Re: CAT 535C Grapple Skidder
 

Nice soldering job. Are you using a resistance unit of just a small torch?

Re: CAT 535C Grapple Skidder
 

Thor- they are 20rpm gear motors.

9W-Monighan- I am using a "regular size" torch (same one I use if I am doing plumbing) for the work. I'd love to get a resistance soldering unit though...just don't want to spend the money.

Thanks to you both on the soldering, only other brass I have done is what is on this model. Does require two rare commodities though...time and patients! I don't have much of each in my opinion.

Ben , your doing a fine job ,these models take a lot of time . I learned to go to another if I get frustrated on 1 thats why I have so many going :p .

Snochaser-very nice build you have going! Don't know what scale you are building but the model looks kinda big. Could you use a modified (full rotation)micro servo as a rotator and build a round case around it to hide it. Don't know how much torque you need but just a thought.

Re: CAT 535C Grapple Skidder
 

Modelman- It's 1:14 scale, if I did it correctly. I still will have a problem with lines twisting if it rotates. That's the booger. The other motor I have would be good but.....

Re: CAT 535C Grapple Skidder
 

What about mounting it rigid and just let the servo arm rotate? Have the grapple mounted to the servo arm.

o my skidder is a long lost projet mabey this winter if i get time hoping for a lon clod winter and like 8 mounths with all the stuff i need to get done lol. there are some videos on my youtube

Ben-

GREAT work! You're doing an awesome job. Keep the updates coming.

Re: CAT 535C Grapple Skidder
 

Nice work, Ben. I wish I could solder like that.

Re: CAT 535C Grapple Skidder
 

Thanks guys!

Modelman- I believe I know what you are saying, not sure I could fit the servo though. I may look into it.

Mog- That thing looks like a beast, quick and torquey.

Re: CAT 535C Grapple Skidder
 

Yeah after thinking about it,a servo is probably too big.

Very nice work!! Maybe you will be hauling logs soon.

Re: CAT 535C Grapple Skidder
 

nice job i can't wait to see this thing in action logs pipe what ever you can think of draggin behind it :)

Re: CAT 535C Grapple Skidder
 

Very nice!

Re: CAT 535C Grapple Skidder
 

I'm hoping to get a lot of work pickin' up sticks in peoples yards. LOL

I'll have to move it in with my new Pete that should be here in a week or two from SemiJoe. Oh....guess I'll have to build a trailer first.

I am gettin' antsy. I want to try it out. I think I will be waiting for quite some time more (and quite understandably so) for the hydraulic pump though.

Thanks for the compliments.

Re: CAT 535C Grapple Skidder
 

Really nice work Ben. Insted of it being able to spin 360, you could put stops on it so it would swivel to a limited range. Just a thought.

Re: CAT 535C Grapple Skidder
 

Great job on the grapple and the skidder itself. Have you checked with any machine shops to see if they could make a mini rotator for it? No clue what they might charge for that, but it's an option if you really want it to be able to spin full 360.

Another option might be to use those linear actuators for the grapple cylinders and an electrical slip ring instead of hydraulic.

Re: CAT 535C Grapple Skidder
 

looking good, the grapple looks strong. nice work,

Re: CAT 535C Grapple Skidder
 

I have thought of something like that, but not sure how to do it. I don't know if I could run it through the speed control and then limit it through my remote.
