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

Start of the first one I've done with my own stabilised wood. 

Needs a shit load more polishing but liking it so far.

Did the resin get deep into the wood?

[beachlander]

The stabilising resin? 

Seems to have gone rigtt into the centre, but it's a hard wood so might not have been the best test. 

The red resin is just on top of it, this was the piece I used.

First stockcar. Only pic I have of it. At that stage it was the oldest standard stock racing in the country. This pic was in 2005. It was built in 1967. Powered by E31 Pacer 245 Hemi. Had a habit of heat seizing.

My boy loves checking the mail box every day so I surprised him with this.

he thinks the coolest part it taking letters out of the arse.

should rust up good.

How do you clean the cylinder for safe cutting? Pig looks sweet. 

[JoKer]

run water through it for a day? or purge it with inert gas : I know there's an expert way  to do this & a Welder Barry will be along soon

[Ghostchips]

A guy i know fills them with soapy water for an hour or 2 & drains it.  Soap binds the gas like it's an oil.

[JoKer]

have you seen the 'crafty Russian' that likes to use those Freon tanks for making dumb facebook "diy" stuffs?

He just vents them atmo (like every time)

I've blocked or snoozed most those pages so sorry cant find a link at the mo'

edit : a bit like this (and just as hazardouz)

I removed the valve and left it upside down out side for about six months before I used it .

i did drain the big bottles when I made a cannon, don’t get the dye or smelly stuff on ya or you will stink for weeks.

then lots of hot soapy water and store upside down, lpg heavy than air etc

I just fill mine with water and leave them for a day. Empty them out and cut/ weld away.

Some of my pigs.

They are quite cool to watch as they weather. The rusty one took about 8 weeks to get a nice even coat.

I brought my son this tempered glass basketball backboard for his birthday this week.

Problem is I had no idea how monstrous it was in size/weight at the time of purchase (online). Slapping it up on a bit of 2" pipe wasn't going to happen.

So:

Trademe to the rescue again. An ex stadium spotlight pole at a whooping 180mm diameter, 10mm wall thickness and 5.9m length... "honest truth officer, I'm only moving it just down the road"

Some "School-C" level mathematics and equivalent drawing talents soon had a design in place. Let's just say it has a generous factor of safety when I did the calculations for bending stress...

And many hours later...cut and fitted, v notched for multiple weld passes...and shitted together using an arc welder. Not my finest work, I certainly wont be sitting any gasline or food grade welding tickets this week that's for sure... but I'm pretty confident it's not going to brake anytime soon.

That's as far as I got today. Been up since 4.00am and just sat down now, so 14hrs of picking up and getting shit done today. Must be beer o'clock???

[Positive Ape]

that enginerding is so cool. No guess-work allowed. So in the first pic you are calculating the strength of the pole?

[Kimjon]

Very crudely. I only did a basic calculation with 100kg hanging on the hoop. Ignoring a heap of things just to get a feel for it. 

If you gave it a high stress value on the less than ideal welded joint, and a high shock value on the load being applied...it will still easily hold 25 people hanging on it (ignoring that the ground would fail first).

Proof test?
