I went to my local DIY store (Homebase in Ireland) but all the drill bits are in millimetres.

Fine you say. How many mm in an inch...28mm

But all the bits thay had were in standard sizes 22mm, 25mm and 32mm. None in 28mm !

So, am I wrong about the 1 1/8th inch ? Do I need another size ?
OR...
Does this store just not have a very good selection ?

Help much appreciated :)

Also, whats the best way to tighten/loosen the nut on a pushbutton ?

Cheers.

I managed to find a 28mm bit at my local Homebase but it was a while ago. Try a specialist DIY or Hardware shop as they tend to carry a larger range of theses types of items.

Actually I got both a 28mm and a 30mm spade bit. The 28mm was a tad too narrow and the 30mm too wide. The 28mm worked best after some extra enlarging of the holes, but it wasn't easy nor pretty. The investment in a proper 1 1/8" forstner bit might be overspending, but it sure makes things a lot easier.

yes  :P

Course not. Its just a handy store for me  ;)

Anyway, the 28mm I picked up worked perfectly. The buttons couldn't fit any better. I've modified my new SlikStik with two more buttons which makes it now even better.

Thanks for all the help.

I know this is an old thread, but I just wanted to share the bit that I'm using for cutting the button and joystick holes.  I'm not sure the name of it, but it's adjustable and works well with laminate.  The trick if you have laminate already applied, to cut the top part until the laminate comes off in the size of the hole, then do the rest of the cutting from the underside.

Also, in one of the drill accessories kits I bought, it came with a 1 1/8 (probably a standard size) round sanding bit.  Works very nicely for cleaning up the hole after drilling!

The pic is attached.  The very top left is a sample hole I cut, then the second hole is one that is in progress.  The drill has the sanding bit attached, and the other cross shaped piece is the adjustable hole bit.

If anyone wants one of these adjustable bits, I may be able get them for about $12 shipped!  The bit is adjustable from 1 1/16" to about 4".  There is also another bit that attaches on the end for cutting holes in really thin material (like just laminate or something).
