I just wanted to reflect on the table maintenance I performed today and give a little report after having my table cutting for 36 days now.
At 36 days I have cut through 6 (4’x8’) sheets. 2@ 14 gauge, 2@ 16 gauge and 2@ 11 gauge. I have sold just under $4,000. Not everything I cut or attempted to cut survived. I did come into this with a year of prior CNC experience. I ran my brothers granite shop, programming and operating a 3 axis router and 5 axis saw. I have a degree in petroleum engineering and learned basic solidworks in college.
Biggest seller without a doubt is trailer hitch covers. Makes sense though because everyone here in Texas has trucks but not everyone has a trailer. I like cutting these out of the 11 gauge material because it’s more forgiving when I weld them onto the square tube. I just learned to weld from YouTube 2 months ago, I’m getting better every time though. I usually have about $8 dollars worth of materials and 30 minutes worth of labor. I sell the non-personalized ones for $40 and the personalized ones for $50-$100. It’s certainly not a home run but I’m getting my product on the streets and I’m learning as well as gaining experience.
I have a job coming up that is more in line with my goals. I’ll be cutting small rectangles with 2 holes in them for mounting. It’s for a large commercial fence company and the material is provided. I’ll make $300 on each sheet I cut. They have an initial order for 8 sheets. Again, not a home run but it’s a hit.
Problems, my machine torch died on Christmas weekend. Hypertherm was very easy to deal with. I told the tech what I had done for troubleshooting and he said my torch lead was bad and he overnighted me one. Last weekend my table quit working and a quick call to Langmuir on Monday, I put the new power supply in today (Tuesday). I expected issues, it’s just the nature of CNC machines. You have to be willing to work on things.
Now to the maintenance. I’ll post about it a little later. Gotta eat
