Kevin=2C
I normally do the first layup with a single dry ply and dart the corners as
in any proper layup technique. I prefer not to see my clients make tapes
as it tends to make for more voids and sticky messes when it goes a bit wro
ng. The uni is applied to the inside of the bay after the bid. During the
layup of the dry glass procedure=2C the sticky initial layer and flox make
s placement of the white glass in the dark hole and cutting and darting eas
ier for me. Good sharp shears are essential. In the dry glass layup=2C yo
u will use more epoxy as gravity works 24/7 so simply peel ply and mop up t
he excess when done and let it cure. Use just a bit of denatured alcohol i
f the puddle is getting sticky. Remember to leave a tab to pull the peel p
ly by.
Go slow=2C take your time on getting your ply pieces fit well. My clients
have me do the cuts as I am faster=2C but don't trust the manual cutouts=2C
make a template from cardboard and fit it in place. Be sure to leave work
ing room around the mod 52 tube and socket. You will find that the dry gla
ss layups can go fairly fast=2C but with the top on it is a real back break
er. Get yourself some good cool running LED lights for good visibility (in
candescent bulbs make it a very hot job in Florida and the glue kicks very
fast) . A small 4 by 4 inch mirror is essential to check for voids and dry
bid. In places it is necessary to cut the handle of the brush down and ro
und it off so it doesn't snag anything to get in those corners well.
It is nice to have one person glassing one side=2C and I on the other=2C wi
th a helper mixing 100gram cups of epoxy as we go. I've done the project i
n 4 days but prefer 7.
My back can't take it so I do the inner and outer initial reinforcements on
day 1.
Day 2 I do the final line up of the tubes and gear and check everything abs
olutely right and the aircraft jigged dead solid. Redux in the tubes.
Day 3 I install the first rib and allow to firm up then lay glass over it a
nd allow to cure. (With the top on it may be best to set the rib=2C peel p
ly and allow to cure. Glass the next day.
Day 4 is Rib 2 unless I work a long Day 3 and install rib two over tacky gl
ass and bond in both in one day. You gotta be quick and good for that and
have a kit with the top off.
Day 5 are Rib 3 and 4
Day 6 grind the tops and clean up=2C then apply uni. You can pop the gear
and finish up or...
Day 7 Pop out the gear=2C finish the outside layups=2C and reinstall the ge
ar=2C pull the fuselage from the jig and put on the brakes and wheels...
Working alone=2C make it a half a day for 14 days and save your back and ma
ke it a more enjoyable easily paced project...
Bob Borger posted how I do my jig setup in my shop=2C and if memory serves
=2C it took a full two weeks to pull the gear=2C clean up and put in the tr
i-gear=2C we mounted hand brake cylinders in the tunnel per my standard and
closed up the belly with new firewall with 4 of us working.

> I know this has been discussed before but I am just preparing the baggage
bay for the landing gear reinforcement layups and have a few questions for
those that have gone before me and successfully completed this mega task.
>
> The manual states =93 layup 2 plies of bid over the entire area of
the baggage bay up to the level of the top of the centre tunnel.
>
> a) Is this best done in one piece of bid? The manual does not state any
preference. What have others done?
>
> b) If done in one piece of bid=2C is it okay to cut the corner folds and
overlap? This would certainly make for a simpler and neater installation a
nd would also increase the number of layers in the corners. Surely a good
thing?
>
> I intend to layup the bid on plastic=2C my normal method for easier handl
ing=2C before attempting to introduce to the baggage bay.
>
> Next=2C the manual states - add 2 plies of uni=2C to the same height=2C o
nto the baggage bay rear bulkhead from the sidewall to the central tunnel
=2C with the fibres running spanwise.
>
> c) I am assuming this is just on the inner aft side of the baggage bay bo
x?
> Also=2C there is no mention of any overlap onto the floor=2C sides or cen
tre tunnel=2C so just into the corners then?
>
> Interested to hear what others have done for this part of the build and w
hat is considered best practice for this layup.

> The fuselage top is still off so slightly easier but the back support bel
t and pain relief cream are standing by!
