Hi,
I am looking at making a shelf from Yew that has a waney edge - well, it has a few, it’s been cut from close to the bark!
Anyway, I wan to make it flat so purchased some resin from here but as the wood isn’t flat, no amount of clamping has got it right. I used tape to try and seal the bottom but that didn’t work. I have now clamped it as tight to the melamine board as I can and I have used wax to fill the gaps.
I see on the tutorial that they pour their resin in 2, allowing 12 hrs between. I only need 30mm max, would I get away with that in 1 pour or should I still do it in 2, and if it is shallower, would my cure time be less?
I shall see if I can add a pic.....

Nope- apparently is I can’t! 😆

2 coats/ pours is for: 1. seal the edges so if you have a leak it's not that disastrous as pouring a big amount in 1 go and losing most of your resin and second to seal your part so if moist is trapped you wont have to much bubbles. 
2. the thicker the pour, the bigger the volume of resin; the faster it will cure Smile
