Aft Gear Attach Bulkhead

I completed the aft gear attach bulkhead. Here it is ready for glassing:

And glassed:

I'll try and do better about keeping my blog updated in a more timely fashion. On the plus side, I've started a new 7 days on - 7 days off shift which should allow me more time to work on the aircraft. On the minus side, I've started studying for my dispatcher license and that will take up a good deal of my time in the near future. Minus being that I'll have less time to work on the aircraft, getting my dispatch license is definitely a good thing overall. Just have F-22 and the firewall left in chapter 4. Hope to complete that next off week (I start my on week tonight) and get things prepped for Ch.5.

Forward Gear Attach Bulkhead & F-28

I've completed the forward gear attach bulkhead and F-28. I traced the outlines for the G.A.B. hardpoints onto the solid fiberglass from the plans and cut them out using the router attachment a fiberglass cutting bit for the dremel. It wasn't easy and I ended up cutting close to the trace lines and then sanding w/ 36 grit sandpaper to fit. Worked well, just took a while.

Here are F-28 and the upper portion of the forward GAB and F-28 ready for glassing:

The upper and lower sections will be joined later. Upper portion of the forward GAB completed:

The lower section of the forward GAB ready for glassing:

And completed:

F-28 completed:

IP Complete

I realize that I haven't posted in a while, but I have been working on the aircraft. The IP is complete now. I finished glassing and then added the stiffeners. Here you can see them cut and laid out. I might add that I shortened the vertical stiffeners when I realized that they were too long:

I used 2x4's to hold the pieces in place while 5-min epoxying them into place:

All stiffeners in place w/ micro along the edges:

For the electrical conduits I would glass first the single ply on the upper surface, allow it to cure, and then do the 2 plies for the conduit itself as shown below:

Finally, the IP completed:

Instrument Panel

Glassed the front sided of the IP this morning. 2 plies bid overall and 1 ply uni above the thigh cutouts.
Here it is ready for glassing:

Gear Attach Bulkhead Hardpoints

Last week I laid up the 1/4" solid fiberglass hardpoint section to cut cut out the gear attach bulkhead hardpionts.

Here's the 22 plies of bid laid out and ready to epoxy:

And ready to cut the hardpoints out of:

Aft & Forward Landing Gear Attach Bulkheads

I ended up having some extra time this evening and was able to cut out the forward and aft landing gear attach bulkheads. The .25" foam used for these two bulkheads was a lot easier to work with then the .2" used on F-22, F-28 and the IP. I was able to cut everything with a razor and then just do some light sanding.

Everything laid out and ready for cutting:


And everything cut out:

F-22

I finished cutting and shaping F-22 and the F-22 doubler on Tuesday and Wednesday night. Here they are traced out and ready to cut:


Cut and ready to by 5-min epoxied together:


5-min epoxied and weighted down:


And finally, all put together and ready for glassing:

Well, its back to work tonight and I'll be working several overtime days next week, so I don't expect to get too much done. Still need to finish shaping F-28 and then it's on to the landing gear attach bulkheads and the firewall/temporary firewall.
