First Cutting Job
« on: January 07, 2017, 03:15:35 PM »
Had to post this again because the pictures are too large.  This is my first run with the laser to cut parts for a model plane.  It took about 8 minutes to cut.  Most parts fell out some I had to use an exacto.  I will probably slow it down a little next try.

It was 1/16" Balsa - 2 passes left/right speed 30 up/down 25.....I was working with inches so I assume per minute?  I was running the laser at 100%.  I have a 2.5 watt.

No that is the next thing I have to put together.  I think I'm going to use an aquarium pump.  I have a small compressor but I don't want to have to set it up every time I want to use thelaser

cool.  I find the air helps remove the ash and keep the cuts cutting.  If you are having to cut a few with the exacto knife you might want to give them 1 or 2 more passes or cut the speed.  I usually cut at 100 mm/min dunno what that is in inches/min.  I also keep a sheet of metal under my cuts so I dont have to worry about two many passes eating up my workbench.  cant wait to see how the plane comes out

 25mm= inch

Lasers are wonderful machines..not ONLY  can they cut a finger off BUT  they can also cauterise it at the same time.....

SAFETY -  IS NO ACCIDENT

Thanks ross i was tired and didn't care. lol I usually only deal in metric or standard I try to avoid converting.  That's where mistakes get made and you plow a billion dollar mars rover into mars at 100000 km/h

Made the 3/32" parts sheet. This was softer balsa just below calling it medium.  I am cutting at 18/14 inches per minute at 100% power 2 passes.  It took about 15 minutes to cut and all the parts fell out with no exacto!  These lasers are a lot slower than the craft cutter but laser makes perfect notches...the slot in the fuselage piece where the elevator goes literally fell out with a slight push.  I have a aquarium pump coming tomorrow for air assist.  Since I could get away with it (SO not here) I put the laser on the stove and used the vent fan to pull the smoke away.  After air assist my next project is setting up a decent waste board.  Really cool!

A waste board is good. I use a waste piece of steel. No chance of it catching fire.

I am planning on using 3/4 MDF board and gluing down something like 1/2 in 19-Gauge Galvanized Steel Hardware Cloth so there is some air space for the laser to cut.  I have look around at Home Depot and see what they have.

I have been using the steel plate that come in an open diamond pattern. One really nice aspect is you can use magnets to hold the work. Ralph post a nice writeup of his implementation.

Here is that link to my post: http://benboxlaser.us/index.php/topic,1207.msg14836.html#msg14836

The magnets were @ggallant571's idea and it works very nicely.
