Design Requirements
Design Requirements
The track will be approximately 18 inches long and the legs will be about 10 inches long, though this is subject to change based on the size of the motor we purchase.
The base will be made out of metal and the head and tail stock will be made out of wood.
Our lathe will require a horsepower of ½ to 1 hp, depending on the speed the lathe will run. We determined this through online forums as well as torque calculation equations based on the force exerted by the gouge and the diameter of the stock.
Design Specifications
Design Specifications
The lathe will be spindle turning only, and the stock to be turned will not exceed 1x1x6” so as to keep the torque low and the size reasonable.
We simplified the design of our tailstock to only be a permanent live center rather than having it be interchangeable. There will be 3 different speed settings, each with a combination of pulleys that keep the belt length consistent.
The belt tensioner should be attached to the motor side rather than the track-mounted side.
Safety Requirements
Safety Requirements
The motor will be placed under the track partially to act as a weight to stabilize the lathe and partially for simplicity’s sake to keep the lathe symmetric and compact.
There will be a thin soda plastic housing around the pulley on the head stock end of the lathe so people can't place their fingers anywhere near the moving belt.
Budget and BOM
Budget and BOM
The budget for this project is $250 which is quite small. We had to scavenge some of our materials to create this under such a small budget. Below we have a Bill of Materials generated in Solidworks. For a breakdown of what we bought with the class budget and what we scavenged see this google sheets.*
