We received our Misumi slides today. We measured and calculated the lengths we need to have the effective skyscraper arm lift that we want.

Actual length of one extended slide: 16.5”

Effective length of one extended slide when installed: 8.75”.

Effective length of total slides = number of slides times effective extended length plus length of base slide mounted frame:

(5 x 8.75“) + 7.75“ = 43.75” + 7.75“ = 51.5”

So, the total height the arm can reach equals the mounted height plus the length of the arm:

Total height = height of base off floor + arm length.

4.5” + 51.5“ = 56”

At 56” full extension, we can stack the following number of stones (each stone being 5” tall):

56” /  5” = 11 stones

Realistically, probably 9 stones plus a capstone.

See 01-02-2020 for updated calculations based on actual installation.
