D8R +463 in 1/5,6

Hi, starting here with some pics on my models as far as I´m today.
Build mostly during winter season, have other old trucks and machinery to take care of during summer.
As seen on second pic, I try to make some parts in heavy paper to get dimension right before doing it in metal. This is the lower oil tank (the original fuel tank will also be used for hydraulic oil). Do need as much oil as possible since machine is hydrostatic driven.

Very nice D 8R and pan. It is all run on hydraulics? That is quiet an idea and it looks good so far. Ed:eek:

HOLY COW!!! that's freaking awesome in size!!!

I'd luv to hear that dozer scream with power while under full load... anything on youtube yet?

Have you weighed the dozer or scraper yet?

Glad you found us Dan, you will like this site and like I said before these guys will love your work.

Did you ever find any valves that work for you? Have you made any more progress?

awsomely big!!!! thats cool will it be r/c or rideable?? lol very nice work

Re: D8R +463 in 1/5,6
 
Thanks guys, the weight now is 410lbs on D8 (that´s dry, just oil will add another 30lbs. The 463 is about 230lbs and designed for a load of +220lbs.

The D8 will have (if I have calculated right) a pull of 620lbs so if should be possible to do the same work as the big one.
Still has some 100hours beforeit can be started, needs inside oiltank, connections, servo installation, muffler...........

My location is just south of Stockholm, Sweden. i´m lucky because a friend has a set up of D8R (series2) with a hydraulic converted 463.
I have been at machine show in Brownsville 2 times, seen your fantastic work, unfortunatly have not got the possibility to meet you, if I make it a 3 rd time I will sit by the model until we meet.

The hydraulic system and it´s components are set now, got some fine small quick disconectors from Rectus, they have a dia of 10mm (3/8") and they are closing both ways.

The model will be radio control, now looking at Futaba 7 channel or a Robbe 16 channel.
From earlier discussion with you Joe, since I have 2valves that supplies the 2 hydraulic motors, I need 2 servos that should work together to recreate the function on the real one. R/C controlled airplanes uses sometime a similar mix on steering and height control. The valve used is from HAWE and is compensated so needs very little force to move valve (in fact I will go on midi servos).

Have tried to upload pic with 640x480 size, (says it should be 280 in height, don´t know that format) but it only comes as thumbnails, any hint how to get them as big as other pictures on other threads??

Will post progress, but right now only playing with the 1:1 equipment ,see thread "americans in sweden".

Have a nice weekend (wishes I was together with my other swedish friends visiting the HCEA convention this weekend).

Dan, Too bad you came all the way to the USA and didn't find me. The 08' show had the model there and my wife was working next to it and she told me alot of people asked about it but I was busy working my 1:1 Cats.
By any chance are you Gilbert's friend? or alias Quad?
20yrs ago I started to build a D6H but big enough for my kid to ride on but never finished it because I didn't have enough money to buy the diesel engine I wanted for it.
I think for a radio,get a Specktrum DX7. I've been told that these function flawlessly. In fact I just bought one on ebay today. When I was using my 72Mhz radio at the show last month,I had alot of interference due to the steel super structure and on occasion somebody's cell phone while standing next to me.

D8R-very impressive work! On the pictures, if you are using a host site be sure the pics are 640x480 then just paste the img code directly onto your message and the pictures should be there.

That is a very nice build you have going on there. What size motor is that you are using? Please more pic!!

Thanks for the comments,
Steve, googled on the DX7, do you or any else know how the reciver will work when placed inside a metal box. Did plan to have battery and recivers inside the left box on machine. Don´t want to place it inside cab, this should look just like the real one. Another way is to build the box in styrene, but will it work with the antennas still inside the box?
Company selling Spektrum here localy says it has to be a "SPM2712E" code on box to legal? Buying here in sweden it cost $400 without servos, that a little higher than ebay but with ebay I have to pay freight, sales tax to get in to sweden.

Trying a bigger pic on the engine installation (Honda GX100, 2,5hp)

well it doesn´t work with my pic, had no problem with posting them (same size as here) on HEF and the program for both forums look the same. I have all my pics on my computer, not on any other source and I don´t like thumbnails, you should see the pic in right size direct! Hope someone can give answer to this or should question be adressed to moderator?

I will gladely post more pics on the models if I don´t have problem posting them, any special detail or wiew wanted, just put in a message.

Re: D8R +463 in 1/5,6
 
If you go with the 2.4 Ghz you won't have any problem being surrounded by metal. I isolated my antennas with a piece of rubber and made sure the bare tips can't touch anything and it has worked fine. Just make sure you follow the instruction that comes with the rx and it will be fine.

I load my pics into Photobucket and then copy and paste them here, it's a lot easyier. That attachment garbage didn't work for me on HEF.

Re: D8R +463 in 1/5,6
 
SmallHaul Scott would have the answer for the radio receiver. He did tell me one time that the receiver could be hidden deep inside of my dragline frame. Not sure how legal anything is. All I know we're not using the radio at some aircraft meet.:D

D8R 09-13-2010 03:43 PM

Re: D8R +463 in 1/5,6
 
Thanks for quick responce, guess I can´t use where to place reciever for an excuse to not continue the build, ha ha.
I will try the Photobucket way tomorrow, still amazed that posting pic in forum should be so hard, the forums is all about sharing expirence (text and pics)!

Very nice pics, way cool model

For the forum to provide photo hosting adds to the monthly cost of bandwidth useage & storage on the host server, there's only so much bandwidth/storage allowable at a certain $rate... the forums are free to use... If you click pic twice, then the original size can be seen.

Set up a free photobucket account, it's better for everyone involved. ;)

Did you ever see "dozernerd" on youtube? He had like a gas engine D11 in about 1/6th scale... I tried to get him to join the forums a few yrs ago, but he wasn't interested. I see he has since deleted his YT account. He was from the Pacific northwest USA.

Re: D8R +463 in 1/5,6
 
Now I have got a photobucket account running so guess I can share more photos.
During last week I discovered a problem with the ripper attachment. When making the drawing for ripper, I took mesurments from a D8N but the upper part like fuel- oiltank and cab is from a D8R. Main difference between those models is that R-model has larger fuel tank and a new design on ripper attachment.
With my mix, upper cylinders hits the tank when ripper is up.

http://i1014.photobucket.com/albums/...n/DSC_0070.jpg

So lessen learn: never mix between different 1:1 machines.
I will make new drawing on brackets with new position for upper cylinders. At same time lower part will be redesiged to the clever solution of coupling my friend has. This will make it possible to have most of the drawbar mounted. In real live it´s foldable when not in use.

http://i1014.photobucket.com/albums/...n/DSC_0048.jpg

Yes, I have had some contact with "dozernerd" and the videos was nice, don´t know why they have been removed. Sorry because he has a good looking model that´s working well. He did use a 6hp petrol engine with generator and electric drive (maybee Cat got the idee to D7E from this model?)

Re: D8R +463 in 1/5,6
 
Did build a carrier today to transport the D8 out of the house (no, will not be able to run it out, have wooden floor that gets bad). My workshop is located in ground floor but have a 2 step outside so needs a ramp to!
It is designed to take everything except front blade and arms.

Looks great! Just for size reference, how big are the "tiles" on your floor??

D8R 09-26-2010 01:53 PM

Re: D8R +463 in 1/5,6
 
Thanks, they are 15x15" and machine weight is about 320lbs as hanging.

Looking good! Is it ready to go? If so could you show us a video?

Re: D8R +463 in 1/5,6
 
WOW!!! Now that is a dozer!! Need to make a video of it running around so all can hear it running.

dirtpusher9 09-26-2010 05:17 PM

Re: D8R +463 in 1/5,6
 
That is a cool device for moving it around, Dan.

Re: D8R +463 in 1/5,6
 
Your rails for your tracks are cool did you machine those out or did you buy a small set for something else?

JAMMER 09-27-2010 08:54 AM

Re: D8R +463 in 1/5,6
 
This is another great build can't wait to see this push some dirt it certainly isn't lacking for weight. Well let me see if I sell the excavator and the dozer and the loader I could get me a little OC3 Oliver to play with in the back yard I wonder if thew manager of the complex will mind. Ed:eek:

Re: D8R +463 in 1/5,6
 
Thanks guys for the responce!
No it´s not ready yet, have a lot of work to do before it can be started but will post a video as soon it´s running.
The tracks was designed in CAD to try to find a simple solution that looks like the real ones. The problem is that all commercial available chains has drive pin centered but a CAT chain has it a little offset. Well it´s a small detail but I decided that it was important for me at that time, today I have had gone a easier way.
Guess that finding suitable chain/tracks are as hard as finding tyres that can be used. To my 463 I found wheels with almost right dimension but of course with wrong pattern (I can live with that).
The parts are laser cut in 3-4-5mm steel, all parts mounted in a holder to be spotwelded and then the assembly goes inte a own to be brazed together (thats the color you can see between parts).
Each assembly is connected with a roller and 2 insex screws (next part is swiveling aroud the screw head. There will be some wearing on the parts but I think it will last for me (or I have to make new parts).
They still misses the 4 screws that should hold the plate, will be added later, but they have no function, only for the look.

Re: D8R +463 in 1/5,6
 
Very nice. I like the way you mortised the vertical piece onto the grouser plates. That definitely saved you hours of machine time. I guess you TIG welded them on and put a small tack on the ends and ground it down. What kind of steel is that? It looks like stainless:confused:

dozer 09-27-2010 04:32 PM

Re: D8R +463 in 1/5,6
 
Heres an idea for your tracks. They dont look scale but they would work. Use attachment chain then rivet the treads to it.

JAMMER 09-27-2010 04:41 PM

Re: D8R +463 in 1/5,6
 
Those cats and rollers look great your doing a wonderful job keep it up when you get that old girl done you ought to be able to push some dirt for sure. Ed :cool:
