Forearm comes off in hand when fired
 

I have a DH that when I shot doves with it (lots of shots) the forend detaches from the barrels. If one just barely pulls the lever, it comes off easily. But not firing it is on there and does not fall off.

Looking for the repair (hope it is easy). No, I don't want to run Scotch tape around the barrels and forend! Thanks.

Sounds like your forend loop is messed up and the forend toggle is not engaging it enough.

Take your forend apart and snap the forend iron back on the barrels by itself and see how snug the locking toggle is .

Tough to do on a DH as everything depends on the wood separating the opening lever from the forend iron. The lever only takes the slightest pull on it to get the forend off. Trying to figure where the problem is; the lever?, the flat steel lever spring?, the toggle that engages the barrel lug?, the barrel lug?

The forend locks well on the barrels and lug. You can't pull it off. But when shot the recoil causes it to disengage.

The forend loop (forend lug on the barrels) probably needs material added and then dressed down for a perfect fit, forcing the forend rearward a few thousandths.

The lever spring only returns the lever after being lifted. You can actually remove the lever assembly and put the forend back on the barrels and manually push the toggle under the lug. If it's not snug, then you could add material under the lug to tighten toggle contact. I've seemed the lug peened to achieve this. Lol

Dont peen any part of a Parker unless you have a desire to rapidly diminish its value.

Oh for sure, NEVER peen! Best to add then remove...

HI. I have a DH 2 barrel set doing the same thing - forearm comes off when shot. Who would you recommend for the repair? I have had Turnbull do some work on an LC Smith before with good results. Funny thing is the forearm comes off easily on the 16 gauge barrels, but is super tight on the 20 gauge barrels.

You likely have a forend lug issue with the 16g. barrels. Either due to wear or improper re-working.
If you want to have Turnbull's guys do the repair, you can't go wrong.

The travel of he toggle is limited by the latch, so pushing it under the lug may not be the position it would be if the latch were in place. The lobe of the toggle may be worn. If I recall, Brian has replacement toggles.

On my DH the forend is on there as tight as it can be. One cannot pull it off once on. However, the slightest pull on the forend lever releases it, so Edgar is correct. That is why taking the wood off and just putting the forend iron on probably won't tell me anything in my opinion.

The inertia of the recoil moves the lever enough to disconnect the forend after firing.

Just a suggestion Jerry. I would try putting a shim between the toggle leaver and the spring to stiffen the spring and increase pressure on the toggle. If that works than your spring is getting weak.

Jerry, with the forend in place on the barrels can you move the forend rearward even a few thousandths? Is there any front to rear travel at all?

Amen !

Dean,

As we say in the South, "as tight as a tick." When I pull the fore end lever a few hundreds of an inch, it comes off. But putting it on one can feel it securely lock in place, as the lever moves out as the fore end tumbler, part 35, tumbles into place under the barrel lug.

Hmm... Presuming those barrels are tight and on face it makes one wonder how the latching of the forend could have gotten so out of adjestment as all it can do to become out of adjustment is to wear out of adjustment.

I fit a set of orphaned barrels to one of my Parkers and the forend wouldn't even stay on at all. My brother-in-law is a Navy certified welder of turbine engine parts and he welded some material to the rear face of the forend lug which I dressed down to cause the rear face of the forend iron to fit snugly against the knuckle face of the frame. And he welded some material to the hook at the front of the lug, which I also dressed to a perfect fit so that the latch worked flawlessly. I know this isn't in everybody's budget and I'm glad I didn't have to pay to have it done. There are probably shortcuts to the route I took and I hope you are able to finally get yours working properly.

Best, Dean
