Ooops! I got that price way wrong

Earlier post I wrote that the Ford 9″ axle was $1100, well it turns out that was just for the lightweight centersection with positraction and the fabricated housing was another $850 or so. So, $1100 for the lightweight centersection, and $850 for the housing kit plus the floating caliper bracket kit for $400 and the 9″ from the catalog looks a lot like the price of the Quick Change from the catalog, particularly if I need to buy an $1100 centersection for each ratio I need instead of a $70 (Edit $39.99 or $49.99 depending on material) set of spur gears for the Quick Change. Time to change ratios is about the same for each one with the nod going to the Quick Change by a few minutes over the Ford 9″ because you have to drop the driveshaft and do a bunch more nuts when you change the centersection compared to removing the back cover and swapping spur gears.

One thing I need to look at is the cost of a set of Helical cut street spur gears instead of the normal straight cut spur gears used for racing. I know the straight cut gears are listed at under $70, but I can’t find a price on the helical cut gears that mesh like the gears on a standard transmission and are quiet to Very Quiet depending on the ratio of the gears. Some sets have a very quiet mesh-unmesh like the gears in a transmission, some are just Not As Noisy as straight cut spur gears of the same ratio, and some of the Very Quiet gears are not swappable top for bottom and have to be installed in a specific orientation. (Edit, I found the Helical Cut Gears for the Quick Change and they are $60/set, but the Very Quiet gears that have to be installed only one way are $130)

Something not hot rod building is the continued winter weather system settling its icy butt on our weather. As I compose this the temperature for Casa de El Poeta reported by Weather.com is +13°F drybulb and -4° index, both of which are way warmer than the +9°F drybulb and -14° index I saw right before bed. Also, we have snow and bright sun right now which is making the inside of the house very bright (and also very cold, as the heat pump doesn’t have much to work with in these temperatures). Now I’m going to retire to the living room which is much warmer than sitting next to the drafty window working at my desk.
