Al ,
I found one of these Crosman 700 Pell Masters at a junk store(Flea Market) today for $40.00 its a nice one too!!!.I will take some pictures of it tomorrow.
I do believe you said you have a way of making front sight hoods out of spring steel.This rifle is missing the original hood but it looks to be a slip on type there are two grooves(inside measurement .295 from side to side inside of grooves) cut in either side of the heavy stock below front sight blade. (sight is removeable by 2 screws).It looks like the hood was about .800 long.The outside barrel diameter is .560. So I am guessing the total diameter of the hood was probably around 5/8".
What kind of a tool did you make to roll the spring steel?How tight (small)do roll this to end up with 5/8"Dia.and how did you put the straight bends in the bottom of them after you rolled it? I have access to flat stock spring steel but how thick should it be?I remember seeing your home made hoods and was very impressed at the job you did on them.This looks to be like a simple hood to make if you know ( what your doing ha ah)and how to work with spring steel.I have never messed with this springy stuff but I know it is quite brittle when you try to make a sharp bend in it. Any help with this matter would be very helpful.

Hi Bob
Sight hoods can be tricky to make although they look a simple thing, for a start you need something like shim steel heat it up to cherry red and let it cool down naturaly, then you need to make a jig in the shape of the end profile of the sight, this is not to difficult, the shim steel then needs to be foldered round the jig etc.
I'll do a drawing of the jig you will need, depending upon the type of hood required.
Take a photo looking at the muzzel, and do you know the shape of the orignal hood?.

PS:I Just noticed the link on your post, that type of hood should be stright forward.

Bob Here's a drawing of how to fold a hood for your 700, you will have to experiment with the diameter of the bar as the finished diameter will be bigger because of the spring effect.

To start get some 1mm shim steel and soften it, roll a tube the size you want, cut the spare off about 1/8" past the flat on each side of the former, clamp in the vise where marked and tap down the lips.

Finish off with a file, polish then heat to a light blue and quench in light oil or soulible oil if you have some, this should put the spring back, you may need to experment with a bit of scrap material first.



Have Fun

Al

Thanks Al,
As soon as I get her back in cosmetic beauty I will make the hood.
Its not beat up just neglected,light rust on metal,stock has a few surface scratches but not into the wood.I think it can be restored to its original look with a little TLC.

Thanks again!!
