When I have the drums off the '51 (3600) I always adjust the brakes a bit before reinstalling the drums. If I've gone a bit too far with the adjustment the same thing happens when the two screws are tightened. Drums won't turn. The solution has always been back to the shoes off a bit.

Now the above is assuming all's right with everything as Jon covered.

Good Luck,
