I was messing around with the idea of using some super 77 to tack up the rails so i could smooth out the glass before I shoot the epoxy. Am I just asking for trouble here? I did experiment on a box that seemed to work out fine. ( I glassed over my brothers wrapped Christmas present! It was pretty fun watching him figure out how to open it!)
Any advise would be great.
BTW this is my 4th board. 7’3" x 21" x 3" swallow tail. The first 3 came out great, 1 poly, 2 RR epoxy. All free lapped.
Thanks in advance,
Aaron
PS
I tried to search, but could not find much on this…
All I can think is that you might run into problems if you glue up the rails only and then find out you didn’t tighten it up enough before glassing, and end up with wrinkles when you squeegee it flat. That and not knowing how epoxy would bond to the glue.
I’m gonna have to borrow that glassing presents trick…
on a similar note, I was thinking about sticking some pins through the glass into the blank near the stringer before lamming on my next (2nd) board cos the first board i did the glass slipped a bit as i was squeegeeing, would this work ok? I was thinking you could pull the pins out as soon as you finished each side and then any pin pricks would get filled with the hotcoat.
You’d probably risk tearing or stretching the glass if it did slip when the pins were in. I lay the glass where I want it, then pour resin down the stringer to start and let it sit for a few seconds, then start to lightly spread it out with the squeegee, and slowly add more and more pressure, it shouldn’t slip if you just take your time before you really drag it tight.
No reason to stick it down with glue, more trouble than it's worth and your glass is liable to fold up because it can't stretch as you squeegee excess resin out.
Pour your resin down the stringer, spread it lightly at first end to end towards the rails, then tighten it up as you squeeze the resin out.
Somewhere out there is a glassing video done by one of the members here that goes by bammbamm. Follow that technique and you can't go wrong. You could also buy JC's "Glassing 101" or Greg Loehr's version, I think it's called "Epoxy 101." Better yet, go to a glass shop and watch a good glasser do a few boards.
I should have been more specific in my earlier post. I did not mean the entire lam, just rail reinforcement. I plan to armor the nose and tail edges a bit with 1 or 2 additional layers od glass.

Good stuff Guys! Thanks!

In that case, glass as usual. After the resin has set a bit, lay your cloth on it where you want it. It will stick to the resin, then apply your epoxy. I do this when I want to reinforce the nose and tail areas.
I used some super77 to tack 1.5oz glass to a venner prior to putting it in a vac bag. Since the glass was so light I had a difficul time getting it to lay down without wrinkles and its a nightmare trying to get them out. In hindsight it seems unnecessary but if you want to give it a go make sure you have someone helping you.
EDIT- I just re-read the thread an noticed you only want to do it for rail reinforcement. In that case I say its a very good idea. I tried to laminate some rails just using bits of tape along the top edge to hold the glass strips to the board and it was a real mess. The small bits of tape pulled off the board under the weight of the resin, the ends fell on the floor, somehow I got resin in my hair… Never again will I do a rail like that. Tacking it up with Super77 sounds like a good solution.
