Shucks you guys get to have all the fun, the last two days it's been a Indian summer here, something unusual about that this time of year. I'm working on getting two planes ready to loosen up the thumbs if it keeps this up.
I hope this storm of yours isn't as bad as they are making it sound like. Hunker down and coffee up some airplanes, good luck.

Over on this side of the mountains, we have had a couple of weeks of dense fog. Now, today it has cleared up and we were 64 degrees this afternoon. I guess that we have to put our foggles and sweaters away and take out the spring wear.
Stay warm,
Dave

The snow continues to fall and the totals are rising...some areas of the country the blizzard has been a bust, but here it has lived up to its expectations!

I thought I would tackle the firewall, so I first laminated a 1/4" piece of birch ply to a 1/8" piece using epoxy, this should give me the thickness strength that I'm looking for. The firewall will actually be a three piece lamination with the outer layer being a full sheet of aluminum. The total thickness of the three pieces will be .424". The aluminum was added for the following reasons:
1. eliminated the need of washers under the engine standoffs
2. no fuel proofing needed
3. give me some bling!
Taking careful measurements off the plans I transferred the centerlines to the firewall blank. Since the top of the firewall is in contact with the fiberglass cowl, it must follow the contour of it. I found that the top angle of the firewall was five degrees, so I replicated that angle on the firewall blank.
I decided that this plane will be powered with a DA-50RA, not having purchased the engine yet, I searched on the internet for a DA-50 drilling pattern schedule. Having found what I needed, I taped the pattern atop the firewall blank being sure that the vertical and horizontal centerlines were spot on. I also made sure that the dimesions indicated on the pattern were accurate, I verified that they were using a sliding caliper. Not having the engine on hand one has to be positive that all the dimensions are as accurate as can be...
The drilling took place at my drill press as that is the only way to get true straight holes. The size of the holes were left undersize as I don't know what bolts that I will be using. Final sizing the holes will be done by hand once the firewall is epoxied in place.
As a side note, I offer this tip, one that I have given in all of my other threads. One of my steel rulers is faced with a piece of 220 grit sandpaper, this ensures that my ruler stays in place and will prevent it from sliding on what ever I happen to be measuring...

Looks as though I'll have another day to work on the Bravo tomorrow, school is cancelled!
Thought I would finish up the evening showing you the completed firewall, which has now been clad in aluminum. Just need to epoxy it into position...

Looking great VJ,
How about I send you a list of planes I do not want you to build so you don't set the bar to high for me or make me throw mine out? To start with a WACO and a Stinson Reliant.
Enjoy the free day tomorrow.

Thank you Glenn and Anthony! Glenn, condo living has certainly made my life easier in the respect that I can enjoy the snow now and take solace that I don't have to go out and shovel it any more!
Anthony if you ever throw any of your planes out I'll be the first of many that would be in line at your garbage can to retrieve them, LOL.

Wanted you guys to know that I have decided to purchase my own condo, which I am very excited about. The basement is large and unfinished, can you tell where this story is going? I will finally have a workshop that won't be the size of an overgrown closet, that is ... when I build it. I hope to be colsing on this property within the next month. That means again, a lot of packing and unpacking. My dear Bravo will have to take a back seat until I can restore order in my life, so things may slow down a bit, but I can assure you that it will never stop...just wanted you to know.

Although we may find it hard to realize, there are things more important than our hobby.
Get your moving done. We'll be here when the build resumes.
As always, I volunteer to move and store your models..

Thanks for the offer Tom and the chuckle, I needed that! 
Kevin, the down side to this is I am afraid that a larger workshop....means larger planes!

"A condo", means he is going to go live with a bunch of old folks, I suppose that isn't all bad, they have some great stories to tell, drink coffee and don't shovel snow. Vincent you'll fit right in and as long as you have a shop you should be a happy camper. He he

Congratulations on the condo! Great news, however i would advise discretion in committing to bigger airplanes. You still have to be able to get them out of the basement (shades of Agent Gibb's boat building on NCIS) and you still have to be able to haul them back and forth to the filed.

You guys are too funny! I was very picky when it came to the basement, it has a bulkhead so getting planes in and out of the workshop is a breeze. I plan on storing my large planes in the garage so they can be transported to the field, which by the way is only a couple of miles from my new digs...
