Turning Target Project-Part 1
As a bullseye shooter, it’s rough to try and ‘really’ improve on the short-line without practicing on an actual turning target. There’s a few out there a person can purchase, but the ones I usually see run about $1300 – and that’s just not cash I’ve got lying around. After some searching on the net, quite some time ago, I found some instructions on a DIY target; Ed’s Turner. It turned out it was a guy I actually know…it’s a small net, ha! Unfortunately for me, I don’t speak ‘electronics’–well not to that degree–so the undertaking was a little rough. No knock on him, that’s his thing–but I needed ‘Electronics for Dummies; Volume 2 – Dumber’n'a bag of hair’…but the store was out. That and his design called for a specific motor – which I had a heckuva time trying to find. Eventually I found one that he helped me work with and I got all of his guts working–all clamped on my desk, ha! Finally – his design called for the electronics and motor to be mounted beneath the target holder…that gave me the willies. Now, I won’t go so far as to say I ‘suck’ at bullseye, but Lord knows I still have a jerk or a flier now and again. The thought of possibly shooting my own motor didn’t sit well with me. I was looking to have the motor and guts near the ground – like the ones you can buy. The up side to all of that was that I learned A LOT about the inner workings, courtesy of Google and my ability to use a search engine, hehe. But I’ve since scrapped trying to build his design and have gone a route that I think is a lot easier.
So far, I’m into the electronics stuff for only about $40 and the wiper motor for $16…roughly. So, $56 and some stuff I had lying around has gotten me to this point. I’m planning on doing a full list and guide when I’m done so y’all can just copy what I’ve got goin’ on – if you want. I decided I was going to build it in an M249 ammo can – I’m seeing that there might be some structural issues with the side flexing when the thing is turning – but as of now, the motor torques like a champ! For the record – the can will be on it’s side when operating, despite the fact that I have it upright in the pictures.
The wiring design is actually pretty simple if you take the time to understand what everything does – the up side, you can use any motor. You’ll just have to determine the low-speed and high-speed connections, since that’s all you need to hook up (on my diagram, the ‘+’ is high and the ‘-’ is low, but that doesn’t even matter).
The stopping at face/edge is controlled by a roller switch – so it doesn’t matter what contacts are being made within the guts of the motor itself. However, since I had the one I started with – I used that, and it works just fine. Nonetheless, I’m not a ‘wiring’ guy – so my diagram is very low-brow…which is why most will probably understand it, ha!
All I’ve got left for the electronics is mounting the roller switch, but to do that I’ve got to get the linkage to see how the target will turn and where it needs to stop. So that’s just dangling right now – just like the kill/speed-toggle. I’ve wired in a toggle to give me the option of a faster turn – but once I decide which turn speed is best, I’ll remove the option from the toggle and made it a simple “off” switch so you’re not using power when you’re not using the target. The linkage will consist of some pillow blocks and a shaft (google ‘pillow blocks’ – my buddy had to tell me the right term) connected through rod-end-bearing-thingy’s to the motor…still workin on the right names for that stuff, ha! All that aside, I’ll probably be done soon – well; soon relative to the project. We’ve got Interservice in a couple weeks, so I dunno if I’ll be laying down the $$ until I get back. It looks like the stuff I need to finish up is gonna run about $200 (high estimate). Suffice it to say – $256 is better than $1300.
More to come…
