Re: m5 inserts for split clips

But you still need a 17 or 19mm drill (dont remember). On the US inserts its just a small hole (9 or 11mm!?). Would need to measure, just out of my memory

Re: m5 inserts for split clips

No, head / flange too big and nothing to prevent twisting. Draw your hook spacing on a piece of paper and then add the flange circles. You will understand ;)

Maybe the js piece works, but it would not be my first choice ;)

Re: m5 inserts for split clips

They are open on both sides so not good. You could close the lower side (where the flange is) but then you loose a bit of adhesion to the base side layers. And if your screw is too long.... ;) The flange is way to big too One us shop is selling this style of inserts with a closed flange. Dont rememb...

Re: m5 inserts for split clips

The ones from skibaumarkt are too big. You need to drill huge holes which are ok vor bindings but in the thin tip/tail area its imho just too big (also because of the narrow spacing needed for clips). Outside dimensions are the same like the M6 inserts

Re: core hardwood inserts

With inserts i dont see a pullout problem in soft wood. But insert sink may be possible. I think you will be fine when you put one more patch of fibreglas between inserts and core. I would not try to fiddle some patches of hardwood in.

Re: Festool HEPA Cleanup

Change your thinking. You produce too much waste for a shop vac. Except you want to empty it all the time. Get a cyclone dust extractor. On this you can connect a standard shop vac, a hepa one or even better some big vac (can be only the motor) staying outside of your room. On my system i fill a 100...

Re: Camber Issues

Check the deflection of your lower I beams if the molds are good (check it with the molds and skis inside as well)

Re: split before or after base grind

Just one thing. If the guy on the grinder is grinding one side like crazy and the other side not, well then there can be a difference. But then you need another skiman or your base is not flat ;) And we are still talking about 1/10th(s) of a mm.

Re: split before or after base grind

Well, the edges are the "fence" for grinding. If you base(s) are flat they halves will be the same, cutout before and grinded after.
