Do you really need a press fit to hold the pins in place? Unless the application is mobile, the weight of the shelves will hold the pins in place. Worst case, use 3/16 (.1875 inch) steel dowel pins if metric is too confusing.

25.4 mm = 1 inch.

divide 5 mm by 25.4 and answer will be in inches.

Then you will have to convert decimal to fractions.

If you can't wrap your head around metric, measure the pin in inches.

Here's my very low-tech method. Drill several holes in a piece of scrap wood with bits that look about the right size. Try the pin in the holes & pick the size you like. No thinking needed!

1mm is .0394. 5mm is between 3/16 and 13/64.

My low tech braille method would be bring the pin to the drill index box and stick in whatever hole looks close then keep trying smaller and smaller holes until I reach the first hole it does not fit.

All done, snug fit and I did not even have to waste time trying to find my glasses.

I agree with determined, try the pin in the index hole until it won't fit. Close enough and no mental mathematics error. I like to invoke the KISS principle, keep it simple stupid . that's me being the stupid one. gobble

BUT, one thing nobody has mentioned is that drill bits in wood drill slightly oversize. If you want the dowel pin snug you may need to use a bit smaller than the pins.

Grab several bits, drill a hole or two with each bit and test with a couple dowel pins, the pins can vary in size too.

I was trying the index hole and would find one that the pin fit correctlt, then would take the bit from that hole and just feeling it could tell it was smaller than the pin, same way for the next bit.

When the pins are loose in the hole they want to keep falling out before you can lay a shelf on them. 3 pins for shelf fit good, forth somebody before I got the cabinets some how screwed up the forth hole that even a quarter inch pim just falls out as soon as you let goe of it. I just need to put one new hole as close beside the dammaged hole as possable so shelf will stay in long enough to get it loaded, so used cases no chance to have a scrap piece to try the bits out on. Several cabinets and each has one messed up hole. but only about 3 holes total so cannot affored big money for a fix on 3 used cabinets. I have found that if you start out with too small a bit and then try the next size up it somehow ends up with that bit making the hole 4 sizes over size and I can only go about an inch to side of dammaged hole to put a new hole in. No place to just practice. Bits in box are not size hole they store in. but every bit in box of over a hundred bits are smaller than the hole they are fitted to and no none have been replaced to get the wrong size for that hole. These bits have never been used. Each cabinet wood is different on. Where they are going they don't have to match.

5mm divide by 25.4 = about .196 inch

(quoted from post at 19:42:32 12/05/1Cool Pick up a set of cheap digital calipers that have both inch and metric. Makes conversions as easy as pushing a button.


Ditto .

They are $10 - $15 for a metal caliper ( some are plastic / ? )

You can also measure your pin and zero out the caliper . Then any drill bit you measure will tell you how much bigger or smaller the drill bit is .

Pressing the in/mm button automatically does the conversion for you . Very handy when trying to figure out if a bolt is sae or metric .

A caliper is handy when drilling a hole that you want to tap , in a non critical situation . Measure the tap on the inside threads and zero the readout , then measure drill bits and find the +/- that you want .
