Front mount distributor - gap too tight

1949 8N. New set of BLUE STREAK points. Whenever I tighten hold-down screws (mostly the screw below the points) gap becomes too tight (real tight). I don't notice play in the shaft so I don't think bearing worn. Old points were cheapee TSC ones and were a snap to get in and set year ago. These new ones were a bear to get installed. What am I doing wrong? Also, had to "farmerize" new copper condensor strap from old set of points as existing strap was only attached by a micron of copper, but I don't think this is why point gap is difficult to set...or izzit?

Should read "years ago" not "year ago". Been a long time since I replaced points, wayy over a year. Typo.
 
dig out the rat tail file and get after a hole. Yeah, I know, you shouldn't have to, but if you had, you would be done by now.
 
Thanks Jmor, but all the 10,000 posts I read prior to this one said NOT to file points as they will need filed every time it needs to be started once the surface is buggered up. I should add they don't line up correctly with each other once tightened.

OT file contacts! Make mounting and adj holes oval as needed to obtain proper gap. Bend to align.
 
"Whenever I tighten hold-down screws (mostly the screw below the points) gap becomes too tight (real tight)."

One of the big problems I've encountered with today's new points is that the tab on the points that rubs against the cam on the distributor shaft is too short. I've encountered several sets of points that the tab was so short the points would not even open to the specified gap. If this is your problem JMOR suggestion to file the slot should help.

Or, do you mean you can set the gap, and then they close when you tighten the lock down screws? If so, determine the difference in gap when tightened, add that difference to initial setting, and then see if gap is correct when you tighten them down.
 
It is exactly the second case where it closes up when tightening the lock screws. The problem is that I start with the widest gap setting, which is still a bit tight. Going to try JMOR's suggestion when I get back out to the shop.
