Schaublin 125-CNC retrofit.

Hi Andy,
That is a nice design. 45 tall, and 135mm square? Nice. The Schaublin has the little D1-3. The through hole of the Schaublin spindle is 32mm. What size core are you planning? I fear that the post, bank fees, and customs will drive the price up so far that it would be cheaper to hog it out of a meehanite bar. There is a pretty resonable seller on ebay.de. Currently, I only have a cheap 150mm rotary table. I have been sort of watching out for a Nikken NC fourth axis, but at this stage dont really know what I will end up with.

Parcelmonkey says £15 to post 3.5kg of cast iron from the UK to Austria.

The raw casting will have a 40mm central hole, for a 3.5mm width on the top of the taper ring if machined for D1-3. Which ought to be plenty for a static application like a mill or rotary table.

No eBay APP ID and/or Cert ID defined in Kunena configurationThanks for the offer Andy, but I think I will pass of this one. Customs will add 20% VAT on the item + the postage cost (barstards), and maybe a few percent for tolls, and then the post will add a further customs €10 handling fee on top of that (same).

So the 35GBP casting becomes

35+15
=50GBP
€58
+€10 customs handling
+20% = €11,80
So the final cost is about €80.

I have so many costs with getting all the hardware to convert and equip the Schaublin at this time, I really cant justify a speculative punt on a future project. Better to wait till I actually need it, and buy a billet of Meehanite from:

Fairy Nuff.

Though you won't get a 135mm square out of a 150 bar, you would need the 180. But then with D1-3 you might not need a 135 square.
(Though I sized it to span all three table slots on my mill)

Yeah, when I get to that point, I'd have to measure my tables slots. Look forward to seeing your video on pattern making, and then machining the raw casting.

Given the same price and size, to drive this 3kW motor, would you take the 5.5kW VFD ans derate it, or take the 3kW VFD?

An oversized VFD is never a problem, you can always reduce the max current.
But if it is undersized for the motor (and some older motors take a huge current at zero speed) there is no way round it.

If they really are the same price and size, then it's an easy decision.

Pattern-making is boring. I just 3D printed it.
