Maintenance day

Cold wet Sunday so time to tackle a few bits and pieces in the shed that have been hanging about a while. Like mounting two magnetic strips on the inside of the door because I’ve run out of wall space for things, and epoxying some handles I turned onto the saw files.

Larger tasks though involved a cardboard box that’s been eating bench space for the last few weeks. The little bandsaw that’s earned its spot in the shed over the last year or two came with a “fence”. Said “fence” followed the adage of doing one thing and doing it well, but unfortunately that one thing was weighing down a bin bag. It definitely was too cool to be square, daddy-o. But there are after-market fences (meaning we couldn’t make it well for the money, so give us more money and we can do it right). Peter Millard did a video on fitting one to his Titan bandsaw a while ago:

So I bought one… six months ago… so it’s aged enough to do something with it now. I’d made some spacers already.

They’re cut to odd sizes because I need to epoxy them under the table so that the fence’s rail has something flat across the base to be clamped to, and the underside of this table is very irregular.

Some five-minute epoxy and a few clamps and it’s time for a cup of coffee.

And I’m stealing Peter’s trick of leaving the mixing stick to be glued to the mixing board so I can check on the epoxy bond without testing the real bonds.

A half-hour of coffee and searching for various bits in the house unsuccessfully (I know I bought an LED floodlight for use in the shed only four years ago, it has to be here somewhere) later, I marked out the depth of the bit of the fence you’re to drill through on the table and then drilled three holes for mounting bolts, two in the right place and one spare in case I need another hole later on.

Deburred them as well obviously. I had originally intended to use M5 bolts, but it turns out I don’t have any M5 countersink-head bolts, but I do have M6 ones which is why my spare hole is a bit small.

Then I stuck the measuring tape sticker into the track where I’m sure it’ll last for at least four days, and bolted the rail to the table. I need M6 wing nuts for this really because you have to take the rail off to change the bandsaw blade (and I also need an M6 wingbolt for the table stabilising screw that normally goes in where the slot in the table meets the edge of the table). I’ve ordered some from ebay so they should get here in a month, and until then I’ll make do with normal nuts and not changing the bandsaw blade.

And now that that’s done, have to square the fence to the table using the adjustment screws under those four holes in the top of the fence.

Or not. I didn’t believe it either so I triple-checked it with two squares, but yup, that fence is square to the edge of the table according to my most accurate Starrett square. I’m not sure what sort of necromancy was used to achieve this, but I’m sure it involved at least one plague of locusts.

And that’s off my bench at last. I look forward to using it once or even twice a year if I’m feeling frisky.

Next up, the chuck I bought for the lathe was a cheap one even normally but I bought a shop demo one that was on sale. And it’s been grand, but it does bind every five or six turns of the key, so I thought I’d take it to pieces and check it and see if it was something simple that I could fix.

Turns out that a lot of the parts were not very well deburred, so I got out some 1200 grit wet-n-dry paper and deburred them as best I could.

There wasn’t a single burr-free edge on some of those parts. As to the pins that held the pinion gears in (the bits you put the key into), they looked like someone had attacked them with a dull beaver.

That’s the after photo. There wasn’t much I could do with that much damage so I chucked them into the drill and ran it at high speed while holding the wet-n-dry paper against it to smooth off the worst of it.

Then blowing out all the dust and grit with compressed air, degreasing with the really nasty stuff (remember the song kids – “acetone, it stays in your liver”) and liberal amounts of PTFE lubricant on the moving parts, And reassembly.

Didn’t think I’d get it back together, did you?

BTW, I haven’t put the regular jaws back on because I want to try the new ones I got. Thing about this chuck is that when you buy it you can either buy it with just the one set of regular jaws or you can buy the entire set of six different jaws, but since I got a demo model, I couldn’t get the entire set. And they will sell individual jaws (or a pack of jaws) for this make and model of chuck, but they don’t sell the flat bowl reversing jaws for it separately so I was looking to find compatible jaws from somewhere else.

So, quick PSA, if you bought the 3″ Xact chuck from Rutlands, and want spare jaws, the Viper2 jaws will fit it. I got these from here, but there are many other places where you can find Viper2 chuck jaws, the Viper2 being a reasonably popular model.

I’ll be trying these out on another miniature bowl in a while I think. They’re really for larger than that, but I want to try them on a 3″ blank rather than finding out they don’t hold well when there’s an 8″ blank in them…

Planting mushrooms

So the mushrooms turned from that branch from Fernhill were finished off; I cut the tenons off the two I turned in the chuck, drilled a mortice and glued in a piece of dowel:

And then Claire, Calum, Sonic and myself wandered up to Fernhill to plant them.

…and then I looted more wood.

Slightly larger this, but less circular. Not sure what I’ll make from it. More mushrooms I think, and maybe I can do a little birdbath…

First bowl!

So the woodturning course I was taking was cancelled because of Covid19 before we got to the bowl turning part of the course. But I had a large variety sack of bowl blanks arrive from homeofwood.co.uk at the start of lockdown, and I’ve been wanting to try bowl turning for a while, so I read about a dozen books on bowlturning (like The Practical Woodturner and others), bingewatched about thirty hours of youtube intruction from a dozen different turners, set the pucker factor to maximum and picked out the smallest minature blank I had…

That’s a three-inch blank on a three-inch faceplate 😀 But we can still do more overkill…

Tailstock support on a three inch blank 😀 Well, first bowl, might as well do belt and braces. So I turned the tenon (and it didn’t look too bad I thought), then I took off the faceplate, chucked the blank up, realised I’d skipped a step, put the faceplate back on and turned the outside of the bowl.

I didn’t have any plan for the shape by the way, that was just something that felt right as I was doing it. Then I took off the faceplate and chucked it up and immediately found that the chuck itself was vibrating because the tenon wasn’t exactly central. A quick pass or two with the spindle gouge cured that, and then I started hollowing out the bowl with the bowl gouge and quickly discovered a few things:

  • I need a lamp in the corner of the shed pointed at the headstock. I had to jury-rig a torch to be able to see inside the bowl to see what I was doing. Daylight might help, but this was after dark here.
  • I really need to remove the tailstock to do this, it’s way too scary having your hands near a live center when worrying about catches in a bowl.
  • Being able to rotate the lathe stand in the shed would be a major bonus on any larger bowls. Happily it’s not bolted to the floor; less happily, the compressor and pillar drill would have to be moved which is awkward. Maybe I could put a shelf down at the feet of the lathe stand when I can get more plywood after the lockdown ends.
  • Bowl turning is a bit scary.

But after a while of taking small bites with the bowl gouge and then a final scraper pass, I was able to move on to sanding. Up from 120 to 400 grit, and then burnishing with a handfull of shavings – and doing that inside a bowl with just two fingers at high rpms is hilariously scary. I wanted to keep the colour light so I gave the bowl a coat of poppy seed oil (also food-safe, which is nice because I think this would make a good salt bowl).

And then a single coat of blonde shellac and I called it finished.

I’m rather pleased with that 🙂
I mean, the walls are too thick to be elegant and too uneven in thickness to be able to call the thickness a design choice, and I didn’t even get the bottom of the screw holes from the faceplate out of the rim, but for a first bowl, I’m happy with that 🙂

Now for that 11 inch by 4 inch blank in the timber storage box…
