Since the beginning of this project, I've contemplated making smaller inner fenders for those who might want to use either the original small HF tires/wheels, or perhaps somehwat larger trailer tires/wheels that might not look right in a huge TJ wheel arch. You don't really want to put the small HF tires in a huge TJ wheel arch:
I'm now in the process of making a master to mold new smaller inner fenders - I'm doing this is at the request of "the company" and I'm implementing it using an idea they had. Their idea was that if the smaller inner fender is sized and shaped correctly, if you were building on a budget, you could initially build the trailer with the small inner fender to use the original HF tires, and then later you could upgrade to the larger inner fenders when you could afford larger tires.
To make this work, the inner fender has to "nest" inside the TJ wheel arch. See the photo below, the smaller inner fender fits inside the TJ wheel arch, allowing for a 1.25" mounting flange on the smaller fender (the flange isn't on the master yet).
So if you had the side panels with the small inner fenders attached, and you wanted to upgrade your trailer to the larger TJ wheel openings/flares, you'd just cut out the old small inner fender along the TJ wheel opening line, install the new inner fender, TJ flares and larger tires.
It's a really good idea and an example of the type of creative thinking I'm hearing from "the company."
Here's a shot showing the new inner fender master compared to the old inner fender mold, just to show the size difference. The small inner fender is about 28.5" radius, so it would fit up to say 205/75-15 or perhaps 215/75-15, as well as looking decent with the 5.30x12 HF tires.
And here's a few photos of the master a little further along, the fillets are done and the sealer is on:
Next step is high-build primer and final block sanding. I'll do the smooth tailgate in high-build at the same time.
