zKars Posted March 16, 2020 Author Share #25 Posted March 16, 2020 Had a chance last night to go through the process and take pictures for posterity. Won’t be taking them in for plating any time soon. Get ready Use a little bushing I made to center. Squish! Cup made Turn die over, put cup underneath and squish the wings flat. Makes the machining steps easier 1 Link to comment https://www.classiczcars.com/topic/63655-source-for-the-cup-washers-on-the-su-air-cleaner-wing-bolts/?page=3#findComment-594459 Share on other sites More sharing options...
zKars Posted March 16, 2020 Author Share #26 Posted March 16, 2020 Part two. Use die to drill 21/64 hole Install on custom mandrel on the lathe and remove excess. Parted off to right length. Quick sand paper polish while it’s spinning. Flash clean up on the inner edge of the parted cut complete. 2 Link to comment https://www.classiczcars.com/topic/63655-source-for-the-cup-washers-on-the-su-air-cleaner-wing-bolts/?page=3#findComment-594461 Share on other sites More sharing options...
zKars Posted March 16, 2020 Author Share #27 Posted March 16, 2020 (edited) Final stage, a bit of dremel work to clean up any burrs and rough edges. Scratches on the back side need to smoothed from contact area on the mandrel. Quick abrasive rub, then sandblast for consistent finish. Off to plating with the next batch of hardware. Hopefully not too far in the future....

Captain Obvious Posted March 16, 2020 Share #29 Posted March 16, 2020 Awesome. When you said you were going to cut off the excess material on the lathe, I was going to suggest trepanning. I suspected that if you tried a traditional outside edge cut, there was no way you were going to be able to do that mounted on a mandrel like that. The interrupted cut would have made that impossible. Either the part would spin on the mandrel or the corners would have just bent over. Seems you're a step ahead of me! Looks great!

Given the tough position so many of us are probably in or going to be in soon, you can have 6 for $4k. Canadian. Good news is I’ll lots of time to make plenty. Got a big sheet of 18 gauge to gobble up. 1 1 Link to comment https://www.classiczcars.com/topic/63655-source-for-the-cup-washers-on-the-su-air-cleaner-wing-bolts/?page=3#findComment-594518 Share on other sites More sharing options...
Popular Post zKars Posted April 1, 2020 Author Popular Post Share #35 Posted April 1, 2020 (edited) Progress today. Cup washers are back from the plater. Look good to me! Now I have to go buy more plumbing rubber washers to complete them. By “go out” I of course mean, order on line. I found some at Ukrainian Tire. Coming next week. Never ordered anything from CDN Tire. usually it’s a reason to go out for a look-see, like Princess Auto or Harbour Freight....
