24" X 1" Belt Grinder

[LMMasterMariner]

Made small 24" x 1" belt grinder for my little workshop.

As my workshop is only 3 x 2 meters (6 square meters) and already have lathe, milling/drilling machine, 2 benches, etc inside, there is no much room left for big machines. Actually I don't need 72" x 2" belt grinder at all. This small one is all I need.

Materials used:
mild steel, 304 and 316 st. steel, 6061 aluminum, angle grinder.

Unfortunately cordless grinder died. The only 2 good things about this cordless grinder were: 1. cordless, which is good as you don't need extension cables when moving it out of workshop and 2. several speeds for various materials and various grits belts. All the rest wasn't so good. No enough power for this task to start with, spindle lock button, etc... Lidl brand Parkside came with 3 years warranty, so I returned it to them.

Either drive wheel or tracking wheel must be crowned (barrel shaped), not the contact wheels. As drive wheel is perfectly fabricated and well balanced, I crowned tracking wheel. This is the blue one, which I ordered from aliexpress. They call it chain roller tensioner. I bought 3 of them as they were very cheap and I was too lazy to make them.
Later I just replaced them with ball bearings (62200 - 2RS1, 10 x 30 x 14 mm)

3 drawings attached and the rest can be seen in the video clip.
