Secret to nippers is keeping them perpendicular to the edge.
Properly built 3 roll edge bender should keep them true.

It was all 3 of us could do to get mine on to a low trailer last time I moved mine!

Is it 3 phase?

Nice deal!!!

Gotta get my floor coated in the shop before I move all the crap in there. Epoxy? Best thing I ever did in my shop. Leaning towards Rust Bullet, it's a single component moisture cured urethane. Way less prep and just paint it on. How did the epoxy deal with the fire? Sorry to hijack your thread Chr...

I bought some vector net last year from Foam-EZ but haven't had a chance to try it yet. It was pricey and shipping doubled it. Bought the 1/2". http://www.foamez.com/vector-net-xp-227-12-diamond-pattern-33-wide-per-foot-p-959.html It's not CF, it's Techora aramid, but it looks pretty cool. Plan was ...

I would shorten up the running length and make the tip longer.
Around 120mm?

Would make it look more proportional.
And give a bit more tip height.

Other than that should work.

I've posted this before but will humor you and post it again 'cause it's been a while. The best thing I've ever found beside leaving your wood sidewalls untreated, is boiled linseed oil. Wipe it on, let it dry, wipe it off, and you're done for a year or more. I've got skis with over 120 days/6yrs st...

Vacuum should easily bend your wood cores.
Unless you prebend your cores they will not lay flat in your mold and make your layup and alignment more difficult.
They will also add some internal stress, trying to straighten out inside your ski.
This is one reason why people use tip spacer.

heke, Although I use a pump similar to that one, I would look for an oil-less pump for ski building. Even if you can't see the oil mist coming from the exhaust it's there. And if you're using it inside the shop it will slowly contaminate anything that is in there. I run my pump outside with a long h...

Are you using heat? Heat will make your epoxy thinner and it will run away/squeeze out. My epoxy is very thin, and has to cure at room temp then get post cure heat or it will run out of the ski. I only heat to 120-140f and my epoxy will run right out of the ski and all over the press! Try your exper...

Clear pine works nice, just hard to find. Most pine is quite knotty. Fir usually has pitch pockets which can cause some grief. Spruce is nice but most here has quite a few big (but tight)knots Aspen and poplar are quite similar. A few small knots won't really hurt. I've used larch with loose knots a...

What I also lean today is that if there is +23C inside and you take glued edges and bottoms from inside to outside -28C and to garage. Even in 30 seconds in -28C bends parts so much that there is new gluing work waiting. It was incredible fast reaction. Bottom was bended about 50 cm..like banana. H...

I have seen here some pictures where the tip/ tai of the bottom with edge is bended to mould before laminating. Someone has just roll with pipe. I was thinking to use same method as I don't know how much my vacuum pump can press. I think that pre bending would also give better result. There is a pr...
