[Rockhounds] Dead rock saw

[R. Peter Richards]

My old Highland Park model E4 rock saw finally bit the dust.  The  
bearings seized up.  I managed to get the shaft block off the box,  
but can't seem to take it apart.  Not sure I could replace the  
bearings anyway....

Anyone have a spare shaft block to sell?  A spare saw?  Do I have any  
other options?

Thanks,
