I have been getting some PMs about these and thought it would be a good idea to start a thread that could possibly be "Pinned" to the Massey forum so all can see.  I think Kenny can handle that for me.

 

Here we Go!

several years ago I decided I was going to find a way to make these hard to come by pulleys.  I contacted my local bearing supplier "Werner" and asked them if they could find a supplier of the raw stock with 41 teeth so we can keep the stock belt.  They found a supplier and it required a $600.00 minimum order.  I bit the bullet and ordered 3 sticks to make the minimum.Raw Material.jpg

From there i used my bothers lathe on the weekends and came up with this.

Semi Finished Pulley.jpg

The Broaching was done by a friend of my bother that purchased the broach and did 2 pulleys as a trial.

The Broaching is perfect and I used those 2 on a deck and that is where the project got left at about 2 years ago.

 

I am going to revive the project if there is some interest in these pulleys.  They will not be cheap but I do not need to get rich off them ether.  I guesstamet would be in the $60 to $70 dollar range.  You would have to reuse the outer shield from you old pulleys and mount them.  I remember Parts Tree had some old stock single (outer) and was getting $72.00 I believe. 

As this goes on I think I will make my own shields and sell the pulley complete.

Ducky, thanks for putting forth the effort to have these made. Sure looks like they turned out perfectly. I just might have to be your first customer! Thanks

Looks good Ducky. At first sight I thought you had 3d printed them. Are these plastic or are they the original composite material? Wonder how well plastic would hold up?

I forgot what plastic they recommend but it is suppose to stand up to the application.

No 3D here. Was purchased as solid stock.

I was able to connect the guy that did the broaching of the splines and he no long does that.

This spline is 9 tooth 10/20 which I believe is the DP (Diametrical Pitch) The shop also added (30 degrees)  to the specs.

See attached. Below.

 

I plan on calling a few companies that make broaches and see what I get back.  This is plastic so I am hoping to be able to do this in my press.

 

Any of you engineering guy out there that understand how this is all done please chime in.  This spline stuff is not my best subject.

Would 30° be the PA (Pressure Angle) of the gear? 

 

I found this online just doing a little searching, 10/20 is shown as DP which you figured, and 9T.

Guys I just did some research and I believe I can make my own broach but I need you Help.

I anyone has some old shaft from the mower deck that are bad because of bearing damage or what ever but still have good spline and can send then to me you will get a free pulley. I think I can do this with 2  of the long spline shafts.

What my plan is to machine the OD of the spline to to progressively smaller diameters and stack this together to build a broach. The spacers would be the OD. of the ID. of the spline.  This would keep the broach in alignment and a space for the shavings as it is push though the socket.  We are only cutting plastic so I believe the steel will cut quite a few pulleys before I will have to sharpen it.

 

If you see any thing I have over looked please chime in.

Any subscriber to this site will get them at cost.  If I do not have to spend a ton of money on a store bought broach I can keep the $70 piece on this run.  I will have to see how the price changes for more pulley stock.

Together I think we can make this work.

Don, I may have what you need, but give me a day to dig.  If I have them, they're yours no strings attached.

I have two short and one long shaft. But they are NOS. I’d like to keep these as backups but If no one else is able to provide some used ones these would be an option. I’m with you on using ones that are shot instead of ones that are still in usable condition.

Thanks for your offer but before I would cut up new one I would try to find used one.  Those shafts are quite valuable themselves.

Let wait a bit and see if any bad shafts show up.

Did a quick search and came across these guys, a lathe is required for rotary broaches

My only concern about using a old shaft is keeping aliment straight when pressing the shaft thru the nylon block, and looks like fun shaping and sharping them

there are spline broaches on ebay but they run around the 1000 dollar mark
