I just received a pack of springs from Grainger, 1NCH3, to use for the firing pin return springs. I clipped one full coil off to match the length of the sacked out rusty original. It works quite nicely with no binding and a positive pin withdrawal! The large coil spring for the lifter itself is decent, but pitted. I need to shop around some more to see if I can come up with a replacement. Cheers!

I just received a package of part number 1NCN9 springs from Grainger. I clipped a few coils on one and it works splendidly for the lifter plunger.

I have replaced one of the firing pins from my 1879 Parker Underlifter with a pin made by Dave Purnell. My springs were very rusty and I at the time thought about replacing them. I am glad to know where to find them. What year is you underlifter?

Thanks'

My two 'Lifters' are 1877 (12 gauge) and 1879 vintage (10 gauge).

Let us know how they worked, Pat. I was very pleased with my results. The original springs had the ends twisted into a 'pad' of sorts. The lack of the 'pad' on the Grainger springs was of no consequence. Cheers!

Pat, did you try out the new springs from Grainger's? How did they work? Did you have to clip a lot of coils?

I am embarrassed to say that they have been received, but not used yet. I have taken the firing pins out sometime ago and know what the original springs look like with the expanded pad and like you, know that the new springs will work OK. You have motivated me to work on them. I will post my results. Thanks for the information.

Mark, I am running into some interesting problems, First I talked to Austin about springs in guns with solid head plungers, seems my guns below 50,000 ser# have no springs,above 50000 they do. Austins guns seem to be the same. Now that said I tried to put a spring in a 36000 # gun and even cutting down to one coil, I did not have enough travel in the firing pin to engage the primer in the shell, Could it be that some of the later solid head plungers were longer than the early ones? I also checked both firing pins Identical lenght, so I ruled out broken or chipped pin. Maybe some of the hammer guys can measure the pins in said ser# range. I will ckeck also.

Just to let you know I checked for any broken spring residue inthe gun

Gary, my 2 Lifters (10250 and 15728) have the stepped/crooked firing pins held in place with the threaded bushing. The guns had springs that were not real stout. They seemed to provide just enough tension to withdraw the firing pin after the hammer rebounded. The springs all had a little 'pad' on each end where someone used needle nosed pliers and made each end coil smaller than the rest of the spring. The large lifter plunger spring in both guns had the same little twisted pad, too.

Start a new topic and you should get some answers

Gary, I believe the post 50,000 serial number guns had the frames machined deeper to accept the springs.
