SUNNEN POWER HONE EXTENSIONS
Because Sunnen’s hold downs are limited in their length, we made extensions to hold down various components. I use 3⁄4 -10 all-thread for the extensions and I can mount various work pieces with existing Sunnen threaded hole downs. This has been very helpful with Subaru blocks. We torque the two halves together and can now hold the assembled case in the hone.
