Hot wire foam cutter table going to start building one.

How's your project coming along?  Do you have a rough sketch of what your table will look like?

     The top is an old leftover piece from a local cabinet shop. The framing and legs are recycled pallet wood. the top is connected to the framing with a 3 1/2 ft. hinge so you can get to the underside to change the wire without having to get up underneath it. The left side is a piece of hardwood to hold up the top. The loops are 1/4 20 to connect the wire and one is at 12in. and the other is 24in. for cutting bigger pieces. It works pretty good now that I have the right power supply and I took the 110 AC dimmer switch out of the power system. The power supply is from RS and it has a switch for 6volts, 7.5volts, 9volts and 12volts at 2.5amps DC. Choo Choo Kenny

Kenny,

I would love to see the how-to and progress for making the foam walls.  I am getting ready to make tunnel liners and haven't figured out the best or easiest way to do it.

Thanks,

Ed

Ken,

How does it work?  Exactly what does it do?  I have plenty of foam to cut and am interested in this.

Thanks!

George

     The power supply is DC and on the power supply itself is a switch for 6v, 7.5v, 9v, and 12v 2.5 amp. The power supply came from Radio Shack and to make it work you need a male 2 prong plug to go into the plug on the wire from the power supply. The 2 prong plug has the 2 wires coming out of it that I crimp connected to the wires going to the loops that hold the cutting wire.

     Well I am sorry but I put in descriptions with each picture but none of that information came up with the pictures. If you have any questions just ask or look up hot wire cutter tables on You Tube and people have videos on how to build them. That's how I built this one but mine is much larger than the ones on You Tube. The ones on You Tube are bench top models but I figured I would build mine bigger to handle a 4 X 8 sheet of foam board.

Your descriptions do show up in the bottom left corner of the pictures when viewed in their full size.

     Here are some pictures of the foam cut with a pattern. If you want straight lines you just clamp a board down to the table and use it as a straight edge. I tried to free hand cut the foam board at first and was not steady enough. 1st pic. is the pattern and 1 piece cut with the pattern. 2nd pic. is about 10 pieces lined up inside view. 3rd pic. is the same 10 pieces but from a side view. For the finish inside the tunnel I am going to use a cove router bit for the curved part of the walls and a straight router bit for the flat part of the tunnel walls and top. Choo Choo Kenny

     I would like to THANK  whoever posted on another thread a while back about using a guitar string for the hot wire cutter table. I did not want to keep paying big $ for the niacad wire so I tried using the guitar string and it burned up the power supply from RS that I paid $36.00 for. I am on limited income and I need to find a new cheap 12v 2a power supply somewhere and I need to get niacad wire that is also not to expensive any help? Thanks in advance! Choo Choo Kenny
