  1. A desk rising column uses the same mechanism but could not find a secondhand unit, so opted for scrapped wheel chair parts.

    you might need access to metal turning lathe to make the base for bottom af the top column, however you could getaway with a mount head adaptor plate turned upside down with three sturdy bolts to fix it to the top of the rising column.

  2. I have for the last month been engaged in designing and building an electrically adjustable height mobile pier.

    1st attempt was a failure this was made of a 4" inner aluminium round tube and a 5" outer aluminium round tube, two of Arthurs cheap run guide rings and two satellite dish acuator jacks three pier stand legs.

    however this was unsteady at height extented to 36".

    Latest project was to build a Pier with a center section made from an electric wheel chair seat rising column.

    attached the EQ-4 mount to the top with a 6" section of 4" aluminium round tube. to stabilise when raised and to take weight of telescope to prevent sway constructed duck feet.

    see attached photos.

    initial test apear to work giving an variable heights of 24" to base of mount to fully extended 36" to base of mount.

    as can be seen in the pictures, reducing back and knee bending to a minimum.

    Column section taken from a Infracare twister wheel chair that had been scrapped, requires 24 volt 2amp

    well pleased withit but might redesign the duck feet.

    comments and critics welcome I've got thick skin, (or so the wife say's)
