I'm building from component kits.  Feel like I'm on the "home 

stretch" now with the Fuselage kit sitting in my garage... 



Zentith has been 100% accurate so far in packing what they say the 

pack, as there is a shipping list that is included with the 

individual parts checked off, which I double check.



But in this case I don't think they intended to include the 

particular nuts, since they don't appear on the pick list.  They're 

just simple "jam nuts", so I think I'll "home depot" them and press on.



Thanks,



Patrick

Hi Patrick,



I'm afraid I have some bad news for you.  While ZAC does a fine job 

of producing its kits, they are not indeed complete enough to end up 

with a flying airplane when you finish using up the parts.



One of the new skills I have learned building my XL is how to find 

and order proper aircraft grade materials and hardware.  Perhaps this 

is a good time for you to start doing this as well.



A good place to start looking is Aircraft Spruce which can be found 

on the web at http://www.aircraftspruce.com/  The jam nuts you want 

can be found under "hardware AN316".  You will probably find they are 

less expensive for mil. spec. parts than your local hardware store is 

for junk steel parts.  Alas, you will have to pay for shipping and 

the art of selecting a shipping method for any given order is part of 

the learning curve.



I can't tell you exactly what needs you will have as you get closer 

to completion of your plane.  I can tell you what sort of things I 

have run into as I finish the fuselage of mine.



My most recent tasks have involved connecting the brake cylinders 

(from the kit) to the wheel calipers (also from the kit).  To do this 

I designed a new fairing and nylon support to pass the brake line 

(which I also procured myself - I didn't like the quality of plastic 

used in the kit part supplied) through the cabin floor.  This 

required finding bolts (AN3-4A) and nuts along with clamps (AN742-D4) 

to hold the line in place against the skin and grommets (AN931-4-7) 

to support the brake line as it passes through newly designed 

fairings for the rear of the main gear spring.



I have also been working on a design for the place where the nose 

steering tie rods pass through the firewall.  The drawings from ZAC 

leave this as an open wound in the firewall.  I ordered some 4130 

tubing from Aircraft Spruce (AKA "AS") that just fits over the 

threaded rod supplied in the kit and am working on welding a hook for 

a spring to hold my new flat 4130 piece in place on the front of the firewall.



I am currently on a side track learning how to TIG weld the parts I 

want for the firewall.  This is probably excessive since I already 

know how to weld with oxy/acetylene, but I wasn't happy with the work 

quality on such small parts.  Again, this is all about learning new 

skills so I am happy with the diversion.



The point I am trying to make is you will probably need to do many 

such things as you near completion of your plane.  You certainly will 

need to deal with things like engine, instruments, and perhaps some 

arrangements to allow your annual inspections to go smoothly.  If you 

follow the drawings you will need to stand on your head with your 

feet bumping into the canopy to look at the rudder pedals and brake 

cylinders on the cabin floor



You may find all of this a fun challenge.  If you feel stuck at any 

point you can always post a question on this list and you will surely 

get swift and useful answers.



Good luck,



Paul

Gents, the home depot aviation dept is useful for such things as wood for forms and small non critical things, but when it comes to nuts and bolts PLEASE PLEASE only install AN hardware. The AN hardware is a superior manufacturing process with far stricter guide lines. Scrimp on lexan and paint but not on the things that hold your plane together, remember you would shutter at the thoughts of actually using POP rivets to hold your plane together opposed to Avex blind rivets. You should also feel the same shutter for using low grade nuts and bolts.

Here is one source for parts.  They have tabs for Tech Info, indicated with a little wrench, which gives you a lot of info about the items.  I am not building yet, so I don't know about their service, but they are very active on VAF.
