Hi all,
I wonder if someone can help me with a calculation/estimation?
I have recently built a skateboard press to...press skateboards!
My question is, how do I calculate how much pressure is being applied to the skateboard?
Most presses are steel, however, not having any metal working skills I have made one out of wood.
General advice to press one deck, is applying 2 - 4 tonnes of pressure for x hours
I am using 2 x two tonne bottle jacks and a scissor jack, but as the pressure applied increases the wood starts to give.
Is there a very crude calculation or estimation which can be derived from this - the deck is sitting between the two molds?
