OK, this is another part for my Plasma cutter CNC.
This time, it is the belt tensionner. For those just joining in, I have already published a couple of other parts.
In resume, my system will use some GT2 belt with appropriate pulley and Idler. Everything was bought from Ebay.
Other than the printed parts, you will need:
2 x GT2 5mm Bore, Idler pulley
2 x 5mm x 35 mm socket cap screw w/5mm nut
1 x 10-32 x 3" machine screw w/2 x 10-32 nut
1 x 10-32 x 1-3/4" machine screw w/10-32 nut
4 x #6 x 1/2" metal screw
Pictures for assembly should be self explanatory, but if you have questions, don't hesitate to send me a message.
When you assemble the longest screw into the moving block, you'll notice that the plastic block has a portion that should normally fit a hex head, but I'm using a round machine screw: this is because I couldn't find a M5 x 75mm bolt. Had to improvise !
BTW, for those wondering why I mix Metric and SAE bolts & screws: I like to consider myself as "mechanically bilingual".... Plus I use whatever is available in my lab...
10-32 and 5mm can be interchanged no problem !
