Forums DIY and Mods What plastic for DIY hardboot mod Viewing 5 posts - 1 through 5 (of 5 total) Author Posts March 22, 2018 at 5:38 am #817630 NorwegianDan 109 Posts These days, many boots are made out of grilamid. Sofar had no success finding a source for sheet grilamid for my own DIY hardboot projects. Looking for an alternative plastic which I can use to make my own cuff designs. Found these: plastics intl and these: the plasticpeople Beyond me which of these (if any) could work. Any ideas?

The plastic cuffs are all molded into shape with liquid plastic and molds are heated pressurized big expensive things. I think the direction for making your own parts like a cuff is to use fabric and epoxy resin into a mold into a vacuum bag. Still pretty time consuming, but not very expensive. Do some searching for videos on vacuum bagging parts and making molds. There are a lot of videos about resin infusion, but it would be overkill for starting out, hand layup or wet layup is fine. Composite parts don’t have to be really stiff carbon either. you could use all fiberglass or one or two layers of 6 ounce 2×2 carbon with layers of E fiberglass or innegra or something like that on the outside to add flexible durability.

As opposed to a strap which only pulls. Wasn’t planning to make a complete cuff, just parts. Something like the inner part of the dynafit highback. Those kind of things. For creating new cuff the easiest, before laminating your own epoxy and whatnot is probably to chop other boots. March 23, 2018 at 8:19 am #817673 Scooby2 612 Posts Oh I got it, agreed.

I feel it should be taller, but also some sort of adjustable stiffness would be really nice to have. Remember the ca. 2003 Burton Missions, which had changeable rubber parts on the highbacks? Something like that. Also, ofcourse, forward lean adjustment could be incorporated into the middle part. I´m just too lazy to get anything done 😀 I don´t feel grilamid is the best option in general, it´s just what we have available now. I can definately feel it getting stiffer in cold. Although, I would guess the middle part is not even grilamid, just the lower shell? I´d have a look on 3D printing, not on the one at the local library, but proper industrial stuff.. https://www.designnews.com/design-hardware-software/3d-printed-plastic-parts-are-strong-aluminum/186774327045346 Viewing 5 posts - 1 through 5 (of 5 total) You must be logged in to reply to this topic.
