Yes, you are correct. The formula assumes that 3 points are used to define the radius, and the 3 points are exactly what you described.

My preference would be to design the top and bottom beam sections eseentially the same as they are both going to see identical forces. Your bottom T sections look like they are going to deflect a lot more than the top I beams. Depending on sizes this may be a moot point. I also like the idea of tyin...

I was wondering if using the force created by the air bladder on both sides (top and bottom) could allow the pressing of 2 skis at a time? The air bladder, sandwiched between the skis, would push one ski upward into the top mould, and the other ski downward into the bottom mould. This would keep the...

There was a posting in another area of the forum that suggested a ratio of 200/250 for the area behind/above the binding. So the percent for the tail would be 200/450 = 44%, which is pretty close to the 42%. hose-man....i sent you a few pm's re surplus fire hose you still may have for sale...can you...

Here is a quick and fairly accurate way to get the radius from the ski dimensions: L = total length of ski in cm TP = tip width in mm W = waist width in mm TL = tail width in mm First we have to make an assumption as to how much of the ski's length is part of the actual radius. I have found that 85%...

I think an enclosed side design would be very efficient to build and could be made entirely out of plywood. If it has few disadvantges in terms of function then I was going to proceed with design and FEA to verify the concept. Also I have an idea for a cost effective way of getting it heated to 170 ...

What disadvantages would a ski press with the sides totally enclosed create? Of course the ends would be open so that the mould could be slid in before the air bladder was pressurized.

Thanks for the 42% number. If you were building a std all mountain ski with sidecut and camber, would you design it so the min width corresponded with the boot centre (assuming the 42% rule) and the max camber was situated at this point as well?

Would it be possible to add the center boot location on one of your CAD drawings, and possibly a side view showing the relationship of the camber to the side cut? This would be a big help. Thanks.

I have read a little bit about how to determine exactly where to mount the bindings, and need some help in making sure I have this correct before finalizing my design. My understanding is that the ball of the foot should be over the midpoint of the chord, and then the middle of the boot is estimated...

Greetings, I was wondering if anyone has establised an ideal temperaturs for curing the skis? My thoughts on the cheapest way to provide the heat varies with the end temperature required. If a temperaturs of say 150 F is good, I think enclosing the press and supplying heat externally using a propane...
