    Calculating Hydraulic Press Pressure on a Skateboard :)

    ^Interesting vids, not sure I want to start down that road though :) I am able to apply more pressure (ergo receive more resistance feedback), with less creaking coming from the press. I've added 120kg to the top beam which is probably helping. I'm sure I could crank the jacks easily enough to...

    Calculating Hydraulic Press Pressure on a Skateboard :)

    Thanks jack action - I've seen everyone of those videos and many more when I was trying to decide how to do mine 👍 All seemed to have pros and cons, but I think I just had more of the materials to hand to make the one I eventually chose. The guys from the third image, their skateboard broke...

    Calculating Hydraulic Press Pressure on a Skateboard :)

    Hi all, So, I took it apart, took out the cross beam bolt in each corner and used joist hangers instead. (I didn't replace the split post due to not being able to source anything other than a full 8' length). The deck is sitting in between the blue foam sheets. So, back to the original...

    Calculating Hydraulic Press Pressure on a Skateboard :)

    With all this in mind - no need to replace the split cross beam?

    Calculating Hydraulic Press Pressure on a Skateboard :)

    Lnewqban - I didn't understand what you meant before, but now you have edited it it makes sense, thanks. I will probably attempt something like this. Once this is done, will this allow pressure calculation? I was initially thinking some kind of pressure registering material between two of the...

    Calculating Hydraulic Press Pressure on a Skateboard :)

    Hi all, just to give a bit more information to the above responses before I respond in case it changes anything: 4" Posts 1.75" Plate Thickness 10mm Bolts Clearer front view Clearer side view Clearer rear view Clearer view of bottom beam - this sits about 5mm off the floor as the bottom...

    Calculating Hydraulic Press Pressure on a Skateboard :)

    Thanks. I don't have chain, but guess I could use ratchet straps - if I need to invest more money I would put it into a steel one, so if fixing/reinforcing I need to do it with what I have. Didn't think of gluing the wood first - would 4" glued faces add sufficient resistance? Once done - how...

    Calculating Hydraulic Press Pressure on a Skateboard :)

    I eyeballed it - I knew it would withstand enough pressure to compress the deck to get a solid form (it's 7 x 1.5mm of maple veneer glued), but now wanting to remake the mold, and possibly the frame, I'm trying to determine how far off of the 2 - 4 tonnes I might be. If I'm nowhere near, I could...

    Calculating Hydraulic Press Pressure on a Skateboard :)

    Hi jrmichier, The surrounding frame is constructed of 4" fence posts. The frame starts to creak as their capacity to withstand the pressure is reached. I am sure there is a degree of bend in the top cross piece, but it is not instantly noticeable. I have not noticed an issue with the bottom...

    Calculating Hydraulic Press Pressure on a Skateboard :)

    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...
