. I was going to wind up with nothing but a smooth hole.
But alas, it is completed. I kept with it, and went all the way through. Removed the tap from the handle and let it pass right through the hole
I had originally planned on using the 10mm 510, which is just a threaded shaft with no top plate. But after placing it inside, i decided it didnt look good. So I am going to end up using the 14mm
It also ends up shorter in the heatsink than the stock one did.
Everything is currently going through a few ultrasonic cycles to remove the oil.
Thats all for now. Work is going back onto overtime. So i may have to hold off until sunday at the earliest to assemble and test.
Trying to settle on how I want to keep it in there. Either conductive glue on the threads so I woudl never be able to remove it, or some conductive grease on threads and a dab of glue/loctite at the bottom. And some 1-1.5mm thick thermal pads for the board/heatsink connection.
I really wish I woudlve taken a resistance reading before I drilled the stock one out though. For comparisons sake and i believe the way its made is whats giving me that difference in resistance readings. But wanted to compare to the new one.
