Metalguru, not sure why the file is that large based on what you have shown but you may have a bunch of unnecessary artifacts hanging out in the...
I came across an Instructable a few days ago that while it may be a bit excessive in the way it was built, may give you some ideas toward a...
Diversification is the key. You'll note all the Openbuilds authorized retailers don't limit themselves strictly to Openbuilds products. And the...
If you can't find one, you can always make your own. Make an Acme Tap
Depending on the quality of the gear, you do run the risk of introducing backlash into the system. I wouldn't expect the tolerances on $35...
Note, if you are considering belt reduction, new plates, gears and belts have just been added to the OBPS designed for just such a purpose.
V8.1 is the current version. pdf with critical dimensions shown attached below. dxf file can be found here.
I would probably stick with the non-eccentrics. Trying to rotate the eccentrics if they are not in a properly sized hole could be an issue and if...
It's hard for me to say if it is too tight without actually being there. There should be a bit of pressure but not a lot. It should roll...

A suggestion for adding length to the 40x40 sections. Trim a couple of 75mm lengths and drill the holes out to 5mm, tap the ends of the main...
The spacers were beefed up to help reduce potential deflection of the wheels/flexure of the bolt shaft. But once they were beefed up, it rapidly...
Yes. Actually two years ago, eccentrics that fit 8mm wrenches were the norm here for all wheels.
An M8 eccentric spacer is definitely something that would be useful in a lot of situations.
Paul, only the smallest size, the 20 series nuts, will work with V-slot.
Looks like a good start. :thumbsup: I've been thinking through some splices that may help you get to the 64" you need but won't have time to...
Yes, they do seem to have vanished worldwide. Alternate suggestions would be M3 sliding nut blocks or you can always print your own.
