Re: [Emc-users] glue question?

You CANNOT expect any high-strength bond on HDPE that rivals the strength of the material, not with any glue. Typically it is bolted. E6000 (same an Amazing Goop except uses PERC solvent instead of toluene) is the highest strength. Locktite makes a system for cyanoacrylate where you use a

Re: [Emc-users] glue question?

In general, no matter what your glue question is, my glue answer is epoxy. HDPE is almost as difficult to glue as UHMW or Teflon. Very low surface energy. I'd recommend cleaning with isopropyl alcohol to remove every trace of oil from the surfaces (HPDE and panel), allow it to air dry, and

Re: [Emc-users] glue question?

I think there is some super high end glue that 3M makes that will glue HDPE, but most people don't bother trying to glue it. I would consider stapling velcro to the HDPE strips.I've had very good luck using the industrial strength velcro that 3M sells, not the Velcro brand. I've mounted

I went to the orangepi.org page and clicked on sellers and it can be bought for $9.99! Wow.. crazy! 8-) The cords will cost more than the computer! I think I need to raid the spare change jar and buy a few computers. Dave On 10/22/2016 3:52 PM, Nicklas Karlsson wrote: > Seems like a cheap good

Seems like a cheap good LinuxCNC computer, maybe a split between user interface and real time is not needed. If I get it correct software is stored in flash and then I guess it also boot fast. On Sat, 22 Oct 2016 13:44:47 -0500 bari wrote: > The Orange pi is ~$15 and

Re: [Emc-users] A couple more of the $16 questions

Unless the motor is inverter duty rated, it was designed to run at the base speed on 60 hz - typically for years without much or any maintenance. Typically, I think you can get by with 2x base speed on most small motors without a very short life (less than a year of continuous operation).

Greetings all; Since I will be useing this vfd, as opposed to a treadmill motor with one of Jon's excellent pwm-servo amps on this lathe, I'll have quite a number of options to get the spindle speed I'll need as there's the backgear to really slow it, and the 4 step pulley setup inside the
