Lathing the gauges

the start if the largest gauge, the chest gauge, made from a large bar of alluminium

after facing off the exess material, I set about making the angled im around the egde

next I bored out a large hole, this will help when it comes to boring out the whole cavity of the gauge

I used this boring tool to work from the inside if the hole that I just drilled, working from the inside to the outside of the gauge

 Finished shaping the gaug now, just parting off to do, I repeated the steps to make this gauge for the next one also
