Greetings gents, I'm needing to buy some anti vibration tape. Can someone please tell me where and what to buy? Maybe a link?

[Phil Hackett]

Do you mean lead-backed tape?

 

Like this?Lead Tape

[Hot Slots]

Bartos and Mossetti sell it.

[Noose]

McMaster-Carr.

[gsisk1]

Noose,

Can you share the link for what you by at McMaster=Carr? I have looked on there before and seen a few things that would probably work but not sure what part number everyone else buys.

[Richie]

If you search dampening tape there is a thread on here with the McMaster-Carr part number.

[The Sawdust Man]

Try this link.
 
McMaster-Carr
 
Part number range is 1466N11.

Fot those not familiar with the titled item, here's a Bartos chassis with adhesive backed silicone rubber.(the brick red stuff)

[jimht]

Not to say there's anything wrong with the silicone rubber tape but I initially did dampening in the Seventies using duct tape, both on top of and under the chassis, and it still works fine.

 

Call it harmonics deadening, movement limiting or whatever...

 

This was when we were transitioning to steel center section chassis and it was obvious that they were not as "dead" as soldered brass/piano wire. It helped to smooth some of the "twitchiness" of lighter weight chassis.

[NSwanberg]

In some places it is known as BS tape.

This stuff just makes bad chassis just as bad with red stuff on it. Its not heavy enough to effect meaningful change, its not fluid enough to reduce vibration.

Guys that use it effect put it in a specific location so bodys dont collapse when a questionable marshal trys to do their job.

[MSwiss]

Yes, I think a lot of it's use is at the outside edge of the pans, to help keep the lower edge of the body to creep over on to the pan, between the pin tubes.

[Mark Onofri]

I didn't realize the importance of ,as jimht put it, for harmonic deadening. In the case of a car equipped with a jk r7777777,etc. it works as a vibration isolator. I did it the first time because, well, the late, great,TonyP did it. Took me a minute to figure out it's not , like he said, just to keep the body from getting squished when picked up. In this case,as a vibration isolator, it made a lot of difference.

I tell everyone it adds density without mass better than lead tape. That is how it functions with the dynamics of the chassis. Those that use it to limit motion do so because their normal tape is useless.

The cool aid must be extra stiff these days.

[chasbeeman]

Great feedback from most of the group! The motion limiting on the Flexi pans is an area of interest for me. I've seen some guys use the glass reinforced tape for limiting pan movements but maybe too stiff for club tracks.

[Mark Onofri]

Mmmmmmm Kool aid. Hopefully not from Gianna.

Lighten up, your negative commentary is unnecessary.

[Mark Onofri]

It was a joke. No offense or negativity intended.

[Mark Onofri]

Oooooh, didn't read the fine print. Electric Kool aid?

Really? You really said that, Jim?

[Phil Smith]

I agree with David. Given the size, rigidity, weight, relative short length and small amount of force acting upon the chassis components, it doesn't seem likely that any meaningful amount of vibration is present in the chassis.

[Bill from NH]

You wouldn't need it racing FCRs & womps. 

[crazyphysicsteacher]

I agree with David. Given the size, rigidity, weight, relative short length and small amount of force acting upon the chassis components, it doesn't seem likely that any meaningful amount of vibration is present in the chassis.

What some forget is to us on our scale the vibration might not seem much but on the scale of the chassis it can be huge. Just remember how a 1/16" in wheel base or guidelead can change a car. The tape has an effect. While some my not believe so there is still much which supports it.

I agree but when I ran a few borroweed retro cars I noticed some were more "dead" than others and that gave a level of smoothness and confidence to push the car harder.  One was even had brass rails.  

Never really bought iinto the red tape club but it might dampen the spring in a metal chassis.
