Questions for my metal working / tool repair buddies

I bought this saw on Ebay because I think I can make cross cuts by hand instead of on the table saw. And .. I want to be able to miter accurately as well.  I chose this one because .. well .. it looked well used and cared for AND because I want to use it.  Collecting doesn’t do much for me.
So what and how much to clean and repair?
First, there’s a small crack in the frame and the back foot is broken off.  Some one recommended JB weld to fix these item (since I can’t weld nor do I have the equipment).  I do, however, have a friend who welds although he’s new to it.
Here are my questions:
  • What’s the best way to repair the crack?  I was thinking “spot weld” on the back side of the frame.
  • Should I have the foot rebuilt and if so, any suggestions on how to do that?
  • Cleaning.  There doesn’t appear to be a lot of rust just a layer of greasy black “something”.  Maybe its original paint or added later paint.  Should I clean it or just leave it.

  • Thoughts on assessing and lubrication the saw holding mechanism.  It works fine as is, but I want to make sure it stays that way.

  1. Does the crack flex in use? If it doesn't JB would make a decent filler, but I don't think it does very well under stress. Brazing would be my first choice, with a little research you could do it yourself with MAPP gas and brass filler.The foot I'd make in wood. I wouldn't invest too much in a repair.

  2. Marilyn,If it's an area that might see repeated stress, a proper weld would probably be best, otherwise a good epoxy would likely work. For the foot, if it were me, I'd probably just shim it until it got too annoying, at which point I'd epoxy on a wooden foot.I would give it a good cleaning, but it doesn't look like it needs a new paint job. I tend to get carried away and completely tear down and rebuild everything piece of old equipment I get, though. It isn't your model, but this is one of the nicest miter saw restorations I've seen is here. Might give you a few ideas.Good luck!-Eric

  3. No, it doesn't flex, I just want to make sure it doesn't get worse. My guess is that the box fell, broke the foot and perhaps the crack developed from that or another fall. The base board has a crack perpendicular to the frame crack.Thanks for the tips. That helps a bunch!Marilyn

  4. Eric,Wow! Thanks for the link. That's quite a restoration. My welder friend is in a welding program (in school to learn how to) and is eager to help with this. So I'll probably do a "proper weld" with his help. I like the suggestion that both you and Darnell made to repair the foot.Once the welding is done, I think about how much more I want to so. A good cleaning is absolutely on the agenda. I think I saw a spider's egg sack on the underneath of the frame. :o)

  5. Cast anything is a bitch to weld and requires skills. Brazing is simpler and less hazardous to the piece. Or take it into your friends class as a challenge to the instructor…If you dont want to play with chemical strippers try a local auto body restorer. THey will have a soft-media blasting cabinet, not sure if its still walnut shells or synthetic media but softer than sandblasting so removes the finish without abrading the metal.Its a nice

  6. Eww!Bead blastin, thad be cool. I see what my welding friend has to say. Thanks for the ideas. I'm temped to repaint so that it doesn't deteriorate any further. It works well and I'm jazzed about that. The cuts I've made so far are super straight. I need to get it cleaned up and put back together so that I can get a solid base for it.

  7. Hi Marilyn,Is the table metal or wood on that? Looks like it's the all metal langdon – is that right?Cleaning: If it's greasy or oily I'd use something to clean that off first — soap and water, lacquer thinner, simple green, or if it's really nasty either Easy Off (oven cleaner) or engine cleaner from the auto parts store. I used Easy Off to clean the frame on my '56 Studebaker pickup and it cut through 60 years worth of undercoating and grease.Then I'd bead blast it, I have 220x glass beads in my cabinet and they leave a nice finish. Any surfaces that you want to have a "smooth metal" finish would need a little hand sanding with 220 and 320 grit sandpaper. For paint it perfect already.On the cracks I'd probably TIG Braze it. First the cracks need to be slightly V'd out, then lay in a bead of Silicon Bronze rod and grind/file flush. Except for the color difference it should be pretty much invisible. Cast Iron is weldable, but it's prone to cracking when it cools. You avoid that with the Silicon Bronze as you use less heat.The foot can be repaired, I'd probably cut a tab out of steel and TIG-braze it on.If you disassemble and de-grease it, and send it to me I'd be happy to bead blast and weld it. Won't take an hour start to finish.JoePS: is anyone else having trouble commenting using their wordpress login on blogger?
