To all,

Yesterday I received my 17 pc Metric set of Thickness gauges from Woodpeckers. I love these gauges and find that they are extremely helpful in defining if my set up is correct and just generally help speed me up without cutting corners. In case you are wondering how I could do all of that since I received this set yesterday, I have had the Imperial set for a couple of months.

However, the question is this. Within the Metric set the 17mm gauge has been skipped. Right now, at the upper end, it goes 15, 16, 18, 19, 32mm. I cannot personally say when I ever used 17mm for either a dado or the board that fits in that dado.

So, what do you all say? Is the 17mm needed or not. Richard does not remember why he left it out, so we agreed to write here and ask everyone.

Fred

17 mm is pretty close to 2/3 of an inch...?

...and we all know how ubiquitous those .666667 gauges are......

In fact, one of the closest standard sizes in the world of metric and fractional is the SIXTEEN mm, rather than seventeen. In many tool sets sold in the US, the 16mm size is omitted, as it comes to 0.62992...., thus is 1.008 times 5/8" and well within tolerance limits of most nuts and bolts.

So.....the mystery why Richard's set omits the 17 rather than the 16 remains unsolved!

Gents,

You're thinking down the wrong path; an imperial set is already available, so there isn't a need to have close metric gauges. Most likely 17mm isn't a size that people working in mm need.

Best,
Rutager

32-15=17?

Well, actually 17 might be useful. That's darn close to the thickness of freshly delivered Home Depot 3/4 aka 23/32 plywood when first delivered out here. Of course, a week later its about 16.5mm in most places.

Jesse,

I can solve your problem. Move out here or down into the deepest, darkest part of the south. Of course you must bring your plywood with you and it would be best if you brought it after it hit 16.5mm. Around the Philadelphia area within a few hours our humidity can bring you to at least 18-18.5mm. On the other hand, head down to Georgia where Ron Brese, Shawn & Monica Russell are located or into Mississippi and you can probably reach 20mm. But ultimately you will want to go to New Orleans where you will be able to actually DOUBLE the size of your plywood to 33mm. However, whatever you do, do not try to now split that piece of plywood into two pieces unless you do not mind everything get extremely wet. You are welcome for the help.

Fred

Poto, thanks, but I don't think my math aptitude will outweigh my marks in social skills.
