Very nice work, glad to see you enjoyed your time away.
 

I was actually giddy when I saw that you had posted an update. LOL

Before I'm doing the various holes for the front support to the frame, I began the rear supports for the front springs. They will be riveted over the fist cross member; it was a part which could be replaced at that time, therefore it could not be installed between the frame and the cross member.
The first picture is from a real car; the second picture is showing the base plate for the support; the upper leg had to be bent in a precise location as it is inserted into the frame like a wedge.
This support is also the attachment point for the front brake's cable.

There were some additions made to the LH spring support: the bearing and a fin connecting the upper leg to the bearing. Some minor additions are still needed to complete the first support.
When I drilled the 4 holes at each support, I noticed later to my dismay that 3 were at the wrong place, due to a wrong reasoning! I closed the holes and drill new ones at the right place.
To continue with the positioning of the support to the frame, I had to disassemble it (once more) because I cannot drill the necessary hole from inside, the other frame rail in on the way. Then, with a lot of R & R, the holes at the frame for the support could be done.
When that LH support will be finished, I will do the same on the other side.

Looking good Roger, we'll just keep that little mistake between us 😉

Hi,

My name is Jim Keeler and I have written articles for automotive  and model car publications since 1961. I am an ex Revell model kit company hobby kit designer and was Product Manager of hobby kits for Aurora Plastics.

I’ve been following the construction of your stupendous Continental Mark II and have really enjoyed observing you build your great model car. It’s been of special interest to me because it is one of my all time favorite automobiles.

 

I wanted to ask your permission to do an article for an American model publication.

I would like to be able to utilize some your extensive photos of the construction of the Continental model.

Would you be interested in such a proposition?

I’m contacting you first before I make a presentation to the publication.

I am looking forward to the possibility of doing a story on your amazing project.

 

I am located in southern Utah and my email is:

Thank you,

Both rear supports for the front springs are ready. To facilitate the future assembly of the frame, the supports are soft soldered at the first cross member. All the holes you can see on the side of the cross member are for the rivets. There will be 30 rivets for that assembly, but not all will be effectively riveted because the access at the rear of the rivets is just impossible.
I will do now the recess on the frame rails for the front brake cable; I added a picture of the real recess. I could not do it before because the relationship between the recess and the rear supports must be exact.
On the real frame, that recess is stamped. I cannot do it that way, it will be a separate element soft soldered.

First, I did the aperture in both frame rails and then a modified half cylindrical insert was soft soldered. Not a big deal, but it was needed to have functioning front brakes.
I'm going now further to the front with a small reinforcement which will be installed after the first cross member is riveted to the rails. I'm also attaching a picture from that part.

Both small reinforcements are done; thee holes for the rivets will be drilled with the rails when it will be time to assemble the whole frame which will happen soon.
I also did and soft soldered the large nuts for the front shock absorbers. Two are hidden behind the tower; they had to be attached before the assembly. The rear nuts had to be modified a bit: the rear of the tower should be more vertical. That's the kind of errors which are discovered late and cannot be corrected unless the whole sub-assembly is discarded and a new is made.

Roger that frame is amazing, even with the "errors" that we wouldn't even be aware of if you hadn't informed us 😉

Roger, As usual, your work is beyond the ability to truly express in words.  Just fabulous.

Lately, I'm trying to do on the frame rails all what I can before the definitive assembly. The holes for the engine support, steering gear and idle lever for the shock absorbers are all done; even if I don't have the precise location, those holes should be more or less at their correct place.
There is also another small part added: the bracket for the hood fastener at the front; after the assembly, it would not have been possible riveting that small part to the frame rail.

Another check at the lose parts and the assembly will begin!

The cross members # 1, # 3 and # 4 have been soft soldered on the RH side rail. The small reinforcement at the front is also soldered but the holes for the rivets not yet done. I could rivet # 1 and # 4; the rivets for the # 3 will be fake because I should do about one tool for one rivet and the chance that the outcome will be good is far from garanteed. The rivets will simply be pushed into the holes and soft soldered. The other side is hardly visible. I'm adding a picture showing most of the tools I need to rivet the cross members.
I will do now the same treatment with the LH side rail. The last cross member will be installed next. 
As I stated earlier, the cross member # 2 will be done and adapted to the powertrain/frame once the engine & transmission are done.

Roger were these tools fabricated for this project or did you have them left from other projects. Do you keep any of the tools you make in case you need them for something in the future ?

 

It's looking great.

On my previous models, riveting was minor: the blades for the cooling fan and maybe some on the frame for the Mark II. At that time, it was easy: two bits of bras with a half-moon recess and a hammer.

Here, it's more complex because for most rivets due to the configuration. Therefore, the tools you saw were done for the task. However, it's not a big deal, most tools are done with scrap material and don't take a long time to be usable. I will probably do more or adapt existing ones to rivet the last cross member.

Depending of what the tools are, I'm keeping them or use the material for another task. During the years, I kept most tools I did and finally, I'm never using them again.

Roger as is usually the case, you know as soon as you don't keep a tool you've made you will need it again LOL 😉

With the exception of the #2 cross member, the frame is technically finished. Of course, there will be some holes to be drilled for various accessories. As I wrote some time ago, the location of the #2 crossmember is depending from the end of the transmission as the cross member is supporting it.
As you can see, all rivets are in place, some are just soft soldered to the frame as creating a tool specific for each rivet is a waste of resources. Initially I had 200 rivets. When the second cross member will be finished, I will have just 22 left!
If I'm comparing the frames I did for my other models, the one for the V-16 is twisting easily. Sure, when the missing crossmember will added, that tendency will be reduced. This could also be the reason why the rear of the engine has supports attached at the frame, plus the ones at the end of the transmission. Those multiple engine/transmission cushions were probably also a help to add some torsional rigidity as on the V-16, the second crossmember is located about in the middle of the frame.

What's next? I think it's now a good opportunity to begin the engine, it's will be so easy to do!

OK Roger - how many ended up on the floor? 🙂
