Thread: Is it true that our access to the digital archive going to disappear?
10/07/2013 17:38:09

To me, the notice is far from clear as to what you can, and cannot do with the new digital edition.

As a humble PC user (as opposed to iPad, iPhone, etc), I need some answers before spending my cash and signing up ....

How do I download and store these editions (including the whole archive) to my Windows 7 PC? (As far as I am aware 'apps' are a feature of Windows 8 and not previous versions). How do I extract and print selected pages from that download?

I think that we all need some more details.

Thread: Roger Vanes indexing unit from M.E.W.

Hi Roy

Looks like a nice job - very pleased to see that you've made it.

I like the modifications - great idea if you want to change index wheels and easier to adjust to eliminate the backlash.

Replacing the keyway with the grubscrew makes the whole manufacturing process easier and quicker, particularly by avoiding the internal keyway in the wheel. Just one slight word of caution though - the grubscrew can never be as secure as the keyway, but as long as you lock the spindle during heavy cuts all should be fine. (I tend to be lazy at times and forget to lock the spindle, just relying on the pin).

Reading my article again, I'm afraid that I wasn't quite specific enough about the backstop thread. I did use a tap that I managed to borrow from a friend.

Hope that you enjoy using the indexing head, and would be interested to hear how you get on with it.

Regards, Roger

Agree with Niloch about the Warco DH1. Expensive, but a brilliant piece of kit.

Hi John

"For height 200+100 for the tool itself under the spindle"

Presume that you will be using the machine for drilling holes as well as milling - if so I think that you might find the height under the spindle very restrictive once you add in the height of the vice and a drill chuck / holder of some description.

Thread: Myford quick tool post question
18/02/2013 09:44:00

Hi All

Beware though, I've bought some imported toolholders where the bottom 'lip' was quite thick meaning that my 10mm tools wouldn't fit. I've now got a good number of these and there is quite a lot of variation - I've just measured some and the bottom lip varies in thickness between 5.6mm and 6.9mm.

Thread: Marlow millers and warco's
26/01/2013 15:55:11

Totally agree with Martin - the lack of quill will make the Marlow very difficult to use, so unless you just need a machine just to mill, rather than mill and drill, I would advise that the VMC would be the better option for you. You are likely to have to live with the machine for a number of years, so making the right choice now is important.

The only issue that I've got with the VMC is the distance, or rather lack of it, between the spindle nose and the table. This can give real problems when trying to use long drills on tall jobs.

Hope this helps.

If the price is right I'd be interested in a couple of feet.

Thread: Printing page on digital Model Engineer

Hi Frank

Just tried printing a page from latest MEW - no problems. The dialog box enables me to select a printer (defaults to my inkjet printer (setup under 'printers and devices' and also allows me to 'print to file'. Do you have any problems with these items? Haven't noticed the page number that Keith refers to though.

Using Windows Home Premium 64 bit and IE9.

Thread: My New Warco VMC Turret Mill
12/11/2012 15:40:38

The holes in my stand / VMC base were much further out than 2mm, so I guess that you've got the correct stand badly made.

12/11/2012 12:07:58

Hi Nealeb

I had problems with the holding down bolt positions with my VMC - Warco had sent me the wrong stand where the bolt positions were different - obviously a case of different machines, different stands. They changed the stand within a couple of days and I had no further problems. Might be worth talking to Warco before you drill the new holes.

Thread: Workshop Security
08/11/2012 14:01:26

If you have uPVC replacement doors you might think that you're safe with the posh-looking locks supplied. Apparently nothing could be further from the truth - they can be drilled, picked, bumped and snapped fairly quickly by someone who knows what they're doing.

I was advised to replace these by a policeman that I know and look for locks to overcome the threat. I chose CISA Astral S locks which are 'anti' all of the above threats. Theyr'e not cheap, but if you look around you can get some very good deals. Forget the DIY sheds and look for a specialist who can offer you a good service at what is probably a better price - I used a company called Barnsley Lock and Safe to supply my locks and had them 'keyed alike' for a small extra cost, allowing all locks supplied to be operated by the same key. Further explanation can be found on their website - no connection apart from a satified customer....

Easy to fit but not easy to break into - well worth a look.

Thread: Machine Vice any recommendations ?
23/10/2012 15:52:21

Hi Chris

Not experienced workpiece rising-up in the DH1, in fact it has very good grip holding the workpiece very securely, but you will have to adopt a different way of working with it. I also find the recesses in the top of the jaws very useful for holding thin components.

The thread **LINK** will provide you with some more information on the method of use. This method has the advantage that if the workpiece is slightly away from parallel you can still grip it tightly.

Hi Chris

I have both a Vertex K4 and a Warco DH1 and find that they both have their uses - really depends on what you intend to make as to which way you go. I've fitted tenons to the bottom of both vices so swapping over is quick and straightforward.

The DH1 is a brilliant, accurate piece of kit and is very versatile - it's overall jaw opening of 175mm vs the 63mm of the K4 sold it to me. It's not cheap if you buy it with the optional vee-jaws and high jaws (around £240 total) but these increase it's versatility tremendously.

In use the DH1 is a bit more restrictive regarding headroom (spindle nose to table) as the VMC isn't exactly over-endowed with headroom. The distance table to base of jaws is 93mm for the DH1 vs the K4's 76mm (with the swivel base in place in both cases) - not a lot but as the ad says "every little helps".

Probably the best approach is to consider carefully what you intend to make and make your purchase accordingly. If you can afford to buy both then that has to be a good option and maybe a deal can be done with Warco. After all they could both be delivered together reducing carriage costs.

On the subject of moving the machine into your workshop, it may be worth talking to Warco to see how they would move the machine as I believe that they offer an installation service. I'd be interested to know how you tackle the job - maybe you could make a posting to this forum.

Regards, Roger

Thread: 3MT or R8
22/10/2012 17:23:17

Hi Chris

Height of VMC stand is 530mm. Advise that you check the pitch of the holding down bolt holes on machine and stand before trying to move the machine itself. Warco sent the wrong stand with my machine and the pitch of the holes was different - a problem they quickly rectified.

All-up weight of the machine with stand is quoted to be 415 kg (930 lbs) and it's awkward. Yours may be a bit heavier and more awkward because of the DRO (and you will need to take care not to damage that). I used an engine crane and strop to move the machine, but if taking this approach you will need a good surface without any steps, etc. Because of headroom problems in the workshop I had to remove the head and moving the head alone took the efforts of 3 reasonably strong men (and that was after I had removed the motor). You'll also need to route the strop so that when the machine is lifted it remains relatively upright as you're handling it and locating it on the stand.

Would also advise that you put some silicon sealant between the machine and the stand. In all the excitement I forgot to do this and suffer coolant leaks into the cabinet on the odd occasion that I use the coolant pump. Will need to lift the machine and fix this problem before too long.

Hi Chris

The bottom 2 pictures show the upper part of the Z-axis scale with the reading head. The scale is attached to the main column casting whilst the reading head is attached to the knee. The detail on your system may be different as my scales are Machine-DRO and yours will be Warco.

If and when you decide to fit the Z-axis scale then create another post on this thread and I'll take a few more pictures. (I've bookmarked the thread so I'll receive notification e-mails).

19/10/2012 12:05:38

Hi Chris

Pleased that you've changed the order to 3-axis - don't think that you'll regret it.

The amount of use that the Z-axis gets will very much depend on the class of work that you intend to do with the machine, but personally I use the Z all of the time (possibly because I've got it). You'll have the same degree of accuracy with the Z-axis as you do with the X and Y, and much better than the quill dial and stops. You'll also have all of the benefits of the DRO console such as alternative zeros, 1/2 function, absolute / incremental, etc.

As for fitting the Z-axis scale, there was a thread that I contributed to last year regarding stops to the X-axis. On this thread you will see some photos which include the Z scale which my help you some time in the future **LINK**

Hi chris j

Congratulations on your purchase of a VMC - hope that you enjoy many happy hours using it.

Sorry to dampen your enthusiasm, but I would be concerned about the lack of Z-axis readout and fear that you may come to regret that decision fairly early on. Admittedly the Z-axis is probably the least frequently 'moved', but moved it will be. Also, remember that it's you using the machine over many years and not the salesman.

A good compromise might be to buy the 3-axis console even though you are only fitting scales to X and Y at this stage. Looking at the Warco website the price difference between a 2-axis console and a 3-axis console is only £54, which is very much cheaper than replacing the console to upgrade to 3-axis. Might be worth considering as a 'future-proofing' exercise.

Whatever you decide - good luck and enjoy your machine.

Hi Chris S

Agreed and I nearly mentioned that - except for the quill downfeed handle and downfeed stop scale for the quill on the VMC. These would be graduated in metric or imperial. Depends on how important the units are to you.

Hi Chris

Just had a look at my 'budget' for the job - think that the cost of the inverter, control station with extra cable, carriage and VAT (15% at the time) was £283 although that was about 3 years ago - if I had added in the cost of replacing the motor it would have been considerably more.

A quick call to John at Newton Tesla would confirm present costs and I'm sure that he will send you an information pack. (By the way, just for the sake of fairness there are other suppliers of this kit - adverts in ME / MEW).

You might also like to check that Warco can still offer an R8 / 3 ph machine to special order if you are going for an imperial machine.

Roger

17/10/2012 18:36:47

Hi Chris

You don't need a 3 phase supply to the workshop - the inverter does the conversion from single phase to three phase for you and allows you to vary the frequency, and hence the spindle speed. The inverter also maintains torque right down to fairly low revs making the whole set-up very usable.

By the way, the motor spec is 240v, and that is what Warco ordered for me.
