On my first ski the vacuum pump started every 15-20 minutes. On my last one like described. Using a normale weisse Küchenarbeitsplatte, these rubber stripes from hp and a foil from rg. U hear really small leaks if you go close with your ear. My vaac pump (venturi system) with the tank holds the vaac...

The power stuff is pita. My compressor blows the fuse from time to time so its gambling... But 15 minutes should be no problem. On my last ski the vaac was going down from 25hg to 22hg in 40 minutes! I have a vacuum tank with 50 litres (or 25, dont remember) in between, that helps too. But 0 in 15 m...

You had a good dump in Cham, no? What better conditions? Too much wind i guess, same as here little bit more south

Cool, danke!

Phosphated metal is a good base for painting. Any ideas or doubts if there would be any problem with epoxy bonding?

Shaped 2 cores, worked very well. Chris, this is for you, approx 150-200 holes more ;) But unfortunately it didnt help. My raw cores (12-15mm, most with "camber/pretension" already) dont get sucked down. The ends are lifting. A little bit of hotglue helped. When the ends are planed down to...

So back to topic ... LOL ... Tests look promising. Did work on this "i do a quick modification" yesterday till 4 in the morning. The holding force of the holes is very good, need a lot of pull (almost impossible) to lift the core. I have smaller holes (5mm vs 7mm now) in my ski vaac table....

He did some time ago already ;) Didnt want to sound rude but i did read almost the whole forum in the last year and its always a pity if you have (maybe) interesting threads where the information is hidden between lots of offtopic. Maybe im little bit too sensitive cause of lots of forum experience ...

HPVC 1 is born .. HandPlanerVacuumCrib

Doc, thanks this was the Article i did read!


Sometimes its good to sleep over a problem, will rebuild my crib for my hand planer setup with vacuum. Think it will work. Pics will come later.

My current setup is a vacuum bagged cassette with a hybrid press former i.e. no external pressure from a hose or alike but the cassette is pressed to form the rocker/camber etc... built into an oven. The oven is nearly finished now I should have the first board off the mould in a couple of weeks. T...

With this type of crib you need a roller to push down the core, no? With hand planer you have to push it down? I planned the other way round because i had troubles with the crib (which worked same way like yours) and planer. But you bring me to an idea! Instead of cutting the rails i can reuse my cr...

Regarding the sanding. I did read somewhere (here?) that a core out of the planer is better for bonding then a sanded one. Had something to do with clean cut fibres vs. more closed structure when sanded.
