I have an opportunity to buy a heavy 10 collet draw bar but unsure if it will fit my 1947 1-7/8" spindle. Are they made interchangeable??
 
The heavy 10 (5C) drawbar will not even go into a 1-7/8-8 spindle bore. IIRC a 5C drawbar is "about" 1-3/8 inch OD. The spindle bore on a 1-7/8-8 spindle is "about" 1-1/16 inch ID. So you couldn't even get the drawbar inside your spindle.
