Folks

I have 4 of the De Haas single shot books, but one I have never been able to lay my hands on from down here is the Gunsmithing one.

I understand it has an article on modifying the rolling block action so it is actuated by a lever rather than the thumb piece.

Is this the same as the "Carlos Gove" lever ??

I would love some more info on how these work and if possible a scanned copy of the De Haas article.

Cheers - Foster

Foster,

I don't have that book, so I can't tell if it is the same as the same as the "Carlos Gove" lever. However, the website below lists the de haas book forsale. http://www.gunbooksales.com/sshot.htm

Never used this company so I don't know if they are willing to send books to new zealand.

Thanks for that link, M.H.. Now that it's back in print, I'll be able to geta copy.

T.: I know of two lever conversions for the RB. The Gove connects an underlever to the block with a curved link. The other is a straight forward side hammer, at the end of the breech pin (which obviously must be splined, or the like). I know the site of Lone Star Rifles has pictures of the side lever.

Tentman, I have the book in question. DeHaas' method is not the same as the method Carlos Gove used, but rather a method he (DeHaas) worked out on his own. Personally, I prefer the look and function of rollers converted to side-lever operation...I think it's a much more elegant solution (though to a non-existent problem )

Side levers are not as good for extraction of long cartridges.

Hmmmm, now that is not obvious. Why would the side lever create a problem with long cartridges? From the pictures, it clearly has better leverage. It might, though, reduce the "snap" of the breech on opening, making it more unlikely the case will eject, esp. a long one.

There were at least three lever conversions done on the Roller and I think all are attributable to Mr. Gove. There is the simple side lever, which actually works quite well. I did this conversion and used the rifle extensively. The second is a hybrid side/ underlever that attached to the hammer pin like a side lever. It extends downward from the pin and curves around the bottom of the action to the middle, where it bends back parallel to the action and follows the outside contour of the triggerguard. Sort of like a Ruger #1 lever does.

The third lever modification is a true underlever, and this is the type that is detailed in DeHass's book. Howsomever, in the original Gove modification the movement of the lever cock the hammer as well as opening the breech. The DeHass design required the hammer to be cocked before the lever could operate the breech block, as do the side lever modifications.

asdf, my comment IS confusing, of course a sidelever on a roller gives more leverage than the little protrusion on the breechblock. But it is much inferior to an underlever and that is what I should have clarified.
