After the scrapping of the big TOS I was left with what looked like a WWII battlefield.

From this.

to this.

http://www.stevenson-engineers.co.uk/files/dday10.jpg


And at the end of yesterday after a full days cutting chopping and welding we are now here.

http://img.photobucket.com/albums/0903/registered_user/dday16.jpg

Still looks a mess and a lot of what's strewn around is due to go into the new bench or sold on.

Bench is 12' long with 5 large tins in runners at the far end to hold useful short ends of steel, alloy and brass.

Two new 7 drawer cabinets from Machine mart for inserts and other small tooling, that will get rid of the cupboard above and I'll get the wall painted.

Two shelves this end to hold the nearly obsolete toolboxes from the truck garage.
Next to that at the top will be a pull out drawer to hold the small CNC engraving machine as it only needs access to change the plate being engraved, no need to take up valuable worktop real estate.

Below that and next to it are cupboards. Ordered two big 10' x 5' MDF sheets for the worktop, shelves and door fronts.
Get nephew to cut these out as he has a kitchen and bathroom business and has a CNC saw which works all the cuts out and saws very accurately.

Aim is to get 3 or 4 small CNC's on the top for small production work.

Unfortunately work keeps getting in the way and it's liable to be a bit protracted in getting done but it's getting better all the while.

The good news is you still have enough swarf on the floor that if sold for scrap would pay off the the queen's jubilee bill.

I don't recognize that planar feature below your broom - seems to cover most of the shop. Is that a floor? :D

Are you working to a formula John? Such as 'scrap everything that hasn't been used in the last 3 years'?

I do that sometimes, though on a much smaller scale of course :)

John Stevenson
06-17-2012, 11:17 AM
No it's not as bad as it sounds.
Lathe obviously went for scrap, slotter was sold on for a decent price to a good home as I now have a slotting head for the Bridgy and my slotting work is capable of being done on this.

Much of what else has gone for scrap are jig and fixtures for jobs or customers long gone. A fair amount of short bar ends have also gone for scrap as the boxes haven't been touched in years. Having said that there are still loads of bar ends left that I hope will get used.

Some is just plain rubbish and turnings from behind things, the mini skip is quite full, hopefully it gets emptied this coming week.

Some stuff should have not been saved in the first place, things like big lathe tools with damaged seats for inserts, too big to use and not worth repairing anyway, pure weight of scrap metal.

Found two revolving centres with MT7, yes SEVEN, no typo, shanks.
WTF takes those ??
Toss up whether to list on Ebay or just bite the bullet.

Thing is I know 80% of what's there but also know I'll never use it.

Take these drives for instance.

Many years ago I used to make these for the racing bikes.
Just found 20 bronze castings, un-machined, part of the 20% I don't know I have ;)

Do I save them for another 20 years ?
Do I try to sell them as bare castings ?
Or do I weigh them in as scrap price of bronze is probably worth more that their resale value ?

My woodshop is just as bad at the moment . I have newly bought timber everywhere and can hardly move.Like your machine shop John it will all look good on the day.
I am always tinkerring with my shop design and am always changing things as I get new machinery or wood. this time I am clearing thining machinery were I have doubles and sorting out what I have made a real mess your shop will be great when finished too was it difficult to let go of the TOS lathe? I suppose you become attached after a while. ? Alistair

John Stevenson

was it difficult to let go of the TOS lathe? I suppose you become attached after a while. ? Alistair

In the case of the TOS, not it wasn't hard, just very relieved to be rid of it.

The problem was the lathe attracted the wrong sort of work. It could handle 2 metres between centres, that's about 84" and because of this I was getting jobs that had to be craned into the machine, turned undersize, craned out, push thru for welding, craned back in, turned to final size then craned out again. So probably 2 hours for a simple journal repair.

In that time I can do 4 to 6 smaller jobs that I can lift one handed and make more money.

The slotter was actually worse, you only use a slotter when it's either a weird job or blind hole, normal keyways are broached on a press and once setup with the correct broaches and guides it's dead easy.

Slotters are rare and once it's known you have one you get all the weird jobs, nothing straight forward.

Things like stainless medical or aerospace work that has something like 100 hours of work into it already, they want a 6" deep blind keyway putting in to 4 microns tolerance and if you f*uk up you pay for the whole lot to be redone.
Not worth the hassle for a £40 keyway, stick the price up and it's still not worth the hassle for a £80 keyway. Charge more and you are a robbing bastard, a no win situation.

Most of my work is small splines on pumps and fork truck motors, 3" deep max which the slotting head on the POS is capable off, suits me earns me money.

Looks like you have decided to work "smarter not harder"
Over the years many shops accumulate all sorts of jigs and other items which often were used on a daily basis but as customers change or thetype of work changes the time comes for a cleanup and rethink of procedures .
You can only keep "stuff" for a certain time before it mysteriously changes into "junk".
I have found that and after several cleanouts life is getting easier .
Now how to get rid of obnoxious customers.

So, I gather a slotting head turns a bridgeport into a...vertical shaper sort of.

Would that be a fair description?

I have never seen one in person.

From the lathes.co.uk page

http://www.lathes.co.uk/bridgeport/img10.gif


This is the genuine Bridgy head, I got a similar one off a beaver mill which was made interchangeable.

Just as good but not being badged Bridgeport fetch a far less price.

going price over here for a Bridgy head is £600 to £950 depending on condition.

A Beaver head fetches £150 to £250, again it's the name.

I maybe way out of date, but those tach/speedo housings used to be quite rare. I would think the BSA (Goldstar) or the Vincent clubs might be willing to kill for those? Am I close, at least that is what the housings remind me of.

John Stevenson
06-19-2012, 05:15 AM
They were generic parts made by Smiths industries, some were pot metal and the better ones bronze.

It was a decent little sideline, paid for a few racing holidays in Germany over at the Nurnburgh rink.

All done on a Myford ML7 using 2 or 3 special backplates that had the holding jigs machined into them. No idea where they went, didn't even know I had these castings. looked for the mating gears and found one and a half sets.

Been looking on Ebay but the ones I have found never fetched anything like what they would cost to machine.

John,
I tried to get you a job for the TOS a few years back... The <highly trained, vendor's, maintenance technicians> that maintain our 180kW diesel generator/UPS for the computer room changed the roller bearings on the 3" dia generator shaft and insisted on packing them full of grease. After the bearings had self destructed and taken 1/8" off the shaft diameter I suggester that I knew a chap 50 miles up the road that specialised in weld repairs to shafts. The bosses didn't want to know and got stung for £25,000 for a replacement shaft, shipped from Belgium, with no admission of liability from the manufacturers that their monkeys had wrecked it in the first place:mad:

I suppose it depends upon where the gears come from (bespoke or shelf) and if you have any.
Speedograph Richfield sting you about £80 for one of those (don't ask me how I know...)

Going a bit OT, that style was replaced for a while, at least on bigger engines, with a little tachogenerator with the same sort of input coupling. I'd like to find a good one of those for the engine in my tug.

I'm going to show my ignorance here. What's wrong with packing roller bearings full of grease. It's commonly done on wheel bearings. Will the grease keep the bearings from rotating?

darryl
06-20-2012, 11:39 PM
Roller bearings full of grease? Where did that come from- maybe I haven't read every post here- at any rate, you don't pack any bearing FULL of grease. That's where the probelm is, just pack them about a third full.

Can't seem to spell rihgt anymore since I saw John's shop floor and some wall spase. Seems I red somewhere that the reversal of the earths magnetic field begins in England somewhere, 'round Nottingham I think. Bloody 'el. Some big bloody motor shaft gets magnetized and hits the floor :)

It's all perfectly clear now- John trips over the naked floor and drops a big shaft. At the same time, Artful drops a charged capacitor and it shorts out on a piece of mystery metal oriented precisely east/west. The pulse perfectly resonates with the clanging shaft which disturbs the mother loadstone within the earth. All the birds which used to fly south now fly east and somehow make it to Easter Island. So bloody many of them there that the island starts to sink, tipping all that stonework over. Through yet another mechanism which we don't understand, a great crack develops in the ocean floor, and the earth spits in two like a giant eggshell. Dubbley the dinosaur emerges, waits for us all to cook, eats us, then calmly flies off into space to mother Jupiter.

I knew the government was withholding information from us :mad:

Yep!

If I unforget correctly, it's called "hydraulic locking", and the rollers don't roll because they and the grease rotate as one - result is the rollers (eventually) grow flats, then the bearing heats up and seizes, the inner or outer race (sometimes both) starts to rotate on the shaft / in the housing, everything gets expensive!

A lot of the bearing manufacturers publish charts giving the recommended grease fill, as a guideline about 30% of the space filled is close!

There *is* a formula given by quite a few sources for bearings run at 50% of their limiting velocity...

G = 0.005 DB

where,
G = grease quantity in grammes
D = bearing outside diameter in mm
B = total bearing width in mm

For slowly-rotating bearings, the pack can go up to 80% or more if it's necessary to exclude contamination, for high-speed bearings as low as 10-20% (or better yet, oil flow!)

Those British motorcycle rev counter drives fitted to unit (1963 0n) Triumph twins were originally r/h threaded into the crankcases, and hence would unscrew themselves in service and bugger things up. Later ones were l/h thread and no more problems. John has shown the 2 bolt flat flange version as fitted to BSA Goldstars, Velocette singles and Vincents etc. Also popular to convert onto race bikes inc. twins, as John said, the bronze version being a particular nice piece of kit. I would imagine they are worth at least £10 each as bare castings, say £200 as a job lot, once advertised or shown in the Classic Bike comics, one of the owners clubs spares schemes like BSA or Velo owners clubs, or speedo repair specialists would be interested, again, as a job lot. Shame to bin 'em.

Yup pie and a pint went down well. Any work round the shop is on hold, stupid customers keep getting in the way, only thing done so far is all the wood has been CNC cut for the shelves, top etc but that's still in the back of New Donald ® ™

Not scrapping the rev counter drives, they don't take a load of space up like some of the jigs and fixtures and could be valuable in useful terms more than monetary terms to someone.

As an aside I sold the toolpost and 21 holders this week, they made 30% more than the lathe made as scrap, one crappy faceplate made £25 and I still have about 4 chucks still to go.

Nephew has a bespoke kitchen and bathroom business, showroom in town and workshop just across the road from me.
As part of this he has a CNC saw where you throw a big sheet of brown stuff on up to 10 feet x 6 and then type in all the panel sizes you want and it optimises the cuts and shows you a layout of the board.
Press go and it does it. Small son can use and program it as he used to do work for Craig so he went over cut them and left it to me to go fetch them in the truck.

He also has a 12' x 6@ CNC router and a heat laminating machine where you lay all the panels out on the bed, pull a sheet of laminate over it from a roll and when you close the lid it's like a big heated press and vacuum suck the laminate onto the boards and rolls it round the edges.

Might ask him if we can do the doors and panels for the bench, save painting, which I hate :D
Not bothered about the top as it will hardly be seen and I'm going to oil it with clean oil anyway to stop it marking.

John Stevenson
06-23-2012, 10:23 PM
Lane,

'Their' is some semblance of being tidy, well not tidy but tidier, an easier state of mind to achieve.
This shop has been in existance here for about 25 years now and has slowly grown.

However growing has also collected a lot of now unwanted baggage.

Not doing a Tiffie and biting my nose off to spite my face but there is a lot of junk around that needs a new home, stuff I'm never going to use even if truthfully I never had a use for it anyway.

I have one more machine to get rid of later on, it's a floor standing pillar drill but a bit rare. It's what is called over here an articulated drill, a bit of a poor man's radial arm drill.
The table is about 24" square and the head can reach any point on it because the head is fastened onto the column on a double swivel.

Here is a picture of one.

https://www.apexauctions.co.uk/auction/itemDetails.htm?lotId=35790

They have a back gear and very useful. However they need to stand in a clear space and not be hemmed in because the winding handle for the bed is one side and the locking handle is the other.

I don't use this machine because it's not in a position to be useful.

I also have a Myford MG9 internal / external grinder crammed into a corner but when the drill has gone it will be usable again.

One of the MiG welders is going, a single phase 200 amp unit but that will be replaced by a 250 amp unit or similar in 440 volt operation, never been happy with the single phase unit but at the moment it's only a backup for the big Murex 325 amp unit.

Freaking hell... Amazing really is the word...

Can you imagine the possibilities for these machines once they come down in price more and become more sophisticated...

I can think of jobs just for making repair parts alone for old broken plastic parts made of unobtanium...

disposable casting patterns is another...

For the home machinist they will end up being an essential workshop tool...

After a few false starts he's now down to using a $29 printer from Bestbuy as the basis of his machine.

The parts bins will both face this end one was spun round just for the picture. These came from machine Mart, ower local version of Harbor Freight as di the tool boxes but I was very pleased with the quality of the parts bins, not tinny at all to say they are made out of tin ;)

The big tins are bars ends of steel brass and alloy.

Still some little bit to do, magnetic catches on doors but all the bulk is now done and I think it looks smarter than that brute of a lathe.
managed to get the wall painted and some new sockets run in given there are two more small CNC's to go on here.
The mini lathe is just a hack test lathe and kicks about all over any way.

Milton,
It's close, at the moment it's on a hydraulic lift table about 40 foot away but I have no plans for it to live on that bench. Two small CNC mills will live there that can keep working daily.

Forgot to mention one feature, the two red toolboxes have had a steel U shaped shelf fitted on top on drawer runners to hold the keyboards for the two CNC mills. Just visible in the last two photos.
The little Roland drag engraver has been fitted in the drawer under the laser but it now seems that the laser will take over from this once I get the laser marking process worked out better.
