How do you drill holes for Kadee Nut-Bolt-Washer?

[electrolove]

I wonder what tool I should use to drill holes for Kadee Nut-Bolt-Washer? I can read the following on Kadee's webpage.

Die-cast metal Nut-Bolt-Washer Shank press fits 1/32" hole.

Where do I get the drills in that size?

Your LHS should have what you'll need,offhand I'de say it's about a #70-75 bit, but it maybe smaller, you'll also need a pin vise to drill it.

electrolove? Can I make a suggestion? I know you live in Europe and you really don't have a Local Hobby Shop. Why don't you go into your profile and put your location or country in so it shows up under your name? This way people won't assume that it's as easy as a short car ride to get what you need.

You can order what you need from www.micromark.com they have plenty of small drill bits and drill bit holders so you can finish lots of modeling projects. Just go to "hand tools".

A very good suggestion. It's done.

I will look at micromark and see what I can find, thanks.

A 1/32" drill bit is equivalent to .0313 inch, .7950mm, or a Number 67 Drill Bit.

Thanks, this is exactly the info I need. Inch to a Swede is very strange. I know that 1 inch = 2,54 cm but when you guys are talking about 1/32" and things like that, I'm totally lost [:D]

Just because I'm very curious. Do you use mm, cm and meter at all in the US?

BTW: Number 67 drill, what system is that?

Electro,
A pin vise and a tap set are essential tools in my opinion. I will usually
buy bits as I need them, but I have a hobby shop within five minutes of
my house. You might think about getting some of the basic sizes of bits if
you don't have quick access to them. Good luck, Dave

electrolove,

With practically every hobby item made in China today, metric tools are becoming a necessity. I spent 26 years in the U.S. Army and our topographic maps have always been in metric measurements.

Machinists' drill bits are graded according to a "wire size" standard that is based, loosely but not precisely, on thousands of an inch. I have a set of 20 wire size bits purchased from Micro-Mark, which someone else suggested to you, that are numbered from size #60 to #41, with #60 being the smallest. Wire size bits are equivalent to the following:

Wire size / inch / Metric (mm)

I hope this doesn't just make things more confusing for you.

I had students (back in the day when I was a professor) who swore that there was no need for them to learn metric, that they could do their physics labs and homework just as effectively in English units as metric.

Talk about your provincial thinking! [:p]

I would sometimes put a question on first homework assignment (which would generally be about units algebra) in which they had to convert 'c' (the speed of light, 2.998x10^8 m/s) to furlongs/fortnight (perfectly valid English-system units). [}:)] While it didn't make them happer, it typically shut them up....

[edkowal]

Wow... furlongs per fortnight !!! I remember that unit from my own college days many moons ago.

It was part of one of the standard wisecracks from the engineering students when some situation struck them as particularly ridiculous: "Could you give that to me in furlongs per fortnight, please?"

Thanks for the reminder.

edkowal and bpickering:

Furlongs per fortnight, I have never heard of that, and I do not think I'm missing it either. [xx(] Thanks for the great answers. I have said it before and I say it again, I love this forum. [:D]

cacole:

Confusing, hehe, YES! But with a table like that it's pretty easy. Thanks.
