A quick heads up. I've just come back from the blue big box store in search of some project plywood. They are now selling plywood that's about 50mils thinner than standard English sizes (0.0702" compared to 3/4"). While it probably doesn't make a difference for most home improvement projects, that's a big jump for Z. Mark
Is it actual plywood or a paper thin veneer on top of a couple of layers of fiberboard? If it's marketed as finish plywood and it's from blue or orange, it's likely not real ply (multiple crisscrossed layers of thicker veneer).
Two quick questions: 1) Why would it make a difference for Z or any other scale? (How are you using it?) 2) Why not just say Lowes or Home Depot? :question: ...maybe I just need more Coffee....
Personally, when I'm not in a charitable mood towards a company, I often don't feel like increasing their search engine rankings again even by the microscopic amount of a single post.
All, It may not be that big a deal, but in my case it means each module would be 0.1" shorter than planned, I have to have to watch that I don't mix 1/4" with the .220" deck and the supports need to be 50 mil higher for that deck. Additionally for me at least some of my woodworking jigs, based on a 1/4" grid won't work. This is not a paper or coating on a composite material, its just plain old laminate plywood. Robert, I thought about metric, since that's what happened technically with 2x4s a long time ago. But at 18.6mm it seems it would be an odd standard. Rob(A), Because I find I frequently unintentionally run afoul of some of the named brand rules here (much to my subsequent embarrassment) I try to never name names. Also, I don't know if this holds true for plywood at the orange box. Mark
This is nothing new. I am a professional cabinet and furniture maker and have fought this problem for 20 years, it can be a regular pain in the***. Now I need 2 and sometimes 3 different router or shaper bits just to cut a simple dado to fit the "new" metric sized plywood, They claim it's because of metrics but 3/4" is .750" is 19MM (really .748") but close enough for wood. I believe it's just an excuse to save money in manufacturing.
What I ran into lately at HD is that everything is measured in 64ths of an inch. The 1/2" sheet of plywood was sized at 31/64ths. Being a machinists I can measure 1/64th and when asked if I needed help I inquire about the change and the 20 something guy said that's the way it's always been and said look at this it's a 1/2 inch exactly. Yah! Except the scales markings were both outside the width, making it 2/64 undersize. It's a whole new world out there. Get used to it.
If the wood is Canadian wood that would explain the metric, and a lot of wood in the states is Canadian wood.
Couldn't you just add that .1" to the legs? And every modular layout I've ever been a part of has adjustable legs, so that .1" should be a simple half turn on the adjustment feet.
