this is my first ever you tube video so it pretty much sucks, take it easy on me... i recorded it sideways as i figured i would be able to rotate it, no dice, so tilt your head i didnt speak as i have a nice western ky redneck twang... I'm using an old blackberry for recording, so that probably has a little to do with quality.. if i knew it was as easy to post videos i would have done it years ago.. its just a simple video of the control panel operation, i still need to clean up the wiring and i plan on adding a 12vdc transformer and a fan in the top of the enclosure.., might wire in a brake resistor also.. the audio is amplfied or something, the mill is no where near as loud in person as it sounds in the video, the mill is running at 1115 or 1750rpm dont remember.. i thought this was weird, i notice the same type audio distortion in other videos .. anyone have any clue of what causes it, i was thinking just microphone sensitivity or something..the video is after i took the top housing off and cleaned it out, put in new compression springs, and new cam pins for back gear, also fixed the brake lever, added .020 to both sides of the lever to add some more brake without having to purchase a brake assembly..tackleexperts.comwww.necessityjigs.comhttps://www.facebook.com/groups/mach...dingequipment/
Reply:Neat. So you made the remote control box? I have a Hitachi X200 VFD that runs the motor on my Cumberland 810 plastic granulator. It'd be slick to add a tach to the spindle and put the display in your remote box.
Reply:yes, the box is just a small die cast box i bought for like $12. the switches are just regular 12vdc toggle switches.... and a honeywell 10k potientiometer.. i dont know if you could put a tach in the remote box and it work for a mill. the problem doing that in a mill would be you have to switch pulleys for different sized tooling in the mill so the rpm of the spindle would change as you change pulley sizes, so all you would be showing would be the rpm of the electric motor.. i could put a readout for the frequency output of the vfd in the remote box... if you were running the spindle for one specific purpose a tach would be feasible.tackleexperts.comwww.necessityjigs.comhttps://www.facebook.com/groups/mach...dingequipment/
Reply:Looks good brucer! Remember even though the B'port motors are built for plugging they still need fair speed to cool properly, so hogging for long times at low motor speeds can hurt them.The audio will get better for the next few days. Google converts everything to flash and some codecs work better than others (it's a moving target as the work on the code constantly).It used to be any sound in mp3 went the best but wmv and other sound codec conversions now work well too. They used to advise NOT to upload any sound files that include Dolby encoding.The video will also improve over time as the bots work on it.Matt

Reply:Something that actually gets its speed reading from the spindle itself - either some sort of encoder wheel or reluctor gear right on the spindle or something off to the side driven by a belt and little pulleys of equal size.

Reply:Something like this - uses a little magnet and a Hall effect sensor:http://www.floridaame.org/Plans/Kamr...achometer.html |
