A little sheet styrene and reshaping remedied most of the discrepancy at the cowl/hood panel line.

More shimming and shoring up to try to true out the tub and body.  I added several support ribs to the tub in the side pods and the rear of the side pods are now anchored to the tub with screws too.

I designed the wheels for it in SolidWorks.  Because seven spokes…  They will be a combination of 3D grown masters and machined aluminum parts.

After I made the front wheel, (different offset), I designed the outer rims even though they will made of aluminum on the finished project.  This way I can use them for mocking up the car.

The inner door panels needed a lot of clean-up. This one still needs more…  Both inner doors mostly cleaned up and with mounting holes added.  I added mounting plates and locking strips to insides of the doors.  Dry fitting.

Thank you!

 

Door hinges "before".
The part that clamps the hinges to the roof didn't look strong enough to hold up to the disassembly and reassembly that this project will require so I reinforced it with stainless steel tubes that will accept the spring steel rods.

This is great stuff.

Seems to be fighting you, but I do appreciate your responses to the challenge and

your tips and "work arounds."

Carry on sir....

Just keep picking away at it...

Thanks, I wouldn't say it's fighting me, I expected these issues and planned for them to some degree.  But it is a time consuming process.

 

The right side door fits better than I expected, but it needs some serious work.
The left side door does not fit as well as the right side, so I will start to rework it first.

Before I can make the doors fit I need to put the center section of the roof in, and that part is too weak by itself.  So first I added the roll cage side bars.  Each side has a 0.062 steel rod for strength.

Finally the roof center section could be cemented in place.  Three steel pins help strengthen it.

After a lot of reshaping by sanding and adding material I got the left door kind of close to fitting the more complex contours of the cowl and bulkhead.  It's just sitting on the body loose.

Then I reworked the right side in a similar fashion as the left.  It still needs more work too, but not until I get the left door to this stage.
 
But the right side is hinged.

I added magnets to the doors and inside the side pods.  These will end up inside the door sill.
 
The magnets allowed me to solidly and consistently close the doors in the same locations.  I did a lot more reshaping and filling and filing.  Still plenty more work to do though.
But it was also time to check the progress with a coat of primer.

It may not look all that different from the last post, but a lot more filling and shaping has been done. 
 
The left door has been relocated on the hinges to make the top gap the same as the gap on the right door.
Both doors operate smoothly and track quite well, and they have been on and off a few times. I started building up the bottom door sill on the left door to box in the magnets and give it a proper finished look.
 
All the door gaps are starting to become somewhat uniform, but it still needs more work…

Having seen a few of these in real life at the many vintage races I attended, I can tell you that when you're done - you'll have a better "fit & finish" than most of the 1:1 cars I've seen!   I can't wait to see the finished product - what an Amazing build!

Thanks Eric.  Yes the ones I've seen (except the over restored ones) were rough around the edges.  I didn't want to fall back on that since this one will be a modern replica and should be a bit better finished.

 

Now that the lower parts of the doors work properly and track consistently with the magnets, I converted the hinge mounting system from screws to magnets as well.  This way I won't have to worry about damage to the outer surface of the roof when it is reassembled after final painting.
The left side hinges were beefed up and drilled for the magnets.  The right side ones still have the holes for the screws.
The slots for the hinges in the doors were widened to accept the thicker hinges and also drilled to accept the magnets.
The door still lines up like before and I can move on to finessing the fit and shape of the body and doors.

The magnetic approach worked so well I went back and re-engineered the side pods to be held in place with only three small screws on the bottom.  All the hardware that held the pods to the tub has been replaced with magnets and the screw holes filled in.  So before I can finish the doors I need to rework the fastening system for the parts they are mounted to.

To eliminate the screws that fastened the cowl to a pair of brass brackets anchored to the tub, I removed the brackets and made new parts to hold three magnets on each side.  Three more magnets were set in recessed holes in the tub and a brass tube was used to help align the set up.  The brass tube may or may not stay… This is the right side just behind the front wheel well.

It used to take me several minutes to assemble or disassemble even a couple of these parts with all the screws I used to get it trued up and properly aligned.
Now with the magnets it only takes a few seconds to completely tear down or assemble all this.  And the doors operate.  Now I think I'll redo the hood the same way.

I received the first set of wheels that Fraxional grew/printed from the SolidWorks files I made.  These are 100% raw as delivered.  Rear parts on the left and front parts on the right.  They are still on the supports and are slated to be used for mock-up only, but I may finish them just to see how they'll look.

The front hood mounting bosses were cut down and holes were milled into them to accept magnets.  1/8th inch steel rods were cut as receivers since a second pair of magnets would create too much pull for that part of the hood.  Plastic spacers center the rods in the brass tubes.  Driver's side is installed. 
Magnets were also installed in the rear-view mirror supports at the cowl edge.

I spent about a half hour removing the supports (like sprues on injection molded parts) and cleaning up the support points on these two rear wheel pieces.  There are no mold lines to deal with on 3D printed parts, but there can be a texture on some areas.  These did not need any attention in regards to smoothing texture out.  The material Fraxional used on these is more like resin than styrene in the way it sands and creates a very fine powder.  There is a mild odor, but it's not objectionable.
A little paint for the heck of it…  I played around with some weathering/chipping techniques to make it look used.  I see by the fit of the tire I can go wider with the rim.

I reworked the lower nose section that holds the driving lights and stone guard for the radiator.  It fit OK, but not positively.  I used a combination of sheet styrene and removal of some material to make it fit. 
The junction boxes for the lights house magnets in the hood section.

Now that the hood locates to the tub and center body section consistently, I reshaped the surfaces where the hood meets the cowl.  I took off a good .030 - .040 of material on the upper surfaces and did a lot of blending.  The white is the sheet styrene filler.  Not done, but good enough until I do the same to the doors and side pods and center section.

I started reworking one of the forward bulkheads/core support.  I drilled out the duct openings molded into the part and added ducting and supports on the inside so it can be installed without the flexible cooling ducts.  The elbows won't be seen when it's assembled, but I didn't want the intakes dumping into an open space.  I also shimmed the edges for a better fit.

The A-Pillar sections of the doors are inherently weak, and I could see with all the heating and bending some fractures were appearing.  They would have broken well before I could get to painting and if they broke it would affect all the fitting I had already done.  I bent some .061 spring steel reinforcements that fixed the arc to closely match that of the A-Pillar along the windshield.
The left door.
The right door.

A lot more sanding and shaping was done to the doors and roof after the doors were set in their frames and hinges and reinforced with steel, (way more than the hood received).  I added a few thousandths of an inch of material around the windshield and center of the roof and removed and added more elsewhere; as much as .030 was removed (at the bottom of the doors) in addition to what had been done previously.
The door panel lines are getting trued up and both doors operate well.
All the holes I drilled for threaded hardware have been filled too.  Since the primer has been sanded off much of the material used to reshape the doors and other parts is visible.  Clearly more work to do… but a lot of progress so far too…

I started making the shifter and the linkages to connect it to the shift shaft that ultimately feeds into the transmission.  All brass, hand filed and soldered.
At this point the shifter mechanism actually is functional, but will likely be "frozen" in first or neutral later.
