when doing a rebuild on the differential, correct wear pattern must be determined for best results. We do not want gear noise or rear end noise caused by improper teeth contact between the differential side gears and the pinion gear teeth. We paint the pinion with machinist bluing ( cheap blue...

JB weld will hold it as strong as the spring in your clamp

Ideally we want the maximum left side weight we can get. Do this first then worry about Rc location. We need accurate left side weight % , this is critical. We can check the rear 3rd link location and correct. Next, we want to use an offset roll center to put more downforce on the right front...

Bolts are for clamping things together. Not locating something. Water will invade and cause rust no matter what you do and how you try to prevent it. By the time rust gets too bad on a shock or strut the strut will belong gone in usefulness. Assemble the bolt and clamp dry and clean and torque...

Limitations on water siphoning yes you absolutely can siphon great amounts of water WITH NO PUMP REQUIRED. This is done all the time on farm ponds. Simply use plastic pipe with cap ( or valve ) on the discharge end and a fill plug at the top most point. Fill the pipe with water. The discharge...

65.5" times 58% = 38" i would wait until you can actually get the 58% left side before final 3rd link change. Yes even 3/4 inch on those hard spec tires will make a big difference when you step on the gas. goood job!

you can not analyze cylindricity with only a size measurement. you must know the form error of both diameters otherwise it is a waste of time.

Go to the smaller fuel cell. You are very close on left side 58%. I would try to mount weight close to polar moment but shift back to try to get 51.5 rear weight. Perfect for 1/4 mile track. Cross wt between 54-57.5% do not get hung up on target numbers. everything in racing is a compromise...

good suspension software will show roll. Shock indicators are good devices to feed back at the track. do not change the weight % until you know what it is now. Do you have scales?

you left out the critical factor of design. How round are each cylinder? you have a 50 micron gap that is huge. How round is each part. This must be known before any assembly, let alone stress analysis can be made and contact area. Try fitting a hydraulic connection in a fracking application...

Welcome Cape read post 562 on page 17 about Polar Moment. In my opinion, making a race car back into a go kart is stupid. This is what not properly using the Suspension makes the car as well as Bump Stops...why have springs?? Many post here on this as well. That has to be one tight paperclip...

many pulleys at various angles multiply the initial power of the winch

just saw this post, Good job Jack, as usual!

Excellent work! good job!!

C10 ,where is the 3rd link or top link located (attachment point to the chassis, not the rear end.) on the rear end? Mark the center lines of both rear tires. Now tell me distance the 3rd link is from each center line.
