Thread: Seeking someone to make a component (spacer)

why is it when you own a machine people always want you to make something for nothing

I would suggest you go back and read the chap's post Paul. He is not asking for them to be done for nothing, he is offering to pay and frankly £12 (plus a bit - little bit- of postage) works out at about £23 an hour if you dither. Material cost is about a pound. Doesn't sound like nothing to me. (oh, and 6p for the jiffy bag).

I don't work for nothing but little jobs like this put a bit of cash in the slush fund and I usually use it to buy tooling. Works out fine to be honest.

"Nylon absorbing moisture" - Really? It is that Mission Critical we are even going to consider this? Give me a break. It isn't worth considering and if we are going to consider electrocution, again, really? We have an earth I take it?

Hi Richard,

Just a hint but I think you may need to consider the cost of 1" nylon rod...

**LINK**

Even in God's Own County it's not that cheap.

Jon

You need to buy plastic from a plastics supplier: LINK Works out at three quid for half a metre. Buy £50 and it's free shipping or I just collect as I am going past.

Thread: TIG welding

That frame IS a work of art. I see stuff like this and wonder why I bother sometimes, but then it gives me something to aspire to.

Not that I will ever as I just don't get the "practice" in that someone doing it every day does. Very impressive.

Superb. There is nothing to substitute that feeling of accomplishment when you have built something yourself and it actually works well. I sympathise with you over the scrapping of a perfectly serviceable part. I did something similar recently and you just want to bang your head off the wall.

Thread: Dropped a clanger
05/05/2015 16:50:55

What can I tell you, faster than a fast thing and Shaun, you are a Gent.

Muzzer, not only did I lose the manual, but forgot where I had bought it BUT as with all things financial I distinctly remember paying £100 for it.

I bought it for a Hydrovane compressor but subsequently discovered that it would not work as the windings were well and truly buried then to my dismay I discovered it needed new vanes and was long out of production

On the bright side I am going to use it on my new lathe No, there is nothing wrong with the current setup and it is working perfectly but until you have experienced a 3 phase motor with a VFD you cannot begin to understand the transformation this brings about in any machine. Plus, I can stuff a big motor on it, you cannot beat big horsepower

and lost the Bl**dy manual! Oh the grief I can cause myself. I bought this sometime last year, brand new boxed VFD. I HAD the manual, because I was reading it, but nowhere to be seen and God knows I have looked.

If some kind soul could help me out and try to identify what/make/brand/generic it is I would be extremely grateful. And just to confirm everyone's suspicions, I have forgotten where I bought it too......

Thread: What did you do today (2015)
04/05/2015 19:32:46

Went over to collect a rifle action from a chap. He had bought it just for some of the parts so I can build him a rifle, he went to pick it up and it was all wrapped up for him. He used some very interesting language as he described variously the person who had owned it and the person who had "modified" it.
I must confess I was at a bit of a loss myself.

Thread: How to make an arc furnace?
30/04/2015 22:31:04

I wish you wouldn't do this, you will get me started off on my Induction Furnace ideas again. Last time I planned it out I calculated 160 foot of armoured cable because I suspect I need the current from two lamp posts, not just one. wink 2

Why 5C? Why not an ER40 (for instance)?
Just interested in your reasoning.

Thread: Indexable tips and their use
30/04/2015 19:48:43

The Milling tips are SNMM 090308 EL and the Turning tips are TNEG 2521 so if anyone can proffer any clues as to what they are or the breakdown of the nomenclature I would be extremely grateful.

I blame bloody Rik anyway because his post about making tooling for the tips started the brain worm going - I knew I had a good couple of boxes stashed somewherefrown

graham.

30/04/2015 19:29:15

Well, I am also having a bit of an adventure, but with Indexable Milling cutters. It's given me a headache to be honest. I am also building a couple of toolholders as I have found a couple of boxes of "Valenite" brand turning tips and if I didn't know better, I would say they are Imperial. The tips are from Canada so could well be. Anyway, I will never get a toolholder for them and I have sufficient to make it worthwhile making tooling.

Danny, thanks for that I love quotes and collect them (sad or what) and this is one of my favourites:

“Man surprised me most about humanity. Because he sacrifices his health in order to make money.Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived.”........Dalai Lama

Which can be summed up: "All men die, few truly live."

Well I asked my girlfriend to show a couple of examples of her welding but she's too shy so I'll do it for her.

Bet she's hellish knitting an Aran Sweater!

On another note, interesting that quite a lot of people here are knowledgeable about the dangers of Tungsten. The government are actually considering replacing lead shot with Tungsten Matrix. (or they were, maybe someone has passed them a note by now).

I'll be making my second visit. I was pretty awestruck last year, spent too much time gawping and not really looking. Was also really surprised by the focused and competitve buying abilities demonstrated by many attendees - are these really the same people who potter about dutifully following their better halves found Sainsbury's on a Saturday afternoon?

I find an Umbrella useful!

Thread: What did you do today (2015)

Went on the hunt for a 4MT to Myford adaptor and discovered there were none so nipped into one of my favourite tool shops and bought this:

mt4 cutter.jpg

Perfect, threaded for a drawbar too. Going to cut the end off, weld something decent to it and cut a thread.
God knows how much it must have cost but I gave a fiver for it.

As an aside, if anyone wants the two parting off tool holders shown in the pic, PM me your address and I will put them in the post for you.

Thread: Woodruff keys
27/04/2015 19:55:29
Posted by roy entwistle on 27/04/2015 18:12:06:

Who on earth buys woodruff keys ?

There are two clear sides to this comment and I see both quite clearly. If you are retired or at least a model engineer (or any sort of maker/doer) I can see the sense in someone wanting to make one. Even if it is just to experience this.

On the other side of the coin, I just would not have the time or inclination, I would pull the box out marked "Woodruff Keys" and select one, modifying it if need be. Anyone trying to earn a crust just doesn't have the time.

There is a third option - you are on a breakdown and you can either wait for the shops to open tomorrow or actually get paid for making one, that works for me too. I have done more than my share of all nighters. And a couple of All Weekenders too.

Thread: Estimated selling price of a Myford VMB mill?

Posted by John Haine on 27/04/2015 08:41:09:

It's worth what someone will pay. You need to get it in front of as many people as possible and see what they bid, so eBay is your friend. There was one recently that went for over a grand IIRC, and that was one the seller had taken the motor off for some unaccountable reason.

A friend of mine was buying a gun recently but the seller wanted to keep the front sight. Which was of absolutely no use to anyone except the owner of that particular make and model of gun, sans front sight.

go figure!
