Default The utter stupidity of Imperial measurements

especially where template guides and cutters are concerned. I asked Jim's advice as to what guides and cutters the average amateur routologist would be likely to have, so that I could produce another tutorial for beginners that was truly done the "American" way. Jim drew my attention to the fact that he couldn't find any metric guides on the net, so, not disbelieving him, but curious, I did a Google search with similar results, I did however find these two sites, the first offering a kit which contained both a 51/64" and a 1" as well as a 3/4", the last two of which I was hoping to base the next tutorial on, but the 51/64", how many of you have the means to measure in 64ths let alone calculate off-sets! I think that this unusual figure is close to 20mm and the 1 35/64" that I've seen several times is pretty close to 40mm, there we go, the wonderful 40mm guide that I'm always using. The second site actually sells a 40mm guide!
To those members who are/have become bored with my constant pushing of metric measurements, tough titty as an infamous follower of some Maharishi or other once replied when being interviewed on TV!
For members who can see the advantages of metric guides and cutters, make it known to retailers, distributors and even the actual manufacturers, or if you can't wait that long, perhaps you should have a go at OakPark, our sponsors who, I believe have equipment capable of making template guides! Have a good day my friends and fellow members.

Not to mention material sizes like 4/4 (four quarter) which starts out as 1" rough sawn but is closer to 13/16" after both sides have surfaced & still labeled 4/4. How about 1x material that actually measures 3/4". It can get pretty confusing.

Just a thought,

Skilled engineers, using fractions and inches, as well as a slide rule or two developed everything from modern medicine, farming, aviation and space exploration. These enlightened engineers, again using fractions and inches, even put a man on the moon.

Possibly your difficulty with tried and true measurement scales is actually a training deficiency.

I will say, it's completely pointless to hound one company, or one set of things to be completely different than everything else. No point having one tool use metric and another use imperial.

And the entire tool industry isn't going to bow to pressure from a handful of people. Waste of time. Even if they did, you'd have to go after the lumber industry next.

Measurements are measurements. It really doesn't matter what I use, as long as I use the same one from piece to piece. While it would be nice to have a base-10 system for everything, it's not going to happen. Much bigger fish to fry.

I don't doubt for a moment what you say but here we are not professional fine furniture makers, the majority of members are like me, amateur woodworkers. Many of course are professionals in other fields, like dentistry, electronics, electrical engineering, mechanical engineering etc. But, it doesn't alter the fact that in routing, template guides and cutters are are so much easier to calculate off-sets which is an important part of advanced routing. As a matter of interest, how do YOU measure a 51/64" template guide?

Chris, with routing, it doesn't matter what size the wood is, it can be sawed, go through the thickness planer to make it an exact size, whether this is Imperial or metric make no difference, but when deciding on cutter and guide sizes, they are fixed and and one has to choose the fixed sizes of these in order to calculate off-sets which for many projects can be critical, that being so, how is the average member going to deal with the likes of 1 35/64" and 51/64". Correct me if I'm wrong, but my feeling is that you haven't actually experienced plunge routing using templates, male and female.
