I am launching in Argoina.
Sorry if you've posted this previously, but which KlOUDBUSTERS event do you plan to launch this project?
I am launching in Argoina.
Well boys I am one step closer. I order custom shock cords from Mark at LOC. I ordered 30 foot 1 inch tubular nylon, 3 foot 1 inch tubular nylon, 20 foot 1 inch tubular nylon, and 1 inch 5 foot tubular nylon.
The 30 foot will anchor to motor then attach to a quick link, the 3 foot will then attach to the quick link then attach to ebay. LOC Angle drogue chute attaches to this quick link. 20 foot will attach to other end of ebay then attach to a quick link. Then 5 foot will attach to quick link and anchor to nosecone. The main will attach to that quick link near nosecone.
This is the recovery system I will be using. I have not yet ordered, but will in a few weeks. I will be getting the "Size 10"

Nothing really new to report. Just waiting for the weather to warm up so I can do T2T with vacuum bagging. I thought of an idea. Kent burrnet said Aeropoxy must be used with ambiant air temperature at a minimum of 75 degrees f. My thought was to get at red heat lamp from lowes that is like 250w. Plug that in and point it in the direction of the work and let it heat up the room where I am working. Is that a good idea or not smart? I figured it must be on for a while, just enough to bring room temp to required amount and leave it on until the epoxy is cured. But IDK?
I think Kent is being a little too cautious. The can may say to use at 75 degrees and up but I've done several layups this winter all in the low to mid 60s with no adverse effects. The only noticeable difference is it takes a tad longer than 24 hours to fully cure. After 24 hours it's still pretty hard, but not rock hard. I would just move the project after doing the layup, and put it in a warmer spot like under heat lamps you mention to let it cure, if you want the normal 24 hour cure or quicker. I actually prefer to use Aeropoxy at slightly lower temps, as the working time seems to be extended a little longer than 1 hour (for the 3660 hardener).
This is the type of vacuum pump I am looking to get. Its the lowest price I have seen. https://www.ebay.com/itm/like/321312047858
Seems to be good. As long as all leaks have been sealed this pump should work.
This looks pretty similar to one at Harbor Freight.

I use the Harbor Freight one - because I have it - but there are likely better choices. One issue is that these HVAC pumps go to nearly a complete vacuum. With some epoxies, a somewhat lower vacuum is more desirable (although this doesn't seem to be an issue with Aeropoxy). The other issue is that you get oil in the exhaust. This can be minimized by having everything well sealed (the more air throughput, the more oil you get). Even though the oil can be minimized, I still attach a hose to the output and vent it outdoors.

Only if you like frequent returns to China Freight.
I also have a Robinair, I bought back in 2003 and still running!
I use mine for degassing as well.
You need to change the oil every so often.

i like these pumps, but I am worried about continuous operation. I dont want to burn the pump up, or can it run all the time? If it needs to be run for a long period of time should I look for a more expensive pump?
I have the $80 US General pump from Harbor Freight that Jim has...
I bought a digital thermometer last night at Lowes. I was concerned about the temp and humidity in my rocket room. For one if the temp is to low (lower) than 77 degrees Kent burnett said Aeropoxy wont setup right, must be over 77. After the themometer was up there for a few hours, around 9pm it said the temp there was 76 degrees with 37% humidity. So if I wait a few more weeks, lets say by the beginning of April my rocket room should be higher than 77 degrees. But hoping the humidity level is still low. I figured if I get the temperature i want, but the humidity is higher then I would like I thought about getting a dehumidifier. I dont want the epoxy to blush!
