Last week, in machining up a whole lot of bog oak, I suffered an absolute workshop catastrophy:
Now, the thing is, I've got a perfectly good extractor mounted in the corner of my workshop, wired up, and working:
I'm sure I must have posted about it previously. I got it from DaveL, when he upgraded to a bigger one, and I had mounted it on a custom made plenum and chimney-thing. Years ago. Goodness, maybe 3 or 4 years ago. I've no idea really. It has just sat there occupying space ever since, because I had never bothered plumbing in any ducting. Well, two full days cleaning up the workshop after the bog oak catastrophe quickly convinced me that it was time to get some extraction sorted. When I say cleaning.......I took every piece of wood out of my off cut store, and brushed and hoovered them individually. I took a bucket and sponge to my bench. The place was a disaster.
I only use 2 machines (well, if you don't count the lathe). The bandsaw and the planer/ thicknesser needed connecting to the extractor. How difficult could that be? Here they are:
Note the plenum of the extractor in the top right hand corner above my pillar drill.
I bought some ducting and some joints, and made a plan:
I decided to have a pair of blast gates on the side of the plenum, and have separate pipes go off to the bandsaw, and to the P/T. I made a fairly simple pair of blast gates mainly out of 1/2" ply:
That last photo gives the impression I glued it together, but this was just a test to see if it moved freely enough. I had to sand a bit of thickness out of the gates. They are to be screwed together only, so that if anything goes wrong I can take it all apart and repair it. I cut a hole in the plenum:
......and screwed the blast gates into place:
I had forgotten to buy the fitting for attaching ducting to a bulkhead, so I snipped the ends of the first pipe, applied some heat, and did a little bending:
I made a couple of retaining rings out of ply:
I failed to take a photo of the support frame I made from roofing batten, to hold the other end of the pipe, but here is the pipe as it meets the plenum:
I had ordered only 45 degree joins to avoid dramatic changes of direction, so working out the length of the various pieces was a bit tricky. Here it is propped for the night to allow the Hippo 3 adhesive on the joints to set:
The following day I did the flexi:
It was a complete pain to get the Jubilee clips to sit properly, but that aside, all went well. That was the bandsaw done. On to the PT.......
