|Thread: Vertical Spindle Surface Grinder|
George, rather than printing to your printer, in the print dialog, select the print destination as print to pdf, I haven't used MS windows for several years now but there used to be a program that allowed printing several pages to a single pdf, I now use a MAC and achieve the same result using the 'open in preview' function.
Details of your operating system, version, Browser type and version and printer details will assist in finding a solution to your problem. I've never had any problems printing pages from the older digital archives, cannot say the same for the more recent ones using the current abomination of a magazine reader!
|Thread: John Bogstandard's projects.|
Ron, If you follow Jasons link to Johns photobucket, then go to later pics, page 16 you will find the tramming tool
|Thread: Interface PCB for the ELS project|
Hi Phil, I would take a component set, already have one of your excellent quality boards.
|Thread: New lathe next week|
I put a DRO on both my lathes several years ago and wouldn't be without, although I do have a problem reading the handwheel dials due a vision problem so the big numbers on a DRO head are an absolute necessity for accurate work. If they are within budget and justifiable, then get one.
|Thread: Interface PCB for the ELS project|
Hi Phil, I'm sure I posted this at the weekend but it seems to have disappeared.
Many thanks, received the board on Friday, it looks to be excellent quality. Your documentation downloaded fine.
You may have mentioned this in the other thread but I couldn't find it, Where did you get the boards from?
I'll take a board from you
|Thread: Stepper power for autofeed on lathe|
Tony, how are you measuring the power of your steppers, I have some I would like to verify before I put them to work.
|Thread: DRO magnetic encoders - generic?|
Have a look at EMS-I, I have their consoles on both lathe and mill (4 axis on the mill which allows combining quill and knee read heads) The scales are a mix of EMS-I, Machine-DRO and an old glass scale that was on the mill when I bought it. All work without problem.
|Thread: What are members thoughts on Gap Bed lathes ?|
Having owned both Chester and Warco machines (both current lathes are from Warco) and having experienced after sales from both, my money would always go to Warco.
I've owned a GH1330 for 14 years, the gap piece comes out frequently and goes back without issue, never had any alignment issues and the lathe turns parallel (within acceptable tolerances for the work I do)
|Thread: Tingling from Myford Super 7|
'The point of PME (parallel multiple earth)'
The correct terminology for PME is Protective Multiple Earth, and is also known as Tn-C-S. (For those interested, Further detail can be found here.
|Thread: 3 Phase|
Without going into too much motor theory, hope this helps to explain:
Reversing a 3 phase motor involves changing the phase rotation, there are only 2 possible phase sequences for a 3 phase system 1-2-3 or 3-2-1, reverse any 2 phases and the motor changes direction.
However, reversing 1 winding will not reverse the motor. Each winding is electrically oriented to produce the required N-S magnetic field, as the phase rotate around the connections, so the N-S field in each coil progresses round the stator, effectively ‘pulling’ the rotor with it. Each coil in the stator is not a single winding but several that are interleaved so the stator is magnetically connected at multiple points around its axis. Swapping the orientation of one of these field winding groups essentially puts part of the rotating field into a S-N magnetic orientation in relation to the other windings and will therefore ‘buck’ against the rotation. Invariably this will prevent the rotor spinning and cause excessive heat in the stator windings eventually burning out the stator.
For your ML7 rather than a MT2 chuck, (for which you would also require a drawbar), why not buy a ER25 backplate mounting chuck and suitable backplate, That way, if you are holding long stock you can pass it through and into the bore of the spindle, with MT2 you will be very restricted in what length of stock you can accommodate.
|Thread: Syil X3 CNC Spindle Failed|
Michael, I just tried on my iPad Pro and pressing on the image for a few seconds brings up a context menu which gives the option to open the image in a new tab, which then reveals the image url. I use chrome as my browser. Using Safari, it only offers to save or copy. Install chrome it gives a lot more functionality than Safari.
If that is the same motor on your Syil machine, then why not buy the controller that Arc sell.
|Thread: Warco lathe mill attachment|
All of the WM250V lathes have the attachment points for the mill head, they also have the deeper backsplash to allow fitting without it fouling as it would on the older WM250 machines. One thing to note is that if you have fitted a glass DRO scale on the Z axis, the mill attachment will not fit.
I had a mill head for my 250V but got rid as it was of limited use and the lathe is destined for a CNC conversion.
Personally I would not go down this route and would make/find space for a separate milling machine.
|Thread: Calculating DRO For Mill Z Axis|
For the additional cost of the M-DRO summing box on top of a 3 axis display, you can buy a 4 axis display head from EMS-I that allows each axis to be displayed separately as well as allowing selected axis to be summed. I have one on my Ajax Turret mill, no complaints so far, I also have their 3 axis on one of the lathes, no affiliation, just a very satisfied customer.
|Thread: How to upset the neighbours!|
Replica of a Sebring race car. Looks like the present owner has changed a few bits, can't see the roll cage or bucket seats (that's if it is the same car as I'm remembering from some while back)
|Thread: Warco GH600|
Ian, where did you get those castors from? could do with some like that for one of my grinding machines.
|Thread: What lathes have you had?|
Chester Cobra combi machine
Chester Model B - regretted from day 1
Myford ML7, never used bought, refurbished and sold to fund other projects
Warco WMT300/2 (the one without the mill head, good machine and often regretted selling on
Warco GH1330, 15 years old and still giving good service
Warco WM250V - 4 years old and still waiting for its CNC or ELS conversion (not decided which yet)
|Thread: What mills have you had|
First on was a Chester cobra combi machine, the mill is similar to a seig x1, good enough machine but rapidly outgrew it. Next came a Chester Model B Combi machine, regretted right from the off as it was not rigid enough and the mill was virtually useless.
After that I bought a Hyundai badged X2 clone, and also acquired a Warco ZX15 round column mill. Both did their job well but when the opportunity arose to purchase a fully tooled Ajax AJT4 turret mill, for less money that the tooling alone was worth, the small mills went. The Ajax is a big machine but is more than capable of everything I will need.
