Trommel Build

[JDH429]

Had started drawing something up a while ago and just got some time a few weeks ago to start making some parts for a drum screen.














and then skip way ahead...I didnt take any pictures during this time as i was in high speed production mode..
















I have a few different speed motors im going to try once it is operational. The 51 rpm gear motor shown turns at a nice scale speed but might be a bit too slow...will see.











If i ever get my junk up and running i needed a purpose besides just digging holes in the ground, So i also started piling up some dirt to have somewhere to set the screen up. Will start a new thread in the Construction Co page once im open for business..

Oh and the shaker pan seems to work well with a 970 rpm gear motor attached. I tried 3 different speeds and of course faster was better.

I had started to run the D10 around (first time in the dirt) and grading the ramp that goes up to the top and was happy with its performance, and was gonna take some vid when this happened..




Have the parts to fix it now,so will hopefully get it back outside soon.

Thanks for looking.

I can see the pics, not sure what the problem is.

I see them now except the first one. Great build looks good. Look forward to seeing some videos of it.

Here's a screencap, of what I see, taken just minutes ago.

If i hit view image, it sends me to a google login page. Is there a way you can set images to public?

[JDH429]

Ok, giving Imgur a try. Seems like google photo was generating ridiculously long html and maybe screwing things up. Hope this fixed the problem.

Much gooder, I see the pics now. Looks good, a nice build.

looks great now. what belt are you using to spin it? Also on the drum is it ribbed for the bet or just tension grip spins it?

Thanks, I went with a timing belt with teeth and printed a gear to slide over the drum. Got the belt from servocity. Also switched to a 100 rpm gear motor which sounds really fast but looks to be just right. Still trying to finish a few things before I start testing with dirt. The rollers need to be machined out of alum next and going to use a Picoboo prop controller to run the motors. They are pretty neat because you can program sequences and use lots of different triggers to start the operation. I've used them in the past for Halloween props that work off 12v wiper motors. They also play sound files you can load. For even more realism I might try to record some machinery sounds from around our shop and mix them together. For example, record the lathe starting with the chuck on a high rpm, which winds up for a few seconds and use that every time the trommel is triggered to start.. I'll have to play around with it.

Yeah mate, that fixed the problem, the Trommel looks great too by the way.

Very cool! This is on my short list, I need to be able to bust up clods and/or sort dirt! Great work and thanks for posting!
