4 Hour Bruder Dozer

[JohnStilwell]

that there looks kinda like a grader blade...

Now that I see your fingers for size comparison, maybe you're going for the old school D8 straight blade look.

[RCP57]

Not to worry. the blades aren't finished yet! They will not be a carry blade like on my dozer but they won't be a straight blade either.

Kinda like this. http://www.google.ca/url?sa=i&rct=j&...16951949301575

A little more progress on the blades today. I'm aiming for the look of a D6 with these so no more carry blades. This style will cut a lot better too with such a light machine.

Unbelievable skills! Would love to have the talent you do

[RCP57]

Thanks a lot Barker. All I can say is practice, practice, practice! That's what I do but nothing ever turns out perfect.

I made up these little motor mounts this morning.

[RCP57]

I finally finished up the sprockets for dozer #2 today! They took a long time to make but I think they turned out pretty well.

Killer

I'm always amazed to watch your builds, umm ehh...Craftsmanship !!

Those turned out great! Your really going all out on this one Reg and the results are awesome. These dozers are gonna kick a**.

[RCP57]

Thanks guys. I think they are a little too time consuming for "mass production" but I guess it all depends on what someone wants. I like them a lot and wish they were on my dozer! I got a good start on all the other idlers yesterday so hopefully this one is rolling in the very near future. It will be interesting to see how it works with gear motors vs servos. Hopefully it is more durable!

RCP57-please understand, I am not criticizing your work. You are doing outstanding work on these plastic models but I noticed on your 1st. dozer the sprocket looked a little small for a scale-appearing look. This last one you made looks larger and more detailed and probably fits the scale better (just my opinion). However, I realize that you are trying to build something affordable for these tighter budgets and saving labor is crucial. Maybe you should offer-2- models. A bare bones cheaper machine and an optional model with all the good parts. Just a suggestion but you probably know what you want out of this. I know from my tries that machining detailed parts takes a lot of time and that is money. I am not a big fan of plastic models but I will be keeping up with this!! Very interesting thread.

Awesome build Reg !!!!!!! I know somebody is going to be really happy with that D-6 !!!! wink wink lol !!!!! Another home run !!!!!

Yes the sprockets on the first one were just to see if the conversion would even work. I made them up out of two pieces using chunks of stuff lying around my scrap bin. The new pair are one piece and made to look much like a D6 planetary. Even though the sprockets are exactly the same as the original ones I made the planetary hub larger to hide the sprocket and look more "scale". You're right, cost vs build time is almost always an issue so I'd like to keep it simple...Well actually, I would like to build it very detailed but trying to get $1500-2000CAD for a conversion like this might be tough. If people are willing to pay then I am happy to make the parts however they want! I won't make anything like the first drive parts again. I was just thinking that instead of drilling all those holes and making fake bolts, I would just drill dimples and save a bunch of time. When it's finished though, all the critical parts are metal so I guess that price maybe not so out of line. I don't know

I'm glad you like it Keith! I hear Santa has it on someones wish list for Xmas this year so this elf is working hard....

Hey Reg, set the sprockets up on a rotary table, make a plunge cut with a hollow end mill, the nub left can be the faux bolt. see link, http://ecx.images-amazon.com/images/...JL._SX342_.jpg Then index to the next bolt position, new plunge cut with depth stop. Clean the rest up on the lathe later. Hope this makes sense?

Cheers, Neil.

[RCP57]

That's a good idea Neil.

A short video of Dozer number two on the move for the first time. I still have much to do!

Don't know if it helps but all I did on my d11 drive sprockets was drilled the holes and pressed the bolts in. Had to use tweezers to hold the bolts vertical then just pressed them in. Or uhh maybe Santa has room on that list for a printer? Lol. It looks really good, the movement looks strong and fluid. Great job!!

[RCP57]

That's what I did on my KW build as well. Interference fit is way better than threading all those tiny holes when the bolts are just for show! On the dozer I just drilled all the holes to the right size and glued in left over pieces of filler rod. Once the glue dried I used my 6" disc sander to make them all the same length. Cheaper than using bolts and it looks nearly as good I think.

Hmmm, my list for Santa already has something really expensive on it so I think I will just try to save up for the printer.... I do want one though...

[doodlebug]

Anybody looked at the Dremel printer at Home Depot yet?
Cheers, Neil.

I have been working on these steady lately trying to finish them up. Dozer #1 finally got a paint job and nearly all the track and blade parts are finished for Dozers 2 and 3.





I made up this fake cylinder for the right hand side while the left is rigid. It is spring loaded to allow some give while tilting the blade. The result is some pretty serious articulation without binding.





1 and 2 sitting side by side. I found some paint that matches pretty well.

Nice job reg, works really well, how do like those motors vs servos?
