Justvto be clear you worked from the outside of the panel? Do you tape it off so it doesn’t scratch the paint? Was it a special router bit or just a standard straight one?

Thanks.

Any chance you have a photo of the guides you used or the router bit?  I have a router just haven’t used it much.

Billnparts. Your louvers look fantastic. Any more detail on how you cut them?  Want to do a red set?

Cheers

If you do send a photo and a description on how you cut it. I have real trouble with engine heat.

I put in a 4 core rad and electric fan and still gets hot.
