Re: Fw: [projects-in-metal] A $5 2 axis DRO for a small drill press
|
My Clausing lathe and mill will get DROs in due time. But this will be my 'go to' for things like small boxes and front panels as it will be configured specifically for that all the time whereas the mill may require a good bit of set up depending upon the last job I did on it. Normal machine shop tolerance is 0.005" which is slightly more than the 0.1 mm resolution of the plastic calipers. The plastic DROs are more than accurate enough for panels. The green XY table cost under $40, so the table and calipers for the DRO setup cost less than $50. I used the little HF drill press simply because Dad left me several including one he took apart and reassembled upside down mounted on one of the support columns in his shop minus the base plate.
