< 2024-02-03 2024-02-07 >Let's try and make the escape wheel shaft. I think I will blue a piece of 3mm silver steel, because I recall that in the soft state it didn't turn very nicely.
The tricky part is workholding for the 2nd operation.
I think probably I want to make the long end first, and then somehow clamp on the 0.8mm diameter. Maybe I drill a 0.8mm hole in a piece of aluminium and then superglue it into the hole, and then I can at least make the right geometry, and then it just becomes a problem of extracting it from the aluminium? Let's go with that.
The first side went OK, not great. I need sharper tooling. I only have one tool with an actually sharp radius, it is a random HSS one, and it is not ground very well. I should make an actually sharp tool of some sort.
And supergluing the part into the aluminium doesn't seem to be going very well, the glue is not setting, maybe because there is no air getting in? I'll just leave it for a long time.
The glue broke off quite early :(. And, strangely, the part is scrapped because the 0.4mm diameter pivot piece also broke off. I don't know if the pivot was all that was actually glued properly, or if after the glue broke, the piece became loose, allowing the pivot to get pressed against the inside of the hole and then break off.
I could really do with some small collets for holding these small shafts.
Next time:
So I've been playing with sending g-code, pausing, resetting, etc.
It seems that the UGS concept of "play" is cycle start, "pause" is feed hold, and "stop" is soft-reset.
However, soft-reset rests all your active G codes, and I'm not sure that's what I want. I probably just want a way to flush the input buffer without resetting G codes, no?
Although, for that matter, M2 also resets your G codes.
