@Roo2 , Your slot idea is interesting. If you used a lifting keel you might be able to have the trunk for the lifting keel also be the slot for...
@philSweet , You're right, of course, but it's worth looking at a cat rig with the assumption that some kind of built-in mast raising system will...
As a committed trailer-yachter, I like your concept. Water ballast greatly increases the range of vehicles the boat can be towed with, making a...
I dinged my propeller a bit and I'm trying to assess the damage. I've measure the axial runout but, unfortunately, I didn't measure the runout on...
Compressed air isn't such a good idea because it stores energy in compression. Your part could fly across the shop! Water is much better.
I've used this method to develop an empirical drag v. speed function for a car. It takes a fair number of data points to get a good result. If you...
Not specifically wax-related but, if your concern is getting the part out of a deep female mold, I've seen a clever method used on racing car...
I've noticed that mentioned in various books. Is that done merely because it isn't worth the extra effort of estimating displacement for...
Nor did I expect there would be. That's why I originally asked about guidelines, not universal answers. Let me give you an example of the kind of...
No doubt. But I'll waste a lot less time with trial and error if I make some attempt to understand what I'm doing before I start building.
From the above comments it appears that nobody here is aware of any quantification of the amount of twist that a developable surface can sustain,...
By warp do you mean twist and curve simultaneously?
I've been looking at lines drawings for stitch-and-glue kayaks. Some of the lines drawings (if accurate) depict surfaces that have twist, as...
