3 * RM1610 ballscrews, 780mm & 660mm

[Jonathan]

I have three new ballscrews to sell:2 of RM1610-780mm, 2 ballnut, end machining(F=25mm)1 of RM1610-660mm, 1 ballnut, end machining(F=25mm)They are end-machined in the normal fashion except the cylindrical portion has been made longer, 25mm, to accommodate fixing pulleys more easily.Will sell individually or as a lot, don't really care. Can cut to length and end machine if required.



Will consider all offers...also interested in exchanges for something good, like profile rails...

Shit Jonathan I've just ordered 2x800mm from Chai and these would have done the job. .!!!!!!!!!!!!!!! I'll see if he's sent them yet.

Did they come machined or did you do it.?

[Jonathan]

Chai did it, why do you ask just out of interest?

[JAZZCNC]

Chai did it, why do you ask just out of interest?

Because you shit on a lathe.. . .:rofl:. . . . . . .No Sorry actually would have been better to ask if you machined them to match the BK/BF blocks that's what I was asking for really.

With them having 25mm shaft then I wondered if you had done them for a special reason and none standard bearing block or self made design. No slur on your machineing prowess and would or will happly bought/buy them if you had machined them to match BK/BF blocks.

Edit: I've just emailed Chai to see if orders been sent or too late to cancel the screws so may be intouch.!

[Jonathan]

No, easier pulley alignment is the only reason so they'll fit BK/BF blocks. I wouldn't be caught dead with a BK/BF block anyway.

[Swarfing]

Jonathan just PM'd you

[JAZZCNC]

Nah now't wrong with them they just need a little TLC some times thats all, certainly can't make them any cheaper.! . . . Anyway I'll be using FK/FF blocks.!!

[Jonathan]

Much as I'd love a higher bid, if Jazz cancelled his order and I sold the screws to 2e0poz, then that would have been a bit harsh on Jazz so I thought I'd wait.

FK/FF blocks are the easiest to make as all the accurate bits are on the lathe. How much do you pay for them, lets see if I can't do them cheaper :naughty:

Go for it.!!. . . Just payed 60 dollars for 4 so thats £38 or £9.50 each. Plus a bit of shipping but thats mixed in with everything else I've ordered.

[Jonathan]

Ballscrews are still for sale.

Jonathan out of interest why are you not using these on your milling machine? You said you were going to upgrade it at some point?

Same reason that John S hasn't bought them - 10mm pitch is suboptimal for the milling machine or lathe.
They were going to be used on a machine I'll soon be making, but due to design changes they're no longer suitable so I'll be buying longer ones.

Go for it.!!. . . Just payed 60 dollars for 4 so thats £38 or £9.50 each. Plus a bit of shipping but thats mixed in with everything else I've ordered.

How much does the shipping work out at if you calculate it proportionately by price? Assuming that's £9.50+shipping per pair of supports then it's not going to save much. I'll still make my own as it's so much less restrictive and guaranteed not to have dodgy bearings or the wrong fit on the bearings.
