How to turn a bowl shaped part?
Well, do not have any radie-turning tool for lathe, so had to do as good as possible with normal bits and then making the last steps with a file. Doesn't feels good working with file when lathe is running.
Have seen some solutions on net, anyone having suggestion, all input appriciated, need that if making some wheels for next model.

Aircleaner top bowl


Anti skid plate mounted outside cab,


and got some nice cable for GPS, here just testing how it looks. Cables are those that stores selling phones use for safety (prevent stealing the phone). There's different sizes of cables, this one was the smallest one and has right diameter of the spool. Connection in both ends will be remade.
When building models, you should always keep eyes open, useable parts are everywhere!

Nice job on the pre cleaner Dan. If you had a lot of those to make you could make a wooden pattern and spin thin aluminum over it.

[td9clyde]

nice work I can't wait to see this move and hear it run

[D8R]

Thanks guys, me to waiting to hear it.
But found out that aircleaner was missing something, here the real one


and model


A little hard to see, mesh should should be finer, but this done for durability. Have learned from shows so far that visitors can't read (signs say DO NOT TOUCH) leaning, peeling, and looking with the their fingers
Here a close up pic, don't know the reason for why some holes missing but that's the way its looks.

Nice detailing again, Dan! Really incredible. Don´t want to push you*, but I see the original air cleaner has some kind of flange at the bottom

Stefan

*) (yes, I do)

[doodlebug]

Ever thought about putting up an electric fence around it?
Lol! Shock the ???? Out of them!
Like the progress!
Cheers, Neil.

Happy now Stefan? I could see that coming


No laser shop open this morning so did it old fasion style with drilling, file and so on

Well Neil, sometimes you wounder about how people think (or maybee do not), have had parents being angry when I tell the kids to not touching/mowing things like the doors. Just waiting for that day when they steal the driver or his dog inside cab. BUT most visitors are realy nice, interested in the build and eager to see all details and how things was designed

Ha, very quick reaction, Dan . I´d say that´s 1:0 for you.

Looking better all the time Dan. But you are killing me having to wait and see this master piece run.

Thanks, yes I know it's taking so long time but who's waiting......
Will try starting/breaking in the Honda engine next weekend , I hope.
But the goal is to have it up and running this summer

[D8R]

Did not get it started will not say anything now until I have done the start.
This weeks evenings (have max 2 hours of time/day) redid the connections between machine and pusharms.
(old photo some years ago when planning how cab should be done)


Was never happy with the simple solution, did mill new ones from a bar. Amazing how much time it took, did use an old steelplate (have not yet made that cheeseplate Reg used) to mill some parts at rotary table.


Didn't separate the 2 parts until almost finished, have a swivel bearing inside


Had to modify the bolts to fit inside swivel and getting as much movent as possible


The new connectors welded to pusharms, looks now like proto

Hi Dan

OMG what a Big Build you have worked on for over the Past ten years.

Love you work, can't wait to see I Video of it running.

From Cameron.

Hey Dan, read thru Jeff's forum, http://www.hydraulicinnovations.com/...read.php?t=449 and get some idea's for your future transport truck & trailer. I can give you idea's for hydrostatic drive. pm me with questions.
More progress on the "Kitty"
Cheer's, Neil.

Neil, thanks for the link! Have not decided what type pf power there will be in the truck, would like to have a small gas engine , like Honda GX25 or GX33 with a real gear box. Have looked at Eatons hydro parts, we'll see.
Havn't figured out how to move dozer without starting engine. Today I have to remove gears in hub reduction but that will not be practical to do every time machine is moved. Don't know how much force needed to get hydraulic motors turning.

This weekends update:
Steps om push arms was missing, did weld a 6mm steel rod on and increased height with some welds, grinding down to get the anti slip pattern.


The rear part of engine comparment was finaly done
Connection to ripper is with quick couplings (will use same outlet for scraper), was not satisfied with the small blocks, did make new longer with a recess to take strain from bolt when cylinder moves. Of course, first one was made with connection wrong


Planning for some painting next weekend on new or remade parts. Still windows to cut, make the connections at cylinders, but no more new parts on "to do" list. Goal is to have model running 3 rd weekend of june at a show north of Stockholm. If everything goes as planned it can be done but still not convinced that all hydraulic will work flawless from beginning.

Dan awsome work...Cant wait to hear this cat run and see it in action..You must get alot of compliments on it at the shows ..dont know if you have seen there are a few larger rc dozers workig on youtube
https://www.youtube.com/watch?v=dCKJQ5S1hcw
Hey Dan seeing you are doing the windows soon thought this may intrest you ..I am going to order some for future projects http://www.greathobbies.com/productinfo/?prod_id=FOR133

Hey Dan, do you have room to tee in a couple of high pressure ball valves
On the drive motor's? That would give freewheel to the beast!
Cheer's, Neil.

[apfubar]

Dan,

Have you tried just opening the valves up that are there now? You could do some smarts with the servos... Its gotta be easy to run the receiver and servos without the motor?

Cheers,

Thanks guys for the suggestions. Have not filled up system yet, don't want to stress hyd motors before they have oil. Today it's almost impossible to move the machine if not gears are removed.
Neil, there's not room for anything more inside, it's cramped!
Will test these when filled up, until then go without gears.

Yes Lou, have tried to follow what's shown on tube. I know of one BIG norwegian D11 (1:4 750kg=1600lbs) that has not been seen there yet, guess that will come when snow/winter is over.
FOUND IT:

Looking really good Dan. As far as moving it, not much different than todays skid steers and track loaders. If engine dies, it sits where it is till fixed, no moving it without something to pick it up. Don't ask how I know (new perkins engines aren't cheap lol ) Old ones had a manual bypass valve you could turn out to beable to tow them, new ones with hydraulic released parking brakes can't do it.

Does the guy with the 1:4 D11 have a build thread anywhere?

[modelman]

D8R-the dozer is looking great! If you want to see how a good operator works, check out D9Joes videos. He is by far the best operator I have seen. Looks just like a real machine working. He is the class of the field in my opinion.
