Well,it''s about time. Finally found time to run this thing thru the VMC. Vasco 250 Maraging Steel. Ohhhhh!!!!! I LIKE this stuff. Machines like butter. Cook it at 925 * and this is some tough stuff.stronger,springier than the Weddle
gears shafts in the 091. This shaft mates up tp the Weddle input shaft of same size. This won't be the weak link again.
Some specs for any interested:
Tensile 260,000
Yield 255,000
Elongation 11
Notch Tensile 380,000
Rockwell 48-52

Well, I dont understand a damn bit of those number that you posted, but I am imagining its a bit gooder than anything out there ;D
Nice work!!
-
Well,there is Vasco 300 and 350 also. A bit gooder yet. ;) ;D ;D Just extremely tough. Vasco 250 is next step up above 300M. Best part is that any fool with an accurate temp measurement capability (K type thermocouple and a t/c capable multimeter) and a kiln can heat treat it in a non atmosphere controlled furnace . All there is to it is ,cook at 900F +- 15 degrees for 3 hours,cool.
-
Sounds like good stuff, but what's the downside to it? Why isn't it used more instead of 300M?
-
I'm with Enemy on the Chinese, drowning. But sounds like it machines like plastic, cook it in my easy bake oven, and it turns into steel superman cant bend? Cool, Cool.
I'll bet its pricy, and why not more widly used.

Simple, about 2-3 times the raw material cost.

300M is just a modified 4340. Both 4340 and 300M require an atmosphere controlled furnace and some pretty strict controls to achieve one of many possible strengths/degree of toughness. In a production setting that is easily achieved but if )1 off pieces it is a bit hard to find a heat treater that is running similar size,thickness,shape pieces in batches to assure desired results. Not an issue with Vasco. ONE small drawback ,and a reason why not more readily used ,is that Vasco is limited in how hard (wear resistant) it can be made. At 260,000 tensile it will only harden to 48-52 Rockwell. Hard enough for moderate wear resistance.

those are some impressive #'s!!

That they are.

No doubt. Amazing!

not that it is the same but i was just working on a 944 porshe and it was front engine but rear wheel drive so just for grins and giggles I had to take a look underneath. here are some pics of how they took a mid engine trans or front wheel drive trans and made it rear wheel drive was my first thought till I noticed that the hole in the bell housing for the starter was upside down like the trans had been rolled so my guess is it was for a rear engine design first. here are some pics of what i found doing a real quick search. I wonder if that plate would fit a t1 trans?
-
I don't think it will fit but Tman should be able to say. Pretty slick IMO.
-
it was an interesting idea but still would take up more room than your design.
-
Did the HT (actually aging) of the vasco shaft last night. Did a Rockwell on it today and it hit a RockwellC 52. Max hard and max strength at that level.I couldn't be happier. Well,it's time to go back together now.
-
I personally think that will be more than you need and should work w/o issues. no you can find new ways to beat that rail! lol I do like the design of it and especially the h/L capability and compact design!!!!!!
-
That shaft is now an equal or better shaft than the Weddle shaft it mates to. Gotta find the next weak link.......... should be fun!
-
yep and i know you will one way or another!! rofl
-
Well,there's quite a few miles the Vasco input shaft now.Hammered pretty hard but until I'm in the sand,buried,and do something foolish like dump clutch in first at about 9+K like last time I won't say this has passed testing but I'm pretty confident about it at this point.
