Random slightly cool stuff you built but not worth its own thread, thread

The Colin Chapman mantra that a Lotus should only be strong enough to last until the end of the race, probably shouldn't apply to anything else.  Lighten everything until it breaks, then make the replacement a little bit stronger, perhaps not the best design ethos.

Italian bicycles are the same

tiny little non functional brakes, because why would you want to slow down in a race

This is my thinking too. We have a joke in the office that 1 + 1 = 4 but we call it 10 to give us a decent margin of safety.

Magnesium extrusion container I designed has a safety factor of less than 2.

Any more and it would have been unsafe to operate due to being too heavy. Had to use some pretty good tricks of engineering design to actually make it possible

About 900 MPa on the liner wall

what does it do there Anton?

[Yowzer]

Extrudes magnesium?

Made some lamps.

$2 Unkown Riley grille from the tards. Bit of a coke and tin foil clean to remove the worst of the grot. Dismantled LED fishtank lamp. Boom!

 

Plus, sheep skull, found the other weekend tiki touring around the Coromandel. Dismantled bicycle tail lamp (stupid mounts broke, so sitting around). Bit of tape and a cork. Boom/Hail Santa etc

That skull would be an ideal night light put it on a motion sensor next to your kids bed.

Made a magneto tester out of a sewing machine. Wanted the variable speed function that my angle grinder based test rig couldn't provide

Brilliant. Well done...
There's money to be made by being known as the guy who fettles magnetos. So many bike projects stalled cos they cant find/fix em...

Interesting to know... I'm an aircraft mechanic so still deal in an industry where magnetos are considered state of the art! 

Unfortunately the sewing machine mag tester struggled to turn over impulse couplings so it was eventually superceded by a more powerful and slightly less silly polisher-based unit (that spins the wrong way for most mags hence the drive tapped off the back)

Yeah years ago there was an old bloke who was the go-to guy for old pre-war BSAs, vintage cars etc. He was renowned as a magneto expert and was flown to India to sort out Maharaja's old Rolls Royces etc. He'll be long gone now prob...

now you can convert it to a two stroke sewing machine for the mrs.

Forged up a squirrel roaster 

 

Roasting fork on one end. Billy hook on other

[Muncie]

Built this for an old workmate who absolutely is the epitome of "everything is a hammer" so much so all torque wrenches got referred to as torque hammers on site.

It still functions and will dampen shock if you adjust it down , pretty cool kind of dont want to give it to him.

[Muncie]

Before anyone freaks out yes its a expensive norbar wrench but its been on production line for a few years and would no longer hold a calibration this was the perfect retirement for it.

My son has wanted a cubby house / tiny house for ages.

According to him it needed a Mezzanine, to look old fashioned, and be good for hiding out in.

This is as close to the design brief as I could manage.

 

 

[Kimjon]

Mate wanted a biltong slicer, so I'm making him this. Still a work in progress...
