If you're just starting to learn about the Spank-O-Matic line of machines, please start with the SOM II. The pictures and text on this page focus on the uniqueness of the SOM II XP, and mostly ignore the features shared with the standard SOM II.
XP... extra power! If you need the most powerful machine spanking available at your fingertips, this is the machine for you. The SOM II XP uses twin valves and cylinders, developing twice the power of the original SOM II, all controlled withe the same computerized flexibility and accuracy. This only difference in the XP is the double-barrelled head unit. All other components are identical to the standard SOM II.
The mechanics of pneumatic power mean the parallel cylinders can put more than 500 pounds of force behind each stroke. Additional leverage against the spanking arm take advantage of this massive power to create higher accelleration and a significant upgrade in spanking force vs. the already-powerful SOM II (estimated at a 40% increase, although mechanical assessment of actual striking power is in the works). This is a machine to respect! As always, use the higher incoming pressures and power settings with due care! Higher levels of play within the range of the SOM II XP are not recommended with non-Lexan end effectors such as the cane set or oak paddle.
Please note that I do NOT recommend the SOM II XP to the average spanking machine user, only to those REQUIRING extreme striking levels with heavier implements that can put it to use. This extra power comes with a cost. The XP model uses roughly twice the air volume of the standard SOM II, at any given power level. I generally recommend a compressor rated for 2.0 CFM or more at 90 psi. The mild air exhaust sounds are likewise doubled. The SOM II was designed to fully meet the needs of the vast majority of machine spanking afficianados, and will strike as hard or slightly harder with light weight implements.
I've added an option to purchase the SOM II XP with the LT stand instead of the standard SOM II stand. This provides a cost saving option (I don't have to do nearly as much work on the LT stand!), and is just as rigid and adjustable. The disadvantage of the LT stand -- its light weight -- is evn more important with the XP head, however. The XP head weighs more, has more moving mass, and operates with twice the force of the standard SOM II head unit. These factors combine to generate additional movement potential, to which the lighter LT stand provides less resistance. You WILL need to weigh or secure the LT stand in place when used with the XP head unit. Please remember this caution when considering the LT stand option with this machine.
Again, please see the SOM II pages for a more comprehensive description of the SOM II features, technology, and advantages.
