Lotus Seven in Seven... - Page 2

A little suspension work to show too. Starting with the kit rear coil-over shocks the spring/shock part was removed leaving just the kit spring perches.

To fill in the blank space I added a piece of aluminum tubing, a short piece of aluminum wire and a coil spring wound from small wire.

The result looks much better than the kit part, and didn't take too long to make either.

What's next...?

Nice update(s). The replacement shocks and spring look nice and are quite straightforward to construct. Just make sure you treble-check the lengths, as sometimes they don't fit into the recess in the plastic as snuggly as you think. Also, I find it helps to makes twice as many coiled springs as I need. I then select the best examples. I find that it is a good practice to get into as it is difficult to get an even coil when done by hand.

Hope that helps,
Kind regards,
Bill

when winding your own springs. If you aren't satisfied with the spacing, find some object to wind through the spring, this will give you the separation that you are looking for and everything will be nice and even.

Thanks for the tips. This one was more of a test than a finished spring. My first one was a bit big, while this one is a touch small. I'm going to use larger wire as well.
Here's more or less where this is all headed, it just needs a full cage. I was thinking yellow accents with the green but the black is very nice too.

The easiest way to create equal-length spacing is to wind the wire around a bolt, interlacing the wire within the lands of the threads.

Up on all four for the first time.

Fujimi rims and XS Tuning brakes meet Tamiya kit suspension parts.
I like the front track now and I only narrowed it 2mm over the rear, I also narrowed each front fender nearly 1 mm as well. The seat has evolved a bit too, though it still needs harness holes and a bit more smoothing.

The above original shot on my monitor, at about ten times normal size, really shows areas that need attention.

Some work on the "Aeroscreen". A piece of thin stock wrapped around the cowl and the deflector from a thicker piece. CA'd in place with a dab of putty to even the contours.

I still need to sand it a little and trim the base.
On to the roll bar.

The rear section of the roll cage in place. Looks large but it is the proper size tube for a racing cage. Next comes the front, I'm just waiting for the glue to set on the front mounts now.

Looking good... the roll cage looks beefy but as you say, on race cars they are quite substantial.

Kind regards,
Bill

Great job on the roll cage and the windshield... amazing. Seem we have to run now 'till the deadline: isn't?

Ferrari TR · 02-26-2007, 12:04 AM

Time for the rest of the cage. I started with the front mounts, added the complicated front bar and the rest just to fill in the space.

I'm not sure what I'm going to use for roll bar padding. Maybe some primer on the big pieces next. Anyone remember who did the CF nose?

Hey man, great work on your roll cage. Can I ask how you did it? I tried making one, and everybody killed me over it.

Ferrari TR · 02-26-2007, 10:27 AM

The cage is out of 2mm Evergreen round stock. I would say the front and rear 'hoops' establish the shape so they should be the best you can do. I kept a candle nearby to just warm the plastic to hold a bend. I'm not sure what else I can add as this is my first cage.

Eero15 · 02-26-2007, 10:50 AM

Looking very good so far!
I like the cage.Are you going to make belts for the seat also?

Thanks, I appreciate it. As for roll bar padding, maybe use painters or masking tape? Just wrap it around the cage where you want it until it's as thick as you want it, and then paint it with a brush? Just make sure you get the edges to line up.
