Need help with pumper pump link

[flytie]

Background info: picked up a Sharp Victory. While pumping, the pump link lever cracked close to pump Rod connection pin. Had it tig welded. Upon pumping again, it bent slightly vertically. I'm guessing the pump link may have been heat treated and the tig welding weakened it.

Since the tig weld metal is different from the rest I don't know if it can be re-heat treated. If not who can make me a new one? I would need it re-pinned to the lever assembly.

I really want to get this classic up and running again. Any help appreciated.

might be the same length as an innova or ace
if you measure the hole centers I'll check it against an innova and an ace,i haven't managed to acquire a victory yet

Find a local metal shop and have them use the one you have as a template to make a new one.

Yes I can have one made to match; however, what to make it out of? What about a new pin and re-attaching link to the main lever?

Took it to a local machine shop and the guy wanted no part of it. Said to find a gunsmith.

Tim at MAC1 said to find help here.

Measure it and compare numbers with other similar, available parts. Maybe a 392 or vintage Ben/Dan link will be close enough to just re-drill/bush one or both holes and round off the corners.

The webly rebel is a knockoff of the innova/ace. Try contacting webly. Measure the lever link center to center, at the pin holes.

Ace, Innova, and Victory link lever holes appear to be same distance.

The problem is the designs are different. The Victory link has a curve on the end that attaches to the pump Rod. There are NO holes in the air tube. The pump Rod length is adjusted by pushing the pump Rod assembly out the end of the air tube just enough so the link pin hole clears and the pin can be pushed out.

To make the Innova/Ace link lever work, I would have to alter the air tube by drilling two holes near the muzzle end in order to add/remove the link pin and pump Rod assembly. The originality would be altered therefore making this a "last resort" so to speak.

If I had the link made out of tool steel do you think it would be strong enough without having it heat treated?

[longhunter]

No. Tool steel is a higher grade of steel. Less impurities, and different types of alloys added. It would still need to be heat treated,to be strong enough to withstand the stress of pumping.
Actually, the lever link is most likely made of spring steel.

[flytie]

The way I understand things is gauge plate = tool steel

There has to be a certain carbon content for steel to be heat treated. Tool steel has the required percentage. Standard run of the mill steel does not. Don't know about spring steel?

Someone told me a simple test to see it steel has been heat treated is to run a small file across it. If treated, no mark will be made.

I performed this test on Innova/Ace link and Victory. A slight mark was made on ALL pieces. Don't know if I did it correctly. Not sure what to make of this?

[longhunter]

You run the corner of the edge of the file lightly across the steel. Not the teeth. It still may make a very fine mark,  even though it's been hardened. A lot of lever links are only hardened at the ends. The rest is whatever it is. Not the right way to go,  but that's what it is.  You should be fine using plate, just so long as it's hard enough that it can't be drilled with a HSS bit. It should require the use of a carbide bit,  or end mill.

you can use gauge plate and harden and temper or use a good quality cold rolled steel and case harden with kassenite or similar

If you can find any. They quit marketing kassenite, about a year ago. Don't know of a substitute.

just bought some last week called beta 1 of ebay

Let me know how it compares to the kassenite.

[anuthabubba]

Maybe could use an old saw blade to make a link from?

 You can get surface hardening compound from Brownells Gunsmith Supply. It is a bit expensive at $22. for one pound jar. Many metal working websites also sell it, but most are larger size than you really need.  Kasenit came in a small can last I bought some, but must be gone off market now.

Thanks for all the help guys!

I found a local "smith" who is fixing her up for me.

glad to hear you're getting it taken care of. can't wait to see the end result.
