The text appears to be a series of notes and updates from June 2018 to July 2018 regarding a project involving a bullet feeder. Here's a breakdown of the content: **June 5th** * A new adjustable test feet giving 45Deg+ but 45Deg is not a bad angle. * A totally new (mk2) flip ramp, 11mm taller to match taller collator plate, waiting in queue to print. **June 6th** * Collator plate seems Ok on 55gr flat base but for 62gr when inverted they are too unstable. * Designed a new nose guide for inverted 62gr projectiles. **June 7th** * A new deeper/thicker collator plate works really well with 62gr FMJs. * mk2 "improved" nose guide spacer done but may not now be needed. * Scraper for inside to "scrap" any more than 1 projectile out of a U slot. **June 10th** * Initial testing went fine, now doing a "proper" test print. The best angle is about 53Degrees. **June 11th** * Base printed starting to assemble beta unit. **June 13th** * Beta unit ready for testing. **June 22nd** * 5rpm motors arrived but may not be the solution. * Occasional jam as bullet is slow to drop into shoot as the "right" angle is hard to find (53Deg is too steep IMHO). * Added a bigger chamfer to the shute to try and fix this so base will need re-printing. **June 23rd** * Changed angle to 47Deg, almost faultless in 1000 rounds. * Currently running at 3rpm and 47Deg. **June 24th** * Uploaded a mk1 standalone stand that screws to the benchtop for the bullet feeder. * This way anyone can use it on any press with no changes or unique bits. * Needs a 20mm round dowel of length > 1m (to be determined). The project seems to have gone through several iterations and improvements over the past month, with adjustments made to the collator plate, flip ramp, nose guide, scraper, angle, and motor speed. The goal is to achieve reliable and consistent feeding of bullets into a press.
