Default Chassis CA'ing who does and who doesn't ?

Hi,

I have on my last few kits only the chassis not the top deck or shock towers as never seen the point, just got a new kit hate doing it, does it really do anything apart from slowing me down from building my new kit

Thanks.

After a hard asphalt season, I can certainly see where CA'ing the edges of my chassis have paid off. One I did, one not. Both have the normal "asphalt scuffs" on the underside, but the un-CA'd one has some areas on the edges where it appears to be delaminating.

I have several new chassis for carpet season for my TC and 12th cars. I have sanded and CA'd every edge. I don't see much reason to do anything else other than the main chassis plate, but to each his own.

I find that it takes less than 10 minutes to sand and wash off the carbon dust. I use the q-tip method to apply the CA.

Use thin CA. Twirl the q-tip tightly. Apply 5-6 drops of CA to the q-tip. Press the q-tip onto the carbon edge and twirl while sliding down the edge. Depending on the humidity level, you may or may not be able to get all the way around the part you're doing. Once the q-tip starts to fume and get hard, it's all over...DO NOT touch it to the chassis or it WILL stick! It usually takes me 1 q-tip (2 ends) and 10 drops to do a perfect edge...every time!

I've also recently taken to painting the edges. After the CA treatment, paint the edge whatever color you like, allow to dry, then CA again. Looks pretty trick.

Your mileage may vary.

On another note, I've seen 12th cars that have nicks on the chassis plate grab carpet and cause bad things.

For me, CA'ing may not be necessary, but it's cheap insurance, and I need all the help I can get.

I've been running CF chassis cars for about 15 years now.

The advancements that have been made in CF plate manufacturing and the cutting methods used are truly amazing and beneficial for the end user. Today's water jet, laser cut or low loss milled chassis don't suffer from the amount of "edge trauma", if you will, the older router-cut chassis did.

So, with a high quality chassis, CA'ing the edge is probably a wash. Chances are the chassis will last just as long unprepped in normal circumstances as one that's been sanded to perfection and sealed with CA.

That said, I still CA the edges, even if there's no measurable benefit, for 2 reasons. First, if there is any possible benefit, I'm covered. Second, my cars just don't look "finished" to me without it.

True. If all your cars do is sit on the shelf (or go straight to the For Sale forum), don't bother CA'ing them.

I still do mine, I always thought it was needed to finish a chassis.

Painting the edges looks very nice as well. Its extra work but adds some nice bling to your ride for sure. Here's a link to some pics of my old 12th scale.

If anything I seal the edges just to paint them

Have never done it, have no intention of doing it.

Quality carbon should not have a problem with delamination. CA won't make the slightest bit of difference to impact damage or heavy scuffs. More to the point, some of these carbon parts require the edge for a good fit, CA will conceal that edge.

The owner of my local track said to not CA the edge of my 12R5.1 because it would tweak the chassis. He wasn't sure if loctite would tweak it or not...

Would rather have colored chassis's like silver, green than waste time making the sides shiny
