This looks good, but I have to agree with Wolshadow001 on the triangle drill head. Mostly because the appearance of the machine its self is pretty impressive until someone looks at the drill head and drill bit. I say this because the machine looks like its using a giant screwdriver. I hope you understand.
love the scale and detail but might i suggest an alternate to this unless it is just for making rivets for screws and bolts?
the triangle drill head is potentially much more effective at grinding and drilling through the hardest substances, my dad is a blaster and when ever they ditched cracked drill heads mid work he would bring one home and ended up using a pair for anchors lol
