Sometimes building small items requires small tools. This pocket lathe is 8 inches wide, 3 inches deep and 4.5 inches tall. Yes it does fit completely in my jacket pocket and cargo pants pocket.Please note that there are some ideas for improvement posted at the end of this Instructable.
This started as a desire to make a miniature chess set
Step 1: Order parts
I disassembled an inkjet printer to get the motor that drives the print head. This motor has enough power for turning pine and other light woods. It is too weak for working with aluminum or copper.
The bearings and support blocks are from vxb.com
The gears are from sdp-si.com
I used some scrap pieces of ¼ inch hard board to make a base stand.
You will need 2 of the ¾ inch shaft supports part number WH12A
You will need 2 skateboard wheel bearings 608ZZ type
You will need drive gears or belt system. This is completely dependent upon your motor selection.
I used nylon bevel gears for a reduction in the motor speed 1:2 (24/48).
Step 2: Assemble the rotating parts
Begin by enlarging the opening in the shaft supports. These started out at ¾ inch and needed to be 7/8 inch. I used standard drill bits to accomplish this. You only need to enlarge the hole about half way through the thickness of the support.
At this time you install the bearings and tighten the support.
The bearings go towards the inside of the working area.
