Until STRAWBOT kits go into production mode, you'll be making the pieces with good ol' hand tools. I'll leave it up to you to decide what cutting method you use. I believe that scissors and and exacto-knife should be on hand.
Punches are what allow straws and foam to come together and make STRAWBOTS. In the following steps I'll highlight your basic tool options when it comes to punches.
Step 1: Round Hole Punches
If you're serious about building all of the current STRAWBOT models, you'll need to invest in a couple more round punches.
A visit to Michael's Craft store should provide you with the basic round punches in different diameters, but you'll likely pay $10, rather than $2. The advantage to the more expensive punches that you get from the craft store is that they have a longer reach than a standard punch. This comes in handy for sure.
Step 2: Pattern Punches
- ¼".rectangle punch (you'll notice that it's used for Harvey 2.0 on the the feet and the head)
When you go to the store to buy punches, you'll see many amazing designs like this. Don't be fooled. I bought a couple of them and they will only cut paper. The opening is not wide enough to cut craft foam. So disappointed.
Step 3: Leather Punches
An advantage of the hand held leather punch is that you'll have a lot of different diameter holes and you'll only have to pay for one punch. The only drawback is that your holes will no be as clean and quick to cut. The advantage of the hollow leather punch set is that you'll be able to punch holes up to ½" in diameter which will allow you to incorporate bubble tea straws into your designs. Again, the drawback is that punching holes with this type of set is a little slower than regular hand punches.
