Mike - thanks for the compliments ......
The dump was made using CA glue. Since then I have discussed it with Travis - should have used styrene weld - I believe the joints would be much better. There are weak joints but none have popped. It has only seen the crushed rubber. I believe it to have enough power for dirt though. If you are familur with the Sand MAster units - it takes three whole hoopers to fill it.

http://i262.photobucket.com/albums/ii94/Isleifr/dump%20trailer/P1164627.jpg

On the low boy - I copied the pictures of a trail king into a cad program then drew over top - so the lines are there's - the details are a bit different though. Here area few more pics of the workings of the neck..... I'll look for a video of it in action - several people have taken vids over hte past two years - many don't share though....wonder why???

i have a flat bed trailer costume built by freddy and i am looking on how to secure 1/16th scale john deer tractors to the trailer with the stock flat bed chains. i have 3 tractors to hold tight to the trailer any help would be great. now the trailer has 5 loops on the side of it allready to pull chain through it but i cant figure out how to pull them tight and keep them tight . also i am 2 loops short so i need to think of another way to tighten them down. any help would be great thanx cory!

Oh I see Izzy, you used a fifth wheel on the bottom of the neck... That works for sure.

The real things have a surprisingly easy attachment method.

The trailer really looks good. Congrats..:)

Izzy
11-01-2010, 07:23 PM
Mike - check out IhBuilders home built - he is working on a really scale attachment method - very realistic..... Also if you had a chance to get a unit out of PMD - they are very realistic as well - especially if you spend the extra bucks for the hydraulic unit.

Tanker Yanker - I would strongly suggest the turn buckle concept - nice and secure - the over center binders from PMD work but are very delicate - but are fabulous for detail.

All the trailers look great guys, very inspiring I wish I had more time to build.

They are delrin tube with a thin brass tube inside and an aluminum axle shaft for the bearings in the wheels to run on. For the rims I driled out some plastic hex hubs and inserted a flanged bearing and drilled out the out side rim to hold another flanged bearing so each set of rims has two bearings an outer and inner. I then threaded the aluminum axle for 3 mm screws to hod the wheels on. I will post some pics in a minuite.

Travis This question is directed your way. First thanks for starting this thread ,as there's going to be lots of question coming your way. First one is, You seen to have used lots of different all thread sizes, does that depend on the load weight or the length of stroke for the slider. What rpm gear drive and torque power seems best. Whats the best lift action, to push from the front to the back, or back to front. That's it for now. Thanks

11-02-2010, 09:32 PM
I use 10/32 in all of my builds but the dump trailer and it is 3/8 fine thread. The dump trailer was my first screw drive and I did not think about the fact that the sliding block would carry the load and the all thread just had to move it. All of my screw drives push from back to front. For gear reduction my traler is 32:1 with a 65 turn 540 lathe motor the two dump trucks are 50:1 carson gearmotors and the dump pup trailer is a black & decker $10 screw driver from Wall-Mart.:cool:

travis , I have to correct you on 1 small thing . the thread does carry the load and the greatest of the load in the down position . your force is transfered from the motor through the thread to the carrier to the push rod to the box . now for our purpose a 10/32 treaded rod is plenty but you start increasing power and weight your gona brake something . most likely the thin threaded rod could start to bend or the body will push out at the rear hinge or in the front where your rod is connected . now like I said for what we do all the screw drive I've seen are sufficient , even over kill

Exactly Steve the block holds the weight and the rod provides the push.

Thanks guys, that helps a lot. I have a large sheet of paper in front of me right now and trying to put this down on paper. I've got the Rod thrust bearing and a piece of nylon for the slider and I'm just figuring out the length of the push rod. Looks like it's about 8". What's the normal tip angle for the box to empty, I've used 45 and hope that's high enough. I think now that I should have waited before I ordered the gear motor. I only ordered a 34 rpm and it's going to be way too slow. Look like it would be better in the 150 rpm range. Anyhow, thanks again for the help as I'm getting more on track.:D

to attach the turnbuckle - go buy some link chain - check out the jewelery stores and the craft stores for some "chain" - use a larger link to attach a hook to each end - as well as each end of your chain.
Also - PMD and others have aluminum hooks that are casted .... They work nicely

this is the lever that closes the latch when the bed comes down to rest on the frame . It takes some tweaking till you get it right , but it works like a charm :)

That catch, you built is great and if you don't mind I'll change it a little bit and try to make one like it. The way it opens when the box lifts is what I'm looking for. :D

Lil Giants. Sure was asleep on that one. Thanks for putting up pictures of your method of locking the gate. I built the lock arms and and then when working on the rest of the linkage remembered that I had a crashed Helli with some very small servos. I pulled one out and it fit right between the box rails, no problem. Needless to say that's how it ended up, servo operated. But thanks guys for posting your ideas.;)

Lil Giants
01-03-2011, 01:10 PM
The auto-mechanical way works pretty good, but sometimes the lock sticks with too much weight against the tailgate... usually when it's out of my reach, like dumping outside with me in the basement.

The servo lock is quick, clean and works every time. ;)

How do you guys make your axles? I've seen a few different ones but not having a drill press (yet) what do you use to make them? Material and tools?

Your quad axel low boy is awesome. Can I ask what springs you used for your simulated air ride?

Izzy, I love that lowboy. I was trying to think of a way to make it couple/uncouple from the bottom of the actual neck to make it as realistic as possible and you've got it. Great looking design!

I have wanted to build a lowboy for awhile, but kept being put off by how to create the "angle" of the frame at the rear, (that the suspension attaches to). I don't have the facilities to mill out an angled frame, and have been looking for some type of suitable angled bracket I can use, (I didn't want to use 90 degree corner brackets). I recently found these 135 degree aluminum brackets that are used for robotics builds, and think they might be just the ticket. Height of the straight part is 1" and thickness is 0.080". When you "invert" two against each other to form a zig-zag angle, you can change the top-to-bottom height from 3" to just about 4-1/2" by changing which holes in the two plates line up with each other. (Sorry, I do not know how to do photos, so I hope I'm not just confusing people). Cost is two brackets for $3.99, and I ordered four sets in case I have to double them up for strength. Their website with a photo is here: https://www.competitionrobotparts.com/shop/brackets/1in-wide-135-degree-plate-bracket-2-pack/
I hope that these will allow me (and others) to build a trailer that they weren't able to before. -Mike
