1950 Kenworth Needlenose
Here's a new project I'm going to start building. It's a 1950 Kenworth needlenose. I figured I'd mix it up a little, and work on this one, in between working on my Wedico Peterbilt, which has been slow going. This build should go a little quicker, for a handful of reasons, but it will not be without it's own set of challenges.
http://i1159.photobucket.com/albums/...ps48014ae0.jpg To start with, it's a 1/16 scale model, which means it's quite a bit smaller then my Wedico Peterbilt, and a lot smaller then a Tamiya. I took a chance when I bought the cab. I wasn't sure just how much smaller it would be. The plan was to fit it to a Wedico chassis, but I knew it wasn't going to be a simple bolt on affair. http://i1159.photobucket.com/albums/...ps9c5b4e7d.jpg http://i1159.photobucket.com/albums/...psd05c1426.jpg http://i1159.photobucket.com/albums/...psdd61dcdf.jpg http://i1159.photobucket.com/albums/...pscd0d837e.jpg I borrowed the chassis of my Peterbilt, just for some mock up. Yup, it's not going to fit that easily! Both the front driven and non-driven axles are to wide for the cab. The chassis is also to wide. The cab doesn't even sit down properly, but if it did, the rear axles would fit the width of the cab pretty decent, even if they are a little wide also. Hmm, what to do. http://i1159.photobucket.com/albums/...ps0fe7d7f6.jpg A driven front axle is out of the question, and I don't want this build to get to complicated, so I thought I'd try the lift axle I built for my Peterbilt, under the cab. I narrowed this axle up quite some time ago, and low and behold, it fits the cab very nicely. Don't mind the super singles. They won't be staying for this build. http://i1159.photobucket.com/albums/...ps6ad16a12.jpg http://i1159.photobucket.com/albums/...psa57e795b.jpg A little more playing around to figure out if the ride height will be acceptable, and if the tires are close to the right size. I thought at this point there was a good chance it would work all right, so I went ahead and built a mock up narrow width chassis to really get an idea for what this project might take. http://i1159.photobucket.com/albums/...psee47293b.jpg http://i1159.photobucket.com/albums/...ps41cc6dc1.jpg I had some spare parts laying around, and figured I might as well use them. An Osswald front suspension I had on the bench, designed for the Wedico, ended up fitting well. I machined my own front cross member to tie a set of blank frame rails togther too. I have to say it looks promising at this point, but there is still much more to figure out. We'll see how the rest of it comes together. |

The build quality looks very German, in a good way of course!

Re: 1950 Kenworth Needlenose
Thanks guys.
I have a few more photos to share. In order to build a chassis to fit the Kenworth cab, I needed to run a narrow chassis up front, but standard width in the rear, so that all the Wedico components would fit like a stock truck. I was not going to narrow any rear axles, or build custom ones, so my solution was to make a chassis member that would allow me to transition the chassis from narrow, back to standard width. Here are the photos of the frame member - http://i1159.photobucket.com/albums/...psa647d7fb.jpg http://i1159.photobucket.com/albums/...ps7f528b26.jpg http://i1159.photobucket.com/albums/...ps42120b0e.jpg One solid billet frame member, to connect the frame rails. I am sure it will be plenty strong, so even if the frame rails aren't continuous, I know it won't fail. Like my Peterbilt project truck, I decided to go with a planetary gear box, mounted under the cab. Space is even tighter with the Kenworth, so this will be a big help. I also like the simplicity of having a strong single speed transmission. I machined the frame connector to accept a 16:1 planetary gear box. A 20:1 is identical in dimensions, so if need be, I can switch to one. http://i1159.photobucket.com/albums/...pscc45851d.jpg http://i1159.photobucket.com/albums/...ps0b3d84c7.jpg Assembled, my front cross member, and the frame connector, serve as a good place to mount the steering servo. http://i1159.photobucket.com/albums/...ps2ed38f37.jpg http://i1159.photobucket.com/albums/...psd5cb68ba.jpg These photos are before I machined the frame member 100%. The cut outs for the motor and wires haven't been machined yet, but in these photos, I was mostly checking the fit of the frame rails, as well as the fit of the servo. http://i1159.photobucket.com/albums/...ps3f599022.jpg http://i1159.photobucket.com/albums/...ps6113c4f5.jpg http://i1159.photobucket.com/albums/...ps7e62bdd2.jpg The drag link, from the servo to the steering knuckle will be nice and direct. |

Re: 1950 Kenworth Needlenose
awesome build.
they have you on their website (but you probably knew that.. lol) http://www.allamericantoyco.com/aatc...nathan_rc.html |
Re: 1950 Kenworth Needlenose
Thanks bigdogrod. Yes, I did know that. I guess I better bring this thread up to date then! I planned to go in chronological order, a little at a time, but since you found some of the details of my build, on their website, I'll show the rest here. Not all the details have been shown yet.
I stole the rear axles and suspension off the Wedico Peterbilt. :D I just wanted to check the ride height, and how the truck might look. The frame rails haven't been cut to length yet, so I'm still figuring out how long is to long. Oddly enough I bought these frame rail blanks for the Peterbilt too, but the Kenworth wanted them more! http://i1159.photobucket.com/albums/...ps34b44640.jpg http://i1159.photobucket.com/albums/...psd1abdeea.jpg It's nice to get a good visual sometimes. In the rear, you can see it's sitting a little high. I had the same problem with my Wedico Peterbilt, after lowering the front end, but I've got solution for that already. If it works on the KW, it will also work on the Peterbilt. http://i1159.photobucket.com/albums/...ps421ec2cb.jpg Since mouting the steering servo, I had to mill an opening in the cab base, so the base could sit on the chassis flat. The cab base, and cab have these mounting posts that I also milled off. They would have provided a way to attach the cab and floor together, and also to the All American Toys chassis, but for a model that will be functional, they had to go. I needed the room for electronics, and so I will have to figure out another way to mount the base to the chassis, and the cab to the base. I don't think this truck will have much an interior either. Space will dedicated to the functional bits instead. I do not think the seats will be staying for long. http://i1159.photobucket.com/albums/...psf71b01e0.jpg http://i1159.photobucket.com/albums/...psd468df5b.jpg http://i1159.photobucket.com/albums/...ps0d9d53f6.jpg To get the truck leveled, I figured I would just notch the frame rails, so I could push the suspension bolster higher up, thus leveling the truck out. Not really rocket science, but it did take some time and planning. To keep the strength in the frame, I backed the notched area out with a backer plate. It's stronger now then it was before the frame was even cut. http://i1159.photobucket.com/albums/...ps5c66c79d.jpg http://i1159.photobucket.com/albums/...ps958480e3.jpg |
Re: 1950 Kenworth Needlenose
I wasn't really happy with the Wedico cross members, so I machined my own. I just loosely based the designs off of photos of the real trucks I had seen, and while they aren't exact, they turned out nice. First the area below the 5th wheel. Then the cross member in front of it.
http://i1159.photobucket.com/albums/...psae1f3a16.jpg http://i1159.photobucket.com/albums/...ps7af48385.jpg http://i1159.photobucket.com/albums/...ps57712a59.jpg http://i1159.photobucket.com/albums/...psc84bcc45.jpg Time to drop the cab back on and see what it looks like, standing on it's own feet again. http://i1159.photobucket.com/albums/...ps4a443811.jpg http://i1159.photobucket.com/albums/...pscbfd87aa.jpg I also thought I'd mill a window opening, in the back of the cab, while I was at it. I think Optimus Prime would approve! |

sorry, didn't mean to spoil the surprise..

Re: 1950 Kenworth Needlenose
Bigdogrod, no harm done. The guys at All American Toys asked me what I was going to do with the Kenworth cab, when I ordered it. When I told them, they asked me to send some photos. After I did, they asked me if it was okay to post them on their site, as a work in progress. I said yes. If anything, it will give me a little extra push to try and get this one done before say....summer? :D I can hear some people laughing already! Ha ha.
Anyway, the guys who own and operate All American Toys are really good people. I don't think I've ever talked to more down to earth guys on the phone, or emailed. My hat is off to Patrick and Dean. Good customer service too. I give them credit for keeping it made in the USA. |
Re: 1950 Kenworth Needlenose
Great looking old rig, are those knobby tires staying on the front? Oh and while I'm here are you going to switch those cross member bolts with something like the rc4wd scale head bolts?

Re: 1950 Kenworth Needlenose
That looks great! Too bad it's so tiny... :p Just kinding. It's one of my favorite truck builds! You should be able to finish it by next weekend....

Re: 1950 Kenworth Needlenose
Very nice work Nathan. I wish I had a mill to play with and make my own parts....maybe someday, never know;)
This old K dub is looking very good and very unique. Can't wait to see more progress:) Mario |

I'm not sure about using the hex head screws. They would certainly look awesome! Have to think about it. I do like the socket head cap screws, in stainless too. Makes them look like the polished hardware caps they use on the show rigs, which cover the hex head bolts. Quote:
