Here is a shot during mockup stage. The "flywheel" is a 50 pound barbell weight from Academy.
The shaft is standard 1" gokart axle I had laying around that was chopped down to make idler and crank shafts.
The hole in the weight was 1-1/16 and not well centered so I chucked it in lathe and centered/cleaned it out to 1-1/8 and used shim to center on 1" axle. I used a gokart hub keyed to shaft on each side for support and ease of mounting.
The flywheel took most of the shake out of the machine and it runs amazingly smooth.
Shot of other side showing crank assembly.
It's another gokart hub keyed and welded to shaft with a 3/4" bolt set at 1" offset for 2" total stroke.
The table swings from top suspended on 12" links and the double belt reduction gives 112.5 strokes per minute with motor running at 1800RPM.
The small pulleys are 3" and large are 12" and I use a simple cam-over lever to tighten belt and engage the shaker.
The original heim joint on crank is still alive after 10 months of hard use - we have a pillow block to replace it but it's still working so...just lube it!
Video of test run #3.

Re: Show us what you welded today!
Got some pics of Monday's project. Rusted out vertical pivot pipe. Of course it's a custom fit thing. Pretty easy though, got all the wiring out of the way today, pick up parts monday morning and get to it.

Looks like somebody already did.
An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.

The guys will come back in 10 years and wonder why your part looks like brand new,, and everything else got older,,
It's been tried. Not much difference. this pipe is in the 20 year old range, which isn't bad for the application considering the chemicals they pump through the systems.

Re: Show us what you welded today
I helped my neighbor weld some plates on the bottom of his air compressor tank legs today so he could bolt wheels on it. Sorry i didn't have a phone so no pictures. I'm not sure i want you guys seeing my welds anyway, although they are not bad for a amateur

Re: Show us what you welded today
JB weld is great for repair industry. You see JB weld now what charge goes up.
QUOTE
1) remove JB weld
2) clean where JB weld was.
3) smell from cleaning JB weld off the part.
4) use welding to do job right
Now a happy customer 😀 with job done right.
You happy for big pay day.

Dave, there is nothing left to weld to. Replacement of the pipe is the only fix. I didn't get to that one today, it rained and the wind blew pretty hard. No crop in the field so not a big rush.

Re: Show us what you welded today
I kid you not... I was in the local garage yesterday and there was an electrician's work van on the hoist. The brake line had been repaired with JB Weld.... so there, enough with the farmer fix jokes from you sparky guys!

Got out from the truck repairs today and got the pivot riser pipe chopped out and the new one installed. 3 hours onsite.

Yup, it will probably do a couple more revolutions to get some moisture in before winter, and maybe some liquid cow poo for fertilizer and draw the lagoon down at the dairy. These guys have 2 different pipeline systems for both.

My friend used to grow turf near Spokane. I think he got his water from the Alcan settling ponds that were waste water from cooling during production I believe ?

Alcan, or Alcoa, Alcoa had a rolling mill out on Trent avenue that used a ton of cooling water. I do seem to remember a turf farm out that way.

Yes. Probably Alcoa. I think it was their land too. He had to knock down all the sand dunes I think. Long time ago....
