In 30 Minutes I had mine done!
First of all :
BE REALLY CAREFULL IN EVERY WAY IF YOU ARE GOING TO TRY IT
I wonīt take any responsibility for injury.
All you need is a regular fan, but you need to take out the security panels.
Then you need a regular wood stick and to cut some leather belt that you donīt need anymore and with a shape you think will feel good in the spanking.
Attach the belt "well" , I still dont know how, I used some rubber bands, but I think glue or wire is better.
Then the hard part is to attach the stick to the fan, I also used rubber bands that they were not good, you have to find out the best think to put something that you can remove after the spanking session (without anyone notice that is your new loving spanking machine)
Then take care with the following things:
TAKE CARE NOT TO CUT YOURSELF WITH THE FAN!!!! (mine is really old and donīt have much power, also the spanking wasnīt that painfull )
Also maybe you would have to tilt the fan downwards a little bit, it depence on the fan... also try to build a safe base for your fan... (you donīt want the fan to fall over you)
Then if everything is ok... just take out your underwear and enjoy... or use it with the naughty person you love.
This is just an ordinary design... I`m really looking forwards for you to improve it!! and please share it with me.
