Battery drill rotary

[deny essex]

Have seen it asked on PW a few times in the past about using a battery drill for use on a rotary.

I came across this picture and several more in a disc browse about and thought it might be of interest to the rotary DIY'ers.

Parts are an old drill motor and body, a fishing tripod, aluminium and fibreglass composite arms.

A reasonable bit of glassfibre work was used , drill body wrapped in GRP and used to hold the body to the tripod to start (after wiring up),

A vehicle brake pipe nut was used to fit the motor thread (no idea what type of thread it was) a small female hex socket was welded to the top of the pipe nut.

Arms were a fixed length just under 4 foot (120cms) each, both connected to a small piece of channel bent in a V and pinned through as a pivot at each end.

A male hex shaft was welded to the centre of the V as a slot in to the motor female hex socket.

I made some glassfibre wings and attached them to the end of the arms and slotted shell decoys to slide over the wings as shown in the picture.

this allowed quick set up and break down, arms and tripod close up to fit in my fishing quiver.

The drill used was around 7.5 volt I think so no commercial speed controler was available, and in the interest of economy I used the drill trigger in a small plastic box with a bolt mounted on the box to depress the trigger as needed for the desired speed connected to a 6 volt acid battery.

I used it only for artificial decoys and hypaflaps when they came out.

Dependant on the drill motor used and battery it can be a little power consuming but nice and lightweight for an afternoon or short sessions.

Hope this was of interest (Boy I have too much time on my hands )

Great,the way forward is compact and light, brilliant idea and nicley done.I tend to leave mine in the truck unless its a short walk lol.I have been looking at using a 12v 300rpm motor same a I use on my homemade flappers for a lightweight rotary.Ebay item 141387536923,cracking motors on the flappers.

Cheers for your comments, I'm not sure the motor you are thinking of for a lightweight rotary will have enough torque against a light to medium wind, the rpm would need to be much slower than 300 to around 40 rpm, that would have more torque for sure but it would still be a suck it and see try.

But saying that I have made another rotary from a kids toy that runs my hypa flaps with no problem.

Good luck
