Gunsmithing Homemade Chassis

[M700Shooter]

Who has built chassis systems for their rifles from scratch or extensivly modified an existing one (AICS,Mcree,etc.)? What are your experiences and thoughts.

Action manufacturer or caliber does not matter.

Re: Homemade Chassis

Offhand Scott Mcree comes to mind. Yes now hes doing it as a business but he got started the old fashioned way by having a mill and the desire to just do it.

I think it was in the rimfire section but I recall a guy on here making a AI clone trainner from an Aifsoft AI rifle. Want to say it was for a CZ action but not 100% on that.

We do it for Mauser actions. Its easy since they are flat bottomed.

There is the Eliseo tube gun that I believe started out as a "look what I made" Rem 700 chassis years back.

Re: Homemade Chassis

I have built a solid rail 7075 alloy chassis for a Mauser 98 action not fully finished yet . Still waiting on a scope rail mount from MSP .
The thing is that it does not have to look fancy to shoot real well.
As long as the flat bottom action lug cut is square across the rail and the action fits real snug or it's beddded on a thin bed of JB weld and the rail forend inline with the bore . Also the scope mount inline with the bore in the verticle plane within reason everything else is fairly non critical. It was my first attempt at an alloy chassis and it is working out good.
It all depends on what you are trying to achieve with an alloy chassis. Light weight but still rigid or super rigid with extra weight of no consequence . Some of the light weight tactical alloy chassis that I have seen are really no a great deal more rigid than a good laminated or comp fiberglass stock if at all. It's just that they are lighter for that same rigidity and wil not warp , delaminate or take in moisture etc to change POI . I am not sure how temperature variations effect them though.

Re: Homemade Chassis

I designed and in the process of producing a full chassis system with a folding stock and DBM system I started my work on early December 201 and it's going into production now but the cost is killing me and if I was at the USA where I can get anything I want I would have gone with any of the commercial products you have I know that the production of two units one for my rifle and one for a friends Remington 700 will cost me anywhere around $3000 it is going to be exactly as I want it but very expensive to make not to mention that I have a friend that makes all the cad work for me for the challenge of that and not taking any money
You can look for an early thread about it in the gunsmithing
I have an XP-100R that I saw a chassis for here in the website and if I could I would have just ordered one and get it over with it rally looks great
Good luck

Re: Homemade Chassis

Toddacguy has built 3 out of 7075, I have #1 and when he gets production going I will get one of those, the stock is 1 piece, nothing screwed together like a Mcree, accepts AICS mags, rock solid and is well thought out and comfortable, mine is heavy, the production versions will be lighter.

I also like the solid one piece setup. No matter how well things fit joints can come loose and it's one more place that could bend if it gets a wack.

Can you post some pictures as I am always interested in what others are doing to pick up new ideas.

Re: Homemade Chassis

Yes I already uploaded those images the actual stock is not made yet I changed the clip-on sight mount to a better design but the concept is here its a singel unit 60 cm in length and works with AI mags I also left enough material in the magazine housing in order to open the magazine well to CIP 0.338LM when they will be out.
I have everything ready for production but I am now downloading all measurements from a REM 700 LA for a friend and will produce them both the same time and again if someone can offer me where to get or buy the Remington 700 Inlet layout I would really appreciate it.
Thanks

Re: Homemade Chassis

GOL,

You have a 1.350-1.355 OD receiver. Its for this reason most seem to use a sort of wedge concept for the inlet of the receiver. Line contact vs trying to captivate everything.

I don't agree with that personally as I map every receiver I'm bedding, but whatever.

A revolved surface or an extrusion in your SW model should be pretty simple. I'm not a Solid Works guy so forgive my ignorance if I'm wrong on that.

You'll have to either virtual corner the lug or get really creative with a shaper/sinker EDM to get the corners right. Most just relieve with a drill first.

Hole locations:

Short action M700: .896"-.900" (22.77mm-22.86mm) from face of action to center of hole on the front screw. Rear screw is 7.393 to 7.400 (187.79mm-187.96mm) from face of action to center.

Long action M700: Front hole is the same, rear is 8.41 (213.61mm)

As for magazine well locations, your better off to sort that out yourself.

Hope this helps a bit.
