3D model description

This is a leg spreader to work on the large facial spread useful for martial arts.

This kind of torture device already exists in the market but I wanted to make one at a lower cost with wooden boards, steel threaded rod,... that I had in stock.

I only had to buy a piece of steel tube 40 x 27 x thickness 1.5 mm.

Its yield is much lower than that of commercial products because it is very limited in terms of the effort required to pull it apart.

When the crank handle is overloaded, the friction is such that some parts must be made with a lot of material (wall and bottom thicknesses + large filling)...

After testing, it was the arm axes that I had to reinforce.

The attached attachments are to be completed with those of another of my creations called angle gearboxes.
