Stringing aluminum racquet

#1
I enjoy playing with a Weed 135 head size aluminum racquet strung at 64 lbs. The problem is after stringing the mains, the head deforms noticeably. When I finish the crosses it bends back to original shape but all the bending can't be good for the aluminum. Any tips to prevent the deforming? I'm using a Gamma Progression 2.

Google 'weed tennis stringing instructions' You have to slack off tension for the last 3 outer mains.

Query-I thought Weed frames were graphite? Alu frames, once deformed, do not go back to their original shape easily. If you squash the head doing the mains, it means you did not push the 6/12 supports out far enough. When you did the crosses, you were lucky they pulled the frame back into shape.

The Weed instructions for standard/conventional stringing specify a progressive 5 pound drop for the three outer mains (left and right) AND for the three outer crosses (top and bottom) and state reference tension should be the same for both mains and crosses.

Example of conventional stringing for the Weed 135 18x21:
With mains counted inside out - M1 to M6 @ ref tension, M7 @ ref tension minus 5#, M8 @ ref tension minus 10#, M9 @ ref tension minus 15#.

With crosses counted top down - C1 and C21 @ ref tension minus 15#, C2 and C20 @ ref tension minus 10#, C3 and C19 @ ref tension minus 5#, C4 to C18 @ ref tension.

Note: This is NOT the "Live Periphery" or "LP" method with the two outer mains and crosses using boxes with a different string.

The Weed 1 came out around 1978 so my Weed 2 must be early 80's. I have a graphite Weed but actually like this old aluminum one better. It is the ideal combination of big head, low power flexy frame, 16mm beam, headlight, 12.5 oz, standard length. Newer graphite ones are too stiff, too wide, too light and too long and too head heavy.

Next time I string I am going to try using a turnbuckle attached across the width to prevent distortion.

Normal don’t try to keep that deformation from happening. As long as your rackets end up in the correct shape you’re fine.

Don't know about Weed aluminums, but instructions for the Prince aluminum racquets included advice to stretch them somewhat when mounting. On an Ektelon H this meant pulling on the throat riser before securing it to elongate the racquet head with the 6 and 12 supports.

Someone use to make a large "U bolt" with pads on it it to do what I'm guessing a turnbuckle does. Even before that, I used a leather belt that had holes all the way around it to keep Prince aluminum frames from deforming. I'd put them in the middle of the racket, then slide them off towards the handle as I got that far down with the cross strings. Worked like a charm.
