The apparatus behind the jack pads is a lathe headstock spindle support, this is mounted to a lathe spindle, opposite the lathe chuck. An example of use would be re-chambering a rifle barrel. The barrel is passed thru the lathe spindle and clamped in the chuck and supported on the muzzle end by this device. The purpose is to prevent the barrel from whipping when rotating in the lathe and improve the rife accuracy.

Hi Mark, in response to your questions:
The bracket mount portion of the Sky Designs jack point is 1/8" shorter than the "standard" bracket mounts supplied in the kit. If you're retrofitting our jack points to an already finished and flying wheel fairing installation, it will likely be necessary to use a shim under your inboard wheel fairing bracket. If you have yet to fit and install your wheel fairings, then the height difference will be lost in the noise of all the other variables associated with fitting and installing wheel know how that is ;-)

You'll need to use your uni-bit to drill a 7/8 diameter hole in the inboard wheel fairing brackets to allow the jack-point boss the protrude through. The threads are 1/2-13 and we supply a 2 inch long "Grade 8" 1/2 inch bolt and nut in the package. The reason for this is that the bolt must be "grade 8" (130 ksi min yield strength) and no longer than 2 inches in order to support the load. The design load is 700 lb.

As for accessing the head of the bolt from the front as opposed to the side, that will depend on the exact dimensions (height & width) of your jack. Some floor jacks allow you to get in nice and close whereas others aren't so compact. If your jack allows you to get within 2 inches, then you're good to go.

I hope this helps!
