But if you use wood cleats say 1”X1” at the joints there’s plenty of area to screw to. Back off on your sanding pressure if the board is flexing. Let the sandpaper do the work.

Hey Denny,

I drew a pic, for you

See how I was able to use the (2) "stacked" pieces of 1/2" MDF to form a nice round-over-curve

I'm using this compounded-curved, round-over concept, all along the perimeter of the sides

 

[Functional Artist]

What? Wait! I'm gone for a coupla days and yer on to another project?
Has the paint dried on the last one?

Hey T,
Um...yup...I'm am

No Rest for the Wicked

I've been alternating between towing, putting a roof on our home & "my art"

Installing the wooden strips

Lugging 16' panels

* Notice the hole for the vent pipe?

Last panel

** Working on installing the "caps"...now

Now, it looks like this

Right body side mold & flat panel covered in (2) layers of 1708, the next morning

* The body side panel is marked for trimming
...which helps with de-molding

Here's the flat panel

So I will ask the question on everyone's mind: Why not make a fiberglass roof? They call it combining your passions.

 

[Wicked_Daddy]

So, A metal roof goes on OVER the existing composite shingle roof by mounting it on wood spars? Didn't know that.

Nice fiber work. Anxious to see this finished!

I have an entire roof from 1890 in my attic...

Hey WD,

Yup, "if" the existing roof is only (1) layer
...Ohio law only allows (2) layers of roofing...at a time

The wood strips have several purposes

1.) the strips "space" the steel panels above the roofing shingles
...so, the shingles can't abrade the finish off of the backside (like during thermal expansion & contractions)

2.) the strips get screwed down, with 2 1/2" screws, right into the rafters
...& then, provide a nice-n-wide "nailer" for screwing into, when installing the panels (ta make nice-n-purty lines)

Thanks

I'ma getin' done...what I can get done
...'cause Winter is a comin' fast

 

[Functional Artist]

After doin' some twilight trimmin' on the "nose" & "tail"

I roughly assembled the left side & right sides
...& the "nose" & Tail" pieces
...using the "overlap method" & a few wood screws

The "nose"
* The floorboard (from the flat panel) is just layed in place, for illustrative purposes

The "tail"

 

[Functional Artist]

Body mock-up with "some" wheels "spaced" ~2 1/2" above the workbench

* Hi Ducky

Um...looks like the rear wheel won't clear the "deck" that will be above it

So, I drew in an extension

Drawing of the original plan

The plan was to make & use a couple of "spines" (made outta (2) FG panels bonded to the sides of, a 1/2" foam core)
...with interlocking footboard & seatback/deck panels (also, made outta (2) FG panels bonded to the sides of, a 1/2" foam core)
...all bonded together & then, installed inside the FG body

Now I'ma workin' with a "new" idea
...ta make a (1) piece floorboard
...that has the footboard & seatback/deck "built in"

I'ma callin' it the "flyin' carpet" floorboard

* This concept should
...be a bit easier to make
...create a stiffer "inner "core"
...& provide more bonding surfaces

** It will bond all along the floorboard
...& to the upper body, in the front & rear too

Your getting faster at this FG stuff.

Hey WTR,

Showing folks that knowledge (knowing what to do) & practice (doing it over & over) builds confidence (I can do this)

 

[Functional Artist]

Hey Denny,

While working on assembling & shaping the mold for the "flying carpet" floorboard, I did a step-by-step description/illustration of my MDF shaping/forming method...for ya

Footboard to upper body junction (in the rough)

The tail (with extension)

Used the router to evenly remove ~1/4" of material

Like this

Then, used the disc sander (w/80 grit) to evenly round it off

Like this

Also, used the disc sander (w/80 grit) to rounded off the rear seatback to deck junction too

Then, used the palm sander (w/120 grit) to smooth everything...nicely

Like this

Now, it's ready for some paint

 

[Functional Artist]

Gettin' dark...so much earlier
...but, got 'er done...Satin white

Magic Carpet floorboard mold...ready for service

• Anxious to see what powers this spaceship.

  Hey WD,

I saw member @Mammoth was using a GTS 11 motor & Fardriver controller combo...like this...on his kart
https://www.diygokarts.com/community/threads/electric-off-road-kart.55075/
...& it sounds quite interesting
...so, I'ma thinkin' about gettin' one

That's a serious motor. 6800 RPM? Wow. I believe an on-board video is in your future.
