View Full Version : Linley Jig Bore
lakeside 08-12-2006, 08:55 PM I bought this little guy about 4 years ago. I paid $200 for it. Vintage 1968 machine #4167 it was used for one job and sat in the corner.I had it behind my house and cover it in grease.Now it in the basement and the grease is gone. This machine is so clean it can still hold tenths. That I think I'm just going to keep it the way that it is.The motor is a 220 3 phase should I get a phase converter or a new motor? or should I do a conversion to sometype of cnc. What do you think?
I think you should keep it in its original condition for nostalgic reasons. Machines of that nature and older are what formed the foundation for modern manufacturing. I often wish I could have kept some of the old machines I started my business with but a sixteen feet long turret lathe weighing 6 tons was a bit unwieldy to stick at the back of the garage.
Get a phase convertor.

That the way I leaning. This machine is like museum quality is there any real deference in phase converters
tobyaxis 08-13-2006, 01:21 AM Very Very Very Nice Mike. What Geof said, keep it the way it is and get a Phase Converter. You don't see those beautiful machines anymore. What type of tool holders does she take? I may have someone you can talk to.
I can't get over how clean it is as I am droolling on the key board. :D
lakeside 08-13-2006, 07:12 AM In need the following collet
Modified collets and nosepiece of the Mk. 1A. Based on the Schaublin ESX design, these collets were developed with the express intention of providing a superior grip on the shanks of cutting tools.
An important part of the new assembly was a freely-floating compensating washer which fitted between the collet and nose cap; this was intended to eliminate possible inaccuracies between the locknut thread and its inner surface which clamped against the collet.-info from Tony at http://www.lathes.co.uk/linley/page3.html
70cyclone 08-13-2006, 11:28 AM I would use an inverter(VFD)...then you can vary the spindle speed electronicly. Most VFDs I have ever seen can be run single phase with no problems and used ones are cheap on ebay.
edit: tell me what hp it is and I may have a VFD that would work for ya :)
lakeside 08-13-2006, 12:42 PM I would use an inverter(VFD)...edit: tell me what hp it is and I may have a VFD that would work for ya :)
interesting Idea so the VFD would replace the phase converter. I can't find a tag on motor but 1hp max,I would think tell me more....I did do a search and read baldor site for some info on VFD but I real know nothing about VFD
70cyclone 08-13-2006, 03:19 PM well a VFD(variable frequency drive) is what most comercial CNC machines use to control spindle speed.
most can be run single phase with a reduction in max output. if you find a 5hp drive you can program its current limit to run a 1hp without damage to the motor
couple of ways to use them...
1. just program it to always run 60hz and just have forward/stop/reverse hooked up. then it just runs at whatever the motor is wound for. (ie 1750rpm)
2. set it up with a pot and be able to vary the speed from 0 to whatever max out is for the drive(ie 240hz) this is nice because on drill presses and such you don't have to change the belt for different spindle speeds.
I prefer Yaskawa vector style drives for servos and VFDs and the build alot of other brands as well, like Omron, EMS, and others. I also like them because my Milltronics mill has them and I know the abuse they can take.
70cyclone 08-13-2006, 03:22 PM oh and you can get used 5hp or less VFDs on ebay for less than $100 really easy.
this style is what I always try to find and have great luck with...
Yaskawa V7 drives (http://yaskawa.com/site/Products.nsf/products/Industrial%20AC%20Drives~V7.html)
lakeside 08-13-2006, 03:42 PM Thanks for the info I found this one new for $260 it just the basic http://www.deselectric.com/inverters. The Yaskawa v7 drive might be a bit over kill on this one

not a bad deal...looks just like a yaskawa too...
take a look at this...Mitsubishi drive on ebay (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=020&item=300014730661&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1)
lakeside 08-13-2006, 04:19 PM I looked at the one on ebay output is only 5 amps that sounds a little on the low side. I'm just guess but 20 amps sound better. If I put the motor under heavy load would I not need the amps?
I looked at the one on ebay output is only 5 amps that sounds a little on the low side. I'm just guess but 20 amps sound better. If I put the motor under heavy load would I not need the amps?
One hp roughly speaking is 1kva, (A hp equals 746 watts to be exact so rounding to 1kva is generous). Three phase 220volts at 5amps is nearly 2kva so the 5amp one does give you enough. The calculation is 220v * 5amp * 1.732 = 1905va. The 1.732 is because it is three phase; single phase is just volts * amps.
Because this is an inverter you would normally only run one motor at a time so getting a bigger one is not any benefit. With a rotary phase convertor getting one bigger than you need at this time is worth it because you can run more than one motor at the same time.
lakeside 08-13-2006, 04:41 PM ......With a rotary phase convertor getting one bigger than you need at this time is worth it because you can run more than one motor at the same time.
It may be worth going with a rotary phase at this time as you say Geof. What size, if I wanted to run maybe 3 motors or less at a time. Less than 30hp total and by who I;ve seen Baldor

Sorry Mike, the tool holders I had in mind are different. They have a type of Acme Thread at the top of the taper (something like a CAT30). :frown:

Al The Man is the one to give you the definite answer. I think it works that if you have a 5 hp idler motor on the rotary phase converter you can run a total of 10 hp on it provided all the wires are the correct capacity. I think your 30hp total may be pushing it if you are connecting this into 120/240volt house wiring this would need around 100amps.
lakeside 08-13-2006, 06:10 PM just brought in new 200 amp service that for a small house I figuire if I add a small lathe and maybe a little toolroom cnc that where my guess 30hp came from and it's on the high side Thanks Geof think it time for Al
70cyclone 08-13-2006, 06:24 PM thing I don't like about phase converters is big and bulky, and not cheap if you want one 'cnc ready'
I run my Milltronics cnc mill single phase and have VFDs on my lathe and grinder/buffers
lakeside 08-13-2006, 06:42 PM not cheap if you want one 'cnc ready'
Well that caught my eye, Mostly I would spend more than $500 on a rotary where as the one I found for $268 would mostly meet my present needs How many real amps should the invertor kick out?Is there any advange of getting one with more amps so it could be switch between machines?
tobyaxis 08-13-2006, 06:46 PM If you want a Little Tool Room Mill these are nice CNC VMC's and they run Single Phase 220 ;)

you could do something like this (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=020&item=300014769805&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1) ...puts out 24 amps(7.5hp rated) and probably won't go over $150 used.
I personally like to use 1 vfd per machine due to programing. I currently have 1/2hp, 1hp, 2hp, and a 7.5hp VFDs under my desk right now waiting to get finished into projects. I have around $250-300 in the set. the 3 small ones(combined) take up the space of a sheet of paper and the 7.5 is about a sheet and 1/2 by itself(older unit).
lakeside 08-13-2006, 07:19 PM what do you think about this type of a set up http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330010835848&ih=014&category=41952 twice I bought used on ebay and was burned twice
tobyaxis 08-13-2006, 07:31 PM I hate to see anyone get burned. Mike have you tried Enco?
As a Note when you get the enco prices for what you want call MSC and tell them what the Enco price is. They will more than likely match the price for the same product. Enco is Owned by MSC ;) You'll be getting new so if it doesn't work you can return it.

70cyclone 08-13-2006, 07:37 PM not a bad deal for one of those and they claim the 'cnc ready' on their stuff
I know it sucks to get burned on ebay or anywhere else. Guess I'm lucky, only time I have been burned on ebay was for a set of NEW car wheels, not used electronics...
lakeside 08-13-2006, 07:48 PM Think I'll give them a call Thanks for your help 70Cyclone

With a standard motor the maximum advisable frequency would be 120hz if its a 4 pole motor or 60hz if 2 pole.
If this motor is 2 pole and you were to run it at 240 hz (14,400rpm), it would probabally disintegrate :violin: .

true enough...can be fun to toast some old motors at 400hz though :nono: :eek:
lakeside 08-13-2006, 08:22 PM Al I think my question at this time is,What size rotary phase convertor would be good to buy at this time, option 1-VFD invertor for just this machine (new) or option 2 spend a little more and get a rotary phase convertor for this machine and maybe 1 or 2 more down the road I'm looking at this one now http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330010835848&ih=014&category=41952
Al_The_Man 08-13-2006, 09:04 PM I made a 7.5hp from a used 230v 4 pole motor for around $220. (see some previous posts).
It depends on if you want the variable speed option, if looking for fixed speeds for more than one machine, then the RPC may be the best.
A VFD will give you speed control, obviously.

Al you could make one out of a soupcan and some wire I bet :)
I would not know a 4 pole from a 2 pole from a tadpole. I Think that a RPC might be worth the money. anything I might add can be hook up as for the Linley it's only light duty mill at best so pulley changes are not that big of a deal Thanks all for your time Let see what happen to this little guy Linley
......Thanks all for your time Let see what happen to this little guy Linley
All day I have kept looking at your pictures and reading the posts. Obviously you need to make a decision. If you are like me you do not like making decisions so I have a suggestion to take all the worry of your shoulders.
You paid $200 four years ago, you took some time to cover it in grease for storage and then you cleaned it up. I think 3 hours is a generous guess for the time you spent greasing it and cleaning it and at $50 per hour that is $150. If you had left the $200 sitting in the bank it might have earned $10 in interest over four years; so your investment in this machine is $210 plus $150 for a total of $360. I am a generous fellow and I think you deserve to double your money! Therefore to save you all the worry about phase converters, and VFDs I will buy this little fellow from you for $720 :D
P.S. You have probably figured out I am joking; you are right, I don't expect you want to sell it. But if you do .................
tobyaxis 08-13-2006, 11:25 PM :D The humor here is the number two reason for visiting. Thanks for keeping it real Geof ;)
BTW; Mike, this is an example of a useless post. Geofs' is just plain funny and I could not resist posting this. :cheers:
It's bad enough to interupt a thread but in my interuption I made a mistake in the post DUH (chair)
lakeside 08-13-2006, 11:38 PM Geof by the time you add shipping to Canada of about 1k it would still be a buy. You are right about one thing I had to do is making decisions The dam phase convertor and shipping will be more than I paid for the machine..My wife has be complaining about it for 4 year it sat out back. If she even find out how much I'm going to spend to power it, she will flip.But she dose not need to know everything.
tobyaxis 08-18-2006, 08:46 PM Mike have you found collets and tool holders for your Jig Bore yet?

lakeside 08-19-2006, 03:04 PM The point Jay made to me over the phone was when selecting a rotary phase converter to be on the safe side take the motor HP x 2 =RPC HP size (for hard start like lathes without clutch)
xjdubber 11-19-2007, 08:12 PM anybody ever cnc a linley? Im thinking of it
Adethelathe 11-28-2007, 10:18 AM anybody ever cnc a linley? Im thinking of it
Hi.
I am new to cnczone and don't know all the ins and outs.
I have UK version of the Linley which is called an Elliot MK2. Check on the link http://www.lathes.co.uk/elliott%20mini%20jig/ to confirm if it is the same machine.
I have only just started and am just working on the "y axis". Progress will be slow as I am still in full time employment and thus only get odd evenings and a few hours at weekends.
I have made a new block and bearing unit for the Y axis, together with a new block to fit the ball screw nut. I am just assembling this and hope this will act as a learning curve for the other 2 axis.
One issue is the x-axis as there is not a lot of space and I will have to use smaller Ball Screws than I would have liked. For ease of manufacturer I have opted to use flange ball nuts rather than threaded. Threaded ball nuts only seem available over here with metric threads such as M26 and I didn't fancy buying a die this size or cutting an internal thread using my lathe.
For the Z axis, I am thinking of using the whole movement of the head rather than trying to modify the quill feed which I will lock in position. The head seems well counter- balanced and does not seem to have any inclanation to move up or down or its own accord. This may change when I add the stepper motor to it.
Finally I am thinking of using Mach 3 software.
I have produced some drawings on TurboCad - which I am also learning at the moment.
Hope this helps.
lakeside, I don't know wear you're at with your Linley project but, seeing the Linley name on the forum listing caught my eye so I'll give you my two cents worth if you like.
I have a very late modle Mark 1A, by the serial # it was probably made in the last year or two befor they stoped production. I have been in the prosess of repairing/restoring it for a little over a year (little bit here and there as time alows)
It was given to me by a friend who baught it from HGR Indusrial Surplus in Ohio.
It was sent a few hundred miles to his place in NE Wisconsin by FedEx Ground.
Apparently when the driver left HGR in Ohio the machine must have fallen over on its pallet and rolled around in the back of the semi all the way here.
As a teatiment to the strength of the machine nothing more than a hand wheel was broke and only a few more things were bent.
The scratches and gouges in the piant are painfull to look at and most of them go right through the body filler (used by the maker to give a nice smooth appearence) down to the bare casting.
Long story short, she's comine along nicely and I expect to start using it this winter.
I guess in the long run FedEx was not the cheapest way to go.
As to the Phase converter issue. In my basement shop I have nothing bigger than 1.5 hp dual speed motor on my Harding horizontal mill and I have three of the five machines that require three phase power everything else is 220 single phase.
I built a rotary phase converter using a 3hp three phase idler motor and a static phase converter rated at 5hp max.
My converter simply starts the idler motor and is then taken out of the loop and the machines are run on the 3 phase that is produced by the still running idler.
The whole thing cost around $200. to put together and I can run any number of motors from it at a time (within reason I'm sure) so long as I start the bigest motor first (spindle motor then feed motor then coolant pump if so equiped )
In my case I am the only one useing the machines so I don't worry about stalling out a running motor by turning on a bigger one on another machine.
As I understand it you could just hook a static phase converter to each machine that needs it but you don't get full power as with the rotary modle.
So far I'm very happy with my set up and when I want to add another 3 phase machine to the throng I pull it off a buss bar in the three buss distrobution box I salvaged from a company I used to work for.
BTW I would not be tempted to try and covert your machine to CNC. Take Geof up on his offer and put that towordes a Bridgport CNC if that is what you're looking for. The Linely is just not designed to be a CNC.
