Mmm... some thoughts on alternative rust removers:

Evaporust costs about €50 for 5 L here, it consists of < 16% chelating agent ( the exact type is a well guarded secret), <1% detergent and the rest is water.

Citric acid is frequently suggested as a chelating agent but it will chelate (make soluble) iron as well as iron oxides so you shouldn't leave iron in it too long.

A good chelating agent for iron oxides is oxalic acid which costs about €8 for 1 kg on line in powder form, more than enough for 5 L of rust remover just add a few drops of washing up liquid as a wetting agent and you should have a good rust remover.

As for vinegar, I'd save it for my chips. It is not a chelating agent, the acetic acid it contains will make ferric acetate with rust and that is only moderately soluble in water.

Oxalic acid is a relatively mild poison but I wouldn't drink it. It is used as an antidote to lead poisoning.

Thread: At It Again - But New Twist? (Scammers)

My wife had one on Friday from an old lady she knows in the WI, she asked if we used Amazon, my wife said yes and then the lady asked if she could buy her a $200 gift voucher as her computer would not work properly. My wife said " who is going to America? and the reply came back " don't know yet"

I told the wife to do nothing as it was very suspicious, and I checked the email was not masked but it was the ladies proper email. On Saturday an email came from the local WI president saying to be aware of an Amazon scam and that the old lady had confirmed she had no idea what was going on with her email.

The old lady needs to change her password to her email account.

Do their predators see in monochrome or colour? It would be interesting to repeat the experiment using a camera with the same spectral sensitivity as the predators.

I've been getting demands for renewal by international mail weeks after renewing online. If Mortons got their systems in order perhaps they could reduce our subscriptions!

Thread: Google to cease suport for 32bit.

It seems that, for now, it will only affect you if you use Google Drive for cloud storage on a 32 bit version of Windows, an old 32 bit Android device, or a 32 bit Linux system.

This little Windows program might help:

You just have to enter your leadscrew pitch and list all the change wheels you have and it will come up with a few suggested setups.

I have found notes that say I used 3/8" od x 1" long with 0.064" wire. Can't remember if I had to modify them at all.

Weren't the screws fixing UK power outlets and light switches to the wall box 3 BA?

Russell

No, they were 4BA. and now they are 3.5mm.

Peter

Well, perhaps they changed from 3 BA to 4 BA later but I am sure they were 3 BA when I worked for an electrical and and electronics shop in about 1960 to 1962.

I was apprenticed at one of the largest electrical manufacturers in the country. BA threads were always even numbers.

O.K. Russell … Someone has to ask, so it might as well be me !

What is the idea behind having two sets of jaws ?

I have always wondered that. I have no idea!

I guess the handle will have a threaded portion so that when rotated it will draw the part on the left in.

Russell

Here's one I found locally (in France):

Talking of improperly using inserts, the non-ferrous type sold by Arc Euro work well on steel at hobby machine RPM. It's to do with their shape and sharpness.

Dave

Agreed. They are particularly good for small diameter work.

Thread: er 32 collets

I had a senior moment! ER32 collets are 1mm, not 2mm range.

Apologies for the confusion.

Dave

Don't worry Dave. I have lots of them now.

That ER32 have a 2mm clamp range is highly convenient on unusual occasions, but using the full range is extra work, annoying if it has to be done a lot.

Dave

That's interesting. My ER32 collets are all marked as having a 1 mm range. Is the greater range a new innovation? I have never had any problems using them on imperial size cutters within that range.

Beautiful, both the models and the full size version. Much prettier than my (regretfully sold) 1927/1934 Austin Seven special. I would be ashamed to put a picture of it here by comparison but you can see one in my album.

Welcome, Ross, your woodworking skills will stand you in good stead, machining metal is much the same basically.

Yes, except that metals don't have a habit of splitting along the grain.

P.S Don't ask me about cannons and bombs made with a certain garden substance and sugar, I know nothing.

How about the explosive made from iodine crystals and (censored). Extremely sensitive when dry. Used to be put under the lifting flap of school desks.

One of the advantages of Freecad is that a Linux version is available. I would agree that its learning curve is steep but it is very comprehensive.
