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.

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.

[JDH429]

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

[Efroeh]

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

Ok cool. Pics might need resizing.. I was in a hurry when i posted.

I can't see the photo as well.

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.

[skeeter]

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!

:eek: :eek: Trommel looks great 👍 Looking forward to see it in action!

[JDH429]

Thanks, might get a chance to test this weekend. Will def post a vid of the good or bad.

[JDH429]

Spring blocks and new rollers are machined. The initial spring setup was crude but was helpful in getting an idea what the movement was going to be like. Determined a stronger rate spring was needed to handle more weight in the hopper. Also added a heavy counter weight to the shaker motor to increase agitation due to the stiffer springs. Wired up and painted...Works well, Test video attached.

That thing is COOL,:cool: and great background for the photo!

[Northern Farmer]

Wow you knocked it out of the park! Nice piece to be proud of :)

[Bo Wallen]

Now that's a cool build ! Would like to have that setup in my play-park.......:D

[frizzen]

Wow. That came out beautiful.

Are the footers on that height adjustable, or do you need to level the site first?

[JDH429]

Jim

Thanks Jim, didn't really plan that I was just setting it down on my way to the barn and grabbed the spray can from the garage before I painted and decided to snap a before shot.. before grabbing it again. Worked out well I guess.

Wow you knocked it out of the park! Nice piece to be proud of :)

Thank you! Looking forward to dusting off the Vario and getting some dirt dumped in this thing.

Now that's a cool build ! Would like to have that setup in my play-park.......:D

Thanks Bo, I guess I can always lease it out :)

Thank you, that's a good observation. I didn't make them adjustable at all as I figured the whole structure needed to be mounted to a platform which it is ( plywood base) and the concrete blocks add enough weight to the whole thing to keep it still. It tends to vibrate quite a bit from the shaker motor. So I'll have to level the site where it will be set up.

[Efroeh]

That unit is sweet. You could start selling them is be in a line up for one.

[Rvjimd]

Jason,

I just watched the video again and went thru the build thread, very cool!

Did you start with a scale/plan in mind when you drew it up? Do you plan to park dump trucks under it, or separate the piles with concrete barriers and then load out with a wheel loader or possible use roll off dumps?

How tall is it overall and if you are scale I assume you are trying to match the bruder and tamiya stuff?

I'm just trying to figure out a few of those things before I try to hack something together. :rolleyes:

Did you consider a jaw crusher for part of this setup? I wonder how hard it would be to build something in that scale and have it perform well?

Thanks!

[JDH429]

Jim, The first thing i wanted to do was make sure that i could dump into the hopper without any issue so measured the width of buckets on my machines. Then yes like you mentioned, i wanted to be able to park trucks under the drum or just use the front loader to move material out. Thats why its so tall at 23" to the top of the bin and 30" wide on the outer legs. I plan to build conveyors to stick under the drum as well for stock piling...Havent got that far yet though. One thing i wish i wouldve done was make the shaker bin angled so a screen could be layed on top to catch any really large clumps. I may address that in the future if i find its a real problem. The passage from the bin to the shaker pan is smaller so that would keep anything too large from going into the drum anyway..

A crusher would be cool, Prob not too difficult. I did look at a few online before starting this but wanted to sort by size because i was interested in building a road using asphalt grindings i have..Thats what got me started down this path..

I try to scale everything to 1/15 to work with the Bruder and Tamiya stuff. Heres a few poser shots with Bruder and Ertl 1/16 stuff.

Jason,

Very good, the new photos help me visualize the scale, thanks!

Very nice job. The weathered look paint gives it an added touch.
The sound recording around your shop sounds like an interesting idea.

[Azonic]

Nice job on the trommel!

Off topic, are you going to just paint the mdf walls in your shop?
Have done the same in my new shop so just curious, I'm about to paint my mdf boards this weekend.

Thanks! Will do.

Thank you. I tried capturing the feel of an older plant maybe built in the 50s, similar to one at a gravel pit we used to haul out of when I used to drive.
I posted a vid link above with the sound. Ended up taking sound clips from YouTube videos of electric motors, locomotive and a rock crusher and mixed them together.

Kalle, thanks. I had thought about painting the walls last year when I built that room but never got to that point yet. Lightening up the walls would be nice to brighten up the place. What color you thinking? Spray or roll? White would show the least amount of texture on the mdf.

Ok I see.

I'm going to paint them in a white color, I will use a roller to paint.
It will lighten up the room quite a lot I think. I can send you some pics when I'm done, I'll send you a pm.

Sounds good Kalle, Hope your paint job goes quick and easy.

Field test went well, but started to rain before i could record any video. Getting the remnants of Harvey through our area today..So here is a few shots of the site. Side note- This is the first time for the Vario in the dirt.:D

Thanks Bo, I need that contact info from you cause now I need to ask Santa for some trucks to haul all this finely sorted material around. ;)

[Northern Farmer]

Have you considered offering the trommel as a kit or rtr ? Not many folks have a trommel that looks and functions this well. Could be an item of high interest.

[Finster]

Wow nice job. Now I want one too...

No Problem.....here you go. http://www.santaclausvillage.info/santa-claus/santa-claus-main-post-office/ Make sure Wife/Girlfriend get a nice handbag/shoes.....then you go all out........:D

Thanks guys. I have considered it like some of the other projects. May need to upgrade a few things to try to make this a quicker process. No clue what a reasonable price would be.. pretty big item..

Haha, He actually has his own post office! Am I a moron for not knowing he is Finnish? That's good advise there, will also be able to run trucks with a clean conscience.
