Wolv,

Are those blades the factory made, molded plastic type?
Or the type like PVC / ABS pipe?

These appear very much like factory made. TomW will know more of the particulars.

That's all I needed.  I know what they are.

(there were some concerns emailed to me about the mounting and the trailing edges, but it's all good the way you have it)

Any and all input is welcome.

These are bolted through, not screwed in, just in case anyone is wondering.

What is the concern about the trailing edges?

I'm still thinking I will makes a metal frame that matches the bolt holes and then reverse the blades on the wood so they will be backed on metal which attaches to the hub and have the wooden front. Possibly make a fancy pointed end even.

I don't think they are mounted on the hub right , those tabs 
should be bolted onto the hub at angle of about 22 degrees ....just
guessing , so facing the mill it would be going clockwise....the way
you have it now it would be going counter-clockwise....seems that
ever one I've read about the root of the blade is at a good bit of an
angle and the tips are almost 0 degrees.

I may be wrong but hope someone sets us straight cause I got a set
just like that .....got 'em from Tom also.

Norm.
BTW ....have you found those cordless drill paks that you want the cells
replaced on ?

I made some time to figure out the mystery of the grinding TDM from TomW

Tom had mentioned he thought this had bad bearings, but ever since I got this I had a nagging feeling I have felt this kind of drag before. I had initially thought maybe it was brushes, but yesterday I found out.





This sounded/felt familiar because I had this very same thing happen on a treadmill motor I played with years ago.
Seems the bearings are fine, but to re-glue the mags presents me with a question.

Minnesota has very extreme temperature changes,( very fast at times)

I had fixed that treadmill motor once with JB weld, and it worked at least into one winter, but in use AS a motor.
Today I checked and the very same magnet is loose in that motor, its been almost 8 years however.
I have also used JB weld to fix severe pitting and damage in an ATV carb. This worked wondrous until winter. It seems the aluminum flexes to much with temperatures to hold up, I had nothing but JB weld dust and chips left when I took it apart.

So anyone have suggestions on what I can use to put this together? Winter is right around the corner here, I would hate for it to fail really early on.

It might sound stupid, but it's a genuine suggestion. Have you looked at *tile adhesive*?
Here's one we use: http://www.dunlopdiy.com/trade_resaflex.html

This stuff is incredibly strong/sticky but also retains some flex. Might be worth some investigation?

Yeah this seems like a great suggestion. Ross thank you
It might be a few days before I get to this again so I'll wait o see if any more suggestions are made before making a final call.

The factory adhesive may have had a bit of flex when new... but those motors are 3 decades old now.
