Our CNC Router can cut slots in Blue Tube Airframe up to 7.5” in diameter.
Available Slot sizes are: .0625 –.093- .125 – .187 -.250 – .375 – .500.
Please provide the following dimensions in thousandths of an inch and enter in the “Order Notes ” section of the Checkout Page.
Our CNC router utilizes a twin flute square end mill to cut the slot. Some filing is required to square the opposite ends of the slot. A round end mill cannot cut a square hole.
**Important Note**
The slot must be offset a minimum of .250 from the end of the tube to insure integrity during shipping.** To have the fin slot begin at the motor end of the tube, simply subtract the offset mentioned above from the length of the fin slot. You can then cut the tab after the tube is received.
