The Shape Shack / Re: EPS Breather layer....Pono jrandy?
« on: March 11, 2019, 07:43:58 AM »
OK i did use EPS sheets as breather layer....and it can wrap rails as the vac comes up, it bends nicely....

For flat stuff it's ok....maybe really good, certainly looks good and clean....  but  while it will wrap a rail, initially it's stiff and flat, so when it begins to wrap, it overhangs the vac bag and then folds down on top of the bag making a crease in the vac bag as it folds  (top of the rail...bag pleats in)

But it definitely bends well...didn't crack/fracture...handled a 3" rail with good bend

So if it's 1/4"  on flat it's good, but i would only use it on a vac table and a half rail type bend...I was using a true bag, and couldn't keep up with the pinching....pulling the bag down wasn't easy as the vacuum  needed to bend it pulled the bag in too quick

  You can fair a clean line with the CF, but those fibers are stronger, and yeah they can be a bit more brittle.  so some may lift   The weave is too big won't be super straight   If you do go that way imho a  finer grit, and wear a mask.
  I still dont think you are seeing get the whole glass veil's just sacrificial will help hold the CF down and fill some of the weave gaps  make  it a smother sand down  even if you ran the veil over the masking tape
  Or use filler

  "go with what you know" didn't apply
   I moved the whole production inside because yesterday was such clammy weather, so i bumped the ambient temp up 15 degrees.
   That was enough to start the kick-off a little early.
   Everything worked out, but i was definitely fumbling to get it all wetted out

   I definitely keep the total volume of the pot down at all times....but one more subtlety from the JL vid is he seems to add both parts to the pot....just doesn't mix it until he's all set....  so it sit's like a Mai Tai floater for a bit....I don't have that much courage...and yeah...quick scoop out of a bucket for the microballoons is laughable compared to my  prep....but i def think that stuff shouldn't be in your lungs and am way more cautious, as i often see it floating around....but every little step is time

Laid down some serious cloth today
Had to laugh.........because although this thread is great, it's all just fun and games until you bump up against  pot was a scramble to keep it all flowing! 

Pics to follow when FrankenFoil is complete   3 more weeks at  2 hours/week  (teenagers rule the roost)

definitely  some glass cloth over... 4oz for me cause i have a roll with a  fine weave.

Mat 2oz i think would just pull apart and be uneven

That CF is thick and rough....the glass lets you work in the poxy without pulling the cf apart, and it gives you an edge taper  for a nice edge. i overlay just a 1/2 "  past  the cf.....Hard to cut the CF cloth that thick and have a nice fine edge....the glass kind of holds it down and smooths it    Again, alot of it comes off

Kick it all off at once=stronger, two distinct layers probably gives a  finer finish

I am not 60 grit certified....i would create much bigger problems....but again i love lifting the tape when late tacky-stiff from outside edge towards the cloth and at that point you can cut the glass right at the tape line with a razor   Timing is everything

I just used 120 to take down a similar edge on some  6ish Carbon

The tape definitely defines a line to come down to   I got lucky and was able to bring the tape up to perpendicular when things were late tacky.... ..maybe 150 if you are just gonna finis there.....

Definitely helps to have some sacrificial 4oz glass on top 

And yeah appreciate JL's vid....I use the new Glad wrap for poor mans vac bag and smaller's nice to pull it smooth

Looks alot nicer than East Coast , and yeah very nice shots.... but that leading edge nose is pushing up water?
I haven't seen that elsewhere, but it' s on both shots....

Can always bend the knees least you are center line

Sux to have to pay to ship a board TO Hawaii.
Superumped on the Supertech....rails are SO fine...

Thanks guys!

 I love the Forum for this kind of learning

Think I'll do at test rail wrap without making a poxy mess, but yeah it might keep bag wrinkles down and be smooth it it works

Add a poorly heated shack, a New England winter and a heat gun....:)

Pono , jrandy or other....

Were you saying that EPS sheets can work well as a breather layer?     I have plenty of 5/16 sheets lying around.   Was using quilting material, butthe eps is tempting as easier to work with maybe

If so, can it wrap rails and angles?.... Obviously when it's dry it just crumbles when flexed, but i guess it can make some bends when pulled down

cowboy ...anytime it can all kick off at once is better...unibody construction  I'm sure builds vary, but next layer on tacky  is good..

BTW, the 3M  77 on skin to divinycell was a fail for me, as i was trying to follow a rocker, and using 1/2 divinycell....had it down tight, but then the sander vibration started lifing it off, and so i went to poxy
It' a reverse or double sandwich, and the hard skin was first...vibrated too much

Clearly it's winter around here!

So on a far more comedic level of board drying....Did anyone ever see the DingKing board spinner on Maui?

The concept was to centrifuge water to a tip...(presumably the crash site tip)

It looked like a giant lawn sprinkler on steroids.....spun a board at maybe 400 RPM, and threatened to kill anyone within it's wobbly radius.

Personally, water ingress, and a few dings brings me closer to Spousal-Permission to get a new board.....She is far less happy about all of the fibers/dust/sanders/microballons/ noise discarded cloves masks and mess.....
