mini machine

took awhile to make the needle work and had to cut it down smaller each time..also the support screw for the tube wouldnt tighten so i had to leave it out but the weight of the tube and needle pushing on it held it in place.also if u bend the needle down ward as abit it tends to help .no elastic needed as it is so small..turn down the pwer pack so that it runs fast but if its to fast it wont run with so much power.
all in all a kool little toy,,used it once and framed it.
