WARCO WM-250 lathe family and WM16 mill - 001

Thank you very much gents for your thoughts and links, I shall explore with a cuppa.

I think at first I'd use the supplied lead-screws and I know they're not ideal but cost has to be kept to a minimum (might have to sell one of my guitars!). I have made a couple of Delrin lead-screw nuts for a lathe using the heating and splitting method. I could possibly do the same for the mill to help reduce backlash and I understand there's a setting in the CAM packages to set up backlash parameters.

Andrew, for the engraving work I have an old Black and Decker rotary tool and I believe the top speed is 24000rpm. I can probably make a suitable mount to place it alongside the main spindle for the small footprint that it will operate in. I also have a proper engraving tool, the vibrating type, but not sure that would be so good mounted on a solid machine.

Here is an example photo of the engraving I am thinking of doing. the letters are 3mm high. At the moment I'm making a guide jig to do this by hand with punches. I requested quotes to make a single stamp for this job and was quoted £78 by one company and £157 from another. both excluding VAT and P+P.

Thanks again,
Ed.

Ed: I've never come across backlash compensation in CAM programs. It would make more sense for it to be in the controller software? I guess that the other important parameter for a high speed spindle is runout, especially as the cutters are generally pretty small. The prices for the stamps seem pretty reasonable to me if you're doing more than one piece. And certainly so compared with the time, and cost, needed to do any sort of conversion.

John: I have a Series II Tormach, and it is still as supplied. At the time I bought it seemed to be the only sensibly priced CNC mill available off the shelf that would allow 4th axis machining and would cope with the size of work I do. The steppers do make some odd noises, almost musical, when machining arcs, but at the moment there is no overwhelming reason to upgrade to the Series III steppers that are on offer. Likewise I might at some point upgrade to the new controller, but there are many other more pressing calls on cash at the moment. I think the speeder (I thought it was a tripler?) is still available, but it is not cheap. If and when I need to do any more engraving or a lot of machining with small cutters (<2mm) I plan to invest in a secondary spindle and VFD, as sold by ArcEuroTrade.

I've engraved brass and Aluminium fine on my mill only running at 2450 rpm, you just have to go slowly. I tend to use a 3 flute carbide bit, it's not an engraving bit but more of a countersink. The trouble though it you have to control the depth carefully but it gives good results for engraved plates.
I'll try to find some photo's.

I also have a home built router running a Kress head, this is much better for plastics but isn't as accurate for height and XY control as it's using rolled trapezoid screws.

i purchased a rdg verion of the weis milling machines

its called the rdg -16vsm a few years ago

its the same as the warco wm14

and my motor brushes are on the way out whats the best place to buy replacements

thanks for any help colin

just waiting for a reply from warco

thanks colin

Does anyone know of a company who does a plastic cover to fit over a WM16?

Got round to my toduit list & set to making a new compound slide gib key; the original provided was an abysmal piece of mild steel, obviously hand ground at the manufacturers, why it took me so long to do a new one is beyond me; probably down to the 'get your finger out ' not being to the fore front... , any how made a new one from brass, the original was a piece of MS roughly, & I mean roughly 3.4 mm strip, that should have been a decent fit into a 5mm gap. I made the new one 4.7mm which slid in nicely giving enough gap to nip up neatly. As you can see the original bore no resemblance to a proper gib key shape, also the undercuts in the dovetail corners were far too big, reducing the width of the bottom mating face, looks like the Chinese machinist picked up the nearest slitting saw to hand & whacked that through, undercuts half the size would have been more than enough & would have allowed more bearing surface on the bottom slide, anyway I now have a much neater fitting compound slide with no tight spots when adjusted & now moves nice & smoothly when I wind the slide back & forth...

The OEM gib key...

OEM 'gib'... couldn't even get the angles correct...

Piece of scrap steel ?...

Machining new brass key...

New key, much better fit, although dovetail undercuts way to big!

Also modified the locking screw...

That's another 'mod' off my toduit list...

At the back end of last year I purchased a Warco VM250V-F lathe and this year a Warco WM 16 mill. Since I purchased the Lathe Warco have modified the Stand and fitted shelves instead of a kick plate. As space is a premium I decided to "do a mod" The kick plate came in two pieces so I fitted suitable supports and using the plates created extra shelving

I was able to obtain from work some scrap 5mm plastic sheeting and 10mm makralon from a damaged machine guard. After watching various video's on you tube and the picture of the "gold fish bowl" on this forum I decided to try to reproduce them. The rear chip guard is free standing and just slots down the back. The front guard sits on top of the table and does not inhibit the use of the "T" slot. I had sufficient material to make two guards, one with cutout for vice and one with a plain front for times when the vice is not being used.

You might want to add a couple of diagonal braces or a panel behind the shelves as the old plate in the middle triangulated the stand to reduce side to sid emovement. I went with draws under mine with a solid back to keep things rigid.

A valid point Jason. the shelves are screwed down but as soon as I can get some sheet steel I will be putting a back on for extra support. The draws look good, I never gave that a thought. now I will have to come up with ver 2

Jason B, I do like your drawer idea, Did you buy the drawer runners from somewhere. The drawers them selves, did you make these and if you did what did you make them from? Do the drawer fronts get in the way of your knees at all? Apart from the drawers being useful they make a crappy stand look a lot better too.

I agree Alan the drawers are a good idea. it is just a pity the colour is awful and doesn't go with the Warco Green

The basic 5 sides of the carcase is 18mm MFC ( Melamine faced chipboard) not the cheap 15mm contiboard stuff. Draw boxes from 18mm ply biscuit jointed with 6mm MDF bottoms, 18mm MRMDF drawfronts. Runners are easily available full extension ball bearing runners, not sure if I used 30kg or 50Kg ones.

There is plenty of knee room as the tray overhangs the cabinet and then the carrage handwheels overhang that so 8-10" knee room no problem.

I prefer to keep things in draws or cupboards, as the large hit & miss engines have quite a bit of cast iron I don't like picking things up and getting black hands so keep them away from the fine dust.

There is a space below the draws for a couple of ply "scrap" boxes where all the odd come in handy bits go.

Top draw is about 50mm deep and houses small cutting tools, inserts, blacksmith drills, centres etc

Then one that just takes 5C collets plush chuck jaws, change wheels and so on

Then an assortment in the two deeper ones below

PS I thought the varnished over yellow road marking spray was a good match to the carrage

The yellow colour may be a bit distorted in the photograph as I guess he has tried to make it the same colour as the apron on the lathe.

These benches , although they look quite nice are made from very thin material especially the top. Although my concrete floor was level the base of the cabinet and the top were far from straight and parallel.as well as being a lot less than sturdey. I ground the edges of each side of the cabinets to get them level in all planes but the middle bit where the lathe sits was very week. I ended up bolting a piece of 0.75" marine plywood to the top of the cabinets to give me a true base for which to fix the lathe to.When I checked the plywood top for being true and level after bolting it to the cabinets I found it was then spot on.

Before bolting the lathe to the plywood i inserted some lead sheet between the lathe and the plywood just in case there were any inconsistencies in the top. This made an excellent base for the lathe. I wonder how any one else got on with just bolting their lathes to the metal cabinet tops just as they came.

thank you for the description of the drawers JasonB, I didn't spot the relevence of the colour, but as Alan said were you trying to make a match? you have now given me another project to add to the "to do " list

Ditto the drawers... another item on my toduit list... already have one set of runners, just can't seem to get round 'toduit'

any use ?

Very droll, I like it
