I have been Emailing Fred to get a quote for the rails
I have my 1605 ball Screws from my original design and order but I see everyone seems to use the 1610 ball screws on a 1:1 pulley instead of the 2:1 Ratio but would it be okay to use the existing 1605's or is it worth buying the 1610's from Fred whilst I'm getting the rest shipped over.
I wasn't sure if I make any gains of Torque and speed this way?
I also have a pricing of the 2.2 Spindle and VFD I thought again just one shipping might be good but I haven't really heard of anyone having the spindle from Fred. I know the old adage of the finish the other things before they are needed but I am buying some of this to use in my business and trying to save a little from my Tax bill
any help would be most appreciated.
Thank you
Rob

If you are ordering anyway then I would get 1610's if it's being used mostly as a wood router because you'll want the extra speed they offer. Don't worry about torque because if you use correct size steppers with a decent amount of volts you'll have more than enough torque. If your just cutting aluminium with it then 1605 will be fine with a 1:1 ratio as you won't cut much above 3mtr/min and you'll get around 5-6mtr/min rapid speeds which is more than enough for smaller machines.
Fred's spindles are fine, I have fit dozens and not had any troubles yet, they are pretty much all the same and in general, I have fit 100's over the years, and less than 6 have gone faulty on me.-use common sense, if you lack it, there is no software to help that.

Hey Jazz Thank you very much for that, Righty Oh I will add them to the order it won't be a bad thing because the originals I have don't have much room for a pulley. I'm sure they will get used for something else one day.
I will add the spindle too and then just hope that the customs people don't think it looks interesting enough to open :)
I'm still undecided to go with the oem or Hiwin Rails the difference is $325 dollars and because I want to do it right I'm leaning to the Hiwin.
Thanks

I have don't have much room for a pulley.
That is where the pully fits.if you make it too long you can always cut it off.25-30mm is fine..Clive
The more you know, The better you know, How little you know

Hello Clive thank you for that I wasn't sure on that part,
I have a 300mm ballscrew which is the 1605 from when it was going to be a round rail system would it be a 1610 for this too or will I be able to get away with the 1605 for that?
thank you
Rob

Hey Jazz
Perfect That's Great News, Yes the plan is to use a belt to the screw, it doesn't have much of the end on it but I thought I can open up the pulley to go over the thread slightly or use a coupler and a short length to the pulley although I thought that might get some backlash so hoping to go with the first option.
Thank you very much for your help.
