Raceco chassis screw holes

[badhoopty]

Heres a pic of a raceco chassis i picked up from shodog awhile back. all the areas where a countersink would be are flat and i assume its up to the builder to countersink the holes.

do i just use a countersink on what i assume are plastic sleeves molded into the foam composite?

i would hate to try that and screw it up...

[badhoopty]

nobody?

what are ya, chicken?

Do you have access to a dremel or similar drillpress?? One which has ability to clamp work down would be a bonus. Than matchup the bevel on your flathead with the counersink you will be using.
I'D use medium to slow drill speed and slow feed imput, don't force the counter sink, GOOD LUCK LMK RESULTS, GRIZZLY

Those holes look like fiberglass grommets. The key is to use a real countersink cage with the right degree of angle and use a pilot shaft. at the bare minimum use a counter sink bit with a drill press. don't try to do it with a drill bit as it is the wrong angle.

I wouldn't think of doing it with a drill bit.

I have the right countersink, but just a hand drill, no press.

With a drill press you can set the depth you need and all the holes would be consistant. you can do it by hand, but it will take alot longer, and Ide do a little at a time and try the screw till it sits flush. As long as you go slow and stay perpendicular you would be fine. Best to do with a press though.

i guess i'll just not put that one together for awhile.

i really need to buy a house so i can buy some serious garage hardware.

I just tried that, and I got the house, but the garage hardware still isnt there. the big ass tool box I wanted, still not here. A stand up drill press, nowhere to be found. A nice Mill and lathe, isnt even a thought at this point.

Damn house isnt cheap. Buy the toys before you get a house!

I could always fix you up with a hobbydrill press that you mount your drill in, install your countersink. IT HAS A SMALLwork plaatform that adjust to height, angle. It'a what i used before I grabbed the dremel set. LMK IF IT'S OF ANY USE TO YOU. I'M sure a deal could be struck, GRIZZLY

I countersank my CF chassis using #8 drill bit. Using bare hand with a slight pressure. Do it slowly so you have a nice cut and can measure if its sunk enough. You can try #10 drill bit for the typical rc10 counter sunk screws (those big ones). Before doing, you can compare the degree of between the screws and drill bit.

I might have you beat. I will sometimes be searching eBay and stop on an interesting item just to find out it's one of my listings
