Electric drill vise mount

Electric drill vise mount

[Update 4-19-21 Doing some things in mid-air is unnecessarily difficult. I made a little table for support. The "Table" file replaces the "Ring" file. It extends out under the drill chuck, so a tool has something to rest on when turning an object....]

This cradle snugly fits the $18 ($9.99 on sale) Harbor Freight 3/8" variable speed, reversible, keyless chuck, 3,000 rpm, 3.2 amp (400 watt) drill.
SKU numbers are 60614, 3670, 61719, 62856 and perhaps others through the years.

Works OK for light-duty sanding, grinding, wire brushing small parts. I used 3/8" x 1" bolts. Finger-tight is adequate.

The trigger has no speed-dial, but it has a universal motor. So I lock it at full speed, and use a $5 (600W) light dimmer for speed control.
