Homemade Lathe Sanding Belt Holder

[LMMasterMariner]

Took me some time to decide to fabricate it, even construction is very simple and it's quite cheap to make. Spent less than 30 dollars to make it.

Materials used:

mild steel, thickness 10 and 12 mm
316 st. steel, dia 28 mm / rollers
4140 alloy steel, dia 20 mm / main shaft
2 x 6201 zz bearings
4 x 608 zz bearings
2 expansion springs, wire dia 2 mm, length 65 mm
aluminum 6061, dia 60 mm / drum
various bolts and nuts

Few years ago I saw these holders on the web, but those were outrageously expensive. Still expensive even there is no obvious reason for it.
