Thanks for all the extra info guys. I really had no idea about the intricacies of the whole plywood scene. I've been a metalworker for ages, but only recently developing an interest for woodwork...

Good post Ross - the confusion between Birch and Russian ply seems evident in quite a few youtube videos. In fact it seems the terms are used interchangeably and it good to actually know what the...

Thanks Dave, that's good info which I'll follow up. It sounds like you're in the plywood import industry?
Apart from the obvious quality considerations - it would be really nice to know where good...

Exactly my fear... I'll chase some of the other suppliers suggested.
Thanks

I had another look in bunnings the other day, and the number of sheets that were warped in some way was a real worry. I'm talking about the AA marine ply here. Is this just poor storage/treatment or...

He also does a few other simple table and workshop furniture builds out of scrap materials on his youtube channel.

Thanks Justin, my first thought was grab some marine ply from bunnies, but the price made me think about it for a bit.
Elan/Glenn - I couldn't find the poplar version, but I see BB birch ply that...

Hi, I've been reading through the various threads on Australian plywood - I'm after an update for 2016.
My request is prompted by some binge watching of Matthias Wandal's youtube channel...

The challenge is to find something flat and immobile to lever against. One option you may not have thought of is to pin down the middle of the frame by using lengths of wood extending down from the...

I've got that same compressor, not sure how long - maybe a couple of years now and its been great. $399 I think it was. Wish it had a bigger receiver tank though.
Haven't changed the oil yet - was...

Have a look at this guy's build. He talks about his earthing arrangement in this video.

Bummer. Hopefully after repairs it will last another 6? years. It'll be interesting to see what your total cost of ownership is per year and how that stacks up the Millers and Lincolns of the world....

I just got my first box of goodies from Smith and Arrow - I'm more than happy. Flaps disks, cut off disks, drill bits. All looks good and a couple of freebs thrown in which is always nice and it's...

I was having a good look at one of those portable milwaukee bandsaws the other day. They look great, but like has been mentioned above the practicalities of holding one for any appreciable time just...

Yeah, you're not a welder until you stick 2 coke cans to each other :D
Actually, I seem to remember that the challenge now is not so much welding two cans end on end, but instead, cut one can in...

Rusty - that's a fair point to make, particularly with more and more fine print accompanying every sale, but I think that's a negative spin on it at least in this situation. I don't know for sure,...

Gotcha... I had my mind floor joists.
Personally I'd go for the RHS, particularly if you're going to see it (think protruding screws, etc.) and I'd find some end caps to suit.
- Mick

I probably would've done the same - (wire brush rather than a converter) - I was curious, because I know some guys actually encourage the flash rust with the theory that a converter will bond better....

I have to agree, excel is very useful program. If you claim tax on your machines then it's easy also to put together a depreciation schedule, so satisfying this need too.

If you put pictures in...

Nothing more frustrating than waiting for a machine !! This is why machines won't take over the world... imagine terminator with a low duty cycle.

I'm looking forward to your progress on this one...

I've got a tokentools AC/DC 4 in 1 TIG as well as a tokentools 210 synergic MIG. I can fully recommend the machines and the after sales support. Given such a good track record, I would also hazard a...

I'm getting lost around the part where you mention pedestal fan... a picture would be good.
Maybe go back to your original 2mm stock tube and get some guidance on how to make that weld good. Picture...

Grahame - what's with the stainless steel thing? did I miss something?

Approach depends a bit on whether it's an outside corner joint or an internal (fillet) joint, but I think the response is the same.
I'd use the 2mm electrode.
In this case, zig zag weaving will...

And lots of good photos showing good vs bad
- Mick

Only issue with trying to do the outside corner joint as being discussed above is that arc welding the 3mm material will test your skills. Depending on the application #1 or #2 from your drawing...

Geez, where's the can do attitude guys? :C

Seriously though - thanks, it sounds like a few of you have tried this sort of thing and maybe this one is best left for someone else to do.

- Mick

I've got a bullbar and rear bar on my Hilux, both powdercoated steel made by ARB. Both are getting rusty and require a bit of refurbishment. I pulled the rear bar off this arvo and the rust was...

Thanks Karl, even though you typed 'LNG', I read 'LPG' in your initial post. In any case I wasn't aware of the practical differences - interesting.
- Mick

That's really interesting. I remember one incident where a guy rolled a taxi. He got out quick as a flash and basically told bystanders to run for it as "she's going to blow". Watching too many stunt...

Yeah, I guess that's the edge that's visible in the original photo - plain as day.

It's all too easy to say that it was used wrongly or it was cheap, or came from some generic cheapo nameless...

Sounds logical... I was think of some sort of automatic system, but that's over complicating it.
I figure that if work hardening of the baffles was an issue, then boat fuel tanks would have the same...

I've heard (but don't know for sure) that some stainless steels have issues, particularly for long tanks like yours, where sloshing fuel hits the baffles and can work harden them over time,...

You might want to be more specific about how you're welding it too. Have a look at the recent thread about tig welding gal as well as other older threads too. If you're stick welding just set up a...

Now all you have to do is cut it all up into bits, section and etch the welds and see how good the welds are :D

Just let it air cool - what's the hurry?

Have a look at my last post on page 1. This is the sort of situation I was referring to
- Mick

Wow, I've got a glue gun that probably would do a better job than that - scary.

Name and shame I reckon - doesn't matter if you're pulling out trees or not, that sort of thing just isn't...

I dunno about that, particularly if the student has some prior failures to help focus the mind. In the hands of a good teacher they will very quickly pick up on what is required... then its about...

It is often a problem when stick welding fillets on thin material, in that it is tricky to achieve penetration down into the root of the fillet without burning through the walls of the base metal on...

Yes the 1.6mm rods are tricky but do work well with very thin material. Not necessary in this case and will make it harder.
I was thinking of just sticking my gopro in a welding helmet - anyone...

Personally, I'd do your first pic, but swap 3 and 4 around. The advantage of starting like I suggested, is that you end on a flat spot right on top of the start of your previous weld, with a bit of...

Starting to look pretty good there gazza, still not cleaning off the metal enough in my opinion though.
Both you and Legion don't seem to tie in those corners. I find the best way is to either
a)...

Maybe, or maybe just make sure you are welding back from the top of the gap a bit more?

Hey Legion, great work with those tests and pics :2tsup:

I went straight to the photos and looked at the low amp ones and thought that they looked like a dog's breakfast... but that was quickly...

Gazza, it's hard to tell from the front-on photos, but if you look at photo six, it looks like fillet weld on the right hand side (not the one at the front) is crowned high and I doubt there's much...

Firstly Gazza I got to say those welds are looking way better. That rusty powder shows a temporary loss of shielding gas (change in breeze ?). The welds look a bit cold - need more amperage.
With...

In some of gazza's other threads it was pretty clear to me that this is one of the main culprits. Also in another thread (I think) gazza mentioned that he had poor eyesight. So like Karl says... fix...

You have it right Gazza, for TiG the torch/tungsten should be on the -ve and the earth clamp connected to +ve.
If they were reversed then yes, that would explain a few things, but I don't think...
