I said I would address the guide issue, so here goes. Many of you might not mind the guide hanging out in front of the car, but it drives me crazy! :naughty: I like my cars to look as realistic as I can. not that I don't fudge here and there, but this one just don't work for me. This is the guide as comes on the chassis.
Strip all the front half down,and get out the dremel or file either will work. I'm lazy, so I use the dremel and milling bit to remove the shaded area.
We are going to add a piece of brass tubing at this point also to strengthen the axle supports. I use K&S 8128 1/8" inside diameter tubing for this. You must ream out the very front axle hole, as we will remove the rest during the chassis cut down I already shown.
Solder in a piece of tubing that fits whatever guide you want to use (I use the slotting plus deep wood guide), and remove the excess brass.
shape the remaining guide tongue to allow as much travel as you need or want.
The new mounting of the guide actually reinforces the pivot area, and keeps the load off the pin.
