My Anest Iwata LPH-300 is supposed to require 200-240L/min according to the manual depending on the nozzle size in use.

In practice, I have had no problems with air supply spraying cabinetwork...

I am using a noisy Bunnings/SIP Eagle direct drive. Have boon looking for a quiet one.

Aldi had a portable Ferrrex Twin tank model for $300 guessing in the last 1-2 months - missed the catalog...

So there was daylight down the gap between the depression in the blade and the hump on the drum that locates the blade. Undoing the blade holder and making sure the blade was pushed in when...

>10 years later, it seems that nobody at Bosch cares enough to fix it. I got one cheap in a dented unopened box, so happy to play around. Considering replacing the drum with helical cutter drum like...

Track saw is easily accurate to 0.1mm. Depends what you measure with. Razor blade mark/stop method works well for one-offs. I use vernier stops on steel rules up to the back of the track for larger...

Not really that "interesting". Transformers are easy enough. Hz difference could cause a small speed reduction but that wouldn't badly affect a grinder. RS has UK site safety transformers that are...

for a cheaper possibly ok option, holzmann maschinen is austrian company with their own factories in china. with luck that means austrian design and quality standards now.

makita 9803 is still available in japan on amazon or rakuten. not cheap but looks amazing.

Whiteside from Holbren USA. I have 5mm solid carbide upcut spiral from them. Won't get it today though - about 2 weeks shipping by post. On current exchange rate. US40 is about the same as CarbiTool...

Got some premade tas oak panels from Masters. Boards are finger jointed sparsely but not on edges where they are butted if at all. Timber boards are 71x33mm making up panels 650x1200. I have joined...

I thought that's what the belt sander frames are for - make the sander a bit more "plane-like" evening the pressure on low spots and adding more on high spots and eliminating gouging with the toe. At...

Bugger. Someone must have filched the blades out of mine.

Saw one of these at a Bunnings bargain table for $99 - bashed about demo with no accessories. Online in Europe they are >100 euros or >100 UKP. They don't exist on AEG local website any more - so...

I saw last year the Makita small compound mitre saw is a lot cheaper than it used to be - now made in china and the quality or lack thereof is evident. So check carefully if looking at Makita.

How does one best shim a grinder spindle to get rid of play???

Or should we hammer the sides of the CBN wheel centre to downsize it?

If marking at manufacture is what happens, then the certification stamp applied locally can only be a "recertification". In which case some other mark must be a manufacture date.

But according to...

Technically, there appears to be no requirement for a manufacture date. My reading of the standard suggest all gas cylinders have to be certified in Australia by an Australian certified inspection...

Found a Standards Australia document called MP48-2008 "Certified Gas Cylinder Test Stations". As of 1/1/2003, the standard stamp of a test station is a little gas bottle on its side with a number in...

Help.

Perhaps you can post a photographic guide to figuring the age of the cylinder and making sense of old and new markings.

The only thing that is clear is a big stamp 2011, sprayed with...

Hmmm maybe. I got a SwapNGo green plastic skinned thinner metal BBQ gas cylinder.

A. they only fill to 8.5kg not 9.
B. the contract says I own the cylinder, but only they can fill it. Something...

I asked them all for details of their contracts, to see how sneaky they could be. The local welding shop quoted gas refills and said that BOC would send an invoice for "rental" whenever. Hard to know...

Don't forget about Stargas. I figured I was better off to start renting for less commitment and less possibility of getting stung for refills if I want to do more in the beginning. The rental is a...

Have looked at every deal I can find to date. But didn't know that anyone bought back gas bottles. That makes a difference to the high startup cost. But if I manage to keep a G size until after it...

The main problem with decanting is the high pressure involved and therefore the safety risk with a flexible high pressure connection. There are a couple of decant kits on the market. There is also...

I think it's worth complaining, though the likelihood of them doing something is probably proportional to the number of consumers out there. I complained about all the phone companies advertising...

Power10 gases and Speedgas have said there is no contract to sign, no condition, no terms. So from their perspective, they have sold us the cylinder and probably locked us in for life since nobody...

Power10 Gases do buy/swap australia wide (according to their web site) in D and E size. Can get from my local Total Tools, so no delivery fee (quoted $50). D size cylinder buy full $335, refill...

Good job! I think it's worth posting the method you used to debug and the actual component you needed to replace. One day, someone, somewhere will benefit from your experience, and at least one less...

Could it be too much acetone down the crack is not evaporating until heated???

TWI article on brass and bronze Welding of copper alloys - brasses and bronzes - Job knowledge 112

This is what I found in Australian Welding Institute document:

Cavities are often found...

EWM TIG primer has a chart on page 17 showing metals and electrode polarity. It says AC is best for brass, DCEN can be used.

Just curious. Learning stuff is fun. I figure if I learn new things thoroughly, then I can move on with confidence. The existence of "tricks of the trade" implies to me incomplete understanding. A...

Thanks for that - it was interesting written back in the 1980s when the author desrcibes arc physics being "too hard" for many.

Grahame, history is interesting...... (The Wright Brothers have been found recently not to have been the first.)

Turns out the research and images quoted by Miller on tip angle and penetration...

So here is what I found from my reading:
