  • I don’t think anything you just said is correct.

    I cannot find anything about a tape format called “LP-2000” that came out in 1970.

    Phillips released the VCR format in 1972, and a successor Video 2000 in 1979. Most people on earth have not heard of these, because they weren’t nearly as successful as Sony’s Betamax format which lost the format war to…

    VHS. Made by JVC, Japan Victor Corporation, at the time owned by Matsushita…and/or Panasonic? Not Phillips.

    The first VHS deck was released by JVC under the Victor brand name in 1976, three years before Video 2000. If VHS is a successor to anything, it’s U-Matic.





  • The Leatherman Skeletool is currently available in several varieties, including the long-running standard model with an unfinished stainless steel body, a chunk of aluminum in the handle, and a 420HC semi-serrated blade, and the Skeletool CX variant with…whatever the black coating is made of, a carbon fiber chunk in the handle, and a 154CM plain blade.

    When the model was first introduced, the base model had a plain blade, and the CX had a semi-serrated blade. This was swapped, as they realized first time knife buyers were more likely to see the semi-serration as a value-add, while more serious knife guys would prefer a plain blade. So you might find a very old Skeletool with a plain 420HC blade, or an old CX with a semi-serrated 154CM blade.








  • 48" / 5 = 9 3/5" = 9 9/15" ~= 9 9/16" or 9 5/8". Dividing by five gets a little messy, but I divide by 2, 3 and 4 a lot more often than I divide by five. Thing is, that works out to be some pretty narrow doors, like, middle school locker narrow. You can indeed contrive scenarios where the math is ugly, but inevitably the cabinet you’d make would also be ugly. In actual scenarios you face in the real world it has a way of working out.

    I’ll give you a real world example. I recently built this dining room cupboard and hutch. The absolute overall width of the cabinet is 4 feet at the tabletops. The tabletops overhang the edges of the carcass 7/8", and the legs are 1 3/4" thick. So the area between the legs that the doors fill is 3’ 6 3/4" (4’ minus a total of 5 1/4"). The upper doors are 1’ 2 1/4" and the lower doors are 1’ 9 3/8". In reality each is 1/16" narrower than that to allow for some space for the doors to swing open and closed. The drawers have a 3/4" thick bulkhead between them, so each opening is 1’ 9", and the drawers are 1/8" narrower than that to allow a 1/16" gap on either side so each drawer is 1’ 8 7/8".

    The leg dimension was chosen so I could have two layers of 3/4" boards, one for internal structure one for the outer rails, doors etc. and still have the legs stand 1/4" proud to make the legs look like legs (which they are; they’re genuine posts) and to hide any impreciseness in fitment or milling of the rails, doors, drawers etc. The top overhang on each side is half of the leg’s thickness, and then every dimension after that comes from the plan of the cabinet.

    Tell me that wouldn’t have been a pain in the ass to do in metric.


  • Okay, a simple mortise and tenon joint. If I cut my board to 3/4" wide, if I want a tenon that is half the width of the board, it is 3/8" with 3/16" on either side. All my tools have these markings, I have router bits and such that are these sizes, easy. If I want a tenon that is 1/3 the width of the board, that’s 1/4" with 1/4" on each side. Also quite easy to find tools for.

    In metric land, they often mill wood, or manufacture plywood, to 19mm. Because that’s quite close to 3/4". Show me a half, or a third, of 19mm on a metric tape measure.

    You’ve got a 4 foot cabinet with 3 doors in it. How wide is each door? 1 foot, 4 inches. You’ve got a 400cm wide cabinet with three doors, how wide is each door? 133.3333cm.


  • There is, now, a separate problem where 2x4s specifically are made of very inferior lumber. most will have either pith or wane, and I’ve seen them have both, which means the tree they harvested is maybe 5 inches in diameter and they might have gotten 3 2x4s out of one log. Even compared to when I was in carpentry class in high school the quality of construction lumber has decreased. Larger boards like 2x8s or 2x12s don’t similarly suffer because it’s impossible to make them out of saplings. But still.
