A good range is 45-55. If I press higher than that, I usually end up with texture of the glass showing through the topsheet. 45-50 is just about right for a perfectly flat top, adequate squeeze out, and properly bonded layers.
As Twizz said, leave under pressure until fully cured.
Have Fun!

I have done this layup and had the same issues described above. What works for me is using a composite veneer (bamboo is a common one). If your veneer is wavy, it will lift the top sheet prior to pressing exposing air between the clear and veneer regardless of what you try. You'd think the press wou...

I have the same machine. Paid $1000 last year and it is in great condition. When I was looking around for these machines, they seem to consistently run around 1K. MM is correct in that SVST will have all replacement parts. Make sure the coolant pump is working and all bearings are good. People forge...

If you are thinking about 2-4 threads of CF both top and bottom, why not just use a 1 inch strip of the CF either above or below? This would be a lot faster and easier than separating individual strands. Also, a 1 or 2 inch strip of CF in a set of skis adds a lot of life to the flex. Were you thinki...

Actually, too much pressure can squeeze out too much epoxy and make the laminate weaker. I press at 50-55 and everything comes out well bonded and flat. I tried going up to 65 in the past and when I did a hard hand flex I could hear a little too much cracking. I think your fiberglass seperation coul...

It's not leaving a low spot between where the extra layer of CF starts and the edge? I was having an issue awhile back where I was rabbiting too far in and the base was sucking up in the void between the core and the edge tangs.. It left a few small pockets that took too many passes on the grinder t...

Twizz! Lookin good! Just bend the brakes with vise and a pipe. You can heat them up if you need. If the plastic melts, that's great. I've been replacing the plastic tabs on my brakes with bullet casings. Fill them with JB Weld and push them into place. I've never had so many comments after people se...
