A Steady Rest is useful for supporting long parts in the lathe by stabilizing the part. The bearings provide low friction support (making it ‘live’-support?). This 3D-printed part is not intended for heavy duty and cannot withstand direct cutting operations typical for a lathe. It can support the tail end of a long part, preventing it from bending or vibration.
The maximum supported diameter is about 20mm with the 4x10x3 bearings. The original used 4x9x4 bearings.
The Steady Rest can be mounted with two screws to attach it to the bed.
Note this is an experimental part, not properly tested with heavy loads. It is expected to work with low to medium loads when printed with enough perimeters and a higher infill.
The printing material used is ASA, with 6 perimeters and 30-40% infill. More perimeters works better to enforce the outside than higher infill. Other materials like PC (Poly Carbonate) or PA (Nylon) will also work. PETG is probably too flexible and PLA will bend under pressure.
The extra materials used are:
- M3 flat-head screw 10 mm, 6x
- M3 hex-head screw 18 mm, 3x
- M3 nut, 9x
- M6 hex-head screw 40mm, 2x
- M6 nut 2x
- Bearing 4x10x3 (684ZZ), 3x
The design is experimental and not yet properly tested. Beware!
