Question Wheel opening contours / body prep question

Iím at the stage of the build I dread the mostÖ bodywork. Heck, I canít even use liquid paper without messing up!

In the spirit of doing as much as I can myself (something about the journey vs the destination), Iíll get it doneÖ with your help of course!

Read the DanEC post regarding the topic (Fiberglass body wheel lip body prep) but I still have questions:

What does the ideal wheel opening lip look like on a FIA?

What is the best way to sculpt the fender lips? (Tape an outline, scribe into the fiberglass, ??)

What tools do you use to bring it to the right format? (Dremel, drill, cut off tool, reciprocating saw, router, or?)

From looking at completed FIAs, it seems like quite a bit of material is removed OR huge amounts of filler are added.

Any and all suggestions are greatly appreciated.

Thanks
Al

I just made up a fence for a dremel tool with a diamond cutoff wheel to cut the lip to length. I really like the Shelby lip as it's finished like a wired edge. I'm playing with some tool ideas to try and get that radius now. It I could get a radiused router bit that fits my die grinder I think that would do it.

I've seen reference to the "wired edge" before. Could someone explain what exactly that is. I assume it is part of the aluminum manufacturing process... photos would help.

How bout a vid,YouTube - ‪Fabricating Fenders for a 1934 Lagonda Part II‬‏ note some simple little tools like a fork to put over the edge and form the radius bit by bit. I like those small torches that he uses too.

Something you may want to check, my right rear wheel opening is 1/2" taller than the left, ride height is equal on both sides. Either the body is twisted in the rear or the openings are different. Wish I would have caught it when I was at your stage. Sounds like you may be meticulous, in which this would bother you as it does me.

mickmate, thanks for the reply. Great idea! What did you use as a fence? How did you guide the dremel?

Not sure my hand is steady enough. Thinking a thin/flexible body side molding (like a door edge molding) could act as a guide. Perhaps a mini router would offer easier maneuverability.

Those rolled edges sure are nice. Iím not that ambitious though.

WolfÖ absolutely love your build pics. You are definitely the meticulous oneÖ and thatís a great trait!

Thanks for the heads up. I bonded the body myself, so I hope I didnít mess up. Iíll run a straight edge off the frame and measure the height. All my pre-drilled holes and panels lined up, so fingers are crossed that all is well.

I didn't even take a picture of it, I'll get one. I welded some plate to a nut and a small piece off that. The two planes kept the circular cutter off the edge the same distance. Like a mini router as you'd suggested. I'm thinking next of a fence for the die grinder with a carbide burr and just keep it perpendicular to the edge while I run it around at different angles to cut the round profile of the edge. I could probably have done it by hand already instead of dinking around with tools.

Think you're right mickmate. I'll take your advice!

Looked for a mini router but they all seem too cumbersome for the task. Iíll put down a ľ inch tape guide, switch to decaf and use the dremel or die grinder to bring it down to size.

Thanks
Al
