ML7 gone to another home.

05/04/2012 17:08:14

Just had delivery of my Standard Modern 1334 Lathe. needs a paint and some cleaning but so far seems to be OK.

So my ML7's days do seem numbered. Any interested parties are welcome to contact me.

Help/Advice sought.Which do you think would attract the best price?

i am considering sellig my ML7. its a 1973 machine in exceptional condition. no play on the saddle. the head is within 1/2 thou over 8 inches.

Can be supplied full CNC with C2 ground metric ballscrews or returned to original manual.

Has 3 Jaw & 4 jaw Pratt Burnard chucks, Dickson type (Bison) toolpost with 3x turning holders and 1x boring holder and 1x cutoff holder.

If manual also has a digital RPM gauge.

All answers/comments greatly appreciated.

Thread: Myford ML7 - advice needed please

Hi Bob,
Myford ML7;
you can try posting and advertising on ebay. some good pictures will help.Advertise the lathe with the basic of tools, i.e. a 3 jaw chuck, centre (if there is one), some of the cutting tools, etc.
Any extra chucks, or "special" tools, I would again sell on ebay.
Do make sure you set a minumum limit to accept on these or you will be giving them away.
I bought mine some months back for £460 on ebay so similar should be achievable. I paid £100 for a 4 jaw Chuck,
 
 Alpine;
again try posting on ebay, it is a nice sturdy machine and should if in even the most basic config fetch around £300. if it has been converted to CNC the double this figure. Again i wouls sell it with some basic tools to attract buyers, but then sell the rest of the tooling seperate. i.e any special vices, or work holding like a indexing vice, etc.
 
Unfortunatly on the models i would try contact your local model engineering society, at least so you can get an indication of value. Too often loved-ones are taken advantage of in this grieving period by people offering to "take" these items off their hands.

Thread: Tachometer design
04/03/2010 16:22:25
i found the uA723 to be a good low cost psu control ic. and for a few pounds you can easile build a 0-30V 0-3A power supply.

i must however point out for those of you who now have a raised interest in developing your experience and hopefullly own projects, that this is not a cheap hobby.
 
you will need;
Variable Power supply ~£60 - £300
Multimeter £10 - £100
Breadboard £4-£8
Test Leads £2
Oscilloscope (very difficult to find problems without) £200 - £2000
MPLAB (good starting point for code creation and debug-----it is FREE).
 
nice to have
Function generator ~£100 - £1000
Frequency/period counter ~£150 - £1000.
Schematic/PCB capture ~£150 - £6000.
 
So if the cost of setup has not yet frightened you, welcome to the world of Electronics where we all (Electronics Designers) have an absolute passion for the field.

To Dave Tointon:
 
Hi Dave,
Try Elektor Electronics (www.elektor.com) they often have beginer projects for PIC.
Other sites to try are:
 
and make friends with people like Les and I, who have experience with microcontroller design.

Has anyone in the group had and good experience with Amadeal. i find that Hugh is quick to say why his product is superior but further communications fell on deaf ears.

John,
 
I echo your thoughts, Thanks Les for the offer of a low cost, easy to assemble and functional Tacho.
 
For those of us into Electronics Design, we can either accept the project as is or if you feel you can improve then do so.
 
As for choice of micro, using the onboard comparitor is not difficult but will add overhead in code and time to execute instructions.

Yes thank you all for such fast response.
Geoff if you sell this book please put me down for a copy when it comes back in stock.

Hi all, does anyone know where I can get some plans on how to make a tool post jig for sharpening lathe tools on a bench grinder?

Hi Les,  I too enjoy working with the PIC micro's and use Proteus for Schematic and PCB capture. if you are willing i would be more than willing to offer my assistance with this project as i too have been looking to create a hall effect RPM meter for my lathe.
 
Do you have or have you yet created the code for this project, if you have could i perhaps have a copy?
