Hello.

The winding machine wraps 15mm kraft balls with glue.

The tensioner is installed on the wheel , which allows you to wrap balls with the same kraft tension.

To fix the ball, use holders (crowns) for balls 2,3,4,5,6,8 "(6 pieces), with a length adjustment to change the diameter of the winding of one of the poles, if you use 2 fuses.

Starts for my birthday.

Stinger worked only one of the light launch pad. When it started, it fell and the stinger went on the ground.

2 " shells 56 grams of weight worked out regularly (the stars are all old)

3 " with a weight of 170 grams (one shell crushed the old stars)

4 " mass of 460 grams worked well, only flew away very much (above was 6.5% of the mass of the ball)
