Te Pahu, deep within the economic exclusion zone.

Hey for all those in the Waikato that want to learn a new skill, brush up on some skills etc im happy to have a couple people over and do some lessons. Can cover; Mig, gasless and solid wire Tig, mild steel stainless and basics of Ali Arc, all positions. I just want people to be able to do more and make more stuff themselves. If you have a paticular skill or project we can dial some lessons around that no problem.

As above, brought Shilohs old mig as a gasless only machine. As most people I had only had bad experiences with gasless migs and then applied that opinion to all gasless options. Worked for a place that had a goat farm so welding no prep galv pipe all day and saw how good gasless machine could be for certain jobs. Insert the dairy shed special; -Boc Raptor 160a with all gas parts removed. -Knurled roller -0.9mm ESAB Coreshield 15 gasless mig wire 5kg Is a great combination. Its not for everyone, its not cheap but it serves a purpose that is painful and is cost effective for what it can do. 10 amp so it can run off poor dairy shed wiring and 30m of extension leads. The key for why you would use gasless for dairy work is that all your work is on galvanised pipe under 5mm so you dont need the grunt and because you dont have a gas, the flames/smoke that comes off the galv cant affect the gas if there is none. Basically all your issues you have when welding no prep galv with gas such as green flames, random popping throwing zinc everywhere including down inside overalls, holes in your weld are to do with using gas. Ive always used arc for everything mobile but it can be a pain if your only doing thin work and isnt that fast at all. Here is a job I did this week, breast rail for dairy cows which sits over the top of their shoulders to prevent the new milkers trying to jump out over the top of the rail in front of them. Vertical bars are the pieces cut out of the old dairy shed which was replaced in 2011. Horiziontal bar is the old bore pipe. Minimal prep on the galv, none on the bore pipe welding up. Also a jig I made up for doing fast 90 degree pipe connections. @RXFORD will be happy to see his neighbours clamps still going hard. Works really well for keeping the 2 pipes in the same plane and 90 degrees. And some rawdog testing setting it up. No cleaning, both 2nd hand pieces of material pulled out of the long grass/ground. Not bad penetration.

Fun fact, the base models dont have ABS, can confirm have had a few poop my pants moments recently sledging in the rain.

Yeah just found one. Wasnt in too bad condition just been left outside for a few years and tyre popped trying to pump it up.

My grandads wheelbarrow. Was a man that did everything by hand on a hilly property with the wheelbarrow. Had mixed up many cubes of concrete until he got too soft at 87 then he brought a concrete mixer. Was a little worse for wear and tyre was toast so disassembled for a blast and paint down the line, factory colour tub and frame in chassis black. Spent $10 more then a garbage tyre from M10 on a 3.00x8 Shinko scooter tyre, was a bitch to get on but now have a tyre even when flat that has a stiff enough carcass to be pushed around. Good for 100kg at over 80kph so good enough for home. Button head stainless cap screws because im shallow and like stuff like that Is going down to my sister in Gisborne so good to see it get another life.

Got taken for a blat in this earlier in the week and oh boy is it rapid. Such short gearing, just comes on boost with all the revs and just keeps going through gears at pace. 10/10 would trade again, makes me wish for more close ratio gears in my life.

Have done a few nights for the local structural/ heavy transport fella and he gas flux core for everything. Shits amazing for 5mm and up just melts in, heaps of penetration and no splatter. Weld speed is about twice that of solid wire, great for positional too. I brought a 5kg roll for home which I have played around with a bit, ill take a pic of the label tomorrow. Not something a normal person would need at home but for reskinning a truck bed or smashing out some portals for a building, super invaluable.

Sounds like a great excuse for a large sump with a 2 stroke detroit dewatering pump. You care about your neighbours so it has a muffler but it mostly just rattles around on top.

0.9mm is quite a common compromise wire size. Do alot of solid core mig at work and its my go to for a little bit of everything. Would have gone through over half a ton of it over the last 3 years. I do find its quite lacking at anything big but if I do have 10 and 12mm work to do ill chuck a roll of 1.2mm on for the occasion. 0.9mm can do comfortably about 2mm to 8mm with correct prep all day.

We had a sausage roll for lunch, nothing is impossible.

Have a look at this guys youtube page. Is a friends Dad who is also president for the BOP club has a full build explaining how hes done everything. Super clever dude making do with basic tools me and @Beaver got the full rundown when we watched the racing in Te Awamutu. Bloody quick too. https://youtube.com/@bazzasgarage1922

If its only for tungstens a green wheel is the one, also helps with contamination as only gets used for 1 job.

Yep we had at the same where I did my apprenticeship too, is a bloody awesome machine. Height adjustment is awesome and heaps of power too.

Great choice in tool, up there with one of the most common tools I use. One thing to pay attention to is that ideally you want to be doing your linishing over a rubber wheel is much quieter and leaves a better finish. Alot of the cheaper ones arent really linishers as such they are just belt sanders stood upright. With a bit of trimming you can rotate then to face outwards instead of upright but having an aluminium roller to linish against is a bit shit. https://www.bunnings.co.nz/ozito-240w-bench-grinder-and-belt-sander_p0323486 ^is your cheapest option at $120, they are fine very underpowered and need sander roatated to get best use out of them. They do work though and if money is tight they are a good stepping stone machine. https://www.machineryhouse.co.nz/g1590 ^ Is an option thats come into the market in the last couple of years, good design with belt pointing out and you can see the rubber wheel at the front. About $550. https://nzsafetyblackwoods.co.nz/en/linishall-bench-grinder-bg8l-each--01670411 ^About $700. Are a very good machine is what I have at home, takes a bit to spin up but has a fair amount of grunt. Are a very common machine most engineering shops have multiples of them scattered everywhere. Not so good for production material removal as are lacking in power but good for everything else. 10/10 would trade again. As far as buying 2nd hand I would be cautious and know the value of what gear is worth new the market is cooked. Was watching the bigger brother linishall 3ph linisher on trademe, it sold for $450 more then what they are worth brand new. See the same thing happen at machinery auctions as well. Main thing to take away is that whatever you buy get good consumables. Most grinding/sanding tools issues can be masked to a certain extent by installing good consumables. I buy most of my consumables through PPS, there red VSM Ceramic linishing belts are awesome last for ages and keep there edge well and arent that expensive. Dont even bother using the brown belts you can get from aliexpress and what they come with from the factory they suck shit. Might as well rub your parts with a brick they both remove about the same amount of material. Let me know if you want more info or if ive missed something.
