Yeah Rob it was great to chat with you too! Hopefully I can make the drive up there before too long and check out that kitchen you've been using as an excuse not to finish your RC's....

Well now that I know it isn't just my ears that think it sounds like a Jimmy I'll share what it is...

It's actually a twist grip engine noise maker thing that my parents bought for me to have on my first bicycle back in the late 70's. I started looking at it a month ago but couldn't figure out how to fit it in anywhere without cutting it. I was worried that if I modified it too much the sound would change loosing it's "Detroitness" but yesterday I felt that I should give it a go. I had to chop and hack quite a bit off of it so I was a little nervous but I think it sounds great! Of course there aren't any fancy air brake sounds or horns but I didn't have to spend an extra dime on it so I'm happy. I used and old gear motor to spin it, made up a simple adapter hub, and drove it off the spare channel on the Sabertooth ESC.








Thanks for looking!

Yeah well I haven't started hoarding cats, spoiled food or dirty diapers yet so I think I'm OK. I had to look up the grip on the internet before I started cutting. I figured that it was over 30 years old and might be a collectors item...thankfully, not so much...lol

Reg, the sound system is spot on for a Jimmy V12. All you gotta do is figure out how to throw some shifts in there and you got it made.

Wow that sounds great!! I do have to ask if you took a pic of the purring engine sound maker? I new at this but is it possible to hook up to the drive motor with a Parel circuit? Then with each shift it would rev up an idle down right? An as for running at idle tho may need to run an isolated/ dedicated circuit. Nice build!! I plan on reading the whole story tonight.

Thanks John, You probably seen it but I think post 575 shows a picture of the noise maker.

I almost have the lowbed finished. I just need to make up some center caps for the wheels and it's done! I also had to take it for a drive this evening to test out the new tire foams and paint...http://youtu.be/B7A_0q11Z7c

Thumbs up Re: Kenworth 850 Off Highway

SWEET
Okay check out this link I found. It has all the information you need for your next build http://www.vannattabros.com/iron20.html
My grandpa ran a line machine that was mounted on a off highway truck so it was a self powered chassis and he could literally "cast" or throw the grapples right onto the log within like 40 yards and then yard it in and set it on the truck. If you ever want personal pictures let me know. Have fun

Thanks guys.

Trucker_Jo, Thanks for the link! I will have to spend some time looking at all the stuff on there. I don't think a line machine will be my next project but it is on the list and not too far down.

I spent a while trying to get the sound unit to be less 'idling or pinned'. It's a bit of a challenge because the sound unit motor always takes the same amount of throttle for a given rpm where as the truck always varies based on load. I did manage to improve it slightly and I think I am just going to have to be satisfied with how it works. I need to keep in mind that this was something designed for a small kid and a bicycle, not to replicate the sound of an Off-highway Kenworth.

The onboard shot picks up a lot of background noise from the driveline and also it was quite windy here today. I think if the camera was actually in the cab instead of behind it on the water tank it would sound pretty cool.

Thanks for looking

The sound unit sounds great. It is a definate improvement over the first videos.

Now its time to start loading it up real heavy and test those differential gears out with some long steep grades. It looks like a 350,000 pound load figures to about 350 pounds so invite a couple of buddies over and take them for a ride.

Don't encourage me! I don't need to break this truck...I might cry if I do.

I finished up the lowbeds wheels yesterday... Now what?
