Is it possible to make skateboards on a large scale with zero loss from warpage?
For many many years I would have told you no. Absolutely not possible. Even the best shop has some loss right? I am starting to belive it is an eventual truth, that a shop handling 1000's of decks a week can operate with zero warpage loss.
The funny part is that there is no magic fix that allows this to be possible, no super press, or glue. In fact my soultion came in the form of a simple process change. I don't have any numbers yet, but lets just say that I am batting pretty high. I am also working on long term data, well after the deck has been skated for the first time. I think this might just work out. Wish me luck. |

Good luck. But remember, sometimes it has nothing to do with the pressing, sometimes it's just the wood, sometimes its temperature and humidity changes, sometimes it's the glue or glue coverage, sometimes its contaminants. Tall order to lick. |

I am prepared to accept the fact that wood and glue will never conform 100 percent of the time. This could be the end result. Wood is a living material and has a mind of its own. Glue is unreliable at best, when you consider that wood glue can come in 2 parts, and one part blends of glue, and catalyst. With resins you can measure out materials and come to a close combination, however the factories making the resins will tell you that nothing is a guaranteed mix....every mix ratio has plus and minus varients from the factory.
With 1 part glues, who knows how much variation in catalyst can be from drum to drum, batch to batch, gallon to gallon.
I think the key lies in knowing the catalyst in the mix you use.
I am hoping thats whats up anyway..... |

Very interesting, love to hear the results, but I would figure it would be a trade secret. |

For 100000.00 i will tell you how to build warp free skateboards. i will also refund you 5.00 for each deck that does warp using this method. its not magic glue or super wood. |

I know this is not feasible, but has anyone ever done a deck out of a solid piece of wood and have it CNC shaped/concave all in one shot or done manually of course? |

Indeed. A lot of people don't grasp that. |

is your question based on in the wood shop warpage,
or end user warped boards?
if you use the correct glue,
applied in the proper way ( glue spreader )
press for the proper amount of time, and pressure,
you have the first part.
next is what you do with them after pressing, before cutting.
how are they stacked, face up or down?
that moisture level must be correct before you cut them,
then after cutting they should be sealed within a few hours.
humidity control in the woodshop is a huge part also.
we dont get much warping here in PA.
and word back from customers is the same.
a few here and there, maybe 1% or less. |
