Slider skirt rivets

[Coling955]

A really easy one. I've used the same MK319-BS rivets that are used on the slider canopy skirts somewhere else on the aeroplance but I can't remember where.
What I also can't remember is which drill size i used and which countersink. If anyone can advise I'd be most grateful.

Hi ?

See this spec sheet for MK319BS. I found that if you plan to use one from the outset drill 7/64" and use 3/32" dimple (preferably 120 degree) as this enlarges the hole slightly but if you have already drilled/dimpled #40, or intend to machine countersink, I found I had to go to #33 - I did do some test pieces with #30 and it appeared fine, especially if you don't have a #33 drill bit.

Hope this helps?
