Re: '66 Sunbeam Minx Project - F20C/6sp/4-link/Discs...
Another thing that bugged me was the tight clearance between the lower arms and the xmember at one point when the alignment bolts were set to the inboard position:
Solution: ![]() ![]() ![]() The S2000 xmember sections I used were lopped off behind the rear arm mount holes in order to fit the Minx because the Minx frame rails drop down just aft of the arms. So it has been the plan, and is finally implemented, to box the ends for restored strength: ![]() Ready for powdercoat: ![]() |

Super progress Frizzle! Your welds and metal work set the bar so high.....gives me something to shoot for

Re: '66 Sunbeam Minx Project - F20C/6sp/4-link/Discs...
Awesome work Frizz!
I've been lurking and admiring your builds for a while now. There is one aspect of this build that concerns me, and that is the sway bar mod. The sway bar is designed to absorb torsional forces and distribute them evenly down the length of the bar. When you cut and welded that bar to shorten it, you increased the stiffness (by decreasing the length) and I suspect that there is also a "stiff spot" in the bar at the weld point now.... So torsional forces will not be distributed evenly anymore. I don't know what the ultimate effect will be, but I suspect that you might end up with cracks at the welded area, and/or the bar will behave like a much thicker diameter one and may upset the handling. I am fairly certain that there are companies out there who can custom-bend a sway bar to match the shape you need using your modified sway bar as the template. Or you could convert to a 3-piece sway bar setup with a center torsion bar and two splined end links. That style would allow you to swap out the center bar (thicker or thinner) to fine tune the handling later on. Or change the lengths of the end links to soften or stiffen things up. Just a few thoughts over my morning coffee.... The fabrication is amazing! -G Posted via Mobile Device Posted via Mobile Device

The formulas for calculating sway bar stiffness are on the interwebs but as you mentioned, it's largely an academic argument....the test drive will tell you if it's too stiff or not. I don't recall if this bar is on the front or rear. If it's a rear bar, you will probably have a ton of oversteer, if it's a front bar you'll see understeer. With as much power as you are adding to that chassis, it might be good to set the car up for some understeer and when you want to kick the tail out with oversteer....just call for it with the throttle! ![]() Good stuff...

Re: '66 Sunbeam Minx Project - F20C/6sp/4-link/Discs...
Nice! Where do you find the most durable flap discs and wire wheels? I've been getting the wheels from HF and they are super cheap on sale and seem to last a decent time compared to a dewalt one I had but don't know how to compare....
I've been getting the flap discs from Lehigh valley adhesives for fairly cheap but not happy with how they last....

Re: '66 Sunbeam Minx Project - F20C/6sp/4-link/Discs...
Just wondering if heating the entire bar would fix the grain in the heat affected zone of the weld. Not a full heat treat, which would probably harden it more, but maybe a soak at like 5-600 F. I'm not a metalurgist, but work with ASME steel fab shops, and I stayed at a Holiday Inn Express once.

Re: '66 Sunbeam Minx Project - F20C/6sp/4-link/Discs...
Just started buying some of the consumables at HF. The cut-off wheels work fine. Grind disc seem ok. Flaps wear fast. Can't remember if I picked up a wire wheel there or not. Prior to that I was getting them from various places; Airgas, HD/Lowes, Fastenal, local metal shop.
It's the front bar that I've shortened. So yes, understeer will be the result of too much front anti-roll. I do have a rear bar I plan on running so that will help. Ultimately I'd like to build a front bar with blade arms: ![]() ![]() HG, I'll have to googlify that! |

Could also reduce the diameter of the bar, a good machinist should be able to figure a way to mount it in the chuck.

The blade ends provide instant adjustability. By turning them their flex rate changes which provides the equivalent of a thicker or thinner bar.

Re: '66 Sunbeam Minx Project - F20C/6sp/4-link/Discs...
I'll come out right and ask for more info on the blade arms, what are the stepped levels about, how do you dial them in firmer/softer? Cool stuff as usual and thanks in advance.

Re: '66 Sunbeam Minx Project - F20C/6sp/4-link/Discs...
Stepped ends are machined to fit these:
![]() The blades work by clocking them between horizontal and vertical, or any degree between. So imagine them set horizontal. They will flex more than when set vertical. When they flex they absorb some of the twist (twist is induced by body roll), thus reducing the total torsional resistance of the entire assembly (like having a lighter bar). When they are set vertical they flex less and more of the twist is transferred to the bar/shaft. Thus increasing the total torsional resistance of the entire assembly (like having a heavier bar). Hope that helps. Last edited by Frizzle Fry; 09-30-2011 at 04:10 PM. |
