Wow this thing look awesome! (And heavy) The jet seems capable of making some amazing parts for you so far. Looking forward to updates :D

Wooo-hooo! Looks good and just in time to haul presents to the Xmas tree! I sure like the size of that. I don't think the speed is too bad? I guess you could always up you voltage or change the front sprocket if you thought it wasn't fast enough.



Kerry Christmas KP!

Wo it's alive. It seems to turn all right, great job. With the 5 gallon pail you start to get the size of it. Ed

....I meant Merry Christmas not Kerry Christmas...

DADSGARAGE-truck looks great. Turning radius is good, speed may be a bit slow but can be easily fixed. Have you calculated what the scale speed should be (ft. per sec.)? Keep the pictures coming.

Re: 777 HAUL TRUCK (1/12 size)
 

Wow, that looks fantastic. Steering seems to work just fine even without a rear differential. I cant wait to see this truck loaded to the gills lumbering up a haul road.

Re: 777 HAUL TRUCK (1/12 size)
 

The truck is slowly coming together...slowly.....ALM. would be a much better and lighter material to use for a bigger model like this...some day when I grow up I want to learn how to weld ALM.....:o:)

Thanks.....and yes it is heavy!!! Might be the only thing about this build that ends up being to scale...LOL....

Thanks.....it was nice being able to see this thing move around a bit, even if it is a bit slow, hopefully it will have enough power to move with a full load....I did try it with some weight on it but the rear tires are almost running flat because I only have foam in them now...they need air or more foam,deal with that later....


It is alive...well almost...finally remember to get vid of it...funny how tricky it is to hold the camera and radio at the same time,good thing I wasn't chewing gum...LOL...glad the pail was helpful I put it down for two reasons...get some idea of it's size and show the turn radius. It does seem to turn alright but this is with no load on concrete and no air in the rear tires,I think the tires might be slipping on the rims...one more thing to figure out later....

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks......It does seem to turn alright at this point....the speed thing might be a problem, I do have it geared down now to what I hope will provide enough power when it is loaded...that little motor and gear box has a crazy amount power but it still may not be good enough considering the size of the tires and the size and weight of the truck....should have used ALM....but I can't weld ALM.....more like I just can't weld....LOL

Thanks...it is starting to look like a truck ,not very true to scale but more of a "looks about rightish" build.....I wish the tires were a bit bigger and wider...
I really want to see this thing finished and hauling a load as well !!
(besides I need to get started on the shovel so someone stops hounding me about it....Reg...LOL:cop:)

Re: 777 HAUL TRUCK (1/12 size)
 

This is a really cool truck! Access to the waterjet really helps with correct dimensions and repetitive cuts - and with great accuracy.

I've re-read all the pages and did not see a reference to where to got the inside steering gear sector.?.? Saw the servo info with pinion gear. Did you make the big gear sector?

Anyway, awesome truck.

Have you looked at solid amerityre tires?
Cheers, Neil.

Re: 777 HAUL TRUCK (1/12 size)
 

Hi Ken glad you like the truck so far......yes the steering segment arm is also cut with a waterjet, a 32P internal spur gear is about the smallest the machine will cut and the root section of the gear is a bit off, the reason is the size of the kerf cut by the nozzle which is about .030" so that means the smallest radius it can cut is half that size or .015"...Hope this makes sence...

Here are a couple more pics of the steering gear set up.....a few things need to be done with it yet....I just have bolt in it now and still need to make a better pivot shaft for it etc......

Re: 777 HAUL TRUCK (1/12 size)
 

Sorry Neil, I don't think they will work as they were made for a "hand Truck" not a "haul truck".:p

Those would make some nice 1/10th loader tires if the tread was a little different.

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks for the link Neil...I was looking at this type of tire when I started the truck....a solid tire would be great....but they are a bit too wide, the height is better though...too bad the tread wasn't different because I think a guy could machine off one side to make it narrower..maybe...wish it was a diamond tread......

Re: 777 HAUL TRUCK (1/12 size)
 

Got some work done on the hand railing for the deck...much the same as the ladders...next will be the side railing and the small deck next to the cab....
