I have a 1937 Winchester 61, whose cartridge cut off is worn out. A common problem with these. Does anyone have a spare he would sell me? Thanks
Sorry, I don’t have an original spare but you can lightly peen the edge of a worn cutoff on the 61 to get it functional again.
You can normally order an aftermarket cutoff from here http://homesteadparts.com/shopcart/pid_2091.htm but they are temporarily out of stock. I am sure they will do another production run of them soon as it is a commonly replaced item.

I’ve replaced 3 cutoffs on my 1953 Model 61, the last from Jack First Gun parts, less than a year ago. Might be worth a telephone call.

I have read about peening. Is that to make the mushroom top shorter or peening on the flat side to lengthen the mushroom top? I hope this question makes sense.
I also read that you may be able to flip the cut off.
Jack First is my last call on Monday. Everyone else seems to be out of them.
Thanks

I understand your question and should have been more specific. Yes, you peen the flat side to lengthen the mushroom top. If it has been heavily used you should be able to see the spot on top that has some wear and concentrate the peening in that area. It usually does not take much.
And, yes, you can flip the cut-off over and that usually helps as well. I forgot about that trick.
Everyone has the WRF cutoffs in stock but I have never compared them to a S, L, LR cutoff. As a last resort, if they are larger than the LR it may be possible to modify one for S, L & LR by removing a little material? Never tried it myself though.

It has been my understanding that the the WRF cut off’s are similar in length, but the mushroom top is shorter. Thanks for the responses.

I received my new cartridge cut off yesterday. It was too think, so I spent the evening thinning it out on a whet stone. I almost have it to where it will fit. Now I’m wondering how whetting will affect the heat treatment of the cut off. Actually, I’m not sure the part was heat treated in the first place. No discoloration from heat. Just white metal. Does anyone know how to reheat treat or if this is necessary?
I doubt it was heat treated in the first place. If you feel heat treatment is necessary you can use Brownell’s Surface Hardening Compound as a quick and easy way to increase the surface hardness. http://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/color-case-hardening/surface-hardening-compound-prod27119.aspx
It is similar to Casenite and is a useful product to have in your gunsmith cabinet.

I appreciate it the reply. I just put it in. Seems to work fine as is.
