Anyone interested in a 1995 HAAS VF1 CNC Vertical Milling Center? I have used this mill to make many parts. However, now I have too many machines and this needs to go. I thought about putting it back in the garage, my wife just smiled and said "no". If any of you guys are interested in owning...

After building "Spikey" (my 5") L3 project I found that flying that beast on a regular basis isn't very feasible. I scaled down the design to a 54mm motor mount and have started building a 3" version of my original design. This rocket will be far less complex and much easier to prep and fly. The...

Well, my collection of rocket "stuff" has out grown the bed of my pickup truck. In an attempt to gain more storage space, a nifty mission control area and a place for the wife and kids to get out of the Texas heat, I have opted to build out a rocket trailer. I am starting with a Wells Cargo 7' x...

If you have seen my L3 build you will see that I have way too many switches on my AV bay. So I decided to build a circuit to make those go away. The RC folks have some solid state switches operated by a little button or two, but after watching a fellow rocketeer nearly loose a rocket due to one...

So, I have decided to build a pad controller to go along with Spikey, my L3 build, and a friends new launch tower. Several folks in our local club are diving in to larger projects and attending out of town launches so I figured a super cool launch controller is in order for our quickly...

I have searched and searched this forum for information about thermal expansion, primary in motor mount tubes. From what I have found filament wound fiberglass tube expands 18x10^-6 mm/mm/C, which at ~260C is enough to rip centering rings loose from the interior surface of a body tube or...

I have searched the forum up and down looking for references to camera hatches and haven't found anything. If anyone knows of some good threads that include such details please point me in the correct direction. I am looking for details about how others have cut hatch openings in the body tube...

I scaled up my shear pin reinforcement inserts to replace the plastic pins used to hold sections in place during flight. Much more solid and way easier to take disassemble.

Check out these shear pin inserts. I wasn't comfortable with the friction fit on a paper tube 4", so I crafted a washer insert and a threaded insert for 2-56 shear pins. What do you think? I am open to improvement ideas if anyone has some.

Waffling between scratch building or just modifying a kit for my level 3 certification vehicle. I am looking for reviews on high quality kits, designs, etc. Let me know your thoughts?

It seems to me that the basic charge cup has not been very well refined. I am designing a new style of charge cup (ejection gas generator) and would like to hear some others thoughts. If you have any ideal requirements you would like to share please do. Keep in mind that I am purely focused on...

Considering the purchase of a Madcow fiberglass Frenzy. I have seen a few Frenzy builds on the forum but not an FG model. Let me know your thoughts, good or bad?
