David- Here's a quick tracing of a leg and the top plate. One dimension is provided on the top plate side, and I have also provided a "1 inch scale" on the side of the page. The 'black dots' are the drilled holes in the top plate. This was done super-quick, as I'm at home recovering from a bad upper respiratory infection, but hopefully will be enough data to let you do an accurate comparison between the two. My impression is the LIA-100 is a bit bigger than the 77 than the figure you posted, but hopefully with this data, we'll know pretty much for sure. Earl

Thanks for the well-wishes. I'm sure my asthma is not helping, though I'm generally fairly symptom free with my asthma. I guess this virus has aggravated it though. Yes, this is the LIA-100 tracing. I traced it all on one single piece of 8.5 x 11 paper, hence the leg done in two pieces to fit on the one page. Also, scanned at 72dpi, so the resolution is not very high, but should be enough graphic info to derive the needed dimensions. Earl

That was a clone Mach-1 Dart and Booster I built to use 21mm FSI stuff. I built a few of those and I think those were the last two that I did build. I belive it was an E5-6 that did it in with a D18-0 Booster. It cruise missiled across a four lane highway into an asphalt parking lot on the other side of the highway a pretty good distance away. Results weren't pretty but it was pretty cool to watch! .

I still have my LP-2 3/16" and LP-2B 1/4" FSI metal pads. They are in storage at my friends house along with my EC102 launch controller. That controller was a trip. With an FSI electric match as soon as you plugged the cable into the hand held part of the controller the electric match would ignite immediately without pushing the button! I seem to remember a warning in the electric match kit about that ... I will see if I can get that box pulled down from the attic this weekend and see what't in it. It's been in storage for 7 - 8 years since my last move but I do remember keeping all my blast deflectors in that box. I also liked the fact that with the legs folded in that both my pads could also be transported inside the box, the smaller metal pad settled inside the legs of the larger pad. .

Ok here is the updated comparison. They didn't consistently scale the legs with the base plate, so the LIA-100 does stand taller than the LIA-77. The deflector appears it is scaled along the lines of the base plate (about 1.12X), but that is just a SWAG on my part (based on the catalog images). edit: added the catalog bit |

David-
Ahhh....pretty neat! Thanks for the comparison graphics. That looks about right from one photo in the Centuri catalog that has the Saturn V and Saturn 1b in one photo (I think the photo was in the '69 through '71 catalogs). I have assembled one of my 77s, but have never fully assembled the 100.....the hardware is still sealed in bags. Either one is a pretty stable launcher. Earl

I used my 77 a bunch...I think one of the legs split through the bolt holes along the plies, after many assembly/disassembly cycles. It is an elegant looking thing, isn't it? |

Hi Earl, Thanks for posting your line drawing of the Centuri LIA-100 leg and base. I thought I had a scan saved of the original Centuri LIA-100 instruction sheet, but I can't seem to find it if I actually did scan it. So, I'm going to have to re-scan it again and upload it. Since my LIA-100 is painted: Legs flourescent Red and the Base flat black, I'm trying to remember what the actual legs were. I think the legs were Pine or Poplar. I know the base was 1/4" Masonite Hard Board. Regards, Larry B |

Larry- Thanks for the post.....I actually have a complete LIA-100 and the instructions are scanned and posted in my first message of this thread. In that first message, I was asking if anyone had the larger blast deflector that came with that launcher, as my LIA-100 came with the smaller deflector used on the LIA-77. I think Centuri may have used the same deflector for both launchers in their latter years, but I would really like to find an original larger deflector for my LIA-100 or someone who has one who can provide photos and dimensions of one. Does your LIA-100 have the larger deflector by chance? Would be great if you can post photos/measurements if you do. Thanks, Earl
