Whew, glad for that. LOL
Now that I've got a set of rear wheels, I just had to set up a rough mock up to see how its looking. The whole chassis will sit taller once the rear axle is mounted and front leaf spring is made and installed. I'm liking how it sits at this point.
Brad.... I am loving this mock-up. It is looking killer!. Nice work and it sits perfect.
Your model is progressing nicely and looking good.
Could you tell us a few detaails about how you're doing the front end? Styrene or brass tubing, how about the knuckles. I love to see nice suspension work on our hot rod and drag models.
Love that mockup!
Hi Michael ~
Thanks for the comment. I've always required working steering on all of my builds and since I like altereds and rails, I've had to make them out of tubing since they show. I used aluminum tubing so I can polish it up to look like chrome. When I built my Altered Ego Fiat, I was asked about the steering so here's the diagram I drew up explaining how I do it. Its fairly detailed and takes some time but really worth it in the end.
Ask if you have any questions.
Hi Brad, now we're talking. I was hoping you use brass, how in the heck do you attach the spindle to the knuckle?
Excellent diagram by the way. This is what I'm looking for.
I attach the spindle to the knuckle by drilling out the vertical part of the knuckle and use a piece of 0.035 piano wire with the burr still on it and pushed in from the inside of the C of the knuckle. Apply a small amount of Zap-A-Gap. Once dry, I attach a small piece of 1/16th tubing with a small sleeve of 1/8th tubing up against the knuckle for more surface area for the Zap-A-Gap to hold better.
Hope this helps.
Whew. Front axle is done with the exception of the leaf spring which I'll work on tomorrow. Pics in the morning.
I'm back with those promised photos of the functioning front axle.
I did this one a bit differently than in the drawing by using R&B stainless steel tubing for the steering arms. They were filed at a slight angle with the side of a cut off wheel on my Dremel Stylus. I 'm so thrilled with how these came out, this is how I'll do these from now on. I'll get a close up picture of the bottom of the knuckle so you can see what I'm referring to.
Thanks for your interest and following along. Comments welcome.
Brad, nice work. Keep it up. look forward on some of this project.
Thanks Stephen. Been working on the rear axle trying to get a rolling chassis before I call it quits for the day.
Yes Paul. I'm going to use the one from the Double Dragster kit with rear disc brakes from the Piranha kit.
Really cool build Brad, I like this car a bunch. Incredible work on the front end.
Brad, that's sick.
OK, spill the beans, tell me what size nuts and bolts? Are the nuts 00-90? I'm trying to weed my way through all kinds of websites for mini hardware options. I see some nice things, but I'm not sure of the scale, and I'm confused about sizes. I prefer metric system.
Can you tell us about the rods ends too?
The work looks fantastic!
Just one more though, is the front supposed to be non sprung? Is the unit mounted backwards? (Tie rods to the front?)
PS: About Zap-A-Gap, I have to laugh now. I'm going to my local Hardware Store (I live in Germany!), and telling the dude there, in German, "I need some zap-a-gap". Like the German word for a bra is; "Stoppen-Z-Floppen".
OK, spilling the beans Michael. Here's all of the items used on the axle:
The rod ends are from RBmotion.com - part number1501
The stainless steel tubing is RB Motion too - part number 1542
The bolts are from ScaleHardware.com - part number THRB-05-S
The washers are Scale Hardware items too - part number WASH-05-S
The nuts are also Scale Hardware - part number THRN-05-N
The aluminum square and round tubing is from the LHS and I imagine its K&S.
You'll need to drill out the rod ends a bit with a number 76 (.020) drill bit for the nuts to fit inside them.
The straight axle will have a traverse mounted leaf spring over the axle that mounts to the frame hanger once I get one made or source one. I could have sworn that I've seen some photo etch leaf springs online in the past but I'll be darned if I can find them now. Guess I'll have to make my own from either printing plate or sheet aluminum. Let me know what the sales person says when you ask for some Zap-A-Gap. LOL
Thanks for the kind words Paul, Gene and Michael. They're really appreciated.
Thanks Brad, I've saved the info!
By the way, I'm at a front end suspension right now, but I bought the wrong kind of solder for brass profile pieces.
Also, here a real secret type of tip for aluminum in scale. My old business backup disks, I have a ton of them left over, excellent stuff!
I just made a motor plate for a 32 Ford with the stuff, great!
Thx Michael. Yea, I've used that stuff before. A little stiff but works great. I really like used printing plates the best. They come in a variety of thicknesses.
Beautiful work Brad!
Thanks Darryl. Glad you're following along.
As mentioned earlier, here's a couple pics of the underside of the knuckle.
These really show how clean the stainless steel tubing works out.
Brad, is the tubing on the knuckle also glued? Zap a Gap?
This is really good stuff, thanks for the details. Very clean and well built.
Yes the tubing for the spindle is glued with Zap-A-Gap. I think you're more likely to find Zap-A-Gap at the hobby/craft store than you would at a hardware store but I've never been over the pond so don't know how things like this work. Where do you get your modeling supplies?
Here's a couple of shots of the chassis mocked up at this point.
Engine needs a final sanding then ready for paint. Waiting on my blower pulleys to arrive before doing this though. Need to work on fabricating the leaf spring and mounting system soon.
Good news, Zap a Gap is available in Germany.
I checked out the reference numbers on the parts used, so I've zeroed in the sizes.
Things are looking good so far.
