Thread: Griptru wil not ad just
21/10/2020 07:13:08

I think my chuck looks like yours Steve, however I have not stripped it down to check, or clean. The chuck is probably as old as the lathe circa 1963.

However I treat it as a standard 3 jaw chuck and I dont bother with the griptru function. As long as I do all machining operations at the same time it's fine for me. If i need to rechuck a previous machined component i will use a independent 4 jaw and a "clock".....not sure if that's quicker than twiddling the adjusting screws on the the griptru or not......perhaps I should try!

The late great Tubal Cain who I have always regarded as one of my virtual mentors, said "there is always more than one solution to an engineering problem"....

66 days to chrimbo???? have ruined my day!!!!

Best wishes

Great to be able to put faces to names.

Well done Neil, for setting this up.

I will make sure I dont end up baby sitting 3 grandchildren under 6 next time and take a more active part at the next meeting!

The one that annoys me by far is...

Christmas stuff/tat appearing in shops in August

I also have the Grumpy T shirt

PS Every year when anyone in my family asks me what I would like for Christmas I always reply "metal - here is the list", the looks and comments that I get !

Thread: Engineering Sights on Google Streetview
04/10/2020 12:14:58

I got dragged by my better half last year to the Denby Pottery centre in Derbyshire, next to the car park I am think there were some remains of an engine but not sure. Next time I get dragged there I will take a photo.

Isn't there an old beam engine in the middle of a roundabout in Birmingham?

A great topic by the way!

Good to look at what you are doing with your Emco FB2......I will copy all of your modfications on to my FB2!

.....and thanks to Neil for the pdf

Thread: Steel stock for newbie ???
11/09/2020 08:32:04

This is a good example of why this forum is so good!

Btw it may be a good idea to introduce some sort of colour coding to the different types of steel that you intend to get, it can be difficult determining one type from another if they all get mixed up

As mine have........... (unhappy face)

Thread: Miracles do happen

Hi Dave,

I thought that cover picture was fantastic, so funny and very "seasonal"

I bought the mag just for the cover!!!!

Perhaps we ought to have a competition for the best Christmasy picture to go on the front of this years MEW?



Thread: Jobs we had as kids
08/09/2020 13:11:16

At 16 (1974) having left school and before I started my marine engineering apprenticeship I had a part time job in a carpet warehouse operating a flypress cutting the hole in the corner of carpet samples. The carpet samples were then collated in the right order and the hole through each was used to fasten them together.....

Thread: GHT crosslide micrometer collars for the myford S7
28/08/2020 07:39:20

Hi all,

I have been an admirer of George Thomas designs and have made many of the tools and equipment he described in the ME.

I am thinking of making this crosslide micrometer dial modification which he recommends, to my Myford Super 7 (non metric) circa 1962/3 lathe.

Has anyone carried out this modification? How did it go? Has it been useful and worthwhile?

Yes I know I could fit a DRO!.... but I would sooner blow the money on a DRO for the Emco mill.

Thread: Locktite
24/08/2020 11:49:38

Hi Jason,

How do you deal with the locked in stress after chain drilling out the crankshaft out of a piece of mild steel?

There are solutions such as use black hot rolled steel or normalise it, but just wondered if you have had issues in this area and if so what do you do to overcome it? I suppose a lot depends on the thickness of material and the size of the cut outs...



Thread: Any idea what this is guys & gals
24/08/2020 08:03:54

It does look like an air tool though, why not connect it to an air supply through a regulator and gradually increase the air pressure see what happens?


24/08/2020 06:55:29

I have no idea what it is either.

But I know that sometimes humour doesnt travel well occasionally.!

For a master class on this try looking on YouTube for "The Turbo Encabulator" ....I found it funny but my daughter did not ....she has a degree in history and doesnt understand "engineery things" and thought it was real .....some of the technical terminology used is wonderful and now a "ventilated grostling iron" can be added to my technical vocabulary!!!

Thread: Myford Mod
07/08/2020 07:50:20

I agree with Keith

GHT describes this also in the the ME in the mid 1970's. I have to say I have considered this upgrade on my Myford S7 (a kit of material and gears is available).

However it is a bit concerning to hear you mention this backlash. I guess it is the gearing modification inside the housing of the topslide....introducing this backlash due to the modification is not something I would consider a good thing.

However GHT in my view designed some very good kit and I would think that the backlash seen, may be due to inaccurate build by the maker not a design fault, but I stand to be corrected...

Hi Neil

I am considering entering the competition, with my meagre offering.

Hopefully there been a good response this year...



Thread: Old School Drawing Exercises and 2D CAD
25/07/2020 06:13:58

The dog ate my homework.....

Honestly this 3d drawing stuff you all post on here is fantastic.

I did a mechanical engineering apprenticeship in the 1970's and never got further than drawing spur gears in isometric projection with H2 pencils, set squares and other drawing instruments......

Thread: Emco FB2 Quirks and Additions
24/07/2020 13:26:34

Hello Graham,

I am also the owner of an Emco FB2, and it also has a tell tale oil leak, never thought it was due to positive pressure in the gearbox.

I laughed when I read your proof with a finger of a rubber glove though!

I would really appreciate a list of articles describing the modifications that you have done on your FB2.

Kind regards
