Fabrication and Cost
- Ease and low cost of fabrication is the primary goal, as a high-performance lathe is perhaps the most important tool in a workshop
- Construction consists of a concrete bed
- Cost is that of 4 bags of concrete for the bed, chuck, cross slide, and
- Motor cost is included in LifeTrac infrastructure
- Motor coupler to lathe shaft is machined
- Commercial chck is the main cost
- XY table constitutes a cross slide
- Tool post is fabricated
- 2" shaft constitutes a mounting surface for an xy table and for tail stock
- Feed-through shaft is present, but is only 1 foot deep
- Cheap 2 15/16" bearing
Specifications
- 12" lathe
- 1/1000" accuracy via bearing tolerance and chuck tolerance
- Heavy duty axial thrust acceptable, as determined by 3" shaft and bearings
- Radial thrust determined by set screws on 2 bearings, with 2 extra full split collars
