Weld up the egged out part and get the router bits out and re-round it. Or weld the hole up and re-drill. I've done both. Actually, just did something similar on JD pivot bracket. It had a 1/2" steel boss on a 3/16" or so bracket with a .502 hole for a shouldered bolt. . I elected to just cut...
Use mine almost every day, and I'm retired! You have any equipment at all for outside, it's GOING to break. Just finished putting new bearings in a deck just an hour ago.
Didn't realize you were here until just recently. Pretty sure jack is Japan. The jack and the porto are both probably from early to late 80's now that I think of it.
Since we now have someone FROM Astro here with the straight story, I'm just curious if you have access to seals for Astro 4 ton porto power stuff from maybe the 90's. I contacted the company but got luke warm to HUH? type answers. I have an older Astro 4 ton that the seals blew in the primary...
Little mini saw that I use a lot. WAS my dads, now mine, and I'M 71. Couldn't find blades the right size. Everything I found was too long by about a quarter inch so I mig welded in a section to use standard blades.
I use my SPEED HANDLES a LOT more than I would ever use those wrenches. I alwas thought they were broke! I use my speed handles to run the bolts in on oil pans so they don't get away from me. Also use my 1/4" handle to get the side bolts out of the John Deer side covers. It's easier than...
Personally, I'd just use a pipe wrench and sad out the scratches. You're going to refinish it anyway. Antenna escutcheon socket from the 80's is really close though.
I LIKE to use cutoff wheels if I have one handy, and I usually do! fast, easy, and don't leave that ridge like tubing cutters. If the cutoff wheel isn't available, just a hack saw. Usually use a rat tailed file when I can't see the reamer.
My best is my CP/SKIL model 723(CP) or 1120/1123(SKIL) impact guns. They are 3/8" drive and you can get them into places no other impact can go. My collection NOW counts to 10 so I'm done.
