Metal Working! Fitting, Machining, Welding, Sheet and General Metal Fab

[Xavo.au]

There's some crazy good stuff in here. Keep the pics coming!

I do a few bits and pieces for different projects of mine - Here are a couple:

Jerry can holders.

a man with cad! thats what i like to see!

with mig/tig/stick you can do near enough everything but if you dont need the mig, ie good a stick welding allready go tig/stick BOC make a nice little unit we had back at school and they were good, under $500 from memory too, excluding gas and pedal but it really comes down to practicality and use

 

[Urban DH]

machined up a quick hub body today, picks later, she come up good for a 5 min job!

Here's a pic of some ally welding

I need to learn to TIG weld.... I probably would've learnt if the machines at TAFE weren't buggered when I did my apprenticeship.

Just a rear bar I made for my old Patrol.

Looking at making a new tray for the old Hilux too. Maybe.

Cheers. I ripped off the shitty plastic one on the track, so I built this one over a couple of weekends from scratch. Didn't have any sort of design drawn, just winged it. God I miss my Patrol

Contaminated?

You sure you know what you're looking at?

 

[Urban DH]

Contaminated?

You sure you know what you're looking at?

is that not flux and shit around the weld, it looks not disimilar to zinc but its not

 

[muvro]

Nah, it's not flux, you don't use flux with A/C aluminum welding. it's just normal flaring. It just polishes off.

 

[Urban DH]

so what equipment have people got in their sheds?

i'll start

hare and forbes lathe
hare and forbes universal mill
power hacksaw
drill press
stick welder
mig/tig/stick ac/dc inveter welder
bench grinder
a compressor set up that has just the gauge and hose reel visible and a large old school pressure gauge wiha clock to match (i'll post a pick later, its pretty cool i think!)
lazerleveling system
air rattle gun
air grinder
100 and 120mm grinders
recipricating saw (scaryest fucking thing in the work to us on metal)
large hammer dill
cordless rattle gun
car rotisary
chain hoist
engine hoist
engine stand
large jacks
and more!

 

[stoo]

Fema 300A MIG
Old school arc
Oxy
Power hacksaw
Bramley bender
Cheap-arse air / hydraulic bender
Bar bender
20T shop press
Old mini metal lathe ( Hercus I think? )
Old ex-ordinance metal lathe ( Purcell New Visby )
Hafco HM46 Mill
Drill press
Bench grind / rag buff / wire
And all the usual little stuff.....

Does my workplace count as my shed if I use it on weekends for my own stuff?

I machined a Plenum for my turbo bike out of 6061 T6 Al. Started with this.... Solidworks 2011.

Many hours later on a manual Mill and Lathe it looks like this.

Just a tip for some of you guys, I've noticed looking around different threads that when people drill a hole in something they don
t chamfer it.

This is bad, chamfer every hole all the time, Break All Sharp Edges..... It makes it look like you care about the job.

thats well cool mate! no 100% sure where it sits or how it works but cool

I love the fack that you machined it manually! you gain much cred for that!

I'd second that too! just deburring things make the job look 1000x better!

 

[latheboy]

Thanks bud, it's a labour of love.... I live for this stuff, been designing and machining for the last 20 years ...
In the SW pic, the blue parts fit to the carbies and the air from the turbo goes in the black elbow.

Hardest part to machine was the fitting on the bottom .. It has an oval to round hole going through it ..

 

[Urban DH]

thats exactly how it should be! you're doing it for all the right reasons then!

ahh i see so basically a high tech fandangled inlet manifold then? and for a bike you say?

 

[latheboy]

You're basically right UDH, it's a box with 1 hole in and 4 out.

It fits to this and spreads the boost over the carbies equally.

You can only see the side of the plenum when fitted, It's under the rear of the tank.

I did everything on this bike other than weld the intercooler, I was a shitty Ally welded at the time.

 

[Urban DH]

That is Bad Ass! 4 cylinders you reckon? fark that must go like stink!

 

[latheboy]

It scares me when the boost comes on strong

Well done bud, you seem to know what you're doing.

Do you use K factores or bend tables?
The only thing I would change is the slots on the sides of the jerry can mount.
I would put radi (same R as the thickness of the material) in the 4 corners, this will save you a bit of money when getting laser cut.
Everytime the machine has to stop at a sharp corner it counts as a new cut.
If you have a Radi the machine thinks it's 1 long cut.
Laser cutters charge by number of cuts.

But it may come down to looks as well and may not have the style you want.
