Tillering Tree Question

[Bowjunkie]

If you can't find them locally, you can get the pulleys and bearings on ****... I got the smallest pulleys I could with a 1/2" center hole so they would clear the wall without having to make pedestals for the bearings.

I didn't grind flats on the shaft, just tightened the allens, and they hold well, even on the hardened drill rod.

"****" means the big auction site.

thanks fellas. I'll be going after parts tomorrow. be nice to have a good pulley system after all these years.

Roy, did you have to bolt to the floor for clearance for the pulley?

[Roy from Pa]

Yes. The pillow blocks sure make a smooth system. This is the top pulley with like a long U shaped mount on top, top pulley has ball bearings in it.

If tillering is great exercise, you will fatigue from tillering, especially if you spend most of the day or most of a couple of days doing it.  I have a bad lower back. Tillering is not an issue on its own, but it is an issue when mixed with other activities.

what do you use four pulleys for? I can see two, on for split finger, one for three under holds.[/b]

His setup has 2 for right handed bows and 2 for lefties.  There's a pic in this thread:  http://tradgang.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=125;t=012442;p=3

On the subject of pulleys, for some reason, the hardware stores around here have horrible pulleys.

Home depot:
The pulleys where not straight in any way shape or form.  The pins where in crooked on a lot of them, and the grooves for the rope where not centered or straight.  This means you'll have problems with the rope sliding off the pulley.  Just pure junk.

Ace hardware:
It says right on their pulleys that they are not rated to be used for lifting a load.  I.E. they are not real pulleys.

Lowes:
Their pulleys seemed fine, except most of them have a problem with there being a big casting seam on the wheel which will make it chew through ropes.  I opted for these as the lesser of evils, and just ground the seams smooth myself.

I have yet to check Mernards though.

So wtf?  Where can you even get decent pulleys these days?  Someone mentioned sailing shops, but there's not much call for those for us land locked state people.

Not for left or right handed bows, Colonel... just so I can flip the bow around and view it from the other side.

[Bowjunkie]

Those pulleys of mine, the ones in the picture in the thread you posted the link to, also had a couple of casting ridges that I had to clean up.

ColonelSandersLite my fatigue is from lower back pain as well. I have three herniated disks in my lower back and find the two pulley system easier to use after working all day. I bought 2 inch pulleys from ACE hardware and haven't had any problems.

My two pulley set up is similar to Roy's. I set it up based on the instructions Terry Green posted here on TradGang under the Topic: How to Make a Tiller Tree - (Jeff Sheyn). You should be able to find it under Topic Archives >> How to - Resources >> How to Make a Tiller Tree - (Jeff Sheyn)

You too huh?  I was tillering today.  First time with that pulley I mentioned (I haven't done a 2 pulley setup yet).  At first, everything was fine.  After a little while, it started squeaking.  Then it started more screeching with every pull.  I took it apart and found out that they didn't even bother lubricating the dang thing at all except *maybe* a very light coating of wd-40 or something similar...  Fortunately, I had some automotive bearing grease sitting around that quieted it down.  What a pain in the ass though.  So seriously, wtf is it with pulleys these days?

Oops  :p .

@Robyn Hode
Good to know it helps your back out.  I'll definitely have to try it out on my next bow then.  Won't get the chance on this one though.  That basic layout is what I was thinking of as well.  Here's the actual link for the convenience of anybody that reads this thread.  http://tradgang.com/noncgi/ultimatebb.php?ubb=get_topic;f=2;t=000016

As for ACE's pulleys, either your particular store is carrying some better stuff than mine or it's not rated for lifting.  Even though the stuff I saw would probably work, I'm just not willing to buy from a company that won't stand by their product even a little bit.  It's like buying a bow from a bowyer that says their bow is not rated to shoot arrows.  Just...  No...

Google Petzl climbing pulleys

My top pulley with the bearings in it is for a garage door cable. It's well constructed. My lower pulley is one that slides onto the shaft of an electric motor.
