Hi everyone
Finished my vacuum system today, here's a quick run through with some pics. The vacuum pump is a new unit from ebay $220.00 delivered. Some old mower parts make up the frame, the rest looks a little complicated but isn't really. A remote oil filter acts as a dust filter to protect the vacuum pump. The vacuum control plate at the top has a gate valve on one side for quick vacuum release with an adjustable bleed valve on the other side, as well as a vacuum gauge to monitor operation of the system. The other fuel filter is used to stop dust entering the gate and bleed valve. The pump on/off switch is positioned up high for easy access. At the outboard end of the lathe, vacuum travels through a home made sealed bearing coupling to allow rotation, four home vacuum chucks complete the system, each made from a threaded alloy base with a glued up six ply face plate in varying diameters. Rubber/foam floating washer is used to seal between chuck and work. All seems to seal up well and pulls maximum vacuum, but will experiment with other materials. With the exception of the vacuum pump all parts used I either had, made or acquired at little or no cost.
