I've seen a 785 here next to a D11 but nothing bigger down here .

My buddy up north at a gold mine. The electric version of a 797

Wow!! And thanks for the mail pics Mario, once I can get accurate frame geometry and dimensions I think I'll be set for building. Not going for perfect scale but for function.

BOOO! It's late but happy Halloween!! Says the hairball with fangs and claws!!

Got some more mold making silicone, just got done the bottom pour. No vent holes or casting holes. I am going to cut them in after silicone has set. More simple, will just use a sharpened tube to cut them.

The two parts, have to cut some pour/vent holes

I confused the resin and thought I had plenty of time to mix, degas, take my time. When I was vacuuming I thought it appeared to be getting rather stiff and then realized I just wasted $$ by taking my time. !!! Yup another part for the recycling bin!! Well a glob of something!!!

And the correct timeframe for mixing, degrading and pouring. I placed a weight on top of mold as a precaution of deforming.

Re: Great Dane excavating co.
 

Since you're building a "Kitty" why didn't you use the pink for your tires also?

On a serious note, how long are we waiting to see if you are a hero or a zero with this process? Keep in mind you are already my hero as previously stated...

Re: Great Dane excavating co.
 

I'll leave the pink kitty jokes alone! Is it soup yet? We want to see a tire!

So what is the working time on the rubber?

Re: Great Dane excavating co.
 

Well that depends on if I am willing to be a zero :). Lol!! 2-4 hours on demolding time so hopefully tonight yet. I already know I didn't add enough pigment. It is pretty concentrated and too much will weaken the resin. So I may have been on the skimpy side of black color. And I do t know about the possibility of trapped air. One thing I did find out is if air bubbles are a problem (trapped pockets) to apply a dusting of baby powder. It's just me but I learn more after I've done something. I grew up tearing things apart not putting them together. So my lack of human evolution leaves me with reading the directions after its together. Ha know when it doesn't work and ha have leftover parts wondering if they are extra or if they might actually be needed ��

Thanks reg!!! So be seeing you in August !!

Re: Great Dane excavating co.
 

And the wife got some pestering with the leftover mold rubber. Once cured it pulled out of the bucket and its squishey and stretchy and ,,,, Oh yea I guess I should leave it alone also :)

And on another side I went to Taco Bell today , great tacos today ;)

Re: Great Dane excavating co.
 

Well if the tire thing doesn't work at least you know you got something else you can mold!

Re: Great Dane excavating co.
 

i missed something why dose your wife want to play with pink silicone shapes??????

Re: Great Dane excavating co.
 

Couldn't wait, had to pull it out.

And the pinch test, duro 60, wanted them to be hard enough not to roll and stay put.

And the bad side. I have a better idea of how to eliminate the little bubbles. They are from pouring the resin into the mold. I need to pour it while slightly angled, roll a bit, the baby powder, and a freckle more experience. Second one will be better!!
http://i1357.photobucket.com/albums/...ps639sd4fe.jpg

The color is off, more pigment. And it is shiney from some of the oil in resin and mold release. Also need to let it cure longer to guage the true hardness before I get more to make the rest.

Re: Great Dane excavating co.
 

Your my hero too R dub. :D.

Congrats on your very first Cooper tire ! :cool::p:lol: I'd call that a complete first run success!

How much does the baby weigh?

Re: Great Dane excavating co.
 

Thanks Mario!! I wish I would have gotten the color right, could have used this one!! Will make a good flatbed load for the trucks. 4 pounds per tire!!! She's gonna be a heavy off highway truck for sure. 24 pounds just in tires!!! Definately going to have to get the transmission right. Planning on using planetary gear motors hidden in the axle. Might even have to make hydraulic steering too!!

Re: Great Dane excavating co.
 

its a bird its a plane its super cooper!!!!

Re: Great Dane excavating co.
 

Hahahahahahah !!! Got me to smile!!! I AM SPECIAL!! In my own way!!! Lol!!!!!!





Jacka$$!!!! Lol!!

Re: Great Dane excavating co.
 

It don't take long and the tires aren't black anyway. More of a grey tone afterawhile. :)
Hydraulic steering might not be a bad idea for this beast......so, handmade dump cylinders, soon to be steering.....your almost there! All that's left is make the worlds smallest nitrogen charged suspension cylinders!:eek::D

Something tells me the motors are gonna run the same price as the mad cat motors? :rolleyes::eek:

Re: Great Dane excavating co.
 

Wow, that's just super:bounce::bounce:! The tire looks OK too I guess.:p

Seriously, that looks fantastic for a first attempt! It's too bad the materials cost so much because I'm sure if you built a few more they would be perfect before too long. Keep up the great work!

Please note that I have refrained from commenting on certain posts....

Re: Great Dane excavating co.
 

That would be perfect , I hear it gets a tit bit nippy up there!!
