New Project!

Nice work Stuart!

[Espeefan]

This a really cool build. I've seen the Blocher kits, and I always thought they were nice. I am sure those kits inspired you, and there is nothing wrong with that! I like the simple, clean, and functional chassis design. Those gearmotors have a definite advantage over the ones used in the Blocher kits. I like how the output shaft is centered in the planetary head. Where did you find motors like these? Are they as powerful, or more powerful then the ones that the Blocher kits run?

Thankyou for the kind words, its very much based on the Blocher kit although not an exact copy

I'm yet to find out if the motors are strong enough
I posted where to get them earlier in the thread, they were quoted as 2.6kg/cm
I don't know what torque the Blocher ones have, I think they are made by Modelcraft.

Not much of an update, I made a new bottom plate for the rear, I wasn't happy with the original, also got the lift servo mounted, will swap this for a high torque one later, some goodies arrived so I fitted the lower bearing for the swivel:







Will start on the rear motor tubes whilst waiting for more stuff to arrive.

Thanks for looking
Stu

Got some more done:















Still have the rear hitch and the pivot to sort out
Cheers

Looking good, have you powered it up for a test yet?

[Acadieman]

Looks awesome!

[jack van]

my guess is something realy nice and that i will realy want

Thanks for the comments

I've bench tested the motors, once its a roller I will shoot a vid

Very nice work Stu. I'm looking forward to the videos. This such a cool a project. Thanks for sharing the info and answering my questions.

No worries, its why I joined the forum, to learn and to share

Ally arrived for the pivot:



A couple of hours later:









Soon be ready for the first test vid

Looks nice Stu. Quick question though. The articulation joint looks rigid. Will you make a pivot point for one of the axles, so it can oscillate?

Looks like the whole arse end articulates to me...but what do I know anyway!lol

Nice machine work!

[Espeefan]

Oh crap. You're right! I was studying the articulation joint so much that failed to see the pivot behind it. D'oh! Actually looks like there is a bearing in there.

Ha Ha! Like this you mean:





Both the steering and rear end pivot on bearings.
Thanks for the comments.

Time for the first test vids.
The banging noise in the back ground is the wind, its between 30 and 80 kph today!

Enjoy

Bench test

Articulation test

Looks and runs great! Have you tried pulling anything yet? I'm curious how the motors perform under loads.

[RCP57]

Awesome! I steer my Skidder in a similar fashion and I am wondering if you are going to put limit switches on there somehow? I don't have anything on mine but I guess it would be nice if someone else that wasn't familiar with it was operating it.

Not yet, that will be the next big test!

I've fitted a 10K pot to the steering pivot, not the best pic but you get the idea:



It's connected to a special speed control which makes it work like a big servo, it doesn't self centre completely, wondering if I need to change the pot for different resistance it does however provide limits to the travel just like a servo, so no problem with stalling out the motor against the stops

Made a little progess on the rear end:





Front hitch servo:



Battery fits under the bonnet (hood!):



Couldn't resist a quick body mock up:

Looking really good, Stu. I can't wait to see what you come up with for the 3 point hitch. I might find myself in the same situation someday. I really want to build a tractor.
