I will be getting back to it soon. I have to subdivide sections and build to test. :)

Thanks, but I build my models first. That way I know it is can be built, and how difficult it is. One problem is it takes a couple of hrs. a day checking this forum to make sure things are going good. I also have a family and a very full life so models are kind of on the bottom for me. That's why I "Moderate", it is the one way I can contribute when I am done with the other stuff I need and must to do. :)

Believe it or not, I have been working on my '73 M.G. Midget today, positioning it for the restoration of the body shell. I am pooped! I will get to this. With Summer here, I tend to do the "real" vehicles first! I haven't forgotten it though. I just need to do some test builds, primarily the front suspension, and frame, to make sure it is the way I want. :)

Oh, boy, Mentor, I wish I had a third of this mechanical knowledge... Mechanical stuff has always been an unreachable domain for me...

This is a trike I made a few years back for fun. It cruises easily at around 18 to 20 m.p.h., if you are in good shape. I made it from .050" exhaust pipe and machined the rest of the parts, including the hubs as I needed them to mount the disc brakes. It has an air shock in the back for suspension, so it is quite comfortable. It was made from mostly scrap tubing. :)

Why, I'd never...

My friend and "Mentor", I could NEVER EVER, EVER do something like that...:cry: Please, don't get me wrong, it's a beauty, it's just me being completely unable to build such a beautiful piece of machinery, however simple it is.
On the other hand, if you want to talk about nautical cartography, or electronics...sign1sign1
Congrats on a fine, well-built bike, or trike, as you said it yourself.:thumb::thumb::cool::cool:

I am an electronic technician, but for some reason, I think you probably have me out gunned there. I had a T.V. repair shop for almost 10 years and also did some audio repair. I have designed some speakers. The last pair were tapered 1/4 wave tubes with an Fs of 29 Hz. 6 feet tall, 12 inches wide, 14" deep at the base and 12 inches wide and 4" inches wide on top (6 feet tall).

I have also made a few pairs of Electrostatic speakers. These are tricky to manufacture but I have developed a good technique. Not cheap, but Electro-Static speakers are very expensive. I used Lincaine pattern aluminum sheets as the stators and mylar doped with graphite as the diaphragm. They were 4 panels, 2' by 3' each and around 5/15's of an inch thick. I used a Carver Cube with around 200 Watts per channel and thee were a current source that could handle the capacitive feedback without overloading. The step up transformers gave the final voltage around 5000 volts referenced from the high end of the secondary winding. No current, lots of volts. Ohms Law.

I have a nice collection of tube amplifiers, some are highly sought after. My WScott LC 290, with matching tube pre-amp and tuner works flawlessly. I also have a pair of 1969 Wharfedale Variflex speakers. They each have around 30 lbs. of sand in them. Those crazy Brits!! :)

Sorry, did you say some of the speakers were 6ft (1.8m) tall? The SPEAKERS?
Do you take apprentices? I'm really interested in the job! Besides, I would improve both my mechanical (none) and modelling (some) skills... And you would get your personal assistant/paid slave. Win-win situation!

Go to this website. Folding speakers is not good, to get a full 1/4 of the waveform you must build tall, and have a port to re-enforce the lower frequencies in-phase at the bottom. These are not enclosed cabinets.

, this website will give you what you need to make speakers that sound like they cost a couple of thousand dollars but can usually be built for around $250.

My "Mentor", the site seems a lot interesting, with a lot of Mathematical theory (which I'm very fond of), but I unfortunately can't dig into it right now. I'll save it for later, right? Thanks for your comprehension!
 
Nice job on adapting a simple body design, for high detail. I was wondering, in looking at the beginning posts, how you would work out the suspension geometry. You are correct, early model Ford suspension was used for many Hot Rods, back in the sixties to early seventies. Only one problem with that suspension set up... it isn't all that stable at high speed... Hence the move to "modern" suspension, (upper and lower control arms, pioneered by Indianapolis and Formula 1 car tech) that is lighter in weight, and far more stable. Car Kraft Magazine, did an article, on "adapting" older bodies and frames to the newer suspension tech, and the positive benefits of it. This was particularly of note, to fans of older Chrysler Dodge vehicles... which used older, heavier and less responsive torsion bar suspensions. New suspension tech, let their vehicles handle more stably in the turns and hard corners, allowing a safer (and higher performing) road experience. Granted.... this doesn't look at all "old school" but is still visually exciting. Best of all? No frame member running right underneath your radiator bracket... and no transverse mounted leaf spring. This also decreases the "ride height" of your Hot Rod... and lowers the center of gravity. This is just a thought.... because you've already done so much exemplary work to this 'Rod... I'm enjoying the concept's development. Body design is flat out gorgeous...and reminds me of the Cord...just chopped and channeled.

I was actually thinking of making a Ford Mustang II type suspension, easy to stamp it out, as I like that front end, but I went wrong somewhere, so I put it on the back burner. I am considering making a tube Nascar type front end and go from there. I am restoring a real car now (M.G. Midget), so this one has to wait for a season or two, till late fall or Winter. :).
