What is the input rating for the welder? I have found they are often sold with a smaller plug what what they actually require for full output.

Really good explanation, even a lot of machinists don't really understand the different chip breaker geometry's available and how to use them. We mainly run TNMG's at work and i keep about a dozen...

I have a production job coming up for my turret lathe and it will be much easier if i can find a couple of tap holders. If anyone has some 1" or smaller shank ones collecting dust that they want to...

Maybe where you are but one of our 2 steelmills is about to shutdown its blast furnace, and is going to electric arc and direct reduced iron. I'm actually expecting local scrap prices to improve once...

Keep in mind guys that the price for large loads and high volume sellers of scrap is significantly (3-4X) more than what your local scrap yard will pay for half a ute load. what seems way above scrap...

not for 20+ years, currently owned by ESAB a publicly listed American company.


We run mainly late model Harris regulators , Comet 3 hand torches, and Harris cutting tips at work. they all seem...

Where did you get that information? Bareco's website says 1040.

99% sure there is no import duty on machine tools, as we have no industry to protect. GST is 10% of purchase price + shipping. that shipping cost seems very cheap for a item that size.

Its hard to answer what lube is correct for your grinder, it depends on the manufacturer, but something is better than nothing. for example my 8" wheel SJ12 uses grease, our 10" zocca at work uses...

chipping is normally caused by chip jamming or lack of rigidity.

Elan is right about the colour, I have see a lot of variations even from the same supplier.

Some pics might help diagnosing some of your machining issues.

We have differing opinions on specialty steel:U. for me its Monel, Inconel, Nitronic and similar. 4140 is just a normal day at the office.

Vulcan and Voestalpine are the 2 major engineering steel...

Its not marketing BS the older APxx inserts wont fit in the newer style bodies. At least for Sumitomo and Kyocera, Iscar still make Apxx tools but not sure if they are actually compatible with...

well i got confused with something else. i checked my collection and don't have any left hands. We got a 2" head and chasers from mick moyles in sydney, they might be worth a try.

Or this mob in...

We had a Rebel 215 in our site ute and it wasn't very reliable, it went back for repairs a few times, i know once the screen stopped working. It was replaced by a WIA which has been much better.

Do you have a left hand head? they are pretty rare.

I have a 6" vertex vice for my mill at home, it's not perfect but it does the job, the quality is what i expect to get for the price point. I use OML modular vices at work and they are defiantly a...

I was prepared to do this when i went over to the USA for IMTS in 2022, took cheap clothes i was prepared to bin if i needed room for catalogs or other goodies.

lots off cools stuff in the USA, I have often considered organizing a container load.

Repeat-o-meters are pretty easy to build, for a one off use it is also pretty easy to macgyver something up.

that was cheap, i have been looking for a mitutoyo or tesa head in that same style and they are normally $300-500 USD, ended up with a couple of plunger ones because they were only $50 each.

Its surprising how much steel can move. black bar is generally the most stable, peeled bar can be really bad, the bar peeling process tends to induce a lot of stress on the outside surface of the bar.

the wheels on both of ours are type 5's no issue grinding on the face, but we normally only finish on these grinders and rough on a normal bench grinder.

Are you 100% sure a 200mm wheel will not...

That thread drawing from the 3rd edition black book absolutely triggers me. none of the calculations shown will give you the correct thread depth for cutting a thread with commercial full profile...

I find it really hard to believe there are no engineering steel suppliers in the Philippines.

try Kim Ann engineering in Singapore i have bought stuff that isn't available in Australia from them...

try googling engineering steel supplier (insert your location here)

It will depend on the internal stresses of the sheet it is being cut out of, and how good the sheet is to start with. Water jet will give you less thermal distortion but laser is pretty good anyway...

I can see a potential problem with your plan, the laser cut finish on the sides of the spline may not be good enough for the plate to slide freely on the shaft and release properly, these plates...

I'm pretty skeptical it will hold that pressure as your effective wall thickness where the thread is is only 1.32mm, and you will also have mechanical forces acting on the ends of the cylinder.

I had a look at the 8’ one yesterday, it’s in fairly rough condition, there were a number of scratches and rust staining. It really needs refinishing before it can be used. The 2 short ones sold...

this one looks in ok condition, price is reasonable...

capstan / turret lathes run the same direction as normal lathes.

Auto screw machines and multispindles generally run in reverse, that is what those roller boxes would be off of

We aren't sure how it is wound yet but it is potted in bitumastic sealer, so we highly doubt we would be able to remove it intact enough to repair it. Its a pretty big job to get the chuck off and...

We have 200mm mitutoyo's at work and they are defiantly the best quantity caliper. also have some measuremax ones and the movement isn't as smooth, and the printing of the numbers aren't as crisp, we...

Done anyone on here know of any companies in Australia that can rewind large electromagents? We have a shorted segment on the dia 100" chuck on one of our grinders, we have asked around and been...

I would be interested in any collets you have for it

no need to doubt, really easy just call your local plate steel supplier, we get 2.4m X 6M sheets of 50,60,70 and 75mm plate at work regularly, Ferrocut keeps up to about 150mm thick here in Adelaide.

For those in SA, i use waterjet cutting services at Lonsdale (they do laser as well), have found them to have the best price and turn around in Adelaide. $250 is pretty steep for a minimum charge, a...

50 taper holders are pretty expensive, i would recommend a 50-40 reducer, that's what we use 75% of the time in our big manual mill at work.

You can use BT50 tools in a iso50 spindle, requires...

It is an early one but it is still a good price with those accessories. I would have gone for a road trip if i wasn't back at work.

Its also missing the overarm for the dividing head.

+1 for abrasifex or you will probably have a similar specialty abrasives supplier in your nearest capital city.

Springs aren't weldable. Find a spring maker and have a new leaf made

Sold

Not worth the messing around because you will also have the acid to dispose of.

Going to Commonwealth aircraft corporation by the looks of the marking on the crate. wonder if that lathe ended up getting painted light red:U

Pretty sure it is a type 5. We have a couple of those grinders at work i can check when i get back on the 8th. Pretty sure https://abrasiflex.com.au/product/grinding-wheels/ will have those wheels.

We got a 2ndhand one off mick moyles in sydney last year, they may still have some.

I may have a spare head i would sell but i don't have any spare chasers, i will have a look on the weekend.

I have a vague recollection of a running merlin sell for low $20K's at an auction i was at a while ago. the thing i do remember about that auction was there was a Meteor engine (tank version of the...

I had heaps of trouble with usb wifi dongles, i ended up getting a wifi card that plugs into the motherboard with an external antenna. got heaps better signal strength, speed and reliability.

Try and get a 2nd edition, the current black book is terrible and not worth the money.
