Dave..............."Rarely turns out well when people act on duff information"........are we still on the topic of computers? or has the thread accidently moved to erm,..... a more topical subject !!!

I once had an Oric 1, typed in reams of Basic commands from magazines then spent the rest of the day debugging it, until my Mum pulls out the mains lead and all was lost......

Not sure I have enough time in the day to play about with Raspberry's or Ardunio's now but it does look a fun thing to play with when the workshop is too cold....

Hi Neil

Count me in

I am sure the late great Tubal Cain aka T D Walshaw, made a case described in the ME years ago of converting his wide guide Myford to narrow guide...

Cannot recall the rational for this, but I will try and find the article

PS "waxing a dirt floor"......I like that!!!

Very interesting results, and great use of a spreadsheet to show what is happening with the wear on your lathe bed.

I have a myford super 7 circa 1962/3 and I will check mine in the same way as you did.

I will leave it to others with more knowledge than me regarding wear on machine tools but it does seem to agree with your conclusions that much of the wear is on the front of the front shear which suggests that conversion to wide guide will not have much affect...

The middle two graphs at the tailstock end do seem to confirm this is due to the tailstock as it uses the middle two shears for guidance.

Not sure what the myford tolerances are but since we are looking at 1 or 2 thou over 24 inches in the worse case is this acceptable for a myford?....I am not sure...

Over to the other boys and girls of the forum....

Hi

I am almost at the end of the modifications to my Myford super 7 crosslide as per the design by George Thomas. I fitted two sets of needle bearings etc as per the design.

I will try and post some pics soon.

When I had to modify the crosslide bracket I had to mount it on the faceplate and then having no crosslide function, I swung the topslide through 90 and used that as the crosslide. It went ok, but I was extra careful as didnt have a spare bracket if it all happened to end in disaster!

So far it's looking to be a fantastic upgrade to the old super 7 crosslide.

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????......you have ruined my day!!!!

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!

Derek

Great job! Like the videos.....you have got "the" bug now !

Next job to make a boiler and run it on steam...

Well done I have been following the build log and the care that you took in making the engine has paid off.

Kind regards

Derek

It's a yes from me ....

Kind regards

Derek

I would like to take part, so count me in...

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 !

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!

Thanks Graham,

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

Derek

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)

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?

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.....

Thanks to both of you for stepping up to the lofty heights of moderator!

Hopefully we will all behave ourselves...

By the way who moderates the moderators?......!

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.

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...

Derek

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?
