Hi,
Are there any major skateboard manufacturers pressing decks by vacuum?
I think I heard Skate One does this.
What are the pros and cons of laminating decks this way?
I havent seen to many setups that use vacuums...im assuming its for a reason?
Thanks for your response! |

Skinny,
so this "airlam"...is this process exclusive to skate one manufacturing, or readily available for the average joe? Are there any pics to view this set up?
Thanks a bunch for this info. |

If you are interested in some more info about vaccum bagging here is a link that explains in great detail of how to build several types of vaccum generating machines. The author gives an overview of the whats and whys and a large range of useful information.

The reason most manufacture don�t use vacuum for lamination is you are limited to the atmospheric pressure and that is 14.7 pounds per square inch at sea level. I believe there is a do it yourself skateboard kit that uses a hand vacuum pump. I wouldn�t recommend using this because of the pump. You need a good vacuum pump to come close to reaching the 14.7 Psi.
We developed our own pneumatic press. It creates even pressure over the entire surface of the board and eliminating veneer thickness variation problems. It is not as efficient removing air between layers as the vacuum however you don�t need external air pressure for multiple layer laminations. It is relatively simple and doesn�t take much maintenance. A vacuum bag with an air bag or bladder for pressure is the ideal setup. That is basically what the space and aircraft industries us for composite parts with an autoclave adding the external pressure.
If you use the vacuum bag technique, (there is a lot of information on the internet). Just do several layers at a time. A good vacuum pump will remove all the air between the layers and you will have a really strong skateboard. Obviously this is not practical in a production environment. You can also use the vacuum bag technique to dye veneer all the way through the wood. Just make sure you don�t use a water based dye (it raises the grain and doesn�t penetrate the wood surface). The veneer suppliers use an autoclave to remove the air from the veneer then introduce the colored dye.
Good luck. |

I don't mean to dispute the knowledge of the previous posters, who certainly know more about board building than I do, so just take this as a single data point to consider.
I used the roarockit kit with the hand pumped vacuum bag. I made a pintail long board with a tad bit of concave, and a street deck for my son with what can be described as typical modern street skate amount of concave and flipped up nose. Worked just fine.
Just about any shape can be done with vacuum bags. Reallly good method for laminating surfboards too! |
