Chosen Solution
I purchased this tool kit at an auction. when I attach a sawblade it eventually loosens. I put a rubber washer in and that seems to help it stay together. It appears from the manual that I have the correct parts. I need to see one properly assembled to verify i am not missing anything and have the correct blades (as i have seen several different types).
The illustration is here: Fein Multi-tool MSXE636II (1963) There is an Upgrade Kit available for older Fein Multitools (MSx 636, MSx 636-1, MSxe 636 II) that improves how well it holds the tools. Upgrade Kit: 35222927050. https://www.burnstools.com/35222927050-s…
