Nice work, I helped design your machine, The GFM-818. I did not make it though. You seem to have the original design, which is best. I hope you got a good one.
I sort of designed the machine and built it in my mind as i was trying to figure out how to cut stones during the start of Covid. And i built the machine in my kitchen... (3d immagoination)... sounds funny but really. Tne mast and handle i am using now.. the base is made in china but I had to radically modify it all around as it was a very very poor design and poorly made ( very low quality all around. I changed the gears, My own angle control with a digital angle finder and displacement measuring tool all added. even with all the modifications i did this mast and arm are still very very poor and i have to compensate in many ways. for now i will try to continue improving it until i can build a better mast and arm myself or buy a different one.
