I have another method of applying metal edges that won't require tons of spring clamps. I built a prototype and did a quick demo of it and it seems to work well.

I got the idea from a wood working technique of how to glue up 2 boards with only a few clamps. Basically you shave the middle of the edge of each board, then apply the glue. When you clamp the middle of the boards it pulls the middle in and applies pressure along edge of the boards, requiring a lot fewer clamps.

So, I took a scrap piece of MDF and glued some scrap metal edges to it. This became my edge guide. I routered a sample piece of ptex in the usual way using a template.

Then using my edge guide I placed it against the template/ptex. There will be a tiny gap the width of the metal edge between the edge guide and template. Next I inserted a piece of metal edge in that gap and pressed down. Then I took a pistol grip clamp and applied pressure. Since the template is shaped, the clamp pulls in the edge guide applying pressure along template/ptex.

One pistol grip clamp applying good pressure for over 12 inches in each direction. Just be sure the metal edge is flat.

Here's some pics of the prototyping. This pic is the edge guide and shows pieces of metal edges glued to a piece of MDF that act as spacers.

Here I have the edge guide clamped to the template/ptex with the metal edge inserted in place and applied super glue.

Here is the metal edge on the ptex. As you can see I glued to the wrong side of the ptex. BUT the metal edge has a great fit.

For the tip and tail sections you'll still need to use spring clamps as before. So perhaps a dozen springs clamps and 3-4 pistol grip clamps will be all you need to apply edges.

I'll use this method on the next pair of skis I make. The edge guide should be about as long as the running length of the ski.
