Thread: Myford headstock bearing replacement
24/11/2016 07:45:47
Posted by andy may 1 on 23/11/2016 22:38:28:

Me again, more questions….

Could someone take a photo of their bronze bush (oo-er) and spindle at the front so i can see if the relative positions look anything like mine? I'm wondering if the bronze bush is still too far forward somehow.

cheers
Andy

No photo at the moment but a few dimensions from my Mk1 S7 if they help,

There is 5mm of bronze bush sticking out of the front of the headstock casting, this is +/- 0.1 as I'm measuring to a cast face,

the ϕ43.8 steel shoulder on the spindle is sticking out 2.5mm and when a chuck is screwed on there is 7mm between the back face of the chuck and the headstock casting, this is slightly smaller than 5mm + 2.5mm due to a shallow machined recess on the chuck back face.

Of course I can't guarantee that these are the dimensions when it left Myfords, someone might have changed the bearing before I got it.

Thread: LED "Fluorescent" tubes...

Aldi have a '5W COB LED' worklight, branded LIGHTWAY

on sale today, at £4.99 with three AA batteries [sic]

... It also has a single Cree LED torch.

Question: How long will three AA cells last, on a current draw of > 1Amp ?

[or is it all spec-man-ship ?]

I bought a single Cree LED torch from Lidl a couple of weeks ago, it's rated at 10W, 600 lumens, it's incredibly bright with a better beam than my cars headlights and these are Osram Night Breaker Plus halogen bulbs, the torch has 3 'C' cells giving 4.5V so that's over 2 amps drain. The instructions say battery life is 3 hours, I will be very surprised and very pleased if they last that long.

These fit the Myford toolpost which I notice are out of stock at the moment.

I hope this helps

I must have got the last two from your link, excellent quality and very quick deilvery.

Freeview is unreliable around this area even though I am less than 5 K from the masts at Bluebell hill in Medway. I am not allowed festoon type ariels on the roof.

But can't you use your existing Sky dish with a Freesat box?

I have Sky myself for broadband, TV and the telephone and I'm reasonably happy with them.

Thread: Lathe Rear Tool Post For Parting Off
21/10/2016 19:39:42
Posted by not done it yet on 21/10/2016 19:16:23:

stated the biggest He did was 18".

Any idea of the width of his parting off tool?

 

Would it need to be very wide if you did it in stages? I admit my experience of parting off large diameters is nil, 18" won't fit on the Myford but even with something like 1" dia I start with only a short length, say 1/4" of the 1/16" wide tool blade sticking out of the holder and then withdraw the tool and then extend it, then the tool which is very strong vertically is constrained by the groove sides to stop it flexing sideways,  I would repeat the process depending on how large the bar is to ensure only a short length of blade is unsupported, or am I being too cautious?

it's now running W10 Home version 1511 and although I have used it quite a bit recently as far as I am aware I have never had any updates at all.

I'm on 1607... do you have an internet connection?

Neil

Yes it's always used on the internet, I only use it for going on the WWW, there's nothing I do with it that's off line at all.

John

'twas a jest - you have to be online to use the forum!

I must have been half asleep, so obvious when pointed out, it's started today off well with a laugh though.

I don't think Microsoft can like me as they never seem to send me anything, I use Linux for 99% of my tasks but bought a Dell laptop to run my Garmin software etc and to use away from home, I bought it second hand from a computer shop with W7 on, but as I had never used anything newer than XP I upgraded it to W10 last May when it was free, it's now running W10 Home version 1511 and although I have used it quite a bit recently as far as I am aware I have never had any updates at all.

A sock puppet is where a poster has two accounts. Usually done to reply to ones own posts or support ones own issues.
Usually the sign of an overactive ego.

Thanks John,

It's not just engineering techniques that one learns on here.

I might as well ask, what is a "sock puppet", I've never heard the expression and a quick look on Google only gave me a pageful of sites telling me how to make Sesame Street lookalikes.

A quick look on the RS Comps' website and they are shown as 1/4" - 36 NUEF, which I am assuming means National Unified Extra Fine?

The ISO 150 grade is equivalent to SAE 90 gear oil, or straight 40 weight engine oil. Nothing exotic.

And Halfords sell it in 1L bottles for £9.99, Comma Gear Oil EP80W90 GL5.

Thread: Diesel in a paraffin blow lamp?
11/09/2016 12:04:12
Posted by Ajohnw on 10/09/2016 17:12:52:

It seems that paraffin can be mixed in with diesel. Older diesels will run on paraffin but I doubt if the modern engines will tolerate it due to far more sophisticated engine management.

About 20 years ago I had a Ford Fiesta 1.6 diesel and the handbook suggested that in very cold weather to reduce the chance of fuel waxing that paraffin could be added, it gave a ratio that I can't remember, there was also a warning that this could be illegal in certain countries.

Thread: Things to save from a CRT TV being scrapped

All of which will never get used and turn what could be a nice working area into a tip

I agree with John on this, amongst my many interests I am a radio amateur and have built quite a few bits and pieces over the years, about 10 years ago I dismantled a Sony 32" CRT TV looking for useful items, however the only things I found that could be useful were 2 loudspeakers which I kept until about 6 months ago and then binned them having moved them around countless times as they were always in the way.

The most rewarding part of the exercise was dropping the bare tube about 10' onto the concrete floor at the local tip.

I wouldn't have thought it was worth doing anything with them except scrapping them, you can buy brand new ones in Wilko's for 80p.

To be fair I have a blow lamp than runs on petrol and some do run on alchohol.

A chap I knew about 40 years ago did some plumbing work for me and he used a petrol blowlamp and he was adamant that only 4 star petrol should be used in it, he said it wouldn't work as well on any other grade, perhaps he'd had the compression ratio increased?

When sorting out the results of petroleum refining, cracking etc, the stuff that is less volatile than petrol is divided into two lots. The stuff which smells less and is mainly straight-chain or 'aliphatic' molecules goes to make paraffin, the stuff which is in rings of atoms and is called 'aromatic' goes as diesel. So, while diesel will work in a paraffin lamp, it will smoke and smell. And paraffin will work in a diesel but not so well.

Cheers, Tim

That's cleared up something that I've wanted to know for a while, I have a sailing boat with a diesel engine and it has a Taylors paraffin cooker in the cabin, often I've wondered if I could use diesel for both, I'll carry on using separate fuels.

@ Sandgrounder,

I was logged in when I rang up.

That is presumably why they asked for the six digit number, if you ring up again without logging in you should get through.

@ Sandgrounder,

When I ring the free number, I'm asked for a six digit number, from where?

Just tried the 0800 number again now my six digit number has lapsed, I'm asked 'I see you are calling from xxxxxxxxxx' shall I use that number to reference ( or something like that ) your PayPal account? I then hung up, were you logged in when you rang up?
