From Arc Euro site...

'Pre+ and Pre- Buttons: These buttons allow you to preset a target measurement e.g. +1.04mm or -1.04mm. Once set, you can then move the preset distance down (or up) to zero'.

Thread: Help choosing a Chinese lathe please

Have a look at Warco site; I have a WM250V-F & a WM16 mill, can't complain, they do what I want them to do so quite satisfactory for my needs.

Thread: Any idea where to buy a square file 1/4" x 1/4"??

Surely any well known DIY store will have them, maybe your 'local' hardware store too.

The material looks like a piece of crap ! You could have made a sleeve to fit the top slide bolt, that should be a tight fit in the top slide any way, secured with an anti rotation pin. Carbide inserts work best when speed is in high range & doc is 0.5 at least, if not more. Inserts need to be worked hard to get best results / finish.

Used my recently purchased 'sensitive drilling' chuck to drill 1.6mm holes in part of my latest project... works a treat, much more of a 'feel' than using the tailstock hand wheel …

I prefer to think of it as 'attention to detail' but others will, no doubt, disagree.

No probs… one of those grey matter moments, it crossed my mind at the time … thinking

… 'I have heard of aerosol hair spray being used as a rust preventive' …

Used this myself over the years, nowadays I use clear lacquer spray available from any DIY/Hardware/ motor shops, hard wearing as it's made for car paintwork coating.

Thread: Digital inclinometers
18/08/2019 12:21:36

I have one of the digital Wixey type & it works just fine; I have made a set of angle plates using trigonometry, as described in an article / YouTube video posted a while back & checked with the digi gauge, all within... 0.01" ( minute ) so one confirms the other. I also have a digi protractor & an angle protractor on hand, a case of overkill methinks... I am one of those that tend to have a lot of 'it would be a nice to have' moments.

Thread: Making the same mistake
17/08/2019 11:02:35

Try & set it 'double' on the clock just to see; otherwise set it up to run true with a live centre in the offset centre pop, adjust the jaws to nip it, set the clock to run true on a silver steel shaft with a male & female centres in either end & you should be on the mark.

Very nice John; I'm tending to go for other colours as well rather than sticking to Stuart green & black. What is the colour on your model, it looks very similar to the rattle can colour of 'FED Aero crème de la crème' I have ?

Dave I was taught as an apprentice never to use the ratchet on a micrometer. You develop a feel for it, as you develop a feel for proper calipers and verniers

Roy

SNAP! me too, satisfying when you got to know the 'drag' on a micrometer, & the jaws on callipers. All good stuff.

Thread: New Milling Machine
13/08/2019 16:02:18

I have a WM16 & I can't complain at all at what I've given it to do. I have fitted dro's on mine, from Arc Euro , remote read out type & I've found them a great help in accuracy, wouldn't want to be with out dro's now. if, as you say they are including dro's I would go for it. Usual disclaimer.

Yesterday actually; went to my local B & Q store & bought two 6mm x 1 mtr bms rod & a meter length of 8mm square BMS as short on stock, then went around shops with Finance director.

Thread: WM16B mill
08/08/2019 08:23:02

I have fitted X & Y axis remote read out scales to my WM16, a straight forward job to do. I made a couple of extension spacers to allow me to use the X axis stops,& fitted an aluminium angle to cover & protect the read out head. The X axis is fitted on the front of my machine so I don't lose any Y travel, has worked fine for me for the past 5 years. Well worth doing.

Nice work for scratch built; if you titivate the base some more I'm sure you could sell it on eBay for a reasonable ( to you ) price. Have a look on the site & see what other variants sell for, then you will have a ball park figure.

Thread: Warco milling machines
06/08/2019 12:55:38

I have a WM16 with a 2MT spindle; I would have gotten the WM18 but got some tooling with the price difference, It fits nicely into the garage/mancave along with my WM250V-F lathe & other bits 'n' bobs one accumulates doing 'our hobby'. The mill has performed most admirably with all that I have given it to do; as with the lathe albeit I don't give either silly D.O.C. so I can only recommend Warco from my perspective, both decent machines.
