Remix/Modification of the Bulk Film Spooler by nevillefrancismorris. The design he had included a spindle to hold the film roll that was too thick for Ilford bulk rolls. So, I decided to non-destructively modify his designs to include a thinner and more durable metal spindle much like commercial bulk loaders.
NEEDED PARTS:
1- 2inch by 1/4 inch bolt. I got mine here: https://www.amazon.com/gp/product/B07QDTM6F3/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
1- 1/4 x 20 pitch threaded heat inserts. I had some lying around for doing other photography stuff since this thread is the same as tripod threading:

Some superglue
INSTRUCTIONS:
Simply insert the bolt through the screw cap, and screw it into the thread on the bulk loader. I used some superglue to secure it down to prevent the bolt from wiggling further.
For the modified bulk loader cap, place the knurled insert slightly into the open hole, and using a soldering iron press it into the hole, making sure it sits flush with the rim. You can also press fit it in with some force, and use superglue to secure it down.
