Overall this is a not a terrible kit. However, although there has been some care taken in the creation of the directions, they are not going to allow the average user to be 100 percent successful. And there are some issues with parts. There is a big sheet of directions meant to look somewhat like "blueprints" and it's a good start. They are clear about how to assemble the smaller sub-assemblies needed before putting those together to make the final product- and the drawings are pretty clear. However, when you get to the end and are trying to assemble the whole thing you realize that small errors made along the way make the final product "iffy". The manufacturer needs another round of real-world testing and editing of the directions. That being said, here's my advice for success. (I say this as a carpenter AND architect)

Use your own wood glue, like a good yellow carpenters glue.
You will need some spring clamps. Jorgensen "Pony" clamps, with the orange rubbery tips, are perfect. (they are like giant clothespins). A couple "small" and a couple of "medium" one will be fine. Check your local hardware store if you don't have these. You really cannot adequately glue up the "sticks" without clamps. We assembled two or three "stick" assemblies with glue and clamps, and left them to dry overnight. If you had a lot more clamps you could do more work in each session. As it was, it took us about 6 sessions. They don't say anything about clamping of course, but there's no way to ensure that the pieces remain tight and aligned while the glue sets up if you do not have clamps.

In Step 6, make user that the "upright supports" are perpendicular to the base. Use a square if necessary. Make sure that the holes at the top of the "upright supports" are level with each other!

Bought this and catapult for my class. The glue that they use is awesome. It sets in minutes..and I mean minutes. I had a 12 year old making it and a 10 yr old and they made it in about 2-3 hours. They did make some mistakes so I think a competent adult should be present . :). It works pretty awesome. Its not cheap either. We were shooting marshmallows and marbles and it threw them approximately 6 feet. We've used it for 9 weeks and it hasn't busted. the rubber bands on this one has lost some of its power now.

I often buy gifts that require a lot of parent/kid interaction, and this has been one of my six-year-old son's favorites. It took us a few days of glueing and some patience on his part, but once it was constructed, it was great. I bought a package of ping pong balls and a package of little nerf bullet-y balls and he has been bombarding everyone and everything in the house, and having a BLAST! I'm sure eventually it will pop apart from overuse, but till then...INCOMING!!

My family built this and the Trebuchet kit together. We found the Catapult fairly easy to assemble, but here's a few issues:

1. the base, when assembled, needs a stabilizing force when firing.

2. The glue-drying time is a bit of trouble. If you build it today, you can fire it tomorrow--supposed to take 12 hours. It's not bad, but just the reality.

Oh--and watch out for your pre-teen daughter aiming the catapult at her father. She can be dangerous!

It was good family fun to build this and try it out.

My nine-year-old daughter just loves this catapult. She's enjoyed making hypotheses about how far different objects will travel, aiming it at the target provided, & knocking down towers made out of Jenga blocks. The kit comes with a "blueprint" for assembly instructions, which she thought was cool, & I think constructing the catapult was almost as much fun for her as playing with it.

It was easy for the two of us to assemble the catapult; it took us around an hour, not including time for the glue to set. A couple of notes about assembly - I'd recommend using a hot glue gun rather than the wood glue provided, as it seemed to hold better. Also, the instructions show a "flight deck" made from one plain block, but the photo on the front of the box shows 4 plain blocks, which was what we ended up using.

It won't last forever, but it's a fun way to learn a bit about physics. We'll be buying the trebuchet kit soon.

It's a powerful catapult (the rubber bands are up to the job), but the catapult is, literally, pieces of wood glued together. I used the hot-glue gun rather than the wood glue that came with the kit (a suggested alternative in the instructions). It was FUN FUN FUN to put together, and LOOKS FANTASTIC, but it's fragile, and tips back when you load and set it. With every use, I was more worried about joints failing than where my projectile landed. These drawbacks make me want to just keep it on the shelf, which is a shame.

I bought this for a 6 year old for his Birthday. This was more of a purchase for an older child. I ended up putting the whole thing together. You have to get the measurements precise when setting up the wood or it won't work. There is no way a child, even age 7, could have done this alone. I was challenged by it a little.

I bought this to assemble with my boys (5 and 7). The instructions are very pretty (fake blueprint style) and they include a paper ruler to cut out with scissors to aid you in constructing the catapult. On the opposite side of the instructions you will find a large paper target which my kids enjoyed. I had fun building the catapult, but, there are a few issues with construction / instructions:

- There are some steps where the measurements were understated. For example, you are gluing 3 pieces of wood together and it will only tell you the total length (12") of all 3 pieces and leave it up to you to determine how much piece A should overlap with B and C. If you mess it up, your Catapult will be slightly lopsided. Be a little more careful with your measurements than you are instructed to.

- I used the included glue and it is totally not enough to complete the project unless you go very light on the glue (which is a bad idea if you want your catapult to stand up to the inevitable abuse it will face at the hands of your children). It is a good idea to have some additional wood glue on hand.

- The biggest problem, in my opinion, are the wooden dowels that are supposed to be held in place with the included rubber washers. The rubber washers don't do a darn thing to hold them in place. Seriously. They just fall off immediately. I am going to figure out a solution (I might swap the dowels out with bolts of the same size) but be warned: the rubber washers are useless! It is puzzling to me in a kit of otherwise high quality that they would have such an obvious oversight.

If you are adventurous and willing to make a few modifications, this is a fun catapult to get you going! If the idea of coming up with a solution or two that is not in the instructions doesn't appeal to you, you might want to pass.
