Current state of play

Mounted to a Watchmakers Bench.

the current motor is the traditional Universal with foot pedal.   I find the speed control terrible with any change in load while you try to compensate with a somewhat non linear foot pedal.

It's going!

In it's place, I'm going with an industrial sewing machine Servo motor.   It has a Potentiometer control, and it automatically controls around a set speed, regardless of load.  And at 500 W, it's about 2/3 HP. so Plenty of power for a 50 mm lathe.    The mount will need a bit of work, but it's all there.  The price was WAY cheaper than anything labled Watchmaker ever dreamed of.

Second.   The Cross slide needs a tool post.   Now I have a lantern one, but I'm waiting for the Cowells QCTP that I just ordered so that I can mount it  ( Thanks for the size sketches Bill, I think itll fit perfect!)

Parts are on the way....but I have a show goal to reach first....but I'm close...so maybe start on some of this this weekend.

Title: Re: Outfitting the Levin.
Post by: steamer on February 07, 2019, 11:33:18 PM
Ok the motor is interesting.     It has a potentiometer that limits the maximum speed.   I has a mechanical brake.   It also has a variable speed sensor.  This sensor is the interesting bit

It's some kind of Hall effect sensor.   It's controlled by the intensity of a permanent magnet magnetic field.   The closer to center of the sensor with this permanent magnet, the faster the motor goes.   This magnet is mounted on the brake arm, so when you want to go fast you move the lever up, disengaging the brake, and bringing the magnet closer to the sensor.   The more you move the brake arm up and away from the brake, the faster the motor goes.   

If you hold the lever up for full throttle, you can adjust the speed with the potentiometer alone.

I don't need the brake, or the lever.  I just want the POT.    So I think the simplest thing to do with it is to place a bar magnet over the sensor there by keeping it full on, and then controlling speed with the pot alone.    I'll also remove the brake, and the perhaps groove the brake wheel for use as an accessory pulley.  Plenty of braketry for a counter shaft mounted on the motor and way to bolt it to the bench.   this will work well!   GOBS of low speed torque all the way up to 3450 rpm.    WAY more than enough power for such a small lathe.   and more importantly, its much smoother power delivery than the AC universal motor.  Its also very quiet.....Much more quiet than the universal motor.

The motor is a brushed motor by the way.   It comes with a spare set of brushes.   I doubt I'll ever need them in this application though.

If you have a small lathe, you can't go wrong with this one.   Anything up to 6" swing should be fine!

OK    Some progress.   I pulled the brake and lever off, and dropped a button magnet on the screw that mounts the speed sensor and it works exactly as desired.   I'm reading up on a adjustment of soft start....Very pleased with this.

Post by: steamer on February 16, 2019, 10:40:48 PM
OK   spent some time with it an the lathe, and it'll work just fine

The traditional rocker style tool post spent a lot of time on this lathe, based on the rust stain in the plating.   and it was over tightened there as well, so I found some distortion in the t slot.  I draw filed that back to flat.  Now the post sits down and doesn't rock.   It's a pretty good size for this lathe

I sketched out a T bolt, but I think I'll make a T nut and post affair to spread the load out on these little t slots.   I'll spend some time to make the nut a very tight fit, so the lifting wont happen again.

Pictures to follow....

Well....you need to be patient.   Deals come up.   My lathe is an early lathe, and is a War lathe, so no chrome plating.   The ones that collect this stuff want the Chrome and they want it perfect....so my lathe went fairly cheap.   That's fine... I want it as a lathe, not a dust collector sitting in a cabinet!..

We'll see about the cross slide... it is a triple slide...so it will command more

Bill

Yes,,, During the war, critical material was rationed carefully  Chrome was one of those materials.   So instead of chroming the lathe, they painted it.    Hence my term 'War" lathe.

the paint is original...As to its use during the war?    I have no idea.   I always wished that old machines could talk.

This is a early Levin,    If you look at some of the out of the way parts of the bed, you can see casting problems.  Levin told me that the early lathes had casting issues, and although accurate, weren't necessarily very pretty in places.   Who ever scraped mine in knew what they were doing.  It's dead aligned with the TS, but at the bottom of the center T slot on the TS end, you can see some casting inclusion/blow holes....Not something I think would have gotten through in later years.   Its got character.

Interesting. I did a bit of googling too on Levin Lathe History and came up with this: http://levinlathe.com/history/page4.html. An interesting bit of history of the company if you read the other pages also. Seems that one of the main things they did was to make sapphire jewel bearings which had been sourced from Switzerland and the US Govt. was concerned that the supply chain might be cut off by the war. I suppose these were not only for horological purposes but perhaps other war effort instrumentation such as bomb sights, etc. Just guessing on that though. I think it's fun to know some of the background of these old machines and it would indeed be nice if they could talk!!

Yup  I remember reading up on that.   I don't think this lathe spent a lot of time running anything.  but I could be wrong.   It's just not worn at all...

I'd like to think it helped win the war, but I think that is at best wishful thinking...

Actually, ive been torn on that point.   Do I leave her as I found her?  or Repaint....The paint is in pretty good shape, It's in one piece and doesn't seem to be chipping...and it's original.

On the other hand.....It's not perfect either....

I think I'll leave it for now....and we'll get her running and if I'm satisfied with everything I can revisit the paint question....

Imperial screw, metric shank - sounds like they had two design teams in different countries!

Reminds me of the Oldsmobile my parents bought (new, right at start of new model year). When it came time for new shocks in the back, they would not fit. The mechanic finally figured out it had a Ford rear axle! Came from the factory that way - they must have been short of axles at first and found a Ford one that would fit at the supplier... All worked fine, just the shock absorber mounts were slightly different.

Well   at 20-30 bucks for a good reamer, and probably 2-3 days to deliver.    .....for 2 holes....that I'll never use again.......

Well  It's always been a "Toolmakers Reamer" to me    It's basically a D bit.

so I'll set up and put a 0.209 hole in with a #4 drill, and then bring it to 0.2165 with the reamer.

Dave
Title: Re: Outfitting the Levin.
Post by: steamer on February 24, 2019, 01:41:03 AM
It's made to size.   0.2165"  5.5mm    When it was hardened, it'll grow about 0.0002", so it'll be slightly oversize, but that's fine

I didn't draw the temper.   It's full hard..  Cherry red with a torch, drop it in gear oil.

Harder than woodpecker lips!

Stoned the cutting face .. 

It took me 15 minutes to make this tool   They work well, and saved me $30

Dave
Title: Re: Outfitting the Levin.
Post by: steamer on February 24, 2019, 01:44:25 AM
The other way to do this, is to buy drill blanks in HSS.    The blanks are very inexpensive.   Grind the angled face and you can have any reamer they make a blank for.  Which is essentially every 0.001" increments...Saves a bunch of money on odd reamers.

That's a pretty neat trick for the on-off reamer there Dave.  What's the angle you used for the end of the tool?   And what makes this more 'reamer-y' than a D-bit?   I love learning new tricks like this :)   I'll have to file this one away!

Thanks for explaining about those readers, Dave.  I have one of the EJWinter construction guides for a set of castings which includes a picture of one, but no description or even mention of any kind in the text. 

Presumably you machine guide it through the drilled hole before moving anything, at similar speed to a standard reamer.  I usually use my slowest speed (50 rpm).

I have not seen any other reference to the device so taking plenty of notice.  Are there any tricks to making it or using it that we need to know?

Interesting   I did a google search and found references.

I use it like any other reamer but you have to run it slower than hss.   I machine the flat on the mill.   I harden them and then sharpen them on a flat stone.   No tcg needed.

No engine stuff this weekend, but I did get a start on a micro drill chuck for the Levin. My goal is to get a chuck that has minimal run out on 1/8 shank carbide drills below 0.010". I've made 2 this weekend, and I've not been real happy with them..so I'm working on # 3 here. The drills are 1/8 shank PCB drills which are accurate, and plentiful, The drill will be held in with a small set screw. This one just might be the one! I've still got to drill and tap for the screw. Then I'll harden it, and draw it back to straw. It will be loctited in position on the Levin so that the alignment can be held....sub 0.0002"....this little lathe is pretty amazing....fun to get in the shop

The lathe is running!   I chucked up a piece of 1/4 round 0-1 about 1 1/2 inches out from the spindle nose and it turned 0.020 off like it was a doddle!   No chatter...and that motor isn't backing down anytime soon... I'll post up some thing this weekend...planning a busy weekend.   I need to get this shop sorted out ...

The Levin punching way above its weight...with ease. Taking a 1/4 tool steel blank down 0.050" in one pass a inch and a half from the spindle nose without tail stock support.

Pretty awful video quality...but I did take it alone.....

You know that lathe.looks a lot like my American watch makers lathe. But it doesn’t have the adjustable cross slide. By the way amazon has some good prices on digital scope. I found this one look at the zoom ratio.
