For the little bit of milling I do on the South Bend I used to put the endmills in one of the Jacobs headstock chucks I got with the lathe.
Decided to make a MT3 weldon type endmill holder and drawbar for the spindle, so first job for the taper attachment.
Quite happy with te result. Only 0.005mm runout( well less than 0.01 anyway) on the endmills.
Don't know what grade steel it is exactly, but it's from an old LandRover 110 halfshaft so should be something like EN19 I believe.

Made a top cover for my parking brake earlier this week and thought the brake reservoir looked a bit plain in comparison.
So cut a couple of blocks of alu and into the Chiron they went.
First side milled.
Because the sides are all curved I had to make a jig to hold them for machining the other side.
Second side done and pre anodising.
Post anodising
Brought home and laser etched.
And fitted to the bike

Not reassuring, hope it picks up.

Did a prototype footpeg didn't have any Aluminium so as it is just a test I did it in Acetal, well top half anyway, will do the rest tomorrow hopefully.
Also made a couple of jigs up for doing the back end of it.
Went to anodise the jigs and found the boiling pan (and my plasma table) to be rather cool

Same here effecting everyone I reckon

We are normally booked up right up to Christmas with motorcycle repairs.
Still work in but definitely not as busy as last year.

Well due to it being plastic the second op didn't go a planned. I had thought I may have trouble and hence why I said "will do the rest tomorrow hopefully."
It did as I suspected and jumped out of the vice due to the plastic relaxing under the clamping pressure. That wouldn't happen with the aluminium but I had a think about it and gripped a different way and managed to get the rest of the underside done, albeit with screw ups intact Still it let me know it will work and the revised clamping method will be used for the real one even though it probably wouldn't be required.
Pic from the top showing the overall shape.
Pic from below showing the screwup but also showing towards the left side that the 3D milling will give a good enough finish.

I heard a couple of coach/minibus/taxi operators in the cafe today, saying how bad things have been all year and its not even picked up in December.Same here effecting everyone I reckon
Just finished machining stage 1 of @DAPPH layshaft thing for his lathe. Least i can do with all the help he gives me. Never need an excuse to play with my lathe 
DRO proved handy at last.
Annoyingly though I made all the bearing recesses to within a tenth in depth only to find that two of the ball races were wider than the other two. Only a small amount but strange as they were from the same supplier.

Got a piece of alu and had a go at making the right side footpeg. Came out ok although I snapped the 5mm ballnose half way through the top half roughing so had to rake in the drawer and found a 3/16" HSS one and got the job finished.
New peg on left previous on right.
Side view showing the difference in profile, new is much slimmer which I like better.

Having to relearn a lot as I havent used lathe for about a year! Finish was better but slightly over size I had to do another cut.
I bloody love using carbide boring bars, the little 8mm one can take decent cuts down a reasonable hole. Had to slow it right down to 75rpm to cut the groove, I need a bigger pulley to give it more power!
