Please critique my profiler design

[hugocacola]

i have already tried bandsaw, router bridge, planner and even sander for core profiling.
As a i see it any of this methods would be accurate enough for me (except for the sander, of course) if i would be able to find a damn way to hold the core to a negative mold. Negative mold is my target, I think that results are better this way cause router or planner (worth to say bandsaw) are designed to make flat surfaces.
Of course, screws are a good option to hold the core to a negative mold, but why not triying vacumm?. I´m not trying to build something where the core has to be screwed or clamped, unclamped and clamped again to be held.

ummmmmmmmm, i´ll keep thinking about this tomorrow on the chairlift.
Please, some more feedback about vacumm will be highly appreciated.

Hello Chaca

i use negative mold at my snowboards and i dont need to hold them on the midle, put some screws on the edge of the tips to prevent the come back, nad excelent work come out from it... bad work only some times on the tips when the planner blades are not good...

i thought about the 40 grid sand paper and a negative mold holded...and a guidline for the cylinder...i gonna think on this ideas...

I´m planning to build something similar to this soon; springs look like a very good idea to keep router bridge in place. My idea is to build a negative profile mold so i can route flat. Guess i´ll need a huge vacum compressor to hold a 12 mm thick blank core to the negative mold. What do you think abot this?

This is how I do it, and I finally settled on using screws to hold the core down. I position them just behind where the taper starts on the negative profile. I found this to work the best so far.
