I haven't posted anything in a while but we have been working quite a bit on this project in the last few weeks. So i ll give a quick update. We decided to give the router methode a try after we had some troubles with the planer. We build a router bridge with a vacuum table. Kingswood style. Here is...

I know the topic is quite old but i got some question nevertheless :) I like the idea and design of this adjustable mold but there is one thing i m wondering about. What is the difference in height of the different spacers you have?. Is 1mm fine enough to build a smooth mold? It seems like you need ...

@Akiwi: Almost. The Planer there is not wide enough. We went to HEi for that. But its pretty expensive there and I dont know how good the planer(i.e. sharp blades etc.) really is. Besides that, we got everything we need at the WerkBox3. @falls: By the research I have done on UHMW it seems like it is...

@Akiwi: we are at the Kunstpark @falls: thanks for the input. we might try that. another problem which occured(and I guess is pretty common) is that the planer eats the sidewalls. First we thought ABS is even worse than UHMW as it is harder and the planer just ripped it off on the first pass, right ...

Hey guys, the idea of building a snowboard has been stuck in my mind for about 6 six years now and since i’ve been reading in this forum. So first off, I have to thank all of you for this great resource. Beginning of this year me and a buddy finally made it and found a sweet spot for rent and build ...

That low tech version with MDF spacers or similar looks like good starting point. Keep you updatet on the process.

@rnordell: Are there any advantages of using heated oil/ethylene glycol than a heat blanket? Why the extra (expensive) work than?

yeah, i'd do some testing for sure and it was a quick and dirty calculation to get a feeling for it but i guess it s not too far off. the force on a square cm isnt that huge. but the question remains. what amount of deflection should one aim for at least? @rnordell: what kind of jacks did you plan t...

I understand. But if you look at the langzauner mold where you form the camber out of ribs you always get a deflection of steel sheet on top in between the support jacks. The only thing one can do is to minimize it by using a thicker sheet/decrease the distance of the ribs until its not detecable an...

in order to compute the thickness of the steelplate and the distance of the jacks in a langzauner type mold: what would you consider to be an acceptable amount of deflection in between the jacks? in other words what amount can be cleared up in the finishing process to get a dead flat base?

cheers

sounds like a project, any interest in sharing the plans?

Hey guys, I ve seen a couple of videos/pics where they (it seems to be so) use a fully adjustable bottom mold in a press. These are the videos: www.youtube.com/watch?v=GUWvdTMjr6I at 1:15 A similar construction seems to be used at Burtons www.youtube.com/watch?v=546v1-rLftE at 2:28. A different appr...
