Dillon Case Trimmer (RT1200 or RT1500) Exhaust Manifold (62402)
Description
UPDATED 6/24/2020: On request, I updated the part that contains the M5 threaded brass inserts. This is due to the different types of inserts. The original ones are about 7.5mm on the narrow end that gets inserted, and 8.3mm at the top with an overall length of 6.7mm. The ones that are also common resemble a hollowed/threaded "I" with two splined flanges at each end. These can be 8 or 6mm deep, but are only ~7mm wide at the flange. To accommodate this difference, I have uploaded a new version of the A part ("_Small_Insert"). This "small insert" variant has a smaller diameter hole and is 0.6mm deeper, but the hole locations are identical so it should have no alignment issues with the B part. ----------------- For attaching a vacuum or shopvac to a Dillon RT1200/RT1500 trimmer. I was given a modified version of this that was altered to work for trimming shorter cases and the request was for a normal (unmodified) one (apparently, the owner has one but recently moved and doesn't know which box it's in). This is meant to fit in place of part 62402. The real part is not expensive, but if that's the only part you need, the shipping is comparatively substantial. Differences from the original: - The original used SAE screws, I used metric here. The B part is designed around brass threaded inserts to be melted into the plastic. Because of the brass inserts, I decided to not use a resin printer. - The curvatures were estimated, a substantial part of the original was missing so I couldn't take good measurements of what didn't exist... - The original uses some sort of saw-tooth structure around what would be the thick part of the trimmer (about 40mm), and when screwed down, the teeth squish a bit to the actual size of the trimmer. This version just has a 39.8mm hole with the idea that it would stretch to fit the 40mm and without teeth. - The bottom was missing, but I guessed that it's sized to fit around the 31mm diameter hex-nut that retains the die. It seems to fit Dillon and Lee (original hex) lock rings, but not Forster, Hornady, or Whidden rings, but those are basically round disks not nuts, so it can probably rest directly on the lock-ring/nut It uses: - 2x M5x12 hex head cap screws - 2x M5 threaded brass insert for plastics (there are YouTube vids on how to use them, I used a modified Hakko-type soldering iron set for 250deg C) Also, Duramic3D blue PLA+ is a close enough match to the Dillon blue of authentic Dillon parts. The original part is, I think, smoother injection molded nylon and from a surface finish standpoint, much better than PLA printed.
