Getting Close to 1000 HRS
I've had my machine for close to 5 1/2 yrs totaling 1000 hrs. The y truck was stuck so I took this opportunity to rebuild my cut motor which has
had no rpm sensor since the very beginning.
I got my mcahine on ebay reconditioned for $1000, with no warranty.I've paid $1851.00 for parts and bits since then, so total
cost is : 2851 or at least $3000 , if i figure in bits and bearings I bought from 3rd parties. So that's less that $50.00 per month for machine, consumables and replacement parts.
