- I can purchase white Styrofoam boards in 24-inch by 48-inch sections for about $5.00 USD each at Home Depot. I decided to purchase both 1-inch and 2-inch thickness boards.
- Apparently it is a lot harder to cut boards this thick compared to the 0.5-inch pink expanded polystyrene that I had been using.
- Therefore I intend to use a hot-knife. I chose a piece of scrap white-foam from my last gig.
- My first attempt was to rig up my 25-watt Weller soldering iron with a 8-awg copper wire. This doesn't not get hot enough as you can see in the pics below.
- My second attempt is that I purchased a 140-watt Weller soldering gun. I replaced the filament with 12-awg copper wire. The filaments are fixed into position with screws. This worked out well.
- Next time I'll start actually do something more interesting.
|This is some thick board!|
|I had thought this was a bright idea. Nope.|
Not enough heat generated.
|The result of poor planning is sloppy work.|
|Notice the melted plastic everywhere on the|
copper bit that I used. Not good.
|Attempt #2. More Pow-wa! 140 watts of danger!|
|The old filament is at the top. I created the|
one at the bottom by shaping 12-awg solid
copper wire. It's about 3-inches long.
|And the result is satisfactory! That piece is about|
1.25-inch in thickness. I'm happy.
