Hi @der_On, where are you located?
Here, for example, two random online shops in Germany:
Btw: Do you have a photo of what kind of quarter+curb you look for?
@skateboarding I'm in Leipzig. Actually I'm looking into something like this: https://vestringandson.com/product/shredbox-quarter-ramp-2x4/
It's small enough to be carried on a cargo bike. However I would prefer it to build myself, as it's a bit pricy. Currently trying to build a 3D-concept that allows dissasembling it's flat part for transport. My major concern is durability and weight.
@skateboarding In Leipzig we have some skate spots with quarters but they are either very crowded and some even far away. So the idea is to have a mobile one that we can take to any flat place that is not crowded or even use it in the backyard. I think in combination with a DIY grind-box our little skate crew would be uber happy.
@der_On The Shredbox looks nice, but seems to be quite expensive (like my links). 479€ for 65cm height is much.The cost of material for a quarterpipe (65cm x 125cm width) is much lower. You get good screen printing plates (Siebdruckplatte) at 25€/sqm & they ride well.
Did you ask the Shredderei whether they know a carpenter who builds quarterpipes? The https://www.shredderei.com has an own woodshop, maybe they know.
BTW, here's a construction manual for quarterpipes:
@skateboarding I'm making progress with the 3D-model. I've gone for a smaller 41cm height quarter and a 85cm transition and only 62cm wide. But with two of them combined it can become a 124cm wide quarter pipe or you can place the small quarters facing each other to get a mini ramp. The back part of each can be removed to make it even smaller for transport. Everything is put together with screws and nuts.
@der_On Nice 3D model! I just wonder whether the transition is too mellow and the top (just under the coping) is not steep enough. This might make lip tricks more difficult. With other tricks you might still have too much forward momentum at the top (the angle at the top is more like you have in a kicker / jump ramp).
E.g. the Titus example has more transition and ist steeper at the top: https://www.titus.de/blog/news/wie-baue-ich-eine-quarterpipe/
@skateboarding yes. I had the same impression. I used the same radius as for the 60cm height version. I have to find a smaller radius that works.
