Re: Which fiber is best at retaining screws

Unfortunately I have no data on the pull-out strength of those fibers. I think flax could work well too as the laminate usually stays relatively thick in a layup which would give the screws more material to bite into. Other than those fibers the ski industry often uses titanal plates to reinforce th...

Re: Splitboard "tounge and groove" concept

As for this tech being a meaningful addition to splitboards or just marketing, a friend of mine rides one of those Furberg splits (after riding Jones for a long time) and swears by it - in particular for hitting backcountry jumps.

Re: Splitboard "tounge and groove" concept

I am thinking about doing the same. My initial idea was to make the tongue out of a thicker sheet of composite (probably carbon fiber), however I am concerned that the carbon fiber will get too beat up during skinning with the risk of not being able to assemble the board for the downhill. Do you hav...

Re: Sublimation warping

Some waviness is to be expected especially with base material. The only way to mitigate this is to cool the material under pressure. Many snowboard companies just clamp the base material between two thick metal sheets to cool them flat. The pressure for sublimation sounds really high! I sublimate at...

Re: Design Software for Mac

You can try running a virtual machine with windows to run Windows specific software. Other than that there is native CAD-software for Mac too. A friend of mine uses Rhino for Mac to design skis.

Re: Skis... with a TWIST!

I would definitely ride them. You'd be amazed how many similar defects are in retail skis/boards and they are still sold in stores.

Even if you can feel the twist in one ski, your skiing will probably adapt to it pretty quickly.

Re: Honeycomb core/Prepreg Film

You could also use pre-cured fiberglass or carbon sheets. These could easily be made by just vacuum bagging or pressing single or mulitple layers of cloth on their own. If you want to save weight, you could make a pre-cured sheet thin fiberglass veil and use that as a separating layer. For better bo...

Re: Powderboards - season 1

Most people just tape them together with packing tape on the running surface side. Make sure to use tape that is as thin as possible as it will probably leave an indentation in the base which you will need to grind flat after pressing.

Re: Materials suppliers

I've had good experiences with junksupply in the past. Mirsad, the owner, is usually very responsive, but I assume his shop is a one man show, so it might take him a little longer to reply at times (or your mails are going to his spam folder). Have you tried sending him a whatsapp message as suggest...

Re: Bamboo

If you let us know where you are located, someone might be able to help with suppliers in your area.

Alternatively, you can always order a full container from china ;)

Re: New press bladder design

Leaks at the ends are usually due to your clamping material deflecting too much. At certain pressures you will need a pretty beefy piece of steel to hold the force created by the bladders. As for the connectors, have a look at the Happy Monkey Wiki. His method has proven to be somewhat of a "best pr...

Re: Jonrezz’s Build Log

Try the modified tile nippers for bending edges. Cheap, quick to make and works well.
