I've a short bar of teflon and made a 15mm wide lead nut for a M12 steel rod (standard thread) to build a silent linear actuator mechanism.
The nut raises a platform with a load of up to 250N.
Have limited material to experiment, so don't want to proceed entirely by trial and error.
Can...
I've been happily working on a platform design as above (500mm long, 350mm wide, vertical angle-irons 450mm long; cylinder represents linear actuator). The purpose is to provide 300mm of vertical motion and carry a load up to 20kg (that could even be placed at the far end).
The rollers are...
A 20mm steel rod is held vertically by a dry plastic cylindrical bearing such that it can rotate freely in the horizontal plane.
An aluminium bar with a 20mm hole in it is slipped onto the rod and, supported by the bearing below, can rotate freely in the horizontal plane.
The bar must support...
Hello.
I'm new to this forum and come with a question.
There is a welded steel frame structure to the top of which is attached a three wooden sheets (not touching) adjusted to lie in a single plane. The frame has 4 "feet" that can be adjusted to ensure that the plane is horizontal.
There is...
