You'll still have to remove the greese cap to add greese, but when you do it will be through the zerk fitting into the center void between the inner and outer races. When you see the greese coming through the front bearing you know that it's filled.

I never thought of making my own, Great idea, but using the drill press with the spindles still welded onto the axle might be tricky. I found some spindles called EZLube and they have that arrangement. Wish I could do that with the good axle so the two match. I may be too anal, which is not always a bad thing when welding on an axle. What is the best way to line up the spindles, v-block or string it out using the hub face and axle as a reference? Stick with 7018 rod is what I was planning on using, waiting on parts. Any suggestions?

I only suggested a drill press so that it's a straight hole down the center..
You can do it with a hand drill if you're really careful.

I have no idea... Obviously you want the spindle to be 90 degrees from the frame so it tracks correctly, but I don't know what you're welding it to. If you have an axle stub then I'd think that, yes, a "v-block' is the way to go. Tack it in place, remove the block and let fly. Be careful to keep the welds short so you don't pull the spindle off center.

Stick with 7018 rod is what I was planning on using, waiting on parts. Any suggestions?

7018 is the stronger rod.. (70,000 lbs tensile as opposed to 60,000 for 6011). Depends on your skill level I think. I like 6011 because it has better penetration than 7018. It's great on rusted/painted parts.... and you can run it reversed polarity, which you can't do with 7018. But 7018 gives you a better looking finished weld and you can just drag it whereas with 6011 you have to keep the stick away from the metal. Straight in and J stroking it always seems to work best for me. That's a really rough call. If the metals' clean I'd go with the 7018. If it's dirty/rusted then the 6011 would be my choice. You could also use 6010 which is a fast freeze rod (which means the puddle cools and hardens much faster than 7018). Useful on vertical welds.

Don't forget..when welding vertical from bottom to top (which is how any experienced welder should), don't be hesitant to move a half an inch out of the puddle to allow the molten metal to harden. It makes it easier to run a consistent bead. When doing it, move upward (out of the puddle) so that you cover up any chicken scratch that is created. It makes stick welding in vertical positions (especially the root pass) much easier. It takes a few times to get it right, but you'll use it for a lifetime once you figure it out.

Hope this helps a little...

You are a life saver, Destroyer. I wasn't trying to deminish your excellent idea, I was just poking at you about drilling the axle with the drill press.

The substrate is clean like new. I have Square 2" OD Galvanized Tubing with stubs that fit inside and get welded in place. Thankfully I will be doing the welding on a heavy duty worktable at a comfortable height (ie no vertical welding because it always looks like a$$ when I am done, I need some serious schooling/practice on uphand vertical, thanks for the tip). If I knew in advance I would be welding vertical I would use the mig next door. Actually I still might use the mig, depends on when the parts arrive. Any drawbacks? You sound like the man to ask.

The more I think about spindle alignment the more I think a straight edge and a micrometer may be the ticket. In any case it will be close enough. Worst case scenario, a little extra tire wear, I can live with that since the tires tend to dry rot before the tread is gone anyway.

No offence taken or even considered... :) (poking is always cool)

My only concern with Mig is the danger of light penetration if you're not careful with your heat settings. Stick is old school, but old school is still the weld of choice for good solid welds. Most industrial maintenance is still done stick... quick, fast, portable, strong. But to be honest, I wish I had a mig unit I could call my own...lol

The stubs are going inside the sq tubing? In that case they should fit just fine... If they are a little sloppy, tilt the tubing on an edge until it looks like a diamond <> and use that inside "V" to hold the stub in place parallel to the tube...then clamp and weld.

(And don't worry if your trailer is next to you as you go down the road... that way you can keep a better eye on it.)

Still waiting on parts. Meanwhile I took the hubs off the otherwise good axle, now I see why they went bad. Bearing and races on left side looked good but the right side inboard bearing was junk. Several missing pieces off the rollers and rusted. Not as much grease in either side IMO. Water got by the seal and was working on the innermost bearings. Replaced races, cone bearings and seals but it looks like the three day weekend will be spent without the Wellcraft. My stupidity, I will just have to deal with it by using one of the others;-)
I knew this boat sickness that I have would come in handy, sometime.

The parts arrived. I got the spindles welded back on the axle tube and they are as straight as I can make them. Used a straight edge and a micrometer off the straight axle tube A better picture of the bad spindle and the axle bolted back under. Sprayed Corrosion X all over the 2 yr old rusty springs.

Nice job Ridge, Grease, never install brakes and you good for many years. Nice job on the welding ..
