I made a little mistake grinding my e-50 case for an 80mk, long story short it needed to be welded. My local welding shop tried and said it cant be done because it is crappy metal. Does anyone have any imput or suggestions.
thanks

jb weld
I have it done all the time, take it to another welder, it has to be tig welded.
Yeah your local wleding shop is a bunch of dumbasses. Tig would be the best way.
Jb weld industrial strength. Good up to 600 degrees. I fuck up all the time.
they did try tig welding it, and said it is crappy aluminum, and it cant be done. Have you used jb weld where it is exposed to gas and oil? like inside of the case?
yes. my gilardoni kit is jbwelded. err rather, the cases.
Has anyone tried jb weld and had it not work? I dont want a chunk breaking loose at 7000rpm and destroying my kit. Kellym how long has the gilardoni been running like that?
Find a new welder! Seriously, at least have 3 guys say they can't do it before you venture into JB Weld world. Although, being from Nebraska, it wouldn't be an uncommon idea.
Paz had it done, I'm having it done as we speek. get a second opinion.
I ran a regular cyl skirt on a case I bored for a Gilardoni by sleeving the cyl studs with wrapped paper and tape to center the cyl and it worked fine. Primary compression will be a little more loose but top end will be slightly enhanced
Oh yea JB Weld works fine. Sand the surfaces. To get a tight fit put wax on the cyl skirt then fill the space between case and cyl skirt and the wax will release beautifully when it cures. Do 1/2 case at a time
My friend scott, who does all my tig welding for me has welded up two E-50 cases no problem, one Sachs 505 case no problem, and even repaired a cracked puch Snowflake, not a problem, It is cast aluminum, but that doesn't make it bad metal, just a crappy welder. search out a differnt welder, even if it is a drive and a half its better than half assing it with JB weld
Thanks for the advice guys, I found another welder who has done some harley engine cases and he doesnt think it will be a problem. I'll let him give it a try.
The shop you are taking to case too needs to be removed from your list of people you go to with projects.
When I dropped off my first case to my machinist he said sure I'll take care of it. A week later he handed it back to me with layers of weld looking like stacked dimes, He has done like 5 cases for me since then.
If a welding shop says they can't do it it's there lack of skill not the quality of the aluminum.
Also you can Tig or Mig aluminum as long as you have the correct filler metal.
Beadblast the case.. I would of grease .. and crap in the metal..
you want it super clean .. welding alloy is a must to be spotless surfaces.
It was spotless, I think the guy that tried was just an idiot. I will take it to another guy tomorrow I will keep you posted.
WOW I never thought I'd be able to correct Mr. Chris Paz, but I'm afraid you were wrong my friend. You can MIG carbon or stainless based on the filler rod, but aluminum MUST be TIG'd, there's just no getting around it. It has to do with the TIG being operable as AC and MIG being DC only. YAY, I feel smart now. Thanks SCAD.
BTW, I'll be emailing you later this night homes, just been mega-busy with school and whatnot.
Taylor your are full of shit MIG works great on aluminum your welds just won't be as clean and pretty. and depending on your MIG rig it can be AC or DC. it depends on the filler wire when doing MIG aluminum, again it wont be as pretty but it can be done, If we had to tig all the signs and my shop we'd be out of business, MIG rules, right under TIG
Yes absolutely , You can weld on aluminum with a Mig . I use a spoolgun and straight Argon . Been doing it for years I do it all the time , Oh , like about 2 hours ago on some aluminum lawn furniture . If you can't afford the spool gun , you can still run the aluminum wire but just mke sure you don't bend the Mig cable too much - keep it as straight as you can so the wire feeds properly and use straight Argon . I finally broke down and bought a spoolgun because I had to weld up an aluminum boat and I couldn't get into the tight areas. Try and find the closest aluminum alloy wire to what you're welding and weld away . Your welder may be thinking of pot metal -
Also , a cheaper alternative is the local junior college welding shop. I've never really heard of an AC Mig but that's just me most are DC with reversible connections . Also if you're really rich High Freq Tig is the real way to go .
Sorry Taylor, maybe some other day... :P

yep What he said ............. ^
I dropped the case off at a more competent welders shop this morning. He didnt think it would be a problem, even fixing the other guys fuck-up.
hooray!
well MIG's are for tackwelds, jigs, or people who suck and have no control to TIG... yea I said it.
So go point and blast with your mysterious AC MIG and try to control it enough to build up a consistent bead on aluminum, and good luck to ya. I guess I just learned the right way, not the ghetto backwoods blind-blaster way. Fuckers...
From the link:
The truth is that with practice, the right equipment and proper set-up, a compact MIG welder will be able to tackle occasional aluminum welding jobs. Using your MIG welder, you will be able to work on a variety of items around your home and yard, such as grills, yada yada yada
By practice they mean LOTS of practice, and wasted e50 cases if you actually hope to use one of those little buggers on one. And Uhm, have you ever seen an aluminum grill? I didn't think so.
(and just to clear up my smart-assedness, it's all in good fun)
has anyone used a spool gun on a puch case yet? Most cast aluminums have a very high silicon content, making them very hard, and also very 'watery' when they melt... i'm used to welding crap, so i've never had much of a problem with it. some guy who welds on an assembly line all day probably wouldn't like it.
my roomate has a spool gun and i was thinking it would be nice to have set up at home, if i could do cases with it, so i wouldn't have to duck out of work to get my welding done.
Hehehe...... It's not that I'm a crappy welder to be worthy of a Tig , I'm too poor to afford a nice water cooled high freq Tig setup . Heliarc works well too on aluminum alloys . Tig got all the attention and popularity over the years from all those hotrod and motorcycle shows . But I'm with you , never JB Weld - If it gets you up and running ,rather than walking great , but fix it right when you reach civilization it eventually fails . Good stuff to make bullets out of when you don't want them traced and cuts real clean. Tumbles real good too.
