Had a bit more shop time after work today   :dremel:

The flywheel-in-making was still sitting on the lathe as I left it Sunday, so I drilled and reamed it for the axle, trepanned the face to thin the web  and then flipped the whole lot around in the chuck, using bits of cardboard to prevent damage to the finished rim:


Then I faced off the excess aluminium, and trepanned this side as well:


Next up will be a bit of work on the rotary table, but I have to calculate a couple of angles and offsets first...

Now thats an interest, little bit held in a support gizmo held in the tool post. Take it the little bit is for the finer work and the support is to add some sense of rigidness. I like it, clever

Thanks Robert  :beer:
:lol: You're giving me way too much credit there for being "clever"...
Actually, I got a job lot of good quality 4mm x100mm long HSS round blanks a year or two ago for a VERY reasonable price, and that's my way of using them.  The "holder" is a useless-to-me carbide tipped internal threading tool that I drilled and threaded to mount them in.  I just cut the HSS blanks in two or three pieces, mount them in the holder and grind away to make up small toolbits as I need them - the holder makes it easy to grind them as well as use them  :dremel:
Much quicker and cheaper than grinding bits out of bigger pieces of HSS  :thumbup:
I don't even bother locking the height-adjuster screw on the QCTP holder I use it in; I just use it to screw the holder up or down to get the tip at the correct height and lock up & go.  But you are right, it is convenient to get into close corners with the small bits while maintaining a semblance of rigidity. In the photo there's a better view of the holder, a new HSS blank, a bit with one end ground up to make a very sharp shoulder on a turned bit in brass, and finally another bit with one side ground to part 2mm grooves in aluminium and the other end - though rotated out of view - is for single-point threading fine 60 degree threads.:

There are more bits, but all variations on the same theme; different widths of grooving bits for different metals, radius bits  and threading and V-bits.

No shop today; when I got home it was raining, so I popped a beer, fired up the Cracker loco and parked on the stoep playing trains & enjoying the cool damp breeze that's broken the last couple of day's 37C+ and humid heat  :D  Sometimes it's nice to just mellow out...

Did get a quick snap of a rather battered arachnid though - this one must have lost a fight somewhere...  This is a species of spider that I actively encourage to inhabit my house and shop, as they prey on all kinds of ants, insects, other spiders, does not spin webs and are completely harmless to household pets and other humans  :D:
