Build II - Paradox MJ5 - New design!

Thanks!

I looked up those ribbed ones, same as StewMac has. Those are 3/8" in diameter (~ 9.5 mm). They will fit in 10 mm holes, although you should use a 3/8" bit.

The ones I have are 10.5 mm and do not fit in 10 mm holes. I tested it to be sure, but the outcome wasn't a surprise.

As brad point drill bits, as well as forstner bits go per mm, you don't have 10.5 mm bits. There are 11 mm bits, but not as a brad point (less precise ones are available, those single blades, don't know how you call them). I want a snug fit, so maybe I need some kind of imperial size.

I will visit the hobby store to look for a solution.
 
Fractional inch sizes would not be your best bet. In inch system drills, a machinist's letter drill is much closer.

13/32" = .4063" = 10.32 mm
Z = .4130" = 10.49 mm
10.5 mm = .4134"
27/64" = .4219" = 10.72 mm

I don't know whether they ship to Europe, but McMaster-Carr has half a dozen versions of both the Z drill and the true 10.5 mm bit.

Thanks Pete! I just visited the hobby store and found a good quality 11 mm brad point bit. I'm going to test the fit with that (maybe the finish will fill in the gap). They also had a 10.5 mm metal drill bit, but I prefer a wood bit and it was in a set of about 20 bits that I do not need, costing 35 euros in total. If I'm not satisfied with the 11 mm brad point wood bit, I am going to visit a specialized tool store in the next week.
 
My feelings exactly. :)

After checking everything again I prepared for drilling one of the scariest mounting holes of the bass:

And ready. Drilled exactly on the marked spots. So far, so good:

Now, there's no way back:

String through holes are yet to be made. I tried fitting it in a 11 mm hole and it's a bit loose, but with only one to two layers of masking tape it's a snug fit. With the finish incorporated, 11 mm is probably going to do the trick. Now I need to find a way to make the five holes align perfectly.

Only 49 holes left. And the neck profile.
