Hi Chris

In the part-list, you have listed a 1/4in shaft collar. I haven't figured out where to use it, could you please explain?

I am also wondering on how you attached the lead-screw to the ball bearing (in the opposite end of the motor). Did you use any glue on the lead-screw to fasten it to the ball bearing? On the rail instruction video, you just presses the ball bearing in the “hole”. Do you use anything else to secure the ball bearing?
Could you please take some close-up picture of the end-area without motor?

Thanks

WIth our rails the hole in the end is just the right size for a compression fit for the bearing to fit.
The lead screw just sits within the hole of the bearing
the shaft collar is used on the leadscrew right up against the same bearing and tightened up. this ensures the leadscrew does not chew into the far end bracket.

Hi Flozc. You're the other norwegian here right?

Where did you buy your lead screw and nut from?
I'm having trouble with my screw and would like to order a high quality screw this time.

And how much did it cost?

Hi, for the lead screw I bought a standard M10 lead screw that was 2 meter, since my rail is 1,5 meter. I searched for a lead screw that was made of stainless steel, but could not find any that was 2 meter. The lead screw made of stainless steel seams to be a bit stiffer, and of higher quality, If you have a rail that is 1 meter, it should be enough with a M8 rod. Both Biltema and Clas Ohlson have them.

I haven't found any anti backlash nut, so I decided to make my own. I will post some picture of it when it's finished.
