Thanks for the kind words Guys. Where there is a will, there is a way.
Fed Ex just delivered the PVA,Pigment, and 50 yards of carbon tow. Fiberglass was ordered today as well, got 50 yards of that also. I think I'll have enough materials, lol. |

Thanks guys, Today I went shopping for the local supplies needed for the glassing. I picked up the resin, prepsol, FG matt, spray 77, and filler. The FG cloth should be here early next week. I think I have everything now. Pete,Karl, am I missing anything??
I also got a E-mail from Dave Binkley with a dimensioned drawing of the full size Monocoupe cowl and blisters. I will be going over the drawing today and seeing how close my plug is. Thanks Dave!! I am hoping to have the plug for the cowl done monday. |

After making some measurements from the full size mono cowl, The AMR Cowl and My plug I have a plan of action. Resin is currenly setting up on the AMR cowl blisters as they will be modified and used in the making of the plug/mold. I lucked out and the template I made for the round part of the plug is right on size for the fuse and scale . I need to go out and get a different putty to use on the plug for sealing the foam before I can finish it up. Things are going in the right direction it seems. I amkinda liking this fiberglassing stuff actually, lol.

Success!
Awsome,
So the resin set up on the AMR cowl blisters and it poped off perfectly! No resin stayed on teh cowl and I now have 3 blisters pulled off of it. One of em did get an air pocket that I didn't see but other than that they are smooth and strong! next I will modify them as needed so I can make 14 good ones for the plug. I could get to liking this Fg stuff. |

Hello karl and thanks for the comment
Rob Very good, your doing well. So whats the idea with the blisters are you going to press them onto the foam plug and then make a cast of that as the mold? I'm just thinking about the transition of the blister to cowl joint will need feathering with filler to make it blend in so as not to look like the blisters where added after. Also a reminder if you are making the cowl in two pieces but only casting from half of the plug to save time. You will need to add a lip so the second half can be joined. Prolly be a good idea to have a split cowl instead of a single unit for engine access. I like the part where you say your enjoying glass work. I'm assuming you haven't reached the itchy scratch stage yet. That'll come when you start cutting and sanding. Oh the fun you're going to have. Rubber gloves help to stop it and so does a barrier cream like Nivea or similar. |

It is very rewarding when you pull a good part out of a mold. Ahhh... the stupid things in life. |

Pete, You are correct, the blisters will be grafted onto the round plug, feathered in and sealed up. Then the mold halfs will be made from that. I am heading out soon to get the drywall compound to finish up the blister mold and start pulling the final blisters. hopefully by the end of the night i'll have 14 blisters to graft onto the plug.
LOL, I have not got to the itchy part yet but I have gloves ready! |

I have a refrigerator pump for the time being. it works ok, but is slow on the pulldown. It will work fine for this stuff. Thanks for the offer. Someday i'll get an actual pump to finish off the system

I had a 6" diameter x 10" long 'reservoir tank' made of simple PVC sewer pipe and caps, with an inlet and three outlets (two for bags, one for the vacuum gauge). Using the refrigerator pump alone took nearly an hour (it seemed) to pull a vacuum on the tanks and the bags, but the shopvac pulled it right down in a few seconds. I was bagging FG/carbon over blue foam for sailplane wings, so I was running relatively high vacuum. I assume you will go even higher on the vacuum. The pro vacuums (Gast, etc) are very nice to have, but starting with the shopvac then switching to the refrigerator worked well enough for me at the time. If I used the system more than a few times a year I would consider buying a good pump system. |

I have a large reservoir as well on mine. I typically don't have any issues unless I am bagging a huge wing panel or something. The shop vac method works very well also.
I ordered the aluminum tube for the LG today as well. About that pesky gear.... The final method and materials have been chosen. I will be making my own tubes out of FG and CF tow for the outer structure. The bends at the top will be aluminum tubing for strength. I will be filling the structure with foam or balsa and then glass the entire gear. this should produce a light and strong gear that will look scale. |

Well, it is now the end of a very stressfull day for me. I found out I got scammed out of an electric kit on another site by some dude named Arcadio Mendez. 2 others have also got scammed, low life pr!ck. So I went home and decided to pull a part from my newly made mold for the blisters. well the part decided it liked my mold sooo much it was taking part of it with it. 3 minutes of cussing later I figured that I pulled the part to early, lesson learned. I cleaned the mold, put some more putty on it and it is now curing. Tomorrow I'll sand, paint, PVA, and try again.
I decided I couldn't do much more damage so I fired up the Redneck Mfg. Lathe and sanded down the putty on it. I then shot it with latex paint to make everything stand out and applied putty for the second time where needed. this worked pretty good actually. below are some pics. I also got the Flycam One in the mail today. turns out The memory card just needed re-formatted and ta-da a working cam. Best $5 I ever spent |
