DIY belt-driven backpack-sized IGUS slider

This project started as an DryLin W1040-A Linear Motion System purchased from Amazon.com. This is the smallest slider IGUS currently makes. The goal was to create a backpack-sized lightweight slider similar to the Kessler Pocketdolly, but much smaller and lighter.

DIY belt-driven backpack-sized IGUS slider

This project started as an DryLin W1040-A Linear Motion System purchased from Amazon.com. This is the smallest slider IGUS currently makes. The goal was to create a backpack-sized lightweight slider similar to the Kessler Pocketdolly, but much smaller and lighter.

I cut the slider down to 30″ and drilled and tapped 1/4-20″ holes for legs and the Arca Swiss style quick release plate. I used an extra long quick release plate and drilled 2 holes to keep the slider from twisting when mounted on the tripod. The legs are made from dual flash bracketsand some round knobs I found on eBay. The knobs were plastic and had to be dipped in rubber Plasti Dip to keep the slider from sliding around on a smooth surface.

A 1/4″ hole was drilled in the carriage for the Arca Swissstyle ball head. 10-24 holes were drilled and tapped on each side of the carriage to hold small screws around which I was going to wrap the drive belt.

The drivetrain is built around a Sherline 2.5″ handwheel – this is the only handwheel I could find to fit a 1/4″ shaft. The 1/4″ shafts, 1/4″ .08″ pitch timing belt and timing pulleys came from McMaster Carr. A .79″ OD pulley was selected to have the belt fit comfortably between the IGUS gliders. The top of the shaft is held by a bearing block I found on eBay. The bearing is elevated by 1/4″ spacers and attached by #10-24 screws.
