.910" by .875" by .063" front brass chunk and tongue tinned (both sides). Then I etched alignment scribes on both tongue and chunk with my calipers for alignment. The 2 degree tilted Chicagoland steel tongue has notches for easy eyeball alignment, and a couple grooves that make perfect slots to lay small lengths of .032" solder. A precise and perfectly thought-out product for scratchbuilders :good:  :good:  :good:  I positioned it with alligator clips, bathed all in acid, turned off my central A/C and ceiling fans, and hit it with the minitorch. Nailed it, easy  :) No brag, just fact  :crazy:

Mini-motor box and .063 plated Swiss wire rails tacked in place. Now the gears, jig wheels and jig motor came be removed, cleaned up and set aside

Braces, strengtheners n whatnot, joints finished, rails trimmed up front

Next challenge is, I have a narrow body and not much room to make a fairly heavy car. I think a shakey weight right in the middle will help a lot ……...

What maximum width will your Lola T70 allow without altering wheel wells, as per the rules? Close to the allowed 3"? Any surprises/complications in those rules? It's coming along nicely!

Thinking ahead, have you thought about what you're going to do for paint? Such as color(s), if your're going to in-house it, 2nd party it, etc, etc. :)

The Revson car was white, the Tamiya body is white, as soon as the extra stickers arrive from my friend in Bulgaria I don't think I need much paint, do you?  :)  :shok:

Number 2 Novus is all I ever use, that and a set of fine sandpaper. Like this. Not sure where I got mine.

Handy if you want to remove a mold line.

Micro-Mark has carried Novus in the past, perhaps they still do. Some hobby shops may carry it also,

I got my Novus from ePay, the 3 bottle set with a polishing cloth, for about $20.00.

eBay currently has the 3 bottle sets, plus the rag & free shipping for as low as $11.50. The bottles could be smaller than yours, but there's plenty to polish at least a couple kits. Does Novus have a shelf life? 

 

I would check Hobby Lobby too.

Mine are the 8oz bottles. The cheaper ones I saw were the 2oz bottles.

Rear weight deck is .032 X 3/8 X 2 1/2". It's as wide and long as the limitations of the rules will allow with this body n chassis

 

IMG_2832.JPG

 

Since I named my mid-section shakey "Fowler Platform" it's only fair to name this one "BP Platform" (boom)  :laugh2:

.055 connecting wires do double duty by strengthening up the rear of the axle tube nest with an .047 cross-connector wire and they will allow the BP to wiggle a little once I install twin pieces of 3/32 tube

BP Platform complete. Little bit of lift/wiggle waggle/left/right, but no droop

FYI: There won't be a space for this class of car to run in the D3 Hardbody Nats at BPR in October, and there will most likely be a "2nd Chance" Short-track Nascar Enduro in November. So depending on when it can get done and out here, it can be tested and run in one of the Hardbody races before or after those two months. It's really looking good.

Thanks Eddie. It's coming to you the moment it's done.

 

Next step is front wheels/front axle assembly. Eddie, these Pro Track retro hard fronts are hard as a rock. I see everybody uses them at BP. Has anybody tried re-rubbering them with hard Wonder Rubber and coating with nail polish instead?

Most use the hard Protrack fronts, and it's wise to round them off a bit. The exception would be the wider, somewhat softer hard rubber fronts used on the Short-track Nascar cars, where the tires stick out quite a ways past the width of the body. I'm not sure how much of a difference they make. I just assume they're used for the look.
