Hi,

 

Looking at rotarys and they are fairly expensive, before everyone says it, I know you get what you pay for but im a cheap ***. ive noticed some people saying make one, but... im not a very good handy man.

 

Can anybody point me in the right direction or give me some tips on making one?

 

cheers

You need some steel bar, steel rod, steel box section or tube, nuts and bolts, a car wiper motor, cable, battery, speed controller, tools and some welding ability..... I made one in the past because they were expensive, but you can buy them for next to nowt now. It's hardly worth messing about. For the time it takes to obtain the materials, design the rotary and make one, you might save £30.

I'm just in the process of starting to build one as well.

 

I'm going for the alloy version first, I hope it holds the weight of the woodies.

 

Opted for an electric car aerial motor assembly, and for the speed controller I

have an old 12v battery drill that I have dismantled, and I am using the trigger

mechanism ( and electronics ) which I am going to mount in a box and control

it with a screw thread hopefully.

 

I haven't got a clue what it's going to look or operate like but it's worth a try

all the same. If I had any pictures I would post them but I have only just begun,

as the Carpenters used to sing.

Seeing as no-one has bothered to reply, I will add another bit of text.

 

For anyone who is interested, or just trolls through and gleans information without

actually adding to threads, or anybody who just can't be bothered to reply........

 

I tested my home-built pigeon magnet thing this morning. Worked perfectly using

the light shell-type decoys. Whirring round, slowly blowing in the light/medium winds

I enticed a nosey woody into the catchment area. Let wang with the 12g and it duly

fell to the ground with a thud after spiralling helplessly in a downwards manner.

 

Anyways, I retrieved the pigeon and proudly placed it on the end of the rotary.

Little did I know that the centre of balance was shifted somewhat, I made haste

back to the cover of the hedge leaving the unbalanced rotary giving it big heave-o's.

 

About 3 minutes later I saw the two arms go into a spasmodic reaction as it collapsed

around itself.

 

Forensic examinations revealed that the weight of the "proper pigeon" had pulled the

nut heads straight through the epoxy filler that holds it to the motor. The filler was soft

and thats what caused the problems.

 

I will rebuild it with epoxy resin liquid this time as I think it will be a bit harder wearing.

 

And also, I will make sure that I have two proper pigeons on it to balance the weight.

 

Other than that, I am pretty chuffed at what I built. No need to reply, I will reply myself

later on because I use forums properly.

From what I gathered, HD, a real pigeon ( or a decoy with wings ) was the best option.

 

The only ones I have are the wingless shell type, and look a bit odd flying round in circles

without wings spread out.

 

I thought that at the time. Question being " If the spinning decoys are drawing them in - why

put a real one on it, could it be better ?"

 

But there we go, the design is flawed, it is not strong enough to hold heavy fatties and therefore

I will have to buy some foam/shell ones. Still, I am a bit miffed about that filler. I is at least an inch

thick and should easily be ample.

 

The resin I used to secure the gearwheel is rock-solid, therefore that is the way to go. I'll cast a new

base, and see how that goes.

 

Cheers

At last I sourced another motor/gearbox for my homemade pigeon magnet.

 

I tried to reconstruct the last one but had to give it a totalmakeover and the

time was out weighing practicality.

 

After a rumage in a skip, I salvaged a motor / gear assembly from a kids toy

truck and it looks the business, plus a 13Ah battery that looks ok but I will have

to test and be sure.

 

Will put some pictures if any one is interested. This thread seems to have died a death

since I came on.......

 

Trust me , I am a nice person really :)

 

 

Regards

Try using some real pigeon wings with a couple of wooden skewers pushed through the hollow bones of the wings, then skewer them through the body of the shell deaks, then cut a piece of wood shaped to the underside of the deak, & staple it through the lower part of the wings & deak, this stops the wings from spinning round & holds them firm in a realistic position. Drill a hole the size of your rod arms in the wood.

 

I've not tried these on a rotary but I'm sure you could modify it to work. I use mine as a floater.

 

See some pics in the craft & DIY section

Could do SS, I might just buy a couple of the polystyrene deeks and stick them on.

 

I'm still building the motor assembly. Came across a a couple of things I havent got

and have to aquire them.

 

Keeps me happy for now knowing I could save £50 or more.

 

Always a bonus saving money if possible.

 

Regards
