A short posting with pictures of variable capacitors made using a CNC machine by 9W2CEW. The CNC cut both the rotor (moving plates) and stator (stationary plates) in one go. Refer to the last picture below.
This design is usually found in loop antenna to change the capacitance value from the shaft.

superb
ReplyDeleteNICE GOING. BIG VARIABLE CAPS GETTING TOO COSTLY + YOU CAN "ROLL UR OWN" TO FIT UR CKT.
ReplyDeleteLooks interesting to me! What was the capacitance (range) you are getting with this?
ReplyDeleteMy next blog entries have the capacitance values
DeleteIf you do not mind.
ReplyDeleteCan you share Aluminum Laser cutting drawing file.
