"Welcome Home", Joel. Long time no see. Ditto on how's Norm, been since Lake Forest in '76.

Next I thought you might like to see a picture of my jig, a slate block with two brass squares spread at 1.250 inches. I did not know about this other jig some of you have been using. It looks pretty slick. Also pictured is a chassis in progress - John notice the number 1 in the corner.

It was great to see you a couple of Saturday's ago.
Also, terrific you are posting some of your handiwork here.

how you cut your brass pieces?

Wow Joel, that's one sweet little work in progress chassis !! Very neat brass front piece & motor bracket ...

The motor bracket is coordinate drill in a small mill. The tricky part in accurately drilling thin brass sheet is fixturing it. Would you like to see a picture of the fixture I made for it?

your work is very sano!
and the can motor with pancake comm is a work of art.
ever consider edm the chassis parts and producing kits for sale?
i assume you are using BBs in the axle tube?
how are you doing the gear set? spur solder to axle?

When I make multiple of more than five brass pieces it is done in the mill with the pieces stacked in vise. This makes the production fairly efficient and consideration for selling them as a kit is possible. The main time burden in making one of these chassises is the soldering and assembly.
The smallest OD on a ball bearing that accepts a 1.5mm axle is .154 inches. That would mean an axle tube of .187; too big.
The pictures that follow address the spur gear. As you suggest a TJET gear can be soldered to the axle and this the simplest solution. Or, you could cut a gear from the pictured pinion stock and have a shoulder on it. Or, you could do what did and cut teeth in delrin stock and have a shoulder. The .060 shoulder is accommodated with a pocket on the back side of the wheel. The pitch of these gears are 64.

Indeed the problem with ball bearings is size. In an anglewinder or sidewinder , smaller bronze bushings on the axle helps with packaging.
Hey Joel , did you notice my 2 motor car is wired so the forces of acceleration/deceleration cancel each other out?

I did not notice the motor rotationally detail - good thought. It seems that one pairing of the rotations would shift all of the pressure to one side and the other pairing (the one I think you did) would shift to the opposite front and rear wheel.
How did it drive? You would think with all of those driving tires it would accelerate faster on a straight line. Doug Morris built an AFX along these lines, see pictures below. I had a chance to drive this car; it drove remarkably well. If you did not know it was four wheel drive when you drove it you would not have guessed it.

Joel,
I see the # 1, so glad you decided to take this project on. Can`t wait to take some laps with a pro car of yours. Did you also make the pinion Stock? That's Sweet .
Can`t believe this tread is 5 young. Your work will inspirer me & others to keep Scratch building HO.
Thanks Again for posting & Building A Great Chassis

No I did not make the pinion stock. It is shelf item and a very convienent way to make gears. I used it recently to make a 24/11 cluster gear for an AFX. Would you like to see a picture?

is that the high ratio gear set for the afx? i would like to see it!!!

Like to see a picture? Those of us still building with a 40 year old dremel, files, and steel ruler would probably buy a few!

Joel,
Yes would like to see , also more of your work. Were is the source? Awhile back some one posted a picture of a piece of stock that they said came from Aurora`s Source. That was cool
Thanks John F

The second picture are some spliced together cluster gears. I first did this in 1977 with an Axcto and sand paper, no Dremel required. The two gear pieces are held together with super glue; remarkably I have never had a failure. The middle pictured gear is a splice of a 12th speciality AFX and standard 24th. This with a Tyco 19th crown was my favorite ratio for a magna traction in 1977-8.
The far right pictured gear is a 11/24 cluster, with the 11th being made from brass pinion stock. Again both pieces were super glue together. This with an 18th crown is my best performing ratio for a AFX gravity car.
Pat if you are interested in some 11th gears tell me; I think you can handle the super glue and the stock 24th top gear.

Indeed interested in a few 11t gears, Joel, will shoot you a pm here with contact info. I have a boatload of TycoPro 19t crowns, and 20's from BSRT and Wizzard, the dumb question is where are you sourcing 18's? Must've missed those.

nice Joel,
always wonder how the high ratio gear set was made

Al,
bring them to the BIG SHOt race in two weeks and we can see how they run, I have the Doug Morris cars from last year
