I am preparing the jigs I will need to have a go at segmented turning, and have made up a disk sander to sand the segments. This was based on the design that Skew put up, but with the addition of good dust extraction, and is fitted to my Jet mini lathe.
The pics are all after the fact, so there there isn't a step by step like Skew's. But there should be enough to give the general idea. The dust extraction works perfectly, with zero dust escaping (as far as I can tell).
pic1. Made up the box, and a strip of ply that is a snug fit into the gap in the lathe bed. Sat the box on the lathe with it's front face aligned to the sander disk, then slid the ply strip up from the bottom, using some spots of ca to hold it in place. The assembly was then removed, and the locator was screwed on. At the top of the front face, is a slot for the vacuum that sucks dirctly from the sanding disk. The vacuum hose attachment, is a modified vacuum cleaner tool, which is screwed onto the side of the box. The cut-out through the side of the box, is about 6mm smaller (L x W) than the vacuum tool.
pic2. Set up on the lathe, and clamped down. Clearance to the sanding disk is about 1 mm. 2nd vacuum slot is on the top face, near to the sanding disk.
pic3. The clamp down arrangement is simply a threaded rod inserted through the bottom, and locked in place by nuts. Then I have a U shaped clamp, that clamps against the bottom of the lathe bed via a nylon tri-nut (Bunnings).
pic4. The source of the vacuum is, of course, a vacuum cleaner, which I have hanging above the lathe out of the way This is one of the 'cyclonic' 1800 wt units, which I bought new off ebay for a good price (I think). It's got a variable speed on it, and I've found that it only needs to run at lowest speed to do the job. At this setting it's quite quiet, and wont upset the neighbours. The dust container is ridiculously small, and I dont see how you could vac a house with it. But it's certainly sufficient for what it's now doing. Later on, I am going to make a mini mini-cyclone, and then I'll hook up it up to the lathe.....but that's another project.
.......continued next post.
