Nice. What are you using for the vacuum pump? I love it when people use their CNCs to make their own equipment rather than buying it.

i am using a gast pump 1/3 hp

also after i machined the plastic which is not like wood ,then i drilled and tapped for the brass barb
The next batch will be barb fitting on either end so all four hook up in series
Again the work piece texture is important the glass was the best ,the pump was pulling 20 in and with the plywood it was 18
And i have used a 1/8 pegboard if i have to cut through as you do not want to damage the oring
