Default Fixing Junk

I have an old Snap On 3/8" air ratchet, Far 72 that the rep said is obsolete with no parts available. There are parts for the later 72 series but they won't interchange. The socket anvil has sheared off. I built it up with the mig and machined it to the correct od. I plan to mill the flats. I have two questions, has anyone installed a homemade ball and socket retainer and would it do any good to heat and oil harden the piece? I have another ratchet in mind but like to mess with things I should throw away. Thank You for any replies. CK

I have a FAR70 that has to be older than your 72. It keeps on chuggin away.
Tinker with it for a while but remember you often can get something new for as cheap as $20 at Harbor Fright.

If it is a Snap- On I find it hard to believe that parts can not be gotten for, I have 1/2" drive Blue Point which is the for runner of Snap- On and parts could be had for it. I bought an old 3/8" drive Snap-On off ebay 10 years ago and it was used but still work good. Put some pressure on your dealer.

Sounds like you know what you are doing, wonder how much progress on your projects you would make if you did not have to take time off to repair your old tools.

Just saying, spent a many a day repairing a tool or machine to the point I never got done what I planed to get done that day...

I don't think welding will hold up, tool steel is usually pretty hard through and through, case hardening will stop wear but won't make it any stronger. For a retaining ball you could try dissecting an old extension, use a Dremel cutoff wheel to whittle away the outside, saving the ball, spring, and retainer.

Sometimes making the tool needed to repair the tool you need for the project is the project for the day.

Why go through all that trouble when eBay is LOADED with used FAR72 ratchets you can buy for either parts or to use, and CHEAP. Ive had an FAR72 knuckle buster for almost 25 years and have put some serious hand leverage on it and never had to warranty anything on it except the plastic trigger button when I dropped it. Sounds like you should have used a 1/2" ratchet that time to shear the anvil on one of those.

If you were talking to 1 of the guys on the tool truck and got that reply, go thru the website or the distribution warehouse. I had a 1/2 drive ratchet,a big long 1,that was worn out. The truck man said, he would allow me half price towards a new 1. I took to the distribution warehouse and laid it on the counter and walked out with a new 1. Turns out mine was ww2 surplus.

Well a little update on the air ratchet I repaired. As for the retainer, I cut a groove at the end of the of the socket mandrel like the old blue point ratchets and used one coil off a small spring. Worked like a charm. Got it all back together put a bolt in the vice and (tested) the weld. Held up great. The only real problem is that I should have taken some good advice on this thread as the ratchet gear is about worn out, you have to hold it just right for it to drive the socket with any usable force. Bought a new import one off ebay, Twenty bucks. Live and learn. CK
