    Due to the number of pm's I receive I have decided to make a small blog to keep all the info in one place and share the stoke with other people interested in building their own snowboards and skis.

    In short I started building my own boards last year as I could not find a board that was everything I wanted. I knew nothing about building boards but decided to see if I could do it, after all it couldn't be that hard right? [​IMG]
    I built 5 boards for japan, each one exactly the same but with different core thickness so I could work out which was my favourite flex, being a bigger guy I ended up enjoying the thickest one the most..

    Below are some of the boards from last season

    and in action


    Fast forward to 8 months and I am back at it with some new shapes and new methods.

    New shapes

    New molds

    Bending some edges

    CNC side cut radius templates. Last year I got the whole board shape CNC cut which was a lot of work drawing it up on cad and its not cheap getting templates cnc routed. This year I am drawing my shapes by hand using these templates which makes it easy to create one off boards and funky shapes etc.
    Most snowboards have a side cut radius between 7-10m. Most skis are much larger at around 20m or so. I am experimenting with ski like radii on my boards as I am looking for response while carving at high speed over agility at lower speeds.

    I have never had a core cnc cut, only a complete snowboard template from MDF which cost $100. Well worth it for multiples but not for one off designs. The cnc radius templates cost $110 and will serve me for years to come

    Cheers guys.
    I scored a heap of new guinea rose wood for making my veneer top sheets this time. It has some incredible colours in it, purples and stuff, so I cant wait to see how they come out

    Bob have you got any pics of your press while you are pressing a board. Was considering having a crack at a set of skis...

    This is a pic of the press the first time I pumped up the fire hose, there is no board or cat track in there but it gives you an idea.
    Ill let you guys know when I am doing a lay up one day and you can come and have a look.

    That'd be real cool BG. Am spending much time reading all at skibuilders.

    Can't get my head around whether to go down the steel press route or plagiarise your model. Any likely issues with yours over the longer length of a ski?

    My press is 205cm internal, all the boards I have made so far are 180cm so its about the same as most skis I think.
    The only issue I had was the first one came out with a convex base so I put some square tube laterally across the bottom of the press. Problem fixed.

    The reason I built the ply press was cost and size. It cost about $200 and can be packed up for storage or moved easily.
    A steel press costs a lot more and is generally more bulky, but if you have the room and the money to spare there is no reason not to build one. Probably the biggest problem is you dont know exactly what you want in a press until you have used one.

    Haha no that is my workshop.
    I built my first 5 boards there but I have moved it all home recently where I have a small but dedicated space.
    It was a pain having it all at work where I had to pack it up all the time

    Yeah it does.
    In fact any size hose will as long as you dont inflate it past 50% of its diameter. You could use 2" hose if the gap between top and bottom molds was only 1".
    The bigger the hose the bigger the gap can be which makes life easier especially if you have a steel press where the top and bottom molds are fixed

    Step 1: Set somoeone's house on fire.

    Step 2: Take a big pair of scissors to the local fire station after they hang the hose out to dry after putting your fire out.

    How often do they have to replace their 'old' firehose. Maybe they have some old hose lying around the station they could let you have a couple of metres. Otherwise, see Step 1.

    Or you could just go to a irrigation / water hose type shop and get some high pressure lay flat hose, its relatively cheap and works great!

    I have seen that hose online, the red seems like the heavy duty stuff and the blue is light duty.

    Thanks plowking!
    I will be spending a few more hours on it tomorrow, profiling the first core and also ripping a heap of timber to make the veneer top sheets

    what do you do to profile the cores, did you make a bridge setup and use a router or you using a thicknesser and a support to set the angle.

    Looks awesome Bob. It's got some epic float when comparing it to your 2012 vid. Would love to have a look at it if your still in Nozawa when I'm there. Thought you might find this interesting.

    0.5mm per pass. Takes about half an hour . I got the first one done today and spent about 3 hours ripping strips for the veneers.
    Im buggered.

    Looks sweet Bob.... have made my bladders for my press and pressure tested them to 100psi so far with only minor teething issues to start with.... hoping to have a press up and running before Christmas (I am building a I beam press...)

    Ive used 5 inch lay-flat irrigation hose.Its the blue stuff and I know that ppl say the colour relates to strength but the hose I have is available in 4 colours all same pressure rating of 158psi The only reason I have used this is cause I acquired it for free and the blue stuff is what my mate could get straight away. I will be doing a full day pressure test (12 hours) this weekend at 100psi (Way above what I plan to press at.) on the weekend, If all goes well mate I will have enough for 2 more bladders If you are happy with it (I was given a 10meter box/roll)

    Sounds great - will stay in touch! If it tests fine I'll happily buy some from you.

    as long as it holds 100psi for 12 hrs (well within the product specs) mate ill give you enough for 2 bladders.... It will just sit in a box in my garage taking up room and with the ski press and the car projects at the same time the missus will kill me if i keep hoarding stuff
