Scot Laughlin's Custom All Weather 2260

2260 with short crosman receiver atop a mini riser made from aluminum tube. Barrel is a 2200 soda straw
tensioned inside a titanium golf club shaft. Three screw mod to the trigger, bulk co2, SSP 250 rear cocking
striker assembly. Factory stock, reshaped, bedliner finish and stick on cheek piece. The idea was a weather
resistant light hunter for rainy days.
I've got a Cothran stainless receiver and gas tube waiting for me to get back to this one.

Can a bigger screw be used to mount the breach...

...of a 13xx or 22xx gun? You know, the little one in front of or under the bolt?
I have a 2200 that I'm contemplating using the pump tube and parts for my 1377 rifle conversion. The only #4 taps I see locally are for coarse threads. The breach screws are fine thread aren't they? Has anyone tried a #6 screw?

Thanks!
Andy

I have used a #5, after reshaping the head

I would not use the commonly available 6X32 the thread is to coarse, there just isn't enough "meat" in the tube for a larger screw . Smaller taps and screws are available through industrial suppliers and hobby shops they are just not commonly available due to the small volume of sales,
If you need a larger screw due to a damaged thread I would reccomend a 5X44 or a 5X40 these are available through McMaster Carr at:
http://www.mcmaster.com

They also carry a 6X48 screw but I'm not sure if the head of this screw can be modified enough to fit the guns in question without modifying the breech itself which is something I would not want to attempt.

Andy You've

been involved with these 22xx platform guns for a while now, so my advise would be to bite the bullet and buy a 4/48 tap from one of the machine equipment suppliers, as in all probability you'll need it more than once. You can re-drill and tap the tube for a #5 or #6-48 but that tap isn't east to find either and going to a courser tap won't get many threads in a 1/16" thick tube wall. And after that you will have to try to keep the new larger screw head size from being in the way. If you have a problem finding a 4-48 tap, drop me a note and I'll give you a supplier.

I have a extra 4-48 tap....

August 6 2012, 5:25 PM 

you can use, then pass it around to those that might need it.

This comes up several times a year on here. Maybe we all can use it as a "passaround loaner" tap. It's quite delicate, but it's the best one available and easily cuts the hardest Stainless Steels.

Let me know.
