What did you machine today?

[Dave C]

Your lathe is a sideways mill, it just doesn't know it.

You should see some of the stunts I've pulled off on the lathe

I'd like to see some of them, the safe ones.

Hey, I made my Suburbaneez fly cutter tool bit in the lathe. I had to mill a compound angle for the carbide insert. I couldn't do that on the mill yet so I used my Atlas Milling Attachment on the lathe. It sure is nice to have a lathe.

I was using the mill today to 'turn' the rust off a 1" length of 8" diameter pipe. The mill's got a 10" 4 jaw chuck that clamps to the 8" rotary table. The 11" swing Hardinge lathe has got a 5" chuck .

After I came in from the shed I went on to fleabay and ordered an 8" 4 jaw chuck, from the same importer that the mill's one came from, to fit to the Hardinge. I'd been meaning to do it for some time and this finally prompted me.

Updated my hand tapping machine. Made up a new extension and added a 7/16 sockets to drive the tap holders.

After using the machine on the tool holders last week I realized it needed some updates

Just made a stand for the Aciera's cones and clamps.
60x120 aluminum section and melamine for support.
I saw this shelf on an ebay listing and liked the idea of clamps underneath.

Nice!

[Mark Rand]

Nice. I might copy that idea for clamps.

PS:- Rotabroach/annular cutters are wonderful things aren't they?

Started tidying and reorganising my workshop in the futile search for more space. Naturally I got sidetracked by some minor detail and ended up machining what looks like an aluminium suppository!



I have an 18V angle grinder that comes in a storage case. In the blow-mould plastic liner, they provide a spindle to store your spare grinding discs. That's great until you pick the case up and they fall everywhere. This part goes in the back of the spindle to reinforce it and then takes an M8 threaded rod with a washer and a wing nut on the top to retain the discs. M8's massively overkill....but that's what I had lying about. The part looks fairly straight in the picture but it tapers by about 5mm. Nose dimension and tail dimension (just before the last shoulder) are accurate and the middle is just tapered by slowly unwinding the cross slide as the carriage power fed. The groove before the shoulder is a necessary precision feature.....and not at all a result of knocking the lever from power feed to cross feed accidentally *cough*

Some deep hole boring, 4mm drill and 150mm depth.
Best part of it? Material was stainless!

ER collet on toolpost is a must in a job like this, quick retract and you can adjust the drill hangout.

Interesting. Straight shank and through hole presumably?

Yeah, straight shank with trough hole and square sleeve over it.
(Collet chuck was probably less than 10usd from ebay)

Turned some really short flanged shafts to mount some 16x8x5 bearings onto some square steel for a bump tool. Seemed to get fairly good results turning the shaft to 8mm and then freezing them to get them in. Next up is some relief on the bar they mount to - so they will spin. I know I could probably achieve this quicker and easier by just shoving a washer between the shaft and the square steel, but I've got it in my head to machine a nice annular relief....so that's what I'm going to do.

Made a little 1" aluminum vise with felt jaws to hold micrometers. The stand is a steel disk with a cheap tripod ball head screwed to it. The vise has a 1/4-20 threaded hole to accept the tripod screw.
