Title: Amount of Glue for Plank?
Post by: DN 5449 on May 24, 2011, 09:20:38 AM
What is the average amount of glue that building a Plank takes.I seem to be using up a lage amount.So far with just edge gluing the skins and core I have used up
1 tube of six-10
1/2 quart of West 105 Resin
3/4 of the small can of West 207 hardener.
Not sure I will have enough to finish Lamenating all the layers together :-\

1/2 quart of 105!!!

I would have recommended starting with 1 gal of 105, plus hardener - 205 is my favorite because I don't like to wait.

Plus, there is no reason to edge glue the skins unless you plan on using a hollow core.  If you do plan on using a hollow core, my advice is to revise your plans...

Solid Core Paul

1 quart of 105 is suppose to cover 100 square feet of a pourous surface.My calculations tell me a plank even with edge gluing is a lot less area then that.

A quart of 105 should be adequate.  Using 205 or 206 (slower) hardener is very much more economical than using 207.  207 is good for finish coating, but too expensive to use for lamnating.   If temperature is very high, then use 209.

With shop temperature in the lower 60 degrees F., 205 should give you adequate working time. If warmer, use 206.   Mix a couple of squirts at a time, put in roller pan, and roll onto surface of boards, The West System foam roller covers are great.  Just remember to tap the roller covers off the frame before the epoxy sets up.   May have to roll a little extra epoxy onto the cedar core if the expoxy soaks in.  The epoxy will not soak into the ash. 

Stack up the boards on the jig and clamp, making sure no twist in the jig.  Check with level as clamps are tightened.   Leave in clamps for at least 36 hours. 

Check deflection after unclamped and hope for the best.

With something like fifteen to twenty planks built, I've gotten it down to a consistent 8 pumps for the wet out, 10 pumps for the thickened fill mixture (plus a one of two more if going with more strips than my 4-4-3 construction).

I second the solid core mention from Paul...I learned a lot from him! I wouldn't build hollow unless I wanted to consider the planks to be "consumable supplies."  ;)
