RE: Todays Project - What did you do today? - Vinny - 07-05-2015
They showed up.
RE: Todays Project - What did you do today? - oldgoaly - 07-05-2015
Nothing to exciting, a friend in Maryland was selling some Trumpf nibbler tooling, I don't have a Trumpf but have a Pullmax or two. So this is how Trumpf makes them for offset / joggling helps stiffen flat sheet.
[attachment=11240]
how they would work in the machine
[attachment=11241]
my setup, small vise on a 8" palmgren rotary table on a old BP
[attachment=11242]
I took light cuts till I got the set up "debugged" tightened up!
[attachment=11243]
[attachment=11244]
still need to weld shanks on to them, trying different depths on the flats surface, the joggle depth is .060
may make another set or two with little more offset depth, but want to try them out 1st. See if there any major fubars!
[attachment=11245]
RE: Todays Project - What did you do today? - PixMan - 07-06-2015
Nice work! Now why wouldn't you have made them out of solid round and milled the square shank? That would have been my method because I know I don't have a good welder.
RE: Todays Project - What did you do today? - oldgoaly - 07-06-2015
heck mig is easy, make it sound like bacon frying it's welded!
the force on the welds is not much, it just keeps the shank connected to the die, have not had on fail in 20 years.
oh but I've bitched plenty on how well a tack weld held trying to get it apart.
I'm also using CO2 shielding gas, seems to work better than the mixes, no I don't do the newer hi-strength steels.
RE: Todays Project - What did you do today? - Vinny - 07-06-2015
What flowrate do you use with CO2?
RE: Todays Project - What did you do today? - f350ca - 07-06-2015
The processor isn't close enough to finished so cut firewood all day. One good workout in this heat.
RE: Todays Project - What did you do today? - dallen - 07-06-2015
made this little cutter today
[attachment=11256]
its for cutting a radius on the ends of the part on the right in the of the two pins, which have been profiled to match the above cutter
[attachment=11257]
RE: Todays Project - What did you do today? - PixMan - 07-06-2015
If I understand what I'm looking at David, that's a rather challenging part shape to do with manual machines. Tell me more about the part and the process, it appears well done, as all of your work is.
RE: Todays Project - What did you do today? - Kennyv - 07-07-2015
its not much ....... but finally finished painting last parts so now can put the Band saw back together.. Tonight or whenever need to mill leg base angles and Hog out the arches in leg bases .. and I aint painten them they are goin on saw base bare bone allum.. besides today is 80' humidity take 4 days for the Forged hammered paint to dry .
As ya see Gots some nice mag wheels now and even painted the handle "BRIGHT PINK" for Dave and Vinnie
Io IO ....... off to work im glad this project only cost me $17 .. had to borrow a few $ this morn from Home Eq to pay Junes mortgage....

the part wasn't done on a machine but rather with a jewelers saw, which took 5 blades to cut it out as the .025 blades kept breaking cutting the 11 gauge plate that I used to cut the button from.
here's a photo that I snagged off the internet showing the part in place over the pins.
[attachment=11274]
the pins in the photo actually have the side cut off so the button has a square shoulder to set on. These were done several different ways with the way that I'm doing it (which is whats shown on the print that I have show) because I want to pins and button to blend together in the joint line.
hope I got that were someone can understand it.
Also the heads of the pins in the photo are extremely thick for that they have to do, Pins in an original stick up barely a 1/16 of an inch. Which means that once I get the ends of the button (Remingtons name for the retainer) cut to fit the pins then I have a bucketful of filing to do to blend the end into the pin head.
