You’re lucky they weren’t loaded!!!!

Hi Ed

Your guns look great.

RE the bright blue skies; We had a run of crystal clear days with light winds. Cruising down to Stow Maries at 3500', I could see Colchester from 50 miles away but didnt seem to be getting any closer.

Re the Safety Locks; The safety lock mechanism was removed if the guns were fitted with the full cross bar padding. So I did the same.

That looks great Pete!

Help! I'm am completly dead in the water. I have een searching lumber yards all over the south and can not find anyone that still carries 1" plywood anymore. The best they can do is 3/4 or 18mm. Is it available in other parts of the country? or does anyone have a sugestion for an alternative. I thought about MPB but with the humidity here in the summer I'm afraid it will deform at a critical time. Any sugestions will be most appreciated.

Hi Jerry,

I promise you I am not being difficult, but do you mean 1" thick, or wide? Either way, what part of the triplane is this for?

Maybe for the jig table? 3/4 is fine.

After a little bit of back and forth communication with the FAA to answer various questions regarding W&B, instrumentation and potential ADs concerning my engine, we now have a visit scheduled for next Friday. There was an offer for this week, but I want the additional time to make sure everything is truly ready, and I've been busy with mortal affairs ("work").

Won't be much to report until all of this is in the past tense. I'll report back then.

Thanks,

Jim

Sorry, I wasn't very specific. I have decided that I should start my build with the spars and am refering to the spar jig. If 3/4" plywood is sufficient to make the jig then thats how I will go. I just don't want to have the spars fall less than true and square because the jig was built to weak. Thanks for the responces.

Thanks Jerry. I used a laser to true my table up, on both the table for horizontal flatness and along the sides to ensure trueness. I think I used 3/4" this material for the base. You can always beef it up on the backside too!

Did you only specify 1"? because 25mm is more common and is about the same. I would think 3/4" would be ok if well supported.
