990 cat loader

[doodlebug]

on a side note : those who where @ cabin fever saw this roll down the side of the pile after Scott distracted me while working on top the high wall :rolleyes:. Any how notice the FWD slant in the ROPs . I thought it look a little bit more then what it originally had :rolleyes: So took a closer look , sure enough it bent on the roll over :eek:

Hmm? Time for 3 finger Joe to sing his song! http://www.youtube.com/watch?v=v26fTGBEi9E "Shake Hand's With Danger" :cop::cop::cop::cop:
Yah I like this one, except the loader scene!
Cheer's, Neil.

steve you should have gone to maaco they would have done it for 59.95

Steve, it's an amazing job you did! I'm looking to buy a such construction machine for a while, but you greatly inspired me, and now i'm seriously thinking about building a such machine like yours. I read through the whole thread but didn't find anything about wheels of that size. May i ask, where can we get them?

[ihbuilder]

Hi , Abel ,thank you :) The tires are from the tamiya mammoth dump truck which is no longer in production . Do to that they're getting hard to find . I have a mold drawn up ready to machine to make my own (when i get to it :() 90% of the machine is self made including the wheels .

[AbelVincze]

Thanks for the quick reply! I'm also investigating how a self molded tire can be made. I can't wait to see your's finished:)

[AbelVincze]

Steve, can you share some info about the gear motors?
First: as i read in most of the gear motor specifications, if the output shaft is blocked, it can damage the gears. Let's assume, that the shaft is never blocked cause it have enough power to drive the big wheel, but what happens if you turn (left or right) while the machine is not moving, are the wheels turning as expected, or are they still and sliding on the floor? (hope you can understand what i mean).
Secondly can the wheels turned by hand (slowly ofcourse), or could this also damage the gears?
(the 2 questions are the same, i know:))

I know this mostly depends on the gear ratio you're using, as i calculated, to get the max speed (1:1 -> 22 km/h, 1:14,5 -> 1,5 km/h), a max output of 50 rpm is needed. So i think, the best is a lower rmp motor as base to get the lowest gear ratio possible...

[ihbuilder]

Abel , I didn't go with the 4 gear motor set up in the end . Even they where to flimsy for the size and weight Of the machine . I went with a differential set up which seems to be holding up quite well :) I don't have any experience on using a gear motor at each wheel yet :o

[AbelVincze]

Steve, ok thanks, i thought you've tried it... For some reason i don't trust these gear motors either...

Also this is the 2nd thread of mine you post this in , what do you mean :confused:

[AbelVincze]

Hi again.

In the last 2 month, i collected a huge number of Cat blueprints, with aid of these documents, i built a 3D model in 1:14,5 with every little details - Some of the inside mechanics are still missing, but they will be done shortly.

Steve, before going further i will make a new thread for it, but if you don't mind, i share the results here: https://www.behance.net/wip/316985/659439

Friend'm from Brazil so I write in Portuguese! and I meant in the first post congratulations and perfect in the second post I meant cool!

[Fired up]

Nice loader looks like a mean digger. I like the weight.

[ihbuilder]

[Supermario]

Always great to see the 990 progress. The pins and locks look spot on Steve.
I think the broken keeper is perfect! I look at a pin like that it tells me, that one went dry seized in the bearing and the pin tore the lock off and was repositioned after repair.:p:D...another touch of realism;)

[JAMMER]

Great job Steve looks real good. Ed

[Cooper]

That's great way to make those pins!!! I've been thinking on how to do such. Sometime in future I'm going to use your idea and get rid of the c-clips I'm using on pins. I tried to make the flats undersized and press pins into but just not enough material to make tight enough and reliable. And loader looks great!!!

[TRUCKMAKER]

The pins came out nice and the loaders looking better all the time, but what I really like is the jig you made to mill the pins! Nice job! Sometimes the set ups harder than actually making the part.

[modelman]

[QUOTE=ihbuilder;108228]man what a ##### :eek: the lil keepers
Just wait a few years when you can't see and your hands are shaky and then try the little parts. :D Hopefully it won't happen to you but enjoy things while you can. Nice touch on the detailing of the small parts. These things make a model.

[JAKEBRAKE]

Steve,

Nice detail!!! I agree, normally it takes longer to setup a part than run it.

[Espeefan]

Great work on those pins, Steve! 16" of reach makes this Cat a monster!

[od jhon deer]

nice build but noticed u steal haven't done the up grade to the tires barn hausen modellbau might be a good answer he has a large selection

I have some on order since Christmas from RCM which I think barnhausen makes them for RCM, not a werd yet :( . I tried Barnhausen directly with no reply . I was hoping to have them for this week end :( There was only 1 size I saw that was close .

[Lil Giants]

So what's the bore size of your new lift cyls?

holy jeepers looks like I'll get new tires after all :jaw::jaw::eek::eek::cool:

they're solid too :D:bounce:

[Espeefan]

All I see is an awesome drop deck trailer..... :D

[AbelVincze]

Nice:) Can't wait to see it installed.

I checked the site from where you ordered the tires, but unfortunately i didn't find the right size (D 173mm, 75mm, inner D68mm). I will ask them if they are making custom size tires.

[JAMMER]

HI Steve well it looks like they will work and be better than what you had on it. Ed

[RCP57]

Nice kicks Steve! Why so many????

Awesome dude! I love watching the video of it and the Mack 75! How is progress?

[ihbuilder]

I've been taking the weekends for myself lately (well trying :rolleyes:, got the next job started this afternoon :rolleyes: ) . So, I finally got to make new wheels for the new tires :eek: In steel no less :D . each wheel and tire assmbly weighs in at 4lbs 2oz , so I'm adding almost 16lbs when you figure the difference . It'll 60+ lbs now . Process pics from start to finish .

Nice work steve!! What holds the tire bead to the rims?

[ihbuilder]

Nice work steve!! What holds the tire bead to the rims?

Thanks Tom , the tires slip over the bead (barely ) to a nice snug fit . Its almost impossible to pull them off .

I put 1 on the back this morning and no more squishy tires :D I'll post pics later in the week all painted and mounted .

[modelman]

Okay steve. I get it. Watching your video from "cabin fever" it looked like you were operating with a flat tire. :eek: :D

now that they're done next valve rebuild , windows ,lights , sound (maybe) , decals , railing/ladders/steps and more paint wear :D.

[Lil Giants]

WOW what a difference a thicker sidewall will make, the stance looks much better!

Do you have two extra of those tires & will they fit the Mammoth rim?

[ihbuilder]

thanks Joe , I wanna get them dirty :D

No extras . I got them off RC machines . They are made by Barnausen.de ,I think, I tried contacting them with no luck , so I went through RC Machines . I waited a bit for them :( but worth the wait :) . They're just a tad narrower then the mammoth tires but will fit if you cut the webbing off the wheels .

[modelman]

Tires look great steve! I looked thru your thread trying to find out why the front fenders are not painted and all I found was "the painter didn't do it". Will you do this later? This model will look great with all the things you have planned next.

[speedy8305]

hey IH that looks great i used to work for a company who owned one and lol it looks like you stole it and shrunk it down but great job on the build keep up the great work

[j_hammer]

do you have a link to where you got the tires from.
