To add another take on this, its possible to put the blade in what I would call the conventional way (teeth forward) but to still use it as a pull saw, as in using your front hand that is holding and...

I think you will find its not quite as simple as that for the properties of the material. The term or name 4140 only gives you a hint as to what the material properties actually are, that it should...

DC is what you need.

Something else i have come across since the previous post, and it does depend on the particular alloy of brass you are useing, is that the high heating levels created in TIG...

I bet theres a rule that says your sparky shouldnt have used a star picket! And him putting in a second one rather than useing the original doesnt sound right either (well not when talking about the...

China is in the ballpark for how fine a finish you really want. The most important thing is to have no high spots, the lows from the scratches wont be a problem as nothing can contact these and they...

I have seem some (most?) that work on variable capacitance. The other half of the plate of the capacitor is behind the measureing label in the face of the vernier and is useally a triangle in shape...

The WIA 150 is a great machine and will do the job well, but i'd stay well clear of the galv sheet and go with some Zincaneal, LOTS easier to weld! and if you are only going to use 1mm sheet anything...

Hi,

I dont really know whats inside your burner unit, but with the one i have built, it needed a hole size for your "jet" thats pretty close to what your useing! Another fellow told me at the...

Also an obvious thing is to make sure that where ever you have the saw sitting is FLAT, dont try to use it on the ground etc, and plenty of concrete floors in sheds arent flat. I have a makita cut...

Hi Al,

I see that you opened up the intake side of your blower to let it move a lil more air, but i'm wondering how far you have opened it up, dimensions??? or if you have just gone to the same as...

The 2nd pic would happen to be the one on the previous page as part of the 8 or so pics i provided the other day :rolleyes:

Schtoo,

Yes the unit runs a blower. Am useing the exhaust from a small industrial vacume cleaner that is connected to the back end of the 65mm pipe with a short piece of Skeet tubing. The vacume...

Wiht a lot of patience and a lot of cleanliness stainless can be soldered with regular solder, but it involves it being heated and tinned and rubbed and so on and so on and etc etc etc, and after...

Hi Barry,

The drum is actually an old 44 gal drum, yup a whole 200 liters :D

The actual entry to the furnace is a piece of 6" pipe lined with clay etc and reduced to maybe 3" i think a beer...

It's a lot easier to use than i guess it looks :) But then again aren't allll projects out of the shed supposed to be a lil over the top or excessive or over engineered in some way :wink:

And the last few... If anyone has any questions please feel free to ask!

Here's a few pics, sorry bout all the dirt etc but its been a few years since its been used!

Schtoo i adree with you about not being able to aford to buy a needle valve, let alone a twin!!! Mine cost me about $9.00 for brass fittings and the rest was a scrap block of Aluminium and some M6...

Schtoo, and others i guess...

I see you dont have compressed air... but, all the fiddleing about with a preheat etc to have enough heat inside to be able to get the oil to start combustion is just...

There are also small scotch brit/steelwool type cleaners that will fit over the wire in the welder and attempt to clean it as it is being fed, as the wire is drawn through the cleaner before it goes...

A MIG is your only option. OXY in panel beating, other than for shrinking and a few other jobs, is seldome used for actual welding, unless you are talking about from years ago before the availability...

Like a number of previous posts, you really have to choose the best type for what you will be doing.

Dont let anyone scare you off from buying a MIG, if you buy a good brand name unit you will not...

YES!, To do gasless mig, you still need to have the arc and puddle shielded from the air, usually done by the gas, but with gasless mig you use a special wire, Innershield, you dont need gas! the...

Buy as good as you can absolutely afford!!! Any good welder will do innershield, you only have to reverse the polarity on the output terminals. But a welder thats annoying to use will have you never...

Another thing that i have seen a friend of mine do, is to deliberatly stick the end of the welding electrode to the welding bench top to heat the rod up to make sure that there wasnt any unwanted...

This is always a point of contention, push, pull, drag etc, angle of hand piece, blah blah blah..... If you look at a dedicated machine set up for process welding you will most likely find that the...

Yes all that is behind the front panel on an Inverter TIG is a lil pot (variable resistor) BUT the electronics needed between that pot and the welding electrode, is FAR from so simple... I'd be...

Hi,

Only a few days ago i fixed a finger control (Amptrol) for a Lincoln tig for a friend, it was nothing more than a 10K pot and a micro switch, and this thing was worth some $500 odd dollars to...

Try here, am sure this is what you are after.

Panel Beaters, usually have heaps of bent roo bars, well out here anyway :) or you could try some auto gear box places, or maybe an Aviation repairer or engine shop, they frequently are changing...

Mig-O-Mag and Kemppi are also very good machines. For your budget i'd be trying to find a 2nd hand machine perhaps. But if you only want to do Steel and not Aluminium, you should be able to find a...

Silver solder and a lathe... Get the two fittings that you wish to join (that arent ment to go together) and turn a lil spigot on one fitting, and a place for this to sit or press into on the other,...

Silver solder and a lathe ;)

The furnace i have under the house is fueled mainly with old transmission fluid, as oil yeilds a lot more energy than gas and can be made a lot hotter if you wanna...

Looking good! But whats it for???

Wondering what the mould is made from???? When i last cast something we used green sand? (sand, bentonite, coal dust..), its been a while, and was a total of...

If you decide to use a Die on the bar, i'd make sure you buy a HSS Die rather than the usual Chrome Tungsten Alloy ones as it will last a lot longer, and i'd use liberal amounts of cutting fluid or...

Not sure what grade you are after, or even if it matters for what you are doing. But a good source of aluminium that i have used before for the same pourpose, is old Pistons, from all sorts of...

I have a WIA 150 and it does a great job even on larger stuff! and it occasionally has 0.9mm wire in it with no trouble. Am also a fan of Mig-o-Mag machines, and have also used these for some time...

^You can also get another variation, i think its called a Key Insert ????? Which is a threaded sleeve, it has thread on the inside and outside, you drill the correct size hole and tap a thread in it...

You really need to decide if you need or want to be able to weld Aluminium, that will be the biggest decision for your choice of machine, bar none! If you are talking an inverter style, instantly you...

Grahame may have extra info, but i'd be using nothing other than straight Argon and also back shielding, stainless is fussy stuff and can be even worse depending on the grade.:)

Copper TIG, easier than lots think, sometimes a colour variation depending on the chance of different alloys of ur material or filler, and is as easy as a few more amps, well quite a few more amps, i...

If you go to a decent Electro Plater, they will be able to do Nickle , chrome, silver gold etc etc etc plating, as a comparison, nickle is a lil more yellow than chrome. The people should know by...

Tis very standard practice to bore out a smaller pully to the size you want, most engineering places that sell them do this regularly. Your idea of a shim will also work fine, i'd make sure it is a...

My WIA machine has the factory fan fitted to blow air into the machine to aid in cooling. The greatest cooling effect is when you have the greatest pressure differential across the item to be cooled...

The mig welders that i have seen, as well as my own WIA, all have the fan blowing into the cabinet, and usually onto the transformer or rectifier, as these are the only areas that get hot and will be...

I have used the one that you mention, but only a very lil bit, but didnt notice the problems that Grahame mentions, but then again no kids had been at this one ;) I made a panbrake myself, if u have...
