Nice job

Looks pretty darn nice. Only one question- is it your laser cutter or someone else's? I want to get one someday if I have the money just to say I have one. That seems like it would be fun.

Unfortunatly these machines are very expensive, the one who did this job is a professional laser cutter of a friend that have a Lightweight carpentry, it costs about $ 500,000, extremely accurate, with 3000X5000mm cutting area but the laser cutted pieces ar very cheap, just $50 for cutting a sheet aproximatelly of 1500X2000X1 mm with small piece like this including the cost of the metal (ridicolous).
With this method i make some stuff like this special wrench made from 4 layer of steel tack together

Very nice, would like to see a video of this operating

Here a short video of how it's working made on my garage, non a very professional welding table , simple regolation of speed by a H0 train transformer with reverse switch, on the floor:
on the left there is the foot switch connected whit spindle motor (regulation of the speed with on/of on the pedal ), on the right the tig foot pedal, right hand tig torch, left hand filler rod and let start welding; and then say that welding aluminum is difficult, never try this

Good deal, nothing like a successful DIY
