Default Tips for cutting front bumper holes

Finally gathering courage to cut the front bumper holes. I bought over-riders from Finish Line. Appreciate any advice from the experienced. I am concerned about drilling an "oval" for the grommet. Knowing I only have one chance, I do not whant to chip the paint, or cut a hole too large. Thanks to all who respond.

Regards,

Default Holes in the Gelcoat

Jerry:
I just put masking tape over the area I was going to cut. I used hole sawblades for a drill. Line up and mark twice, check the measurements and position "Twice" before you drill.
I just made sure I went very slow at a medium speed and took my time.
The holes came out perfect, break the edges with sand paper and you should be fine.
I bought the stainless tubes from Finish Line and I bought their grommets. The ones for the front were oval and the rears round. The stuff from Joe was terrible, cut the grommet in two and glue them. Did that and decided it was a mistake and bought the ones from Finish line.
Just take your time.
Jim

Thanks Jim!

I am just a chicken when it comes to cutting into the fiberglass. Hopefully this week I will get the courage to cut into the front. The back is done, and I am happy with the way it looks.

Regards,

Try a couple rum and cokes first. That way you won't feel bad until the next morning when you see the results.

Thanks for the advice John!

Seeing that you are in beautiful Scottsdale, which I have had the pleasure of visiting on several occasions, and hope to return to soon. And I am looking out the window at the largest Northeaster snow storm to hit the area during the month of April.

I am in Double Agony!

Regards

I lived in North Dakota for years and I feel your pain. We dealt with 40 mph winds and -35 temps. The wind chill charts didn't go low enough to register.

Smile fiberglass holes

Mark where you want the center of the hole and use a long drill bit (12") in your hole saw. This allows you to drill straight on the curved surface. If you drill the 1/4" hole first then you can use a level (and the long drill bit) to see if the hole is in line with the place on the frame that you want to mount too.
I air my tires up and measure from the floor to the location on the frame that I'm going to use. Then I use that measurement to lay out the hole on the fiberglass. Use a common reference point (a wall or chair) to get the side to side measurement.

Thanks for the tip Dwight!

I think I have a long electrician's bit that will fit in my hole saw.

Hoping to find time this week to cut the holes.


Regards,
