SAlem sucks sewer water.. All sort of heavy equipment is repaired here.. Do you think I can find two 1/2 rod end clevase? Closet good farm store is 20 mie away.. That's 40 round trip.. Where do I go to kill some one?

Try MSC?

Not to kill, but find the clevis'.

Here they are listed as Rod Ends

Here's a1/2" one with threaded stud

There are the three fine-thread bolt holes (used for pulling the balancer) that I can use to bolt something over the existing balancer/drive pulley.
So I gotta figure out a slick way to make a bigger drive pulley, for a flat, wide, grooved serpentine style belt.
What would you do?

1) Whats the bolt circle for the bolt holes?
On the design side we only need so much material left after the threads.

I would measure those threaded holes to make sure the are on center. Since they are usually only used for the puller they may not be dead on. You know what they say.. if its not on the print it doesnt matter and they go by the gd&t in the corner. No matter what you do you want to be balanced. So if possible I would try to turn down the first pulley so I could mount the new one on top. Sucks that you cant get access to a bigger lathe.. hope you get it sorted.

Are you sure you can't just snag something from the vendors? There is an awful lot available.. if you can find it in the gigantic catalogs.

McGuire bearing has a store in Salem. I think they might call them Heim(sp?) joints though. I know the Portland store has them so it must be possible to get them in Salem.

I hope this helps.

There are dust caps made for ends too.
They say the teflon coated keeps dirt out.
They have some specialty with large bearings for the size of the thread.

McGuire's is getting to be a lot like going to Radio Skack.. There rod ends are closed and would bind for my use.. That one smug bastard there is the one for me to take out my grump on..

The rod end I need are threaded to the rod and open clevis for a pin.. Like you find on a truck break linkage or a farm machine lever and rod linkage..

That's the sort of thing we trip over in every hardware store -- until we need one. How about just welding two scraps of flat stock to a barrel nut?

Shop Cat and were just having coffee.. Why not use the new bending machine and make my own?
Duh! it will be 75% lighter and made out of scrap for cheap.. Nuts back to back will save welding..

It hit me last night as I was going to sleep that I'd pointed out the wrong type or rod end. You typed clevis, I typed clevs, and I still went and found a ball type one.

Here's what I was really thinking of:

But I've made them too, since I often didn't feel like waiting on UPS or banging my head on the local hardware store wall. Bent flat and two nuts work great!!

Use bronze as a bearing if you have it.

A week of playa dust against steel will work fine.. After all it's a contraption of my sick mind.. Do not want to get to fancy

MozyBonz · Post by **MozyBonz** » Sun Jul 27, 2008 9:53 am

Since the fancy five-grooved drive pulley is pressed on around the balancer, separated by a rubber ring,

Are you saying that yor are going to not have the rubber ring at all?

Wikipedia wrote: The damper is composed of two elements: a mass and an energy dissipating element. The mass resists the acceleration of the vibration and the energy dissipating (rubber/clutch/fluid) element absorbs the vibrations.

Maybe using a different balancer so the pulley is not part of the balancer.
that would give you a wider range of options in pulleys.

I was just gonna separate some extras to make a bigger pulley, then mount that over the intact original balancer, complete with it's original smaller pulley.

After extensive wrecking yard searching yesterday, I found larger exactly correct pulleys on early-90s S-10 Blazers. It even mounts to the three threaded puller holes I was going to use... I just need to cut the center out and reverse it, like the old hot rodders did to their stock steel wheels, to make the pulley sit tight against the motor instead of sticking way out like it did on the S-10. Hopefully it fits on my friend's lathe so I can cut it perfectly concentrically. Problem solved for $3.50 and some cuttin' and weldin', as is proper for a BM mutant.

Gotta save the $$ for gas and tequila!

See there right off the shelf...just right for your use. I knew you didn't need to reinvent the wheel.

Congrats! I'll be expecting a nice cold gas-n-tequila on the playa.

(I don't know if that's funny or not. Have to try.)

Right on Unjon! You and me are on the same page but I went to the hardware store and dropped 70 bucks on stuff. Once I got home and looked at it again I decided that wouldn't work and built the shift linkage out of scrap and what I had lying around. Now do I waste gas getting my money back or just hang on to the extras for the next decade?

Half the crap I have is from trips like that one. I'd probably hang onto it if it didn't interfere with food or bills. The entire hook up of the old engine to the contraption was accomplish with parts from previous stuff like that. Thanks to that, the only purchase (besides the engine of course) was a $6 bushing for the sheave on the crankshaft.

Extra parts=future self-reliance.

And on the contraptioneering side of things around here, this is where its at as of tonight. Still gotta work on the smokestack and some other minor additions, but it moves under it own power!

unjonharley · Post by **unjonharley** » Sun Jul 27, 2008 8:05 pm

Awhile back one of the vidio store return boxes was broken into.. It's bent so the door would not close.. So a new one replaced it.. The garbage truck refuse to take it. So I hualed it home..

A little action with a bottle jack and wood blocks fixed it.. There it sits in the back yard full of buckets of "stuff".. I am ashamed of myself for going out to buy more "stuff"..

This winter I hope to make the box into a boiler room to heathe shop area... With the area heated I can dump the buckets and try to remeber what I see..

Mind you, I did not say" throw anything out.. I'll just try to put some moey with my will for a good dump run..

AHH,LCN I do like that bit of rust you have in your yard tonight.

Could you add some pullies and belts, that go nowhere just to punk it up a bit¿¿

That's a great video, LCN !
It doesn't quite show how cool it is to be standing in front of it, and see the headlights shake along with the engine...

How fun it is to have it running, tonight ! ! !

Sadly, there is no emoticon for me squeeling like a little girl at a Hanna Montana concert...

Or maybe that's a good thing?

Looks and sounds AWESOME LCN!
Glad you liked the pic to.
