unless you have the capability to build one for each side(casting one for each side,and machining them to correct tolerances...) why would you even try?...
I wouldn't even consider it...but that wasn't Bugroadsters question. I just hate those glib little answers he received. A guy with basic machine shop tools and skills could easily make a set of spindles...from steel billet...no casting involved. Would it be cost effective? Absolutely not! Spindles are cheap as dirt compared to the effort a Rodder would have to expend to make them! Could it be safe? Done by someone who has skills and a lot of time to waste...Absolutely.
Yes,I have made my own spindles,from scratch, for IRS and IFS. Made two complete sets,and the fixtures to make more. Along with upper and lower a-arms,tie rods,steering arms, trailing arms,push rods,rocker arms,etc. Also made billet Aluminum calipers,for Drisk Brakes. (not a spelling error) Lots of work,and time,even when you have all the equipment.
Most higher cl***es of circle track racing have fabricated spindles, so I don't see why it would be a problem building a set.
We put a guy on the moon a few years back - c'mon guys, you're killing me with this... "Improvise, adapt and overcome." - U.S. Marine Corps mantra ------------------------------------------------------------------- (These two were built by Max Fish at Bio Kustumz - They arn't for a Dropped Axle, but you get the idea... Just take your time.)
The strange looking ones on the bike are called parameter brakes Drisk brakes are a cross between a drum and disc brake. We used a convention cast iron brake drum,machined the od smooth,then i made a custom caliper from a block of 6061 T6, that squeezed specially modified brake pads against the OD and ID. We copied the idea,from M***aratti,who used it back in the '50s. Someone else probably used it earlier. The idea is the get more leverage than a regular disc. And better cooling than a regular drum. Actually,we knew drums were no good,decent racing disc brakes were "expensive",so for the price of a few blocks of Aluminum,I made calipers,and machined down some drums. We were the first ones to use Drisk brakes on a Formula 4, along with push rod suspension,inboard sway bars,adjustable brake bias,removable steering wheel,right side shifter,etc. Just about everything on that car was custom made,or heavily modified. Won the Best Engineered award,the first year it raced. The club never had a Best Engineered award before, so they created one. I understand,someone was building and selling copies, several years later.
I have an old magazine, Circle Track or something similar I think, that has mention of of Drisk brakes. Combination of drum and disk, instead of a disk, its a drum surfaced inside AND out, and a caliper to squeze the pads.
I am very familiar with this brake system. I helped with the design and build of the drisk system that you are talking about, back in the late 80s,early 90s, in Wiarton On. Canada... We also designed a quick release Rim nut for NASCAR.
