Very nice. I use this feature for a cooling spiral on molding tools where the water travels up on one start and down the other to a in and out circuit. the design is dead start and stop.
Is it more difficult to cross thread a multistart thread compared with a single start thread ? If so this would be another reason to use multistart threads on things like bottle caps where the threads have wide tolerances - particularly on things like metal caps on glass bottles.
I'm having a difficult time finding an example. I thought I figured one out but tried it tonight and it was wrong. So I was wondering if you have an example of a line or block of G Code for a 4 start thread.

"...because the lead angle is steeper, less force is required to fully tighten one part onto another..." Shouldn't that be the opposite? smaller angle should require less force to tighten??
It might depend on exactly what he means. Let v = linear velocity of the nut (in/s); F = force of the nut against something it's pushing on (lbs); w = angular speed of the nut (rev/s); T = torque on the nut (in-lbs); and L = lead of the multistart bolt thread (in/rev), i.e., how far the nut advances in one revolution. Then, by definition of L, we have v = Lw. For an ideal bolt-nut system, with no friction, power is conserved. Therefore, Fv = Tw. Therefore, F = Tw/v = T/L. So, maybe you're both right depending on which force you mean. For a constant applied torque, T, as L increases, the contact force between the nut and whatever it's pushing on decreases and the video is right. But, for a constant contact force, F, as L increases, the torque required on the nut, T, (i.e., the force you have to apply to the nut times the radius of the nut) increases and you're right.
Watched video not for solid works but for difference between single start and multiple start thread.Thanks to you concept was cleared.

Great video! Please, could you release this file por 3D printer (STL version)?

Appreciate it man.
Cool
Are different start threads compatible? In other words, can I joint a single thread screw with a 2, 3 or any different than 1 start thread nut?

AWESOME EXPLANATION SIR ......
please release the file for this to be 3d printed please
♥.♥
Cool Share. Cool Thanks.

Yes, he is wrong
