5mm bigger than the rivit or bolt ur using, this helps lineing all the holes up

about half a mm biger than bolt or rivit in my view, gives a little clearence so you can line up and rivit or bolt a free fitting, but isnt like a stick in a bucket and the chequer could if bolts or rivits rattle loose slide all over the place

Its hardly rocket science, use the correct size drill for the fixings you are using, so if its an M5 bolt use a 5mm drill (or 6 tops) but dont oversize them by loads as itll be sloppy.

Simply place in position, mark one hole, drill and bolt this then proceed to drill and bolt the others in turn, no messing about and no chance of it not fitting!

Close but no cigar.


In the example of M5, the 5 refers to the nominal diameter of the bolt, the correct size drill varies, but for a close clearence fit then the desired size is 5.3mm, but as most drill bit sets only do half sizes then 5.5mm will do.

You can use a 5mm drill, but the tolerances will be on the limit, which can result in the operator "wriggling" the drill to make the hole slightly bigger so that the rivit or bolt fits.

I'll take the cigar thanks - due to the wings/body being ali by the time you have used an M5 drillbit itll be exactly the right size - guarenteed without wiggling!!

Also when bolting it in because its threaded and again in ali you can bolt it through a hole which is slightly smaller without any ill consiquences at all. Interferance fit is fine for this kind of thing, it doesnt need to be a clearance hole and certainly not several mm larger like some suggested!
