We have upgraded

[William SParticipant @williams]

Hello all, I wasn't kidding when I said the shed was going to evolve. So the seig sc2 lathe (our first real lathe) has been a fantastic beginners machine to learn on, however there's always been the underlying problems with it. Our dream has always been to own a super 7, This dream was completed last Saturday and it hasn't really broken the bank. So about a month and half ago there was a super 7 on gumtree (fleabays blocked at school) It was £2,500 and it came with quite a few bits, then I found the same one on fleabay. both these adverts then were removed, we were a bit peeved because it was in Portsmouth and we were going down there the following weekend, well fast forward to 2/3 ago it reappeared at a lower price of £1,800, contact was made with the seller and he said if we paid the deposit it was ours. Then arrangements were made to collect it last Saturday, which we dually did, we hired a transit for just the ease and we didn't really know how much there was with it and 3 people going would've been difficult in a 02 plate golf estate. left home at 5:30am and drove to Portsmouth, arrived at 7:40 in the morning, pretty good going. told him we would arrive at around 8:00, saw the lathe and was extremely pleased to see that it was practically mint no wear at all. It was his late grandfather's and the seller had had it since 2010 and never really used it. So we took the lathe off the cabinet and put it on the large trolly we had taken with us, then bolted wooden bearers to the mounting holes so that it wouldn't tip and would give a handle to hold. wheeled it over to the van and lifted it in strapped it to the bulkhead. And loaded everything around it. Left his place at 10:10 to drive back home encountered a slight bit of traffic on the M25. It was worst on the A21 Any way arrived home at 1:20 unloaded the van cleared a space in the shed. pillar drill and belt sander have temporarily been relegated to the end shed. Put it back together and went for a Chinese with my dads mum. Quite a busy day when compared to a normal Saturday.

Well here's the lathe in pictures:

The serial number is a 73/74 model so not terrifically old or too young

Its got a 3 phase inverter so variable speed is fantastic.

3 chucks it came with

Both the 3 and 4 jaw burned chucks have this written on them,is this normal?

And a nice set of collets. Questions to follow!

Turret

Taper turning attachment.

Assorted bits and pieces

Can anybody tell me what type the above collets are. I'll get better images tomorrow

we also got both steady's, tilting vertical slide, faceplate, angle plate, full coolant pump and a small rotary table, so we are pretty set up straight away I think there is a few parts from an ml7 (30 and 75 tooth change wheels, carriage hand wheel gears,etc)

Everything has been disassembled, cleaned and regreased/oiled by me over the past week and works as it should, its now finding the projects to actually use most of the stuff (the turret may come in useful)

There will be a few more questions to follow so any help will be greatly appreciated.

Thanks again

William

From a Seig to a Myford

[RobboParticipant @robbo]

The collets in picture 12 look like the Boxford size from Crawford. Forget the number just now. Also the vertical slide just peeping into the picture and also in pic 9 looks like a Boxford one.

Looks like you got a great buy, in great condition.

The capstan fixture is an expensive extra on its own!

Boxford collets are 3C and go up to 1/2 inch. They use an adaptor that fits a MT3 spindle.

[HopperParticipant @hopper]

Good score! It certainly looks like a minter. And nice pile of accessories to go with it too. The cross slide turret is a not-so-common one and looks pretty handy if doing repetition work. Have fun!

[Thor 🇳🇴Participant @thor]

Congratulations William, that lathe looks to be in mint condition and with a lot of accessories.

Hi William; boy have you hit the Model Eng. jackpot with that purchase, well done that man! I have that green eyed monster on my shoulders today…

[Neil WyattModerator @neilwyatt]

Looks like a good deal from here!

Will you be letting your dad have a go?

[Howard LewisParticipant @howardlewis46836]

Looks like you have got a real bargain! Clutch, Norton Box Capstan, and three chucks!

You have YEARS of fun ahead of you. (If only making adaptors for the various non Myford accessories, (Either that or they will partially fund the Myford bits that you do want)

No doubt there are some readers who are green with envy

Hi all and thanks for the comments

Thank you for the information on the Boxford 3c collets, as you can probably guess it doesn't fit the Myford.The seller did have a Colchester student as well, would it fit that? At least I now know the name of them.

It's the Myford top slide in the background of image 9, it's upside down so it doesn't pick up the swarf off the bench!

Both the burned 3 and 4 jaw chucks have this written on them, Is this normal for ML7 chucks.

There was a few bits with the lathe that we think are for an ML7.The 75 and 30 tooth change gears we don't think are for the super 7, there is also the gears for the carriage handwheel, the vertical slide and turret are both a more greener grey and swarf has been squashed into the mounting holes that don't appear to line up with the super 7's cross slide on the turret (am I right in thinking the ML7 has a different cross slide?)

I think the taper turning attachment is a Hemingway kit, can anybody tell me what parts are missing?

Does anybody know the name of the above collets? they are 1" in diameter and 1 3/4" long. the holder is about 3" long and 2 1/4" wide and screws directly onto the spindle nose.

here's the first item I made on the lathe, well I made 4 of them. bushes to stop the screws rattling about. They were made entirely on the Myford including chamfering the back to clear the welds which was done with the vertical slide. it was a joy to use and I look forward to working on the machine more. We have since bolted it all down and levelled it all in.

Finally I would like a bit of advice on the oils people use and what is the best oiler for the nipples on the machine.

Many thanks William

(p.s my dad will get the chance to use it one day!)

[Rik ShawParticipant @rikshaw]

Some lovely kit there William, congrats on finding a beaut at a good price. Oil? Some people are very fussy but I use any motor oil I can lay my hands on from the Sunday boot as long as its no more than £2 for five litres.

[fivethou hammerParticipant @fivethouhammer12006]

Great piece of kit William.

Very good price too. The add-ons are near what you paid for the whole lot. That machine will keep you occupied for a few decades.

E-Bay can indeed be blindingly good at times. The world's your lobster with that outfit.

Best wishes

Hi William

Yes the standard 3 jaw chuck for my S7 has "Made for Myford " on it.

Good luck with it I'm sure you will enjoy it and it will,teach you a lot

There is a comment earlier in this thread about whether there are any bits missing from the taper turning attachment.

I can't see the female part of the dovetail slide. This is carried on the adjustable slide which I believe mounts to the back of the lathe bed, carried on a big cast iron bracket. Or at least that's how the Myford one mounts.

This is what the Myford own brand version looks like. The nut and two dowels line up with the rearmost slot on the cross slide. Take out the cross slide screw, and the motion of the cross slide is now controlled by the dovetail slider.

You've got the long slotted piece, this bolts to the cross slide. But I don't see anything that marries to the dovetail piece unless the long slotted bit has got a dove tail machined in the underside?

Not familiar with this version of the taper turning attachment, but there does seem to be something missing?
