While searching thru old boxes to glean parts for this amp build I found another unfinished project.
A few scraps of aluminum and a few holes on the mill....
I now have a very slick turret lug press.
I've always envisioned making an eyelet press and a punch to make quick fender style boards too.

nice work.

That is slick!
And a scalloped turret board for filter caps? Nice!

C'mon dude, stop showing off. :laugh: (actually, I'm jealous of your skill) Nice work!

That is very nice workmanship! But the staking parts are upside-down for me. I like to load all the turrets at once then go to the press to stake them. I have the stationary pointed piece on the bottom and the lug 'receiver' in the drill press chuck. This method seems backwards at first, but makes a lot of sense after you pick up a bunch of turrets that have fallen out of the board!

They still fall out LOL.
When I watch Doug's video, he seems to have to push the turrets in pretty hard. mine seem to just fit.
I've tried a #42 bit (.0003 smaller) with the same results.
I think when I build the actual board,I'll use a #43 and hope the runout in my drill press opens the holes for that snug fit.
Making a new set of dies for it won't be a problem either (inverted).
I'll also be able to use a better quality steel like 4140 pre-hardened or maybe some A-2 and harden them at home with a torch and oil.

I had a project at work, they couldn't find a material that was hard/stiff enough to hold rows of small parts that was non-metalic.
I suggested LE grade phenolic and it worked pretty well.
when I built it and saw those short fat rods lining up I knew how I was going to build that cap board.

Your press looks great!

I load the whole board with lugs and then go to my press
The tool with the hole is on top in the drill press chuck on mine
You can load and swage boards way faster this way than doing one lug at a time
