The quick rundown

So for this week I want to make a Puffin head.
The idea is to use the Puffin 3d scan from the 3D scanning and printing week for making it. The plan is to use it as the front of a boat, like in the old days when some ships had mermaids or dragons.
You may be wondering, why for a ship??
Well, it was not really my idea. You see originally we had  no plans for the week but the director of Leikfélag Vestmannaeyjar´s rendition of Spamalot reached out to me and needed something very specific for one scene. He needed a puffin head for the front of a boat, not an actual boat but a stage prop.
So the main challenges I face this week are:

• Choosing the perfect material
  
• calculating the exact measurements
  
• Making it look cool
  
• without making it heavy enough for the actors not to be able to lift it

Our beautiful milling machine:

Preparation

in the 3d scanning week I scanned a puffin. This week I am using that 3d scan and slicing it into a big puffin head. First I opened slicer for fusion and put the Stl file for the scan into it. I then put the desired height and selected 9mm crosswood as the material
s

This is what it gave me:

The red marks pieces that dont work and so I had to remove a few pieces and changing the angle. This took a long time and was honestly overall not an enjoyable process but after a while it turned out like this:

Here are the settings:

Puffin head

First we reviewed the safety and stuff. We screwed the wood onto the machine and then began testing.
            Wood thickness: 9mm

Here are the steps to our wonderful milling machine:

• ⚠️ Check out safety rules ⚠️

• put correct bit in

• Turn machine on
• Press reset button (blue)
• Turn off virus real time protection

• Unplug ethernet cable
• Open SHOPBOT CONTROL software
• Press K for Keypad

• Do the xy zero routine.
  

• 

Press K  and move to the new zero

Put Z plate and check connection

Z zero routine/(hold elephant clip on the material and let the machine find the Z zero

Move to a safe position and height
Cuts-> Spindle warmup routine

Testing testing

We started by making 2 pieces to see whether it would work . Whether the size is accurate. We imported it onto V carve Pro
The first test did not turn out perfect, the machine only made the hole 8mm thick despite the computer calculating it as 9mm.

So we simply changed it to 10mm in the machine and  the next test worked!
It was ready for the big job!

I then made a bunch of tiny circles for the machine to drill.

After milling

Assembling it took some time and effort. I used a sledgehammer to put it together. This was after sanding it down with sandpaper.

Final result:

Emergency Information
1. Injuries: . Do not attempt to remove foreign objects from the eye or body; it is better to have trained
medical personnel remove foreign objects from the eye or body.
Being ready to work
2. Do not operate equipment unless you have been properly trained to do so. If you’re unsure about
the safe operation of a tool or any aspect of a job – ask for help. If you can’t do a job safely, don’t
do it!
3. Never work when you are impaired.
4. Be prepared and have your file ready and plan ahead before coming to the Maker Lab.
Personal Protection
5. Never work alone. At least two people must be in the lab at all times when operating power tools
and equipment. An approved Maker Lab Supervisor must be present.
6. You must wear safety glasses with side shields at all times.
7. Hearing protection is recommended.
8. Must wear appropriate apparel. No loose clothing or jewelry, closed-toed shoes, hair tied back.
Shop and Tools
9. Always keep aisles, exits and access to emergency equipment (fire extinguishers, fire alarms,
first aid kit) clear at all times.
10. Become familiar with how the ShopBot works and the dangers before using it. Ask for help!
11. Verify the overall condition of the equipment and the material being used (e.g. condition of
bits, debris buildup, defects in the tool housing or anything that would compromise the safe use of
the ShopBot).
12. Keep the area around the machine clean and free of clutter and trip hazards.
13. Pay attention to the machine at all times.
