Quoted from Coyote:Wht's the main cause for warpage? Humidity? Storing it wrong? Or just the wood used?
Also wow, that ink on the text is really, really blown out. Huh.
Fixing the print on the inserts would cost a fortune. I am proposing making the inside edge of the black key line a size smaller, to cover the cresent from the alignment issue.
as for warping gravity, change of temp and humidity, and cureing/drying to its final stage are the causes of warping. The warping that wtists the pf is my greatest concern because I cant fix it with gravity and weight. as I have described before when plywood twists, it is because one of the opposing forces of the plywood is weak. Either a big split in the wood, or often there will be some wood used that is partially bark, and has no lateral strength.
If you look at any board stock like a 2x4 or 2x10 whatever, it is crowned. or I like to call it smiles. every single board is curved. The good wood not much. A good carpenter always considers the crown of his wood as he/she places it. When I make my beam to hold up the roof soon, I will screw together 2x8 and I will make their crowns oppose each other. I will also put a peice of plywood in-between them.
So plywood is made so we can have "flat wood". each layer of the plywood has its direction, and the next layer is set in the opposite direction. The more layers you have the less quality wood you can use, because its thinner pieces, and having more of them makes the strength of one bad one not much. So a twist happens as the wood is doing its final cure.
Almost always there is not a problem because they design the pf to be held, dealing with plywood warping, but also because of the weight of the parts attached to the pf, easily push it flat.
Its scares me because if I clear it when it is really bent, and then it gets straightened in the game, there is always going to be stress on that clear.
Lately mirco pfs have been arriving warped. I think its because of how they are packed, as well as the change in temp and humidity during the travel so far. Its always more dramatic in the winter. right now in michigan, its been cold and wet for 3 weeks, then we have artificial heat that goes up and down.
So much for my coffee break, I didnt realize I was going to write a book, but a lot of people freak out about it. I do. Except for twisting, its almost always fixed by me rotating how they lean.
