You want the driving head to spread the impact over as much of the sheet (pile) head as possible. Will overall dimensions of the hammer allow driving singles without interference with adjacent sheets?

Presume that exposure is to sunlight if UV is causing the fading. What type of coating is your supplier using? If you have the ability to specify the coating it could solve the problem.

Don't forget to enter the driver variable into any on-track performance numbers. As Rod is well aware, the applicator of pedal to metal does make a difference. Even if the '68 Camaro did make 500 HP, just switching drivers could produce faster times.
Having played with a '69 Z/28 back when...
Take a look at D1.4 Section 4.2.6 and Figure 4.2 which call out a minimum distance from the point of tangency equal or greater than 2 bar diameters.

How long are the finished rods? If possible, it is recommended that threaded items have excess zinc spun off as they come out of the zinc kettle. Some galvanizers are equipped to do this.
Spinning helps to provide a more uniform accumulation of zinc in/on the threads enabling easier nut...
Tension of each spoke has to maintain roundness of the rim regardless where they are in relation to the direction of loading. The portion of the rim being compressed can reduce spoke tension. However, if the wheel is to have a chance of staying round and true, all spokes have to have been...
Tension of the spokes has to be right and depends on the type of wheel, rim, hub, size of rider, riding surface, etc. Commercially built wheels are built to the lowest common denominator, acceptance level, price point and are usually not tensioned to very high levels. Custom wheels are hand...
Typically, sealing of annular space around piping is based on requirements for preventing water penetration or fire resistance. For centering/support of pipe and filling the gap a link-seal is commonly inserted then caulked with a sealant. This type may also be fire rated. Fire resistant...

Practioner of a Black Art indeed. There have always been lots of parts selector/assemblers out there. Some working to very precise tolerances and clean to a fault. But, not many have been able to make every motor they touch the one to beat.
I thought that I was OK at tuning, but...
Precast piles have seen rebar dowels (pourable cement or epoxy) grouted into sleeves of material similar to metal flex conduit. The spiral convolutions of the flex and rebar deformation provide resistance to pull-out.

A flowable, cementitious fill material, whatever the acronym, would seem to be the quickest, easiest and cost effective as well. Something like what we refer to as 1 to 2 sack (90 to 180 lbs of cement per cubic yard) sand/cement slurry. If you are in a real hurry an accellerant could be added...
The 475 number is about what Traco was supposed to have been getting out of their Trans-Am 302 CSB according to what I remember. A well tuned in-the-car stock Z/28 would be around 375, sometimes a bit more. The Penske cars were another matter. A combination of motor, drivetrain, chassis...
