Hi all,
New to this forum, always find these things dang useful! Anyway, my Dad has a model 241 Speedmaster and the cartridge guide pin went missing. This is the little spring-loaded plunger that keeps the cartridge from falling out the ejection port before the bolt can chamber it. It's located on the left hand side of the receiver under a set screw. I've not been able to locate one to buy so I'm going to try and make one. Anyone know what the size and thread pitch is on the cap screw? kinda looks like #10/48tpi or something.
Thanks,
Dan Oltmans

Here is some advice,
TAKE THE GUN TO A GUNSMITH AND HAVE IT REPAIRED.
If you do not have a gunsmith that will do the work for you, you can send it to Grice Gunshop in Clearfield Pa. Or Mahoning Valley Milling in Punxsutawney PA. and one of their gunsmiths will be more than happy to repair it for you. They might even have the part you need on stock!
You obviously do not know what you are doing, or else you would know that you cannot just guess what thread something is.
There are millions of different threads in this world. It could be metric, it could be English, it could be SAE, you just never know until you inspect it.
I know that you asked what thread is it, but you have to remember - you have the gun, we don't. There could be models where they changed the design of a part from one year to the next.
So take it to a qualified gunsmith and have it repaired.
Threads per a inch is measured with a thread pitch gauge.
That is where a gunsmith and a qualified machinist comes in.

I don't think your question is unreasonable. If you were guessing what caliber a rifle was and tried different ammo to see what worked, I might question your judgement. I rather doubt your M/241 uses anything metric... If you do err on the threads on a cartridge guide pin, it isn't like the rifle becomes dangerous.
Doesn't Brownells have a tech person to help with questions like yours???

threads, man
Wow, thought it was a simple question but I guess you never can tell. The the first poster, probably should let you know a little back gound on myself: I have been mechanic for 6 years on Boeing AH-64A model and Longbow Apache, CH-47D Chinook, UH-60A/L Blackhawk, OH-58D Kiowa Warrior and TH-67 Creek helicopters. So I think that perhaps I DO know what I'm doing when it comes to simple things like screws and all. 
Besides, I've been working on my own guns for years and I know my limitations. like the one poster said, I'm not messing with anything dangerous anyway. Thanks for the advice though. I wish it was as simple as just finding one of these pieces but after two years I've had ZERO luck locating this part and would kind of like to get the gun back in action. Had an easier time rebuilding my 3rd generation Winchester 1890 WRF!
To the the second poster, the thread size I was guessing on was SAE #8 or 10-48 not M10, that would be WAY too big. My winchester has some odd size like 10-35 or something and its from the same time frame (early 40's) thats why I asked if anyone knew. Good idea on calling Brownells, I'll try that on Monday.
I'll post pictures of whatever i end up doing on here when (IF) I make anything that works!
Later,
Dan
