Well yes unless he's got the bearings in hand for a piston fit he can only do his best, if it was me I'd ask for 8mm OD and as Neil suggests you then tweak the fit yourself with some fine wet and dry...

If you want to specify tolerances then ask for the shaft to be machined 8mm g6 (should be within range of 7.986mm to 7.995mm) which should give you a sliding fit dependant on the bearing's...

Tippically they just request a drawing to work from so you just send them that.

Attached is one I sent recently and the machining was spot on, modify it to match what you need if you want.

I may have something suitable spare - I will check this weekend when I'm home. In the quite likely event that I forget and don't post here on Saturday, please remind me!

Morse 1 taper tailstock?

http://www.ebay.co.uk/itm/SMALL-CENTRE-LATHE-TAILSTOCK-No-1-Taper-63mm-centre-height-Dovetail-Bed-50mm-/201330652230?pt=LH_DefaultDomain_3&hash=item2ee03df446

Any good?

As a rule the point is part of the thing and not interchangeable, the manufacturers just seem contrapt their own design based around standard designs for tail stocks from dividing head manufacturers,...

I know you don't have a lathe so this is probably not going to help but i think the best solution would be a top hat type of insert drilled and taped 3mm the flange could be 0.5mm thick so minimal...

Although the link to the intended rivets gives a reference (h) for the wall thickness the seller does not specify a size. Thread depth for 3mm thread is 0.3mm so it is going to have to be about 0.5mm...

Any leather eyelet pliers will do the job and if they don't reach, then refabricate something similar with longer reach from them . If it was me i would simply instant glue each side a washer. If the...

Looks like the best option is going to be soldering to the board, i would get some 2 or 3mm brass plate cut off a strip drill and tap several holes and the cut it to a length that dives you a...

I read your requirements about position of the hole and I thought maybe a steel M3 riv-nut could be soldered into the PCB. The one I have are 4.7mm OD and 8.7mm long. I have the mandrel for the...

Slightly off off topic, but have you considered getting the PCB manufactured? It's pretty cheap in China.

You can get riveting tools to use as a method for making vias in PCBs, but they're too...

I believe all are 4 bearing, forget the crap the sellers are telling.

I decided to read a bit again the manual, to check what the problem could be.

Lets troubleshoot a bit:

1. check if by...

Just measured my spindle and I've got 4.4 ohms between phases. When driven by AC or pulses the impedance seen is higher because of the inductance, so you can't just use simple ohms law to work out...

Didn't spot this bit...



It'll be one of these:

10421

Just to be clear, you did check that the 3 resistances are the same? If off by more than about 10% (complete guess) then you've got a...

Just the base frequency setting isn't what you need, as that's the voltage at the rated frequency (400Hz), but we need to know the voltage across the whole range. Have you checked that the frequency...

Looks like section 6.18.3 shows how to configure the display to show motor speed.

A bit more heads up:

The Speed and corresponding frequencies in HZ, measured carefully with a device, you r can be slightly different but not so much. Open it in new window to see it better and...

Just try it and see.



I feel I should clarify this. The spindle is an induction motor, so the efficiency varies somewhat. The efficiency will depend on the load and the speed, so at some point...

That said for sake of 2 pipes & bucket it may be worth doing for long runs, better having the option to do it than not.
Regards Relays then Most VFD's have a in-built relay for switching external...

Hank my WC pump expired and I didn't notice, the machine cut 20mm Ali job for 2.5hrs and still spindle was only just a bit hotter than normal so I wouldn't worry about it for 30min jobs. . . . Put it...

I have water cooling, but only turn on the pump if it's doing a long stint. Just having a bit of water in the system may help even if the pump isn't on.

So, I wouldn't worry about not having water...

Hi, I told you in your other post that I have been running a WC spindle for about 10 years and have never bothered connecting up the water supply. I do keep my eye on the spindle body temp (It only...

Arc Euro have them:

How many times over the years have said do your self favor and buy some proper drives. . .Lol



If you can see it without dial indicator then they are knackerd.!! . . . If you have backlash then...
