Dillon RL-550, XL-650, XL750 Powder Measure Quick Detach

thingiverse

Note: Model is in Inches. Most slicers need to scale to 2540%. UPDATE: I visited my local Ace Hardware and browsed through their collection of springs. I've attached a label with spring dimensions (21/64" X 1-1/8", .028" diam) that seems to work best without needing to be cut down. I'm waiting for my Dillon 45 ACP powder funnel to test with flaring the brass. Parts list: A) Qty. 2, 10-24 x 1.5" button head screws (socket heads will need a washer) B) Qty. 2, 0.201 to 0.350 OD springs Approx 1.125 to 1.250" long (Wire diam between .025 to .045") I was gifted a lovely reloading setup with a Dillon RL-450 progressive press that hadn't been touched in 15 years. I've set out to slowly upgrade her to the 550C, albeit I only have the frame left to do the conversion. That being said I got the ram actuated Dillon Auto Powder dispenser and wasn't too wild about the socket screw clamp that holds it in when needing to change funnels (remember my RL-450 does not have removable die carriages). I saw a couple of other folks make similar designs that use springs and extra long set screws but I wanted to have a finger loop to ensure I could have a good hold for having relatively heavy springs to provide the clamping pressure. I'm currently trying to find a good referable source for the springs to use which is why I've marked this as a work in progress.
