Ok I want to set the record straight…. I have read on some boards that they say that placing a cant pin under one side of your wood body to drill canted holes will works. NO IT DOESN’T. Will it drill a canted hole? YES… Will the canted hole on the rear of one side of the body be the same as on the other side? ABSOLUTELY NOT. For that to work it would be like winning the lottery.
In order to make the holes identical from side to side you would have to place the cant pin in the EXACT same position on each side. Also the wood body would have to be PERFECTLY square…. If your wood body is not square or your pin isn’t in the exact same position then your holes will NOT be drilled at the same angle and your car will have an alignment problem.
The Silver Bullet works because you are not relying on the wood block to be square at all. You are relying on the precision machining of the Silver Bullet. The slot to hold the pin is also machined in the same exact location from side to side…. So when you flip the Silver Bullet to drill the opposite side you get EXACT alignment.
Also…. Your drill press table does NOT have to be perfectly perpendicular to the spindle to use the Silver Bullet nor does your spindle have to have zero run-out. With a table that is a little out of perpendicular you will have a car that has an unnoticeable dog track, but the rear canted holes will be aligned. With a spindle that has some run-out you will have a larger axle hole, but it will still be centered on the right spot. Just make sure your drill press table is flat, that your Silver Bullet doesn’t move and your drill bit doesn’t wander.
Next…. Precision angle blocks… Can you drill good rear axle holes with this tool? This is better than the previous method, but you are now relying on the wood block to be perfectly square. Have you found a wood block that is perfectly square?
I am guessing that anyone using these methods with any speed is still bending a rear axle to tune it into alignment and then they go out and buy a lottery ticket.
