The steam holes can be done by hand if attention is paid to angling the drill bit on the three angled holes on the intake side, and a starter bit is used to to start the hole straight down to make a small indentation to use to keep the bit from sliding as you lay the drill over to the correct angle, as mentioned above. The three holes that are drilled straight down are not a problem. Steam holes can also be made using a drill press equipped with an adjustable table. | The steam holes can be done by hand if attention is paid to angling the drill bit on the three angled holes on the intake side, and a starter bit is used to to start the hole straight down to make a small indentation to use to keep the bit from sliding as you lay the drill over to the correct angle, as mentioned above.
