First pic is a reducer for the bottom pulley so I can use a woodruff key to anchor it. 

Second is a key way cut with 3 stacked cut off wheels for the upper pulley.

Third. Here it is just slid together

Happy Thanksgiving. Be safe everyone

You too, Frosty!

This is what the exhaust pipe was used for. It's a 2 part sleeve, top/ bottom to press the bearings against. I decided to use 3 bearings. I was thinking there might be some flexing in the middle of the shaft. It should be together and installed shortly.

Assembly is looking good.

Thanks. I had a mishap thou. Someone drilled some holes on the wrong place which made the drive unit out of square. Just had to weld in 5 holes, re-drill, re-tap.

Elves with drills. Go figure.

They sure aren't the shoe makers elves cause these ones aren't helping me one bit.

With the unit off I took the opportunity to start some linkage work with a couple bellcranks.

Mightta been some o those Faeries too. 

They can be real rabble-rousers. So I'm told.

Getting an early start. One linkage rod ready. Some riding mower tie rod ends should work nicely.

I'm really enjoying this!

Some more linkage work. Added some dampeners as well. They were also on the zero turn. They really take the herky -jerkiness out of the controls.

“Herky jerky controls are the best!” Said no screw driver ever...

Herky jerky may be the difference between rite side up or wrong side down 😄😄

Belt guard assembled and installed. Even shortened the vent hoses. Started a little work on the dash area as well. Looks like Tuesday is a rain day for me, so maybe I can get the engine tuned up and installed. I would like to test run everything before I start on the screw units.

Getting close to the point of ordering chain and tensioners. I'm having a hard time deciding which style to go with. Spring loaded? Ridged but slide adjustable?  Floating? Then the decision of sprocket or roller. Any input?

[ebinmaine 67,420]

Without wasting a ton of your time.... What are the ups and downs of each?

 

 

 

 

Yes I'm upta something....

Good question. I'm not really sure

Gets my vote

For the amount of run time this will have, I doubt you will even ever need to adjust them but it's nice to have the ability to easily do it if need be. Plus any spring or floating tension will allow that side of the chain loop to move under load and possibly slack the other side since the load on the chain will change from each side of the loop with forward and reverse.

Idler sprocket

3

Or just a chain loop directly on the drive and driven sprockets without anything else

Very good point. I wasn't thinking of the reverse aspect
