Skil drill press return spring

Skil drill press return spring repair


The return spring broke on our new Skil drill press.

Its been almost a year since we got it, and today was the first problem in all that time.

I tried making what was left of the spring work by attempting to bend back the new bitter end so it could slide into the slot on the shaft, but the metal only bent a small amount.

A quick call into Skil headquarters put me in touch with a nice tech by the name of Sandy. He offered to send us out a new return spring for free. I'm guesing the spring comes wound in the above metal holder, otherwise it's going to be a bear to wind by hand.

I know you have a new spring assembly coming, but just for reference for future projects/repairs it is no big deal to bend the end of this type of flat spring. If the bent tab needs to be hypothetically 3/8" long just submerge the spring in water with an extra 1/4" or 5/16" sitting proud of the water and then spot heat to pull the temper to make it soft enough to bend.One could heat to a straw color and then quench and test the bendability, and repeat all the way down to a purple or black color if necessary to achieve the desired softness. If you make sure you pull the temper a little bit past the spot you intend to bend you won't have to worry about snapping the spring when you bend it.Bob.

Steel alloys for mainsprings are usually hardened after being rolled into their desired shape. In that hardened state they're difficult to bend without breaking.

It's nice to see companies that stand behind their products and will ship parts at no cost to the consumers. I like to make my purchases from companies like that.

bob --- Thanks so much for that description! That would have helped Mark a lot when he was struggling with the broken spring....

Roland --- That seems to match up with Mark's experience (and with bob's tips).

Heath --- Yep, I guess that's a vote for Skil, even if the spring did break relatively quickly.
