Nice rig! You might want to go with smaller but closer spaced holes for the vacuum table to ensure even holddown pressure.

PS: posting pictures of pinky&brain but complaining about other people posting off topic?! ;)

It ain't clutter. It's a compliment followed by a single question and answer.
Want every post to concern your planer crib, move it to a journal. That said....looks like your working hard. Good to see

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 in other tech. areas.

btw. it wasnt your post im complaining, no prob with little joke in betweeen (i posted the pinky stuff too) but when our is saska ;) guy starts explaining his history i felt it would go very off topic soon.

Anyways, never mind, wasnt a real problem :)

Peace!

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. Will see later if im good.


If i would do it again (maybe i modify it later) i would do the trust rails with really thick steel (5-10mm), the flat 3mm steel distorts a little bit with the screws. Were talking less then 0,1mm but for now it should be ok.


Doing the recalc of the spacers now and will try on real core afterwards. Hope i feel like brain after, no pinky. Or maybe better to be pinky? :)

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 approx 6mm everything is fine. Was the same without the new holes.
I tested before with a half shaped core, so i was i little bit overoptimistic.

Maybe i have to open the inner vacuum ports more (inside the crib) or i need a second shop vac.

At the end of the day it's only the last few passes treat really matter. So if it is holding well from 6mm onward you should be ok.

True. I hoped for a slicker solution, but good old hotglue is ok too :)

Hey Mammuth, none of your pictures work so I don't know how your hand planer solution looks.

I saw this today. Look at https://www.youtube.com/watch?v=vt0GutjcKZI
about 2:40

Is it like that?
