I'll make this one quick and dirty since i need to head out the door for school shortly.

My google-fu is weak, i've just spent the last hour adn a half looking for downloadable plans for any, or preferably all of the following, and have come up short.
I know that it would be easier to just buy them pre-made but i want the expereince of making them myself...

so if anyone knows where i can find plans for any of the following i'd be grateful for the info. :)

1911 Frame holdng fixture such as this one found on brownells (http://www.brownells.com/gunsmith-tools-supplies/handgun-tools/action-frame-tools/frame-tools/1911-auto-frame-holding-fixture-prod16129.aspx) or one of the less complicated/massive versions similar to what Power custom sells

Frame checkering guide (again 1911)

the firing pin removal tool for a Rem 700

there are others that have come to mind recently but they are eluding my memory at the moment.

as always thank you for you time and any and all help or info you can provide

No plans, but back in the day when I could not afford a jig, fixture, or tool from Brownells, I would use the photo and description from the catalog along with the gun itself to create a drawing for my own jig. In one case, I later bought a real MGW receiver wrench and compared it to the copy that I had made. All parts were interchangeable between the two and the external dimensions were within less than 1/16".

I think that if I figured out a way to make some kind of jig or fixture and patented it and was making money selling them I sure wouldn't publish plans so anyone with a hacksaw and a hand drill could make his own! ;)

Don't want your plans published? then tough luck getting a patent! It's part of the process, no detailed plan/blueprint showing how yours is unique and therefore the design protected, no patent. The plans are made available so that someone can search to make sure that their design does not in fact infringe on an existing patent.

Many tech firms don't patent their newest/most inovative designs because they wish to keep the workings from the eyes of their competitors for as long as possible. A patent would publish those inner workings imediately, the competitor can't directly copy the design, but they can study it to see if they can work around it.

there's little to nothing to stop a bubba with the right tools from replicating a patented design for something like a jig or fixture, for his own personal use. As long as "bubba" doesn't go out and start selling his copy to others, and therefore intrude into the commercial side of things, most patent holders aren't even going to take notice.

Brownell's set of Gunsmithing Kinks books have a lot of what you're lookin' for.
Invaluable books to have.

Man I don't know about anyone else here but I have a library with some dated materials. I borrowed a gunsmithing book from the late 30's that had plans, specs, technical drawings and materials lists for the tools you describe sans the firing pin removal tool.

Check the library. There is a bounty of useful information at those places.
