If you know someone with a 3D printer, I bet you could print a pile of them and be set for life...for next to nothing. I second this- I was just talking to a coworker last week in his office and it was filled with creations that his 16 year old son had been making on his 3D printer. Compared to some of the stuff his kid was creating I don't think a gear would be too difficult. Al ha, yeah, have a few printers around here. Gear teeth are usually tough to print with loads and without fancy filament. The problem here is the Gear was molded onto the shaft. flats also serve to keep the gear located along the shaft it that makes sense. You can see below, the teeth are not worn the gear usually cracks (from age)? So I had already printed these spacers to force the two halves to stay together. Could bolt them but just made them tight enough for a press fit, and not keen on drilling more holes in the original. Maybe add some adhesive. Time will tell. hmm don't see the upload photo link on this page..

yeah, HP I'm sure is importing them from China, be nice to find the direct link. If you meet a guy from Sedona again, let me know But still thanks for the tip, didn't know that replacement options existed!

20 odd years ago there was a surplus rush of these GE Mina Gear, Robbin & Myers geared electric motors from Xerox machines that folks turned into sphere machines. They're NLA. Anyway, the gear (nylon?) in the gear boxes tends to break after a while (I imagine grinding rock is a bit tougher than moving paper) . The gear looks like it was molded onto the output shaft, (two 90 degree opposing flats on the 1/2" shaft. and the gear tends to split. I'm wondering if anyone's attempted a repair or know of anyone that has.
Thanks.

DH printed a couple of these for me. I like them. If you guys know anyone with a 3d printer, you can find and download the files at www.thingiverse.com oregon has graciously uploaded them there. Tela Formsa seal of approval... that's something!

One day I'll run into someone who has a laser cutter and feels like playing with a new venture. hmmmm.

Not very many folks with the ability to print them out of plastic either Knowing exactly squat about 3D printing I wonder what the total cost per piece would work out to on that. At my former employer we cut a lot of polycarbonate sheets, the most common thickness being 10 mil, on our plotter cutters or even our laser cutters if the parts had features that were super thin. I don't know what the cost per sheet would be on those either - especially the lasercut when you factor in having to apply a masking on one side to reduce burning - but it still had to be a lot less expensive than 3D I would think. One day I'll run into someone who has a laser cutter and feels like playing with a new venture. I think it would only be a few dollars per sheet. Someone already listed some basic shapes, which DH downloaded. A quick calculation of that file suggests it would be like a dollar, but I'll say a few to be safe. yeah, show this weekend, just set up a room full of rough, buckets of slabs, extremely cheap, probably good to stay away... Give me the weekend or so. Cost in material for these would be very minimal, I don't cab much, but for just pencil/aluminum the PLA should hold up for a long time.

No Sorry to say my plotter or Vinyl cutter will not do that it can cut media 24" X 40' long. Single color or multi color overlay it will cut up to .25 mm. thick or 9 thousandths. You need something like a 3D Printer. to do that. Ahh damn, well thanks for checking.

April is a bit early; even June is often hit/miss around here. www.tripcheck.com (ODOT) would be good to bookmark. They have the road closures, NOAA forecasts for the various areas, and road cameras - so you can see if it's foggy on the coast and sunny in the mtns before driving! Areas have very different climates, east side/vs west, coast etc. It is often raining in the valley and sunny on the coast or mtns, and vice versa. Follow the 'best' weather if you can. April you might be able to hit the tulip fields near Woodburn, or the apple blossoms in the Hood River Valley. Old McKenzie pass will still be snowed under, if the drive to the rim of Crater Lake opens back up, I'd still put that on top of your list, 97 is a fine hwy down the east side, drops down to Weed without too much trouble. (Crater Lake's north entrance will also still be closed) so you'll have to enter from the south, Klamath Falls. Double check 101, as there was a major slip a few weeks back, and it was closed down south. But yeah, pull out a road map for Oregon, check out how many public access points there are, It gets tempting to stop frequently! I think in April you should be ok finding accommodations, gets tough during the summer months. Bring Warm clothes, you won't be happy if you need them and don't have them.

We don't want to burn up days rockhounding. Without a thought to rocks then, The southern coast is pretty spectacular, but the 101 is out a bit North of Brookings currently. The Central coast is also great, Coos Bay (Cape Arago), Great Sand Dunes, Florence to Newport have great headlands. The Coast range has some hidden gems, the Willamette valley heaps of espresso and brew pubs. The central Cascades (volcanoes) are pretty unique, St Helen's isn't that far North of Portland) Lots of lakes/rivers/campgrounds in the cascade range. If the old McKenzie Pass is open by the time you're here, that's certainly worth a drive. Bend/Sisters are likely to have nice weather all summer on that side of the cascades. The eastern side (high desert) has it's own beauty, (and Rocks) There are Rock Powwows in Madras & Prineville in early/mid summer. The Columbia Gorge is also worth a day, esp if you like waterfalls. In NE Oregon, are the Wallowa mtns, granite, spectacular... and in the SE Steens Mtn is another spectacular (remote) place; both of those mtn ranges are >9000'. And of course you should fit Crater lake NP on your tour, still a breath taker every time I walk up to the rim, hike down and jump in the lake! With our Winter storms, be warned that heaps of Forest Service roads are likely to have trees down for a while this year, and there have been slips on several routes that are closed. Also the snow pack will be an issue for hiking until late summer this year I imagine. I wish I would have taken a screen shot of the Crater Lake forecast a couple weeks back, it literally said: Saturday evening: Snow. Total accumulation 4 feet. (that was not a typo!) Have fun.

Though all the piles of snow aren't yet gone, the Sun is out! Just brushing off some of the club rock that will be for sale.... Springfield Thunderegg Rock ShowLaguna Lace, Graveyard Point, Ocean Jasper... Hmmm wonder what's in the other buckets?

I heard about that, real bummer. we have had two power outages in the last month but luckily they got it back on in a few hours. Assume you are set up to handle it and are staying warm.19 degrees hee this morning which is the lowest for the winter. Wood stove, and the first time I've actually gotten to use my generator for 18 years! (Wired in close to a main trunk) But driving around, I swear there were more power lines on the ground than still standing, just crazy. Glad it wasn't this cold all last week!

They will both polish up real good, I got to get a bunch more cut before it is time to go dig some more. Right now the beds are under a foot of snow. Just like the ones in my back yard, well they're under a foot and a half and a fallen Oak tree. But it's not like we've had power to cut them with for the last week either! ODOT said they had to clear almost a 1000 (thousand) trees between I5 and Oakridge on hwy 58, (~30 miles) Hwy was completely closed for 5 days... ready for spring!

My plug for Google Science Journal app sciencejournal.withgoogle.com/ there are IOS & Android versions. Kids can measure sound,light,temp, acceleration, and what ever other sensors your phone has in it. With a few clicks data is recorded to a google spreadsheet, and few more clicks to produce a graph. Incredibly useful as a grown up tool as well.

About anything you adjust is going to effect the vibration oregon . If you look a bit you may figure out the outcome. Moving pivot points, shifting the weight closer to the vibrator, etc. sometimes difficult to predict the outcome.. cleaning out the loto this morning, and wondered... I'm sure there are many apps, but if you have an android, Google Science Journal is hard to beat. Gives you quick access to all the sensors in your phone, spits out data to excel/google sheets as quick as you can tap a button. So I set my phone on the rubber barrel after I restarted this. Looks like the sample time is about 60ms, at 1500 rpm, the oscillation should be ~ 40ms... so not oversampled, but it gives you data, that I'm sure you could use to tune things. It's also the acceleration vector, so not amplitude perse, but should be related. Pretty cool with next to no work.. Maybe the sound data might change with frequency as well? I've used the light meter to measure rpms, magentometer,, xyz accelerations, sound, light... a data "tricorder"... You could sample better with an arduino and some cheap sensors/code, but for a solution you probably have in your pocket this is hard to beat. jamesp here's my loto vibe data, wo any work except selecting the two columns and hitting plot. phone sitting up right still for a few seconds recording then put on the barrel, then removed to hit stop. ( 9.8ms^2 at rest in Y, different after because the phone was tilted to press stop) have to play more, but thought you might get around to it quicker than me... have fun. [/quote]

I have an old lotto, the tuning dowel isn't glued down. Always thought that should be on a screw feed to adjust it back and forth. Imagine they tune it to sit on a node, but maybe you could dampen your lotto amplitude by moving that stick if you want to experiment?
