Chassis wings, AKA: arms, ears, outriggers.
 
If a car with a stamped chassis is tippy, has anyone tried putting tape, or body armor, or maybe tried attaching some teflon on the underside of the tips of the chassis wings as a quick diagnostic test, instead of removing guide spacers?
 
If so, did it seem to be helpful?

Usually, a chassis that is tipping some will "scrape" the track and you'll see black buildup/residue on the wings/outriggers/whatever.

I had a few guys who would add dots on the ears.

They were just "punches" of body armor.

Solder balls will work also.

All the time. Good tuning tool learned from Lee Gilbert.

 

Set the car up a little high, use the dots if car is loose, remove the dots if car is too tight.

I've seen just about every way you can think of of doing this, and tried a few of them myself.

Maybe it was Lee Gilbert who I first recall putting bits of body armor under the tips of the chassis wings, but I don't claim he was the first guy to do something like this.

I've seen body armor pieces or dots, solder blobs, 'dots' punched from the top of the wings, holes drilled in the wings with small ball bearings soldered in, etc.

But what I found worked best, at least on the T-Flex, is described in the following quote from my T-Flex Tome. Whether the same approach will work on more modern stamped steel chassis, someone else will have to figure out.

"When the car goes into a turn and tilts, you want the front edge of the outside wing to touch the track along as much of its length as possible. When looking at the track dirt or grunge on the bottom of the chassis, you want to see it building up along the length of each front wing, not just at the tip.

"This requires a very precise guide flag spacer stack and in some cases it will require you to bend the front wings ever-so-slightly up, so that when the chassis rolls a tiny bit, the wing it's rolling toward lays flat on the track. This works better than having just the tips drag. Having the whole edge contact the track won't tend to dig in and it also seems to stabilize the car better."

Last night I finished listening to the last of the Between The Lanes episodes. I started with episode #1 about three weeks ago, and have listened to all episodes while working on my slot cars.  
 
There have been a few tips that I've found helpful. Ralph said he sometimes puts tape on the underside of the guide in order to raise the chassis to see if it's dragging too much.
 
So, as a quick check during test & tune, or quick fix during a lane change, a racer could add tape to the guide to simulate adding guide washers, or add tape to one or both wings tips to simulate removing guide washers.
 
Freezer tape (extra sticky masking tape) is about .005" thick and is paper. Paper can be slippery. For example, if you find yourself at a dance but you left your dance shoes at home, you can stick masking tape on the soles of any shoes and you'll be able to spin like a top.

I’m sure glad you shared that little morsel with us, Dale. I’ll never leave the house without masking tape again!

In 1997, I saw a sign at the Eustis Civic Center that said "Line Dance Lessons." I wasn't sure I would like to dance but decided to check it out. When I went in, I looked around the room and saw about 30 women and only two other guys besides myself. Dancing suddenly seemed very appealing.
