OV9

I made DJ's little chair pieces today. I had planned to cut them out with my mate's plasma cutter, but as I had to go to his factory to collect it, and he wasn't there, I figured why not make use of the big machines...

Here are the finished pieces with a pound coin for scale


Here are the various bits of kit used in the process:
To punch out the centre holes -


Giant guillotine to cut the blanks -


Tilt press to cut out the shapes (amazing bit of kit BTW) -


Giant fly press to flatten everything after grinding -


And finally, the pillar drill for the bolt holes -


Ain't no kill like overkill

Images aren’t showing (for me at least)

Better?

Looks like you had a fun day

I don’t even know what a tilt-press is!

Fabricating things from scratch is CAF.

It's like a giant 80 tonne punch with a big right angled die. The trick is that the table is tilt-able in 3 dimensions (and has pop-up bits for more complicated shapes). It has capabilities way beyond my skill and experience. Oh, and even second hand, it's about £40k.

I can only see the last pic.

The last time I was at A and P Tyne about 10 years ago they still had a lathe about 20 metres long for tailshafts

In China they had huge vertical mills making massive flanges which was an impressive hit of kit. The table was about 1 metre high and the rest of the base and bed about 5 metres down!!

This video is fascinating and shows how old technology is still very important, the clever Germans doing what they do best.

Dave!

I am very grateful for your help and also glad that you got to play with some proper toys!

Nice vid, thanks Dave. I feel suitably small again

Very cool video and bits, making and machining stuff is a skill I wish I had, a semester of it at uni showed me it was a bit too much like hard work though.

After uni I worked for a stainless steel fabrication place (mainly for boats). They had a CNC tube bender which was pretty mesmerising to watch. Probably old tech now, but at the time it was one of only a few in Europe IIRC.

Looked exactly like this:

Cool, Ariel should be able to make a one piece chassis with one of those!

For whatever reason only the first and last of Nef's pictures are visible to me on both PC and Android phone. Very odd.

Same.

Is that better?

Nope.
