hey guys,
completed my first build this spring after reading up on things on here for a couple of months.
got to ride the first board (splitboard) and found that it actually performed (!) which led me to build a couple more.
started from scratch on a completely new design. it's intended to be lightweight pow split, with some added bells and whistles like magnetraction on both outside and inside edges. i made the design in illustrator (don't have access to solidworks anymore) but found that it actually wasn't that bad. once i had the shape and profile figured out i started playing around a lot with junksupply's ski-calculator to nail down my core properties.
i wanted something lightweight and decided to go for a core with a mix of poplar/paulownia. aiming for a stiffness that's about 7/10 and ended up with a 2.5 - 7.7 - 2.5mm core profile.
started by routing out the shape of the cores using mdf template i had made.
i made a core profiler (router bridge style) from laser cut mdf. got access to a smaller laser cutter at work, but due to it's size have to cut everything in sections because the laser bed is only 800x400mm.
moved on to the base. i mentioned i had decided to go for magnetraction on both inside edge and outside edge, and i had been sweating over how to solve getting a good seam between the inner edges. so i decided to make a separate jig for guiding the router for the inner edge. basically i started by routing the outer shape of the ptex and after (while still having the outer edge template in place) i put the inner edge router jig which have guide locations that mate with the outer edge template. i'll also have a mating spacer in between the edges to guide them for equal spacing between each other.
last night i got to put the edges on. i'm not 100% satisfied with the inner edges. i'm gonna have small gaps in the finished board. the main problem is that the ptex has moved and changed shape a little.
i've been rubbing my brain for a better way to do this, but can't seem to figure it out. curious if anyone else have tried this and gotten successful results?
so basically this is the current status.
next up is starting on the mold. i'm going to be vacuum pressing it and I've got all the material so just need to cut the profiles.
hopefully have the mold ready before the holidays.
that's it for now. i'll post more soon!
thanks to everyone who's posted here previously and helped me get this far.
