Step 4: Phase 1.1 Basic Set-up:
Frame A, shows an image of a finished side supports. To create these pieces, cut the horizontal member to the same size as the bridge piece, in my case 13 inches. In order to determine the length of the vertical pieces place the upper roller assembly on the keg and level it. Next take a measurement from the bottom of the runner to the mounting surface of the lathe. Once you determine the distance remove 1/8 of an inch. This gap will provide a method of tensioning the keg to the rollers and will help in the controlling the cutting path of the lathe.
In this frame size counts, if you happen to have long enough screws ignore this step. For us the less fortunate, drill some hole about 3/4 of the way through the horizontal pieces. These holes will be used later to mount the supports to the table.
Once the pieces have been cut and assembled, soft fit all the pieces around the keg. The upper roller assembly should have a little slop and the legs should be square along the side of the keg but not touching. When you have finished making the adjustments, secure the side supports by drive four screws through the lower side supports into the table.
To mount the upper roller assembly, drill a hole on each end of the cross members, these holes should allow the mounting screws to fall through. Make sure that the holes line up with the vertical leg supports as you will be securing the assembly to it. The final step will be to secure the assembly to the support legs. As you are screwing the assembly down check and see if the keg spins freely. You will want to apply enough pressure to spin the keg, while restricting the up, down, and side to side motion. In my experience the tighter the better, but this will make you work harder. Remember if you need more adjustment you can always cut off a little more off the side supports.
