We got the stab re-installed and cables reattached tonight. We'll need to install some washers between the brackets and bearings, but I'm pretty sure I'll be able to get them in with my washer wrench. I hope so, anyway.
There were no washers there before. Don't know why, maybe they weren't needed.

Just completed my Stab SB and offer a few observations on the stab reinstall:
1. Van's suggestion to instant-glue the original configuration washers to the new brackets worked great -- be sure to abrade the gluing surfaces for max adhesion and use a touch of grease to help the brackets/washers slide onto the bearings. CNC accuracy and Van's engineering are amazing in that my original washer configuration perfectly fit the new brackets/bearings.
2. Find two friends to help you position the stab. Alternatively, you can build up a table or sawhorses to get the stab in position -- the stab reinstall can then be a one-man job.
3. Forceps or long-handled needle-nose pliers working from below can be used to initially position the bearing bolts. A set of extensions for your socket set is necessary to final install and torque the two bearing bolts.
4. See Scott Millhouse's earlier post (#110) regarding the reinstallation of the stab cables -- that worked fine for me. Thanks Scott for the tip.
5. There is the potential to scrape the forward portion of the stab against the aft sides of the tail cone when you initially remove and replace the stab. Tape some protective sheet plastic or heavy paper in these areas to prevent scratching.
I wasn't looking forward to the stab reinstall but it took less than 30 minutes and went according to plan -- Yeah!

One tip: We found that by putting the stabilator in place with the HS-1210 hinge stops contacting the F-1211C hinge bracket (upper or lower, whichever works for you), the bearing bracket holes were trivially easy to line up for the bolts to go in. It just puts the stabilator in the right position for everything to line up.

Has anyone done any detailed write-ups on their builder's blog on the Stabilator SB? Asking for a friend.

Hi Kevin, no detailed write up here, but I can tell you it took me about 12 hours, it involved more than I initially thought. Here is the completed image, this is the top view, the bottom is basically a mirror image of the gussets and the stabilator horn. Glad I did this before painting. You throw away the old hinge brackets assemblies.

My pleasure guys. Here is another one that may help. This is the bottom view. By the way, great to see your name Joe! It's been almost 2 years since your 'open house' at LVK, and your RV-12 was almost complete. I wondered what happened to you, hope all is well. Paul

Several comments were made concerning the difficulty of inserting the spacing washers during the stabilizer install.
Ref: SB-18-02-02
Step 4: Taking note of the washers used between the Hinge Brackets and pivot Bearings for reuse later, disconnect the Stabilator Assembly from the Tailcone Assembly as shown in KAI Page 10-05 and KAI Page 11-03.
Refer to the KAI references above, it will instruct you during the assembly process to bond the washers to the inside of the bracket assemblies. This will facilitate an easier stabilizer install. Then all you have to mess with is aligning each bracket assembly with its respective bearing then insert the hinge bolts.
I'll be installing the stab tomorrow.. Just hope I don't have to mess with the turnbuckles.
Regards,
