Thinking that the most labor-intensive part of the restoration of Mitchell 46 was behind me now, I was supposed to be at the point where I reassemble the working components of the camera, set everything so it is in time, confirm that the camera is now complete, and take it all apart one last time for painting. However, this was apparently not to be just yet. By way of explanation, the main shutter shaft on the Mitchell Standard fits between 2 adjustable bearing races that thread together in order to remove any backlash and keep the main shutter shaft centered to the overall drive components. The previous modifications somehow removed the rear bearing support, filled the holes that they mounted to, and held the rear bearing support in some mysterious way.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-4 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-1-1.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"1080\" data-id=\"1269\" src=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-1-1.jpg\" alt=\"Replacement rear bearing support for Mitchell 46.\" class=\"wp-image-1269\" srcset=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-1-1.jpg 1080w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-1-1-300x300.jpg 300w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-1-1-1024x1024.jpg 1024w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-1-1-150x150.jpg 150w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-1-1-768x768.jpg 768w\" sizes=\"auto, (max-width: 1080px) 100vw, 1080px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-2-1.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"1080\" data-id=\"1270\" src=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-2-1.jpg\" alt=\"View of the inside of the back end of Mitchell 46 and the 3 mounting positions for the rear bearing support that have been plugged.\" class=\"wp-image-1270\" srcset=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-2-1.jpg 1080w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-2-1-300x300.jpg 300w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-2-1-1024x1024.jpg 1024w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-2-1-150x150.jpg 150w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-2-1-768x768.jpg 768w\" sizes=\"auto, (max-width: 1080px) 100vw, 1080px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-3-1.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"1080\" data-id=\"1271\" src=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-3-1.jpg\" alt=\"View of the front of Mitchell 46 where the shutter bearing race is located.\" class=\"wp-image-1271\" srcset=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-3-1.jpg 1080w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-3-1-300x300.jpg 300w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-3-1-1024x1024.jpg 1024w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-3-1-150x150.jpg 150w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-3-1-768x768.jpg 768w\" sizes=\"auto, (max-width: 1080px) 100vw, 1080px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-4-1.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"1080\" data-id=\"1272\" src=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-4-1.jpg\" alt=\"View of the cone-shaped bearing race on the shutter and its position on the shutter shaft.\" class=\"wp-image-1272\" srcset=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-4-1.jpg 1080w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-4-1-300x300.jpg 300w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-4-1-1024x1024.jpg 1024w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-4-1-150x150.jpg 150w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-4-1-768x768.jpg 768w\" sizes=\"auto, (max-width: 1080px) 100vw, 1080px\" \/><\/a><\/figure>\n<\/figure>\n\n\n\n<p>My job now was to reinstall the main shutter shaft with a replacement rear bearing support, indicate the main shutter shaft so it is running true and parallel to the shutter\u2019s drive components, drill and tap new mounting holes for the rear bearing support, locate dowel pins, and begin reassembling the camera. The back end of the shutter shaft is threaded at 40 threads per inch. The idea behind this being you could micro-adjust the rear bearing race so the main shutter runs as true and friction-free as possible. This is where my whole day fell apart. The rear bearing race would Not thread back onto the shutter shaft. Rude! So until I can solve that problem, the project is at a standstill. The problem appears to be the threads on the shutter shaft itself, and because this is such a fine thread and the shutter shaft is an irregular shape, I am not yet sure how to repair the threads.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-5-1.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"1080\" data-id=\"1273\" src=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-5-1.jpg\" alt=\"View of how the shutter shaft and bearing races should be assembled inside the camera body.\" class=\"wp-image-1273\" srcset=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-5-1.jpg 1080w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-5-1-300x300.jpg 300w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-5-1-1024x1024.jpg 1024w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-5-1-150x150.jpg 150w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-5-1-768x768.jpg 768w\" sizes=\"auto, (max-width: 1080px) 100vw, 1080px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-6-1.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"1080\" data-id=\"1274\" src=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-6-1.jpg\" alt=\"View of the rear shutter shaft bearing assembly and how it is supposed to thread together.\" class=\"wp-image-1274\" srcset=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-6-1.jpg 1080w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-6-1-300x300.jpg 300w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-6-1-1024x1024.jpg 1024w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-6-1-150x150.jpg 150w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-6-1-768x768.jpg 768w\" sizes=\"auto, (max-width: 1080px) 100vw, 1080px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-7.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"1080\" data-id=\"1275\" src=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-7.jpg\" alt=\"A close-up of the threads in questions that have caused all of my troubles.\" class=\"wp-image-1275\" srcset=\"https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-7.jpg 1080w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-7-300x300.jpg 300w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-7-1024x1024.jpg 1024w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-7-150x150.jpg 150w, https:\/\/cinemagear.com\/blog\/wp-content\/uploads\/2022\/07\/mitchell-46-7-768x768.jpg 768w\" sizes=\"auto, (max-width: 1080px) 100vw, 1080px\" \/><\/a><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Why is it that the jobs that are supposed to be the simplest always turn out to be the most complicated?
