I want to fit a Red Dot Finder to my scope and also have the 9 x 50 finder.

I therefore need to fit the Red Dot 'shoe' to the scope.

I havethe show but want to know what the best way to drill the OTA is. Also what do I do about not getting the bits/'dust' on the mirrors (both primary and secondary).

Do I need to use a powerdrill or will just screwing the screw with a screw driver work, are OTA skins very thick.

Probably a stupid question.

Hi beamer, If you are fitting the red dot shoe with micro bolts and nuts,

(3-4mm), then you would need a decent cordless drill-driver, and a NEW drill bit.

Invert the OTA so that the aperture is pointing to the floor, so that the swarf(?)

can drop to the ground, and not you-know-where!

as for self-tappers, you may have to exert quite a bit of pressure to get even the sharpest of screws to bite, and then you risk imploding the side of the tube,

or putting a slight indentation in it.

IMHO, I would opt for the Micro bolt and nut method, which can be found in any

modelling shop, or source 1 or 2 from an unused kiddies toy!, have found several nuts and bolts small enough for loads of finicky jobs like that!

Secondly, remember the golden rule, "Measure twice, Drill once!"

HTH.......

Thanks Aries.

I have the shoe and the nuts as/bolts as I am planning on removing the finder from my 130PM and transfering it to my Explorer 200.

I will defo go the drill route and will defo take care.

Good idea to turn the OTA upside down, I always worry the mirror will fall out.
