Quick and easy Y-axis tensioners

Post by aeleus » Mon Nov 10, 2014 3:36 pm

I really liked what PsyKo had done to create belt tensioners here: http://www.shapeoko.com/forum/viewtopic ... 608#p12474

The problem was that I didn't have the metal plates to create clamps or the extra length in my belts. So after giving it some thought I came up with this.

I used the existing epoxy/fiberglass belt clips that came with the kit, a nut and bolt (you could use the same nut and t-bolt meant for the clip), and a small nail or brad to anchor the belt. It might be more rigid with metal instead of the belt clip, but there is no apparent flexing the way it is.

I've been able to get my belts tighter and, with four of these, an extra 2 inches of y-travel.

Very nice!

Also similar to what Little Hands did here: http://www.shapeoko.com/forum/viewtopic ... 174#p26328

That was already on the wiki, so added your post and gave the two their own sub-head:

That's a wonderful reuse of existing components in a better way!

Also, PsyKo's reinterpretation of the eShapeoko clamping and tensioning mechanism is beautiful, in all that brushed aluminium. :)

Thanks, indeed it was taken from the eShapeoko design :) The most beautiful : everything was done using the Shapeoko v1

Nice work aeleus.
