Instructions on Completing Mock-Up of Track Slide Design for Lift/Lower of Center-Mounted Footrests on Power Wheel Chairs

Step 2 Adjusting Track Slide length

The final outcome (1st image) is shown in this step to give you an idea of what you are eventually going to end up with, and also help elucidate some of the reasoning and steps along the way.

The first real step of construction is now upon us. First, the track slide may need to be cut down to size (less than 14 inches between base of footrest and seat bottom) in order to fit most power wheel chairs (Refer to final outcome pic, 1st image for better idea of where the device rests). Do this with a hacksaw.

To cut the track slide, you will need to cut both the track base and the track inset separately.

Terminology (Fig 3, 2nd Image)

track slide will refer to the drawer slide
track base will refer to the non-mobile base portion of the drawer slide
track inset will refer to the mobile inset portion of the drawer slide

After cutting the track base and inset, you may have to recreate the original locking mechanism. Fig 4, 3rd Image. showcases what I did compared to the original locking mechanism. What I did was drill two holes as the stopper for the ball bearings slide, and drill a hole and use a bolt as the new catch. This only works because the excess metal from the drill hole protrudes and acts like the original stopper bolts/protrusions.
