I came across some HDPE for a very reasonable price. I was hoping to try it for gears but it would be CNC cut instead of laser.
We will see how it goes.

Tim I was told that the name Derlin was a DuPont trade name. and this Acetron was the same stuff but made by another name only. If you feel the Derlin on my split nut, it feels the same as the Acetron, If I get a chance I will also use the UHMW. It is easer for me to find, (but I have not priced it $$$ wise in many years.)
More latter.

Looks like a lot of properties similar to Delrin Curt. I still think we should try UHMW too, though I want to get some of that stock you have there. Kind Regards,

Hello Everyone, And Good morning to all. ;-)
Mac. Yes the new gears are a heavy 1/4" the old ones were 3/16.
Jeff. I'm not really sure why they broke? I think it could be the plastic and metal meshing, but it also could have been the cold temps in my shop? Due this Question, I made the second gear to try to find out for sure why? A third possibility could be, the my mounting of the motor and gear set-up, Perhaps the gears were not set correctly due my my brackets having to much play in it??? ALL That I can say for sure is, What I have now, And that I have a lot more testing to do. PVC is very hard, and it looks to me at this time the hardness also made it a little brittle. I am hoping that this Acrtron GP plastic will hold up? Bye the way. This is what I found out about this product.
Have a good day everyone.

Thanks for the update Curt.
Was the tooth failure between the two pvc gears or between a steel and pvc gear?

Hello Everyone.
Sadly the PVC gears that I made last week, started to chip and break. as I was using my machine last night.
So this morning, I was able to find a different type of plastic, and I was able to make a new set of Gears that should hold up to the Legacy. The material is called Acetron GP. (Its not cheap to buy, but I was told that it should hold up for my gears that I am making. And it is Laser friendly, So I bought some today.) Here are some photos. Tomorrow I will do some more testing, with both Acetron gears as well as with my Original Legacy gear that I used for my specks.
Please let me know what you think? talk to you all more latter.
C.A.G.
