Peter Daniel What type of fasteners are those?

[PHilgeman]

That you use on all of your chassis. It looks like a countersunk washer that you can use in order to get some flexibility by drilling your holes a bit larger. Into the countersunk washer fits you cool screw.

Where do you get those? I would be very interested in buying the washers alone for some size 8 counter-sunk screws.

Thank you,

It is a high tolerance brass bushing with 0.25 inside hole and 0.50 mounting hole. It accepts shallow counersink screws.

I don't use them much, mostly in the preamp, but I'm running out of them quickly. They come form aircraft industry and I would be interested myself, where to source more of those.

I can supply you some Hi-Lite 5/32 and 3/16 if you have a impact gun =)

[Peter Daniel]

Of course, I have impact guns. I even have an offset collar installation tool (by Atlas)

And I have some local friends who currently work in the industry, but I'm always on a lookout for nice fasteners.

I somehow never thought about using Hi-Lites in chassis building, but maybe it's something to think about. I used rivets recently, and I'm very satisfied with results.

They are not sqeezed too tight, I made counersink for lower manufactured head size

Let me know if you want some, I will make you a good price but without any tracability (That the reason I'm able to sell it =)).
I will check the quantity I have in stock.

Here's the other side. It will be sanded. so the rivets would be barely visible.

Why don't you just shave it? will give a even better finish no? That what we do here on Bombardier wing plank when we install interference fit freeze bushing to repair some damaged holes.

If you use a Dewalt Pilot drill after you drill with a standard drill for the rivet hole, you will get a nice little ledge to catch the Rivet head and have it flush to the material surface.

Micro shaver is about the only tool I don't have, but the aluminum parts have to be brushed and sanded anyway (for better appearance).
