I spent a couple of hours in the shop this morning, and built some bases for my Sherline tools.
Over lunch at Big Fat Burrito recently, my friend Ryan Mendell recommended that I top my bases with a layer of Ultra High Molecular Weight plastic (UHMW). He reasoned that oils and swarf would clean up nicely – and since he is the most talented machinist I know, I followed his advice. On Thursday, I made a trip to Plastic World, a local supplier where I buy styrene sheet, and had them cut me two pieces of 1/8″ thick UMHW to the base sizes recommended by Sherline.
On the way home, I hit a local building supply company for a sheet of 3/4″ MDF, some wood, and a selection of hardware, including rubber feet. (Sherline recommends the rubber feet to dampen vibration … and they do!)
I used the UMHW and the dimensional lumber to lay out the base sizes then cut them with my track saw. Glue and screws secured the wood rails to the MDF. I used dimensional number of various “1 by” sizes – being careful to choose sizes that were as high as possible to help contain the mess, while still low enough that they would not interfere with tool components such as hand wheels. I also ran strips of 1×2″ underneath the MDF base to raise it slightly off the table, and mounted the feet to these. This gives me enough air space under the machines to easily slip my fingers underneath to lift them by the bases.
The UMHW is held in place by the bolts that hold down the machine tools, so that I can remove and replace it if need be. I used the tools themselves to lay out and mark the locations of the bolt holes. Machines are secured with washers, lock washers, and nuts from below.
(Thanks for the advice, Ryan – I’m really pleased!)
