Thread: UK DRIVING LICENCE [ 2022 issue ]
29/04/2022 08:45:43

Just a note for anyone who still has a pre-2000 paper licence, it's only legal if all the details are still accurate.

This would have made a great article for MEW... 😁

Keep everything in it's own special place for that feeling of satisfaction on the rare occasions when something is where you expect it to be.

Big difference between a mandrill and a mandrel devil

Welcome to the forum, Jon.

Thread: Myford ML7 1950 vintage
04/09/2020 19:06:22

Welcome Stefan,

My recollection is that such handwheel repairs have been covered in ME and MEW a few times over the years, cutting square threads certainly has, although it sounds like you have a strategy to address the problem.

Thread: Logging in to MyBT
04/09/2020 18:59:33

I recently had an email from TalkTalk telling me they were going to put my monthly DD up, so they could continue to supply me with fast reliable broadband.

As their broadband is neither fast nor reliable* I requested a call back several days ago.

So far - zilch.

Neil

*To be fair, this is more down to BT Openreach than TalkTalk.

Thread: New computer possibly required
01/02/2020 09:16:10

Hi Peter,

Look at HP's own website.

I bought an excellent laptop for work with an SSD direct from them, cost was reasonable (£30 more than an the previous model which was being sold off cheap at Currys) and it came without the 'bloatware' you get on most computers, It had USB3 and 3.1 and is very fast. Screen is good too.

Only bad thing was having to uninstall Macafee before it could ruin everything, and activate Windows Defender instead.

Neil

Downside is I now want a desktop that runs as fast!

Thread: How to maximise material removal rate on a mini lathe?
01/06/2018 19:57:09

I think the question was rhetorical? Rainbows seems to have demonstrated just how much you can hack off with a mini lathe.

(Not often I see a lathe in more of a mess than mine)

Only comments, CCMT best for that sort of abuse, the geometry is stronger and will blunt less rapidly - it also heats the steel which makes cutting easier - if the feedrate is OK. Don't forget to speed up as the diameter drops.

CCGT better for finishing.

With CCMT in particular you need to make sure that as much as possible, if not all, of the corner radius is in the cut.

Took a 3-4mm deep cut in medium carbon steel on the SC4 for the last lathework series episode with a CCMT insert and it left a satin finish on steel that tends to look like a ploughed field.

CCGT are ground to sharp edges so you can more easily get away with the light cuts and lower speeds usually used with HSS.

The mechanics of a mini-lathe can easily cope with 3mm cuts in mild steel, but whether or not the electrics can depends on the types of motor, quality of control board tool, quality of tool and experience of user...

Toolpost angle should be chosen to present the tool edge as well as possible while avoiding any risk of hitting those nasty whirly jaw-bits.

Thread: best machine tools for lathe

There's a good article in another place

Glad to hear it, Neil yes

Note: I did, cautiously, use the phrase "It looks like" ... [which it still does]

MichaelG.

If it was my old set, you would probably have been right..

I'm not paying for a copy of DIN4980 to find out exactly what the specification is. I note that while some beautifully finished brazed tip tooling costs more than the typical set used by hobbyists, some 'professional supplies' sites sell supposedly 'precision ground' DIN4980 tools that have the entire carbide tip completely covered in paint...

Thread: Myford chuck 'oiling point'
25/01/2018 09:21:07

The oil needs to be fluid enough to spread through the chuck from the oiling point.

If it's a flame cut blank the edges may be partially hardened, it's possible to grind off the skin.

Thanks, sorted now - I thought I had already sorted it but must have got them muddled.

Just in case anyone wants to build the 'Improved Nakamura' QCTP toolpost design and can't access the back issues of MEW, there's a description of how to make it and a set of toolholders and a download of the plans HERE
