Cutting base material - ptex

Shif - good idea. I never thought to keep the p-tex bases attached to the template while applying edges. I give that a try on the next pair.

Thank-you for all the help. I cut out my first set of bases today. I used 2 sided carpet tape to hold the ptex to the mold and then cut it with a router.
I will try to post some pictures later.
The information provided was very valuable.

thanks again

I watched some printed bases wrinkle like shrinkey dinks in the oven, when i pulled them out the box and laid them on the template.

No more crown clear subbed for me, shit sucks!!

IMO it's critical that you keep your base material at the same temp after it is cut out. Also there should be little to no time between cutting out the base and gluing the edges on.

Ideally this is the absolute last step that you do, so that you have little to no time between cutting out your base gluing on your edges and laying up your board.

Yep, get all your ducks in a row.
All your materials ready, I usually dry fit it all to make sure I have everything ready to go and no surprises. Glass cut around locators etc.
The one time I didn't do this I forgot core locators and ended up stapling my core to mold midway thru the layup.
Then cut base, glue on edges, into mold and start mixing.
This has been my method since day one and so far not one banana ski.

Big router table, that's more of a shaper.

OK, shaper. Didn't know about there was another name.

I just quick translate it from swedish. (My swedish)

And...I haven't got any of those messages. It works like before...

All I can say is I'm truly afraid for your fingers Jan...all it takes is one little slip.

I know, i know, I considered it, but I don't have any other trick for the moment. And the result is perfect.
In the wait for a cnc (which doesn't solve the warping issue) and a proper(professional) casette. This will do... I will create some sort of push stick. Now I know! Maybe an update next week??

A proper cassette solves all warpage issues as well.

Also, it's critical that your edge is not forced into shape on the tip and tail. If it is as soon as your base is heated up the edge will deform it.

I've just been using a dragknife in the cnc cutter, that way I cut out my inlays in the same sequence. I've actually had no problems yet with the warping you guys are talking about <knocks on wood>.

And yeah, the Galleria base is tricky. If you leave it in even a couple of minutes too long you'd have a straighter base if you made it from lizards and sharp sticks.

Much less common with snowboards, but I guess you're building little snowlerblades

anyway.

Have you checked your finished blades against the template? You might be surprised.
