Yep, haven’t actually ordered It yet. Do you have a cheaper source?
Not too worried about the price as it will save me a lot of time and probably do a better job than hand carding.
There will still be places the carding wheel won’t be able to get to. For these I have a couple of Kingchrome soft SS wire brushes.

I went on line to order it from Brownwells but two things put me off pulling the buy trigger. The first was they don't keep them in stock and it has to come from the US. They say allow 21 days - HAH - I seriously doubt it.It takes 2-3 weeks just to get from Sydney to perth these days.
The second is you have to sign up to their ferkin email newsletter or you can't get past the buyer registration! This really gives me the pips and I have stopped buying from vendors that do that. I found one on US ebay for the same price and even though the shipping is "OUCH" I'm prepared to still buy it from them.

Hi Bob, Guys,
A trick that I use to get around their Email address collection scheme is I use a dummy address like,
"[email protected]" or "[email protected]". As long as it resolves to an apparently genuine address.
However I've also noticed that they have started to want to send you a receipt to your Email address. A lot of the local shops have started that trick ! I just say "what is wrong with giving me a receipt now". They can't legally refuse.Best Regards:
Baron J.

The fake email address doesn't work - they send an email to it and if it bounces they hold your order. When I tried this with one vendor I got an SMS asking me to provided a valid email address. What annoys me is that some vendors appear to be capturing details, including email addresses, as you type (not after you hit submit) and I'll start seeing targeted crap in facebook or on google. This happened to me a few months ago where I decided not to hit the submit button on my purchaser details form and a few days later ads for the goods appeared in my FB.

That sounds more like google to me(if you use any of their stuff)
For the emails you could use something like guerrillamail, its a one time email address, so if you are forced to reply to an email you can.

How thin is the oil?
Would a 650mm element do?

You'll have to work out sealing it though.

Thanks - thats worth knowing.
How does one then go for a subsequent purchase given account name is often email address and what if a dispute over purchased item?
How thin is the oil?
The oil does pick up some black oxide particles but this does not reduce its effectiveness and oil can be reused for this purpose many times.
The main purpose of the oil is to drive out residual water in tiny cracks etc. With the oil at 120ºC this turns the water to steam and drives it out and replaces the water in the crack with oil.

I might get one just ti play with it
Apart from a set of regular SS saucepans that I use for bluing small items, I generally use the same large container for the wash/rust conversion/oil bath steps. This means thoroughly washing out the container in between rtes steps - having an element in a trough or tube makes things even more difficult so I'm going to have a crack with the steam method. I
think I have worked out a way to do the oil bit, same as the cleaning and rusting method.
Drill hole in one end of steel rod and suspend vertically above a spill tray.
1) Cleaning - spray solvent on top of rod and let it run down the rod into a container, if grubby rub and reuse solvent from container.
wipe off solvent and then same thing with with Na2CO3 solution
Rinse with water.
2) Rusting: Spray (several times) with Salt/H2O2 solution and it rusts before your very eyes!!!!
3) Steam: suspend rod in vertical steam pipe.
4) repeat steps 3/4 until desired degree of bluing is achieved.
5) Oil: Suspend rod vertically again above spill tray and smaller heat proof container (baked bean can).
Heat oil in baked bean can to 130º
Heat rod with hot air gun.
Dribble hot oil over rod, repeat a few times using oil from heat proof container
Just realised the rod is solid MS so doesn't really need much oil treatment anyway.

The addresses last forever.(there are two addresses. One you use to check your inbox, the other is the address you give out)
The issue you might have is they say they only hold emails for 1 hour. I'm not sure how long they actual keep them as I haven't used this for a few years. I doubt its what would called "secure", just really large numbers stopping someone reading your mail. so I would change the email once you start shopping. Having your own domain is handy for this sort of thing.

Hi Bob, Guys,
This is all about data collection ! I agree with Stuart, Google is the prime suspect though just about every site that you interact with has started the verification trick. Having your own domain means that you can generate as many dummy addresses as you like and then track where they have gone to and come from. I just black hole them unless its something I want.
You can also add unwanted domains to your hosts file and black hole them that way Though some web sites, this one included won't let you interact completely if you block certain items. Which is understandable that they don't want you blocking their advertisers.Best Regards:

Steam power
I decided to followup on using steam instead of hot water for the long object I'm trying to blue.
I do have a piece of solid PVC pipe similar to what the fella in the Youtube video uses - standard Stormwater and DWV pipe of which I have heaps is usually foam core which is not as good, apparently - but the solid PVC pipe was 1.8m long and I did not want to cut it unless I really had to so I thought I would have a go with a length of 1.2m x 75mm Zincalume downpipe.
Steampower.jpg
I cut out a lid from a piece scrap 2mm Al to fit a 5L SS copper bottom saucepan and used a 75 mm ZnAl downpipes flange (~$3 at bunnings) to connect the lid to the pipe. The saucepan then sit in an electric frypan.
2 cups of water in the saucepan, it gets hot and makes steam really quickly.
Initially I thought the pipe would not get hot enough so I would have to insulate it ( I even dragged a garbage bag of fibreglass insulation out from under the house) but it was not needed as it works without insulation.
Without the cap (the SS lid from a broken coffee percolator that has been hanging around my shed for about 5 years) on top the steam (well, it's really water vapour) temp is around 80º but with the lid on it reaches 93ºC and this is enough to make the red oxide black.
A side benefit is the steam condenses on th inside of the pipe or on the workpiece and then drips back into the sauce pan so the water in the saucepan can be reused over and over as its only the steam than rises up into the pipe to interact with the red rusted workpiece. When boiling teh workpiece in water the water should be replaced every time this step is done.
Thanks Jack.

I did come very close several times to throwing it.
BTW after going under the house to drag out the insulation that I didn't use I also spied a tall rectangular SS water tank from a caravan I stuck under there about 5 years ago. The tank was given to me by a mate who had his tank replaced under warranty and he was just going to put the old tank on the verge. Lucky I didn't see it earlier as I would have been temped to cut 1/3 of a side off to make a long trough. I think the steam chimney idea is much neater.
