It's all amazing pizzano . The drone thing would be so helpful for rock hunting. I did have the fortuhnicity of Google Earth satellite images via the cell phone to find rock covered bald spots located in the mesquite and cactus shrub lands of south Texas for hiking to. But not all locations had the cell signal. The drone would have solved that problem. The difficult to access open patches of ground were the agate and wood gold mines. Just wear thorn protective clothing to do the short hike ! The same game with other types of vegetative cover in this part of the country like timbered clear cuts and construction activity where ground exposures occur but not yet shown on Google Earth. James, I can see where a drone could be helpful for rockhounding adventures. I've used Google Earth before to locate likely picking sites, but what you said, outdated maps. Then there's bad cell coverage in some locations. But a drone would be cool. Just try to keep it out of the reach of eagles and other birds of prey, like this one over Michigan yesterday - U.S. NEWS Bald eagle takes down Michigan government drone The device was mapping shoreline erosion when it was attacked in the air. www.nbcnews.com/news/amp/ncna1236687?__twitter_impression=trueWe'll, the video didn't post, probably because it is not YouTube. Here's a link: www.nbcnews.com/news/amp/ncna1236687?__twitter_impression=trueI can't remember what birds of prey they had in south Texas Jean. Here in Georgia hawks are very common. Owls too. Throw osprey in the mix. A bald eagle would be the worst case. I have seen videos of drones getting attacked by various birds including some waterfowl. It spells disaster for the drone in most cases.

pizzanoDid some brief research on UAV mapping. That is some powerful mapping stuff. I may have seen a video where UAV was used to see anomalies of primitive man's settlements on the jungle floor ? I could only dream about using such a powerful mapping tool. My Dad and I used to do RC airplanes. He was a fighter pilot and did the gas powered stuff and I did gliders. Some of the gliders used large rubber band propulsion to climb to elevation and then the prop folded up for long glides. With the new dc motor tech RC glider's hang time would have to be greatly improved. A camera mount for an electric glider would be real interesting. Not sure if I could wade thru the UAV software but just having a fine resolution camera onboard a glider would be a rush. You are fortunate to have a job that would pay you to educate and use UAV. Lucky you. I invested in property in say a 25 mile circle around Lake George in Florida and used to hire a glider pilot to take me up from Pierson Florida to see property from above. Pierson is known as the 'cut flower capital of the world' and used fast airplanes to deliver cut flowers around Florida and to Florida airports. The powerful airplanes were used to pull gliders up and Pierson became a glider community. They maintained a powerful ragged out crop duster to do the towing. Anyway, for ease of flying and longer hang times I was hoping to do the more passive camera glider drone thing. Maybe you have experience with them ?

Anyway, for ease of flying and longer hang times I was hoping to do the more passive camera glider drone thing. Maybe you have experience with them ? You're most likely referring to the UAV LiDar application.......the military, mining and archeology industries use. Very expensive and takes quite a bit of specialized training to process the logistics and data transfer. Never had an opportunity to use it.
I'm only experienced in slope gliding, where the craft has a small motor and retractable props used to chase thermos and climb.........wasn't my cup of tea. The photography interface aspect with gliders is tricky and not very useful in mapping. First weight is an issue, that means anything used has to be light and smallish, which reduces data storage and field of view aspects. Second, logistics become a problem since gliders rely on air pressure zones to stay afloat, meaning specific grid patterns can't be detailed due to the constant changes of fight direction and altitude adjustments required to fly. It is possible to use a "glider" for surveillance, but you're talking one huge wing span, the ability to climb and stay up at very high altitudes and very expensive photography equipment, like law enforcement and military use............and a specialized license to operate at such altitudes.
Initially, all of my training and license costs came out-of-pocket. I and two other engineering buddies started the journey as a way to stay current and have the ability to fly within the increasing shrinking air space limits. We all started out with 500 class prop fixed wing craft, simple quads and handheld cameras like GoPro's. Eventually, the hobby turned into a way to make money, since we were being recognized by up and coming commercial ventures with real estate and aerial mapping needs. We started out filming energy drink sponsored (Red Bull, Monster, Rockstar) sporting events, mostly promo car and truck dirt racing. I and one of my buddies were approached by a Civil Engineering firm we had both worked for in the past.........and that's when we took our professional job experiences and applied the UAV technology.......... On only one occasion was any of my costs associated with UAV, covered by my employer. It was a huge investment and I was very fortunate and appreciative to have been exposed to such. We were sent to a school (now defunct, bought out by a huge conglomerate out of Utah) down in San Diego, CA. We spent a week and a 1/2 down there, 12 hour days, learning ALL of the craft aspects, flying, building, repairing, programming.......photography, software interface and licensing preparation. After which, we took our knowledge and tools to practice. Eventually, making a small living and return on the employer's investment.
All said and done, it took us about three years to become solvent........My buddies have branched out on their own and work for a firm in Provo. I, on the other hand, had life responsibilities that prevented me from expanding the Professional side of the income curve potential. So, just continue to contract my services with a couple of small local firms that provide digital aerial topography related to land development and construction. I seldom fly any of my feeble craft anymore. I get my fix when a job comes along........keeps me engaged and somewhat current.......but the constant tech up-grades can be a challenge.....!

Throw osprey in the mix. A bald eagle would be the worst case. I have seen videos of drones getting attacked by various birds including some waterfowl. It spells disaster for the drone in most cases. There are two recommended methods to prevent aerial wildlife conflicts.........research and scout the existing habitat prior to flying and choose the proper type of craft (color, size, sound, mobility).....and fly at altitude with the least amount of sudden and drastic direction changes........in rare occasions, that might not work either, given the time of year, number of hungry and young species being protected and just ornery combatants.........I've only experienced that problem once, a California Condor near Simi Valley, CA............being so rare, I gave no thought of such, but it was big and determined. Came out of nowhere above me. Lucky I saw it diving......was able to drop the DJI Phantom quite rapidly from about 560' feet to 30' and take cover under a very large Oak........but that bad boy still tracked me until I got the craft down next to my truck..........he circled my position for more than an hour........we packed up and went home.......lost a days wages on that trip.......!

What a cool profession drone applications would be. Ultimate photography and mapping perch. Amazing quality of video coverage. I get the use of high tech mapping apps. Just sounds too cool to be true. And filming rec events.
I just want to tinker with video photography say in the US govt owned mountains. Rivers too. It is so desolate up there I doubt the law would ever complain or bust/catch me for that matter. Plus there is a privately owned corridor about 1 mile wide and 15 miles long, basically the river valley surrounded by mountains that might do for my desires.
I do complain about the hang time for a drone so I bought a Mavic Mini for like a 20 to 25 minute hang time. If I did get busted and my rights terminated life would go on since it would be a hobby thing.

EricD are you a drone man too ? I think I am heading to the hardware store to buy some M4 screws to make the Lot-o rig work. 6mm drill to drill holes in some kind of a counterweight to mount on shaft. Drill a hole, tap, do set screw. I have a spring kit, mine has a broken spring to replace. I don't see the higher frequency breaking springs since I intend on running a lower vibration amplitude but who knows. Wish I could get some 6mm shaft clamping or set screw collars. Adjustable like the Vibrasonic via set screws. Lot-O adjustable counterweights.: But on the little motor output shafts instead of this idler shaft:

EricD are you a drone man too ? I am not, but easily could be drawn into it. I tend to prefer full-scale machines that can be used for personal transport, but that doesn't rule anything fun out. I had a couple RC helicopters before. They were extremely fun!
I like your adjustable offset weight design

Sweet, and made out of carbon steel for weldability. Thanks for finding this. Depot did not have 6mm or any metric drill bits for that matter. They had M4 hex bolts though. Thanks for locating the 6mm collars.

Check these out EricD. Found these flangified units next to the link you supplied. Then crossed to EBAY. To avoid welding such a small item, bolt on instead. Maybe a fan blade can be flange mounted too. speed packed from China:

Took some time this morning to sort thru fasteners and drill holes in flange washers. Had to prevent bolts from hitting armature using spacer washers. Lock rings mandatory due to vibration. Holes drilled, flange washers mounted. Overall width is less than 1/8" longer than Lot-O motor. Overall diameter is 3/8" smaller than Lot-O motor. Should be close enough to bolt into existing motor mount.

Proud of retrofit. Had to drill Lot-O frame. Tedious job. Also replaced one set of broken springs under motor, a pain to do. Add counterweights and she's ready to go.

Yay, let's see! The real question is - if this works better to reduce brusing etc - how much are you going to charge us to send you our lot-o's to retrofit them? LOL I don't have the knowledge, skills or access to tools that you have

LOL I don't have the knowledge, skills or access to tools that you have Yikes, that's a scary thought saxplayer ! Maybe Lot-o would have legal issues to pursue who knows. Some jigs need to be made to streamline making the parts for sure. Finding metric fasteners and specialty washers slowed things down too. I would be glad to post a parts list. The motor might be a one-off and stock may be limited. It seems like the motor was made for this job specifically. The increased vibration rate may increase abrasion rate saxplayer. Will see, may be a flop but it seems like a good chance for improvement in several ways.

Will see, may be a flop but it seems like a good chance for improvement in several ways. After my short test with a little more vibration, I would say you are heading in the absolute right direction. The action was so smooth, and so slow that it would never need a slurry thickener, but also so many vibrations in such a short time that it has to work. Looked like your video of thick sugar slurry, honestly. Maybe slower.
My worry is the length of abrasion would be too short for proper material removal/smoothing, but I seriously doubt that.
Excellent progress James

Thanks EricD, time will tell. One could probably contract the end plates of the motor to be an exact fit into the Lot-O mounting holes. The rest of the motor has about had to be set up for high production. Better if the shaft was the same size as the Lot-O motor so the fan could be switched over(probably best with smaller counters). That would certainly make the conversion easier.

Cool, I received the basic vibration analyzer. Anxious to see how this basic vibration meter works. It may require some translation/conversion to get a vibrations/second reading. It is possible rock vibes run on a 1/2 cycle of the motor rpm. Or some other divider. It will be the displacement and the acceleration that is the controlling factor. Acceleration at the reversals. My modified Vibrasonic is a gentle benchmark to compare to since it does glass with a minimum of media. The vibration meter can also be used on known values to figure out usage procedure and compare accuracy/readability. It is supplied with short(S) and long(L) measuring probes. Each with different characteristics. The short probe is for flat surfaces and yields most accurate info. It has been a while since using these charts. May need help with grammatical and technical interpretation anyone... $5 box of 2.5mm, 3mm, and 4mm SS metric short screws for adapting DC motors to washer flanges
