Hi everybody
Today i go on with the gantry
I start by drilling the holes for the bf/bk on y axis. to do this i remove the 120X60X3mm middle tube of the gantry. I put the ballscrew on place and point the holes


Then i put the tube back to the gantry and start aligning the tubes with the steel plates. After that i start spot welding the pieces. With small weld in order not to produce muh heat



At this photo you can see the 1120mm long m8 bolts that i use to keep in place the side 10mm steel plates


After the side spot welding i had to weld the tubes at their side that atteced each other
First pass i start with spot welding every 10-12 cm. Second pass i weld between the old spot welds ( every 6cm) and so on.... In order to have better result i turn the gantry a bit


Finally i end with this result



Then i put the front steel plate on the tubes construction and temporarily i put the rails on, in oredr to see where to drill the holes in order to bolt the plate to the tubes



The only question i have is about the way i weld the tubes. Are these spot welds ( every 3-4 cm) enough or i should make a full weld

Thanks for your time
Any suggestion will be glad to hear
