Calipers Calipers Everywhere

We have a daily community errand runner, here at Acorn.  Sending out one person in one car to get the half dozen things that we need from town saves a lot of time and gas and cuts down on the number of cars that the community needs to keep to function efficiently.  Today I was that person.

I’m also one of a small number of folks who look after the machinery here.  Today the errands were unusually machine focused as I had been saving up errands that required my special attention for a week or two.  I discovered that a good metric of how mechanically inclined one’s basket of errands is is the proportion of stops that result in the person I’m visiting pulling out their “mics” or high precision calipers.  Today that was three stops out of six (the library, post office, and hardware store had no desire to measure anything I was bringing them).

There’s a lot happening here in the world of machines.  We’re upgrading our tractor capacity now that we have the labor and money to do it.  We finally bought a used John Deere 1520 a couple months ago.  Hailing from the 1970’s and weighing in at about 46 HP it’s a big step up from our vintage 1938 Ford 9N with it’s 24 HP.  Plus, it has a front end loader.  As River predicted, once you have a front end loader you look at the farm in an entirely new way.

The three errands today all stemmed from the purchase of the tofuier tractor (thanks to my friend Pax for finding a vegan friendly alternative to “beefier”).  The bigger tractor has the ability to run a mower conditioner which means that we can start haying our own fields.  This means that it made sense for us to get a hay rake and a pair of pallet forks (which can double as hay bale lifting forks) at an auction recently.  As with many things purchased at auction, the upfront cost is low but the amount of money you’ll have to sink into someone else’s junk to make it work is unknown.

On the way home, one of the universal joints on the drive train for the hay rake shattered.  It was quite the ordeal dragging the whole thing the remaining 15 miles home.  The project now is finding a replacement for the shattered yoke.  The discovery, sadly, seems to be that the u-joint in question is ancient and idiosyncratic.  Dickie, of Louisa Auto Parts, says it’s of a size that simply isn’t available any more.  We’ll have to chop the whole thing off and substitute a newer model.  One caliper usage down.

When we got the forks home from the auction we discovered that the pins for the forks were a few fractions of an inch smaller than the holes in the front end loader.  Now the project is finding bushings or reaming out the holes on the fork so that the front end loader’s pins can fit.  I brought a sample pin off the forks to Dick Harris, the machinist in town, for him to puzzle on.  Second caliper usage down.

Now that we’ve got a big tractor we can finally run our tractor mounted back hoe again.  Our previous big tractor died some 6 years ago and we didn’t have the money or skill to repair it or replace it until this year (I’ve been training myself for the last few years and finally started figuring out the rusting behemoth in the tractor lot last spring).  So last week I pulled the tarp back from the poor neglected backhoe, dug out the accumulated humus from years of rotted leaves, and hit all the joints I could find with penetrating oil.  Miraculously, all the valves look to be in great shape.  Sadly, the hydraulic lines supplying the PTO mounted pump had sprung leaks and the adapter that affixes the pump to the tractor’s PTO shaft had rusted half to dust.  I got the pump off and with the help of plenty of penetrating oil and a bearing puller managed to separate the pump and the adapter.  Then it was in to the local backhoe dealer to get a replacement adapter and some advice on the pump and backhoe.  We needed a new key to affix the adapter to the rusted pump drive shaft.  But what size was the key supposed to be?  Third caliper usage down.

In a week I expect us to be fully functional in tractor land.

I hope I didn’t bore you.  Joan told me to just go ahead and write what I know.

  1. Good post. I like it.

  2. no boredom, a few grins, and much education…thanks. peace.

  3. It’s fun owning machinery…especially the old variety…:-) Have been there and done that for a good many years. Just remember…don’t push the old stuff too hard and it will last a long time…if you baby it. Franklin

  4. I guess that’s why most farmers I know have sheds full of “junk” , and tools for altering the bits to make them fit. You never know when you might need something, and it’s too far or takes too long to get someone else to do it.

  5. I love virginia. That sounds like a cool place!

  6. I would love to go there.

  7. wow it sounds great

  8. Cool post, Gpaul. I like technical tractor detail.
