Has anyone tried drilling a CF Hatch? I wanted to put a spoiler on a CF hatch. Would the hatch be able to support the weight? Also how easy does CF crack when drilling into it?

 

That would be tricky. You would need a steady hand and a set of very sharp bits. If I was to attempt it, I'd progress to a 3/8 hole with at least 4 bits at an appropiate RPM that comes from experience. Iv never drilled CF, I dont think---- and someone correct me if I'm wrong, but afterwords I would seal the perimeter of the hole with fiberglass resin applied with a toothpick maybe to stop a run from moisture than would lift the gel coat.

I dont know how this would work with CF, But in some tricky materials, I have drilled a smaller pilot hole, clamped a tapered punch in a vise gripe, and heated it red hot, then pushed it in the hole til I achieved my desired diameter.

That works well with rubber or leather, plastics (dash penatrations)

 

hm maybe use a drill which is used for wood work
and maybe use first a smaller diameter then and then the diameter u need the hole to be

 

You might PM. Chebosto on this.

 

Note; You may need to add bacing under the hatch to support the wing.

 

What wing?

Jim

 

Most CF hatches cannot handle the added stress and weight of bolting a wing to them.

 

unless u create sum sort of support for them underneath. and u would hav 2 use a very fast drill bit to avoid cracking it

 

I was thinking a CF Nismo (Seibon) wing on a CF hatch.

How strong is the Seibon CF hatch?

 

You'd def want some bracing.

 

yeah, you will need some bracing on the underside of the hatch. The hatch itself is strong, but the Seibon NS wing is decently heavy but it can be done.

 

LOL, I see you beat me to it. Honestly I would just do one or the other, but it looks like it could be possible with the right modifications.

 

I don't know if it would work for CF but it works well with fiberglass, use a step bit (unibit), it makes clean cuts without tearout.

 

Maybe reinforce the area where you plan on drilling with some fiberglass mat and resin on the bottomside? The main thing you need to be worried about is the wind hitting it at high speeds or greedy thieves that just walk by and rip it right off. Just some food for thought. Best bet would be to talk to Seibon and ask them since it's their hatch.

 

If I were going to do it, I would do some sort of metal bracing.

 

I dunno, I want to do it. But then again I don't wanna risk cracking/breaking the hatch w/ the extra load.

 

I'd say just go with that hatch. It looks so clean without a spoiler..
