Thread: Made some chisels this week.

There a bit rough and I first ground the longer ones but in the end thought I may as well do it short and go back to the grinder if I need more .

I bought a set of the D-way beading tools, but didn't really like them any better than just rolling the beads with the gouge, which I was having to do to tidy up those done by the D-ways anyways. But one nice thing I liked about the the D-way beaders was the high polish on the flutes.

With the advice of Hughie, I've been making some short fluted bowl gouges lately from various steels and found that to get from the initial grind to a flute finish that I was satisfied with a hard power hone with abrasive paste was best for that. Here is what I use...

Thanks Neil . That’s a good idea . Abrasive paste on a wooden form in the lathe ! I was wanting to polish the inside flutes of the new Thompson detail spindles and was looking at my grinders wondering what to do . I gave up and used sandpaper . I didn’t think of the lathe and a wooden form . My pink shaping stones leave a nice enough finish I think as I did on the beading tools but I wasn’t wanting to free hand grind the nice new detail gouges . Nice as they are the flutes were quite striated when I got them. I ended up just sanding the first 10 mm smooth .

What paste has you or Hughie recommended? Maybe abrasive wax would work from the buffing wheel? I have a few of those in various colour codes for the grit but don’t remember which colour is what .

Rob I used MDF for a wheel as deforms quickly and will absorb the paste as well. I use a fine valve grinding paste, unsure of its grit. It would have to be up around 400grit and it cuts darn well [ made in Germany]. Use a little and run the mdf wheel slow till its impregnated, then you can up the speed some.

I use black or brown on the power hone and finish off with green chromium oxide on the rag wheel. All of my gouges periodically get a return visit to the rag wheel to maintain and extend the polish in their flutes...

My hard hone begun life polishing out the grinding tracs left in the old P&N gouges. Some of those arrived looking like a freshly ploughed paddock. Doug Thompson's gouges also come needing some work on them before use, IME.

Doug's V10 steel is an excellent choice for a production turner as they will keep and edge longer than any other readily available and reasonably affordable gouge steel, regardless of heat treatment method. So, definitely worth doing the extra work to polish their flutes, IMO.

So I put the box on its back and made that slotted bit to let the thin stone through and shaped it to a round with the diamond tool.

Rob, are those pink wheels the type that go on chainsaw chain sharpeners?

Following Hughie's example, I begun my flute cuts with a thin cut off wheels on a angle grinder (right) and then refined with a profiled wider wheel on the left....

Later on I used a chainsaw chain sharpener with the pink wheels to refine the flute shape...

That worked well, but the only issue there was getting a wheel that was wide enough and would also fit on the machine for the wider flutes. I think the widest I could get is 6mm. Do you have a source for your pink wheels that come any wider than that?

Thank you Hughie . I’ll have to give it a try on my mini lathe which has speed control and reverse . It sounds good for the flutes. I may see how the wax goes first. I also have bags of silica carbide I think in 120 and 80 grit I could possibly mix with some wax. It’s a black grit I use for flattening honing stones on glass plate. That may work as well?

Neil . The pink wheels are a saw sharpening wheel I got from a supplier in Sydney who posts stuff out . I think they’re 200 diameter . I’ll check . And they come in a wide range of thicknesses last time I looked. I last bought a few of them ten years ago. From here I’m pretty sure . I’ll have a closer look tonight.
