I could do the calculation for you if you want to. Will take me after work so will be tonight. guess this works at least. What materials are the beams made off? that would be awesome!! it s steel i think S235JR or S355J2 (before 2006: St-37) i don t know if this is the international code, but it s ...

ok thanks, i ve fixed that gap. will there also be the need of some ribs, like most people do with their presses made out of rectangular tubes? just from your experience: what deflection may i consider with this beam construction (the one below)? will be 1mm or 1cm? and is it negligible or not? so, ...

hey, as i found some remainding i-beams in a metal factory, im finally going to construct a pneumatic press. it s a couple of "HEA 160" beams, i dont know if you can deal with this code. check out the attachment there s more information. please check the press and dimensions according to s...

polypropylene?

...yes, polypropylene

it seems all of you using mdf as material for the base templates. i made all my templates out of pp, it s more durable i thought. now i m wondering if this vacuum method to hold down the base material would also work with a pp template? pp has not the rough structure compared to mdf, might that be a...

just one day in the snow, but already some damages: 1. the top glass layer on one ski delaminated in the tip spacer area. its only on one ski, the other ski layers stick pretty good to the abs spacers. http://lh6.ggpht.com/_9K0V5_qTv6Q/S8tELFZ6vbI/AAAAAAAAAJ8/BbUoO7xb_bE/s640/000_0096.JPG the glass ...

Did you say it was just the top layer of glass with a varnish?
And you might want to ask lucacasty(leaf skis) about what kind of varnish to use, he uses it on his skis.

...yes, it s 804grams triax on top with a basco varnish

after one day in various snow conditions, the ski turned out to be a really rockable fun machine. surfing powder, it floats like no other ski i tried before. the sidecut allows accaptable rides even on hardpack stuff and slopes. the softness of the ski is very forgiving mistakes. turned out to be a ...

just talked to friend of mine who builds longboards (skateboards) for downhill racing.
he had exactly the same problems while using sicomin 8200... so pretty sure it s the resin combined with that ligth fabric
