    delrin will work is 90% the way to spherical bearings so why not do it right

    cost.

    For approx $25.00 and a (fairly) short time at the lathe, I crank out multiple bushings.
    I start with rear toe bushings, and then curiosity starts hitting and for $50.00, and some more time at the lathe, I build bushing for the front a-arms for proof of concept.
    Thinking the front because there will be minimal heat, and I can evaluate what it does to the ride.
    if the ride is acceptable, I crank out the ones for the rear, may use a different material here because of heat.

    Slippery slope case, for about 10% of the cost of the spherical bearings, and some time at the lathe, I get 90% of the advantage of spherical bearings.

    WOW, if you can make all 20 Delrin bushing and the sleeves to go over the bolts for $50 i will take 3 sets for sure

    I already have the sleeves. The Poly bushings I bought from you came with a set
    bought 1.25" diameter 36" delrin rod, figure 18 bushings (1.5"*18=27" with 9" of wast), for $29.00

    I need 10 bushings, 8 for the front, 2 for the rear toe links, and I have proof of concept.
    If the ride is acceptable, I can research doing the rear, (I am a little nervous about temps for Delrin in the rear a-arms).

    There are 20 bushings total 8 in the front and 10 in the rear

    The operating temp of Delrin is 247 F so i am pretty sure you are not going to have a problem with the heat. That is not the melting temp it does not melt till 348 F

    You do need shoulders on the bushings if not the a arms will slide forward and aft.

    Do not forget to use bushing grease or the will squeak like a squeaky toy all the time, and you will have to repeat the process about once a year

    Here is the drawing to make it a little easier since i have already done the research

    Drawing in both SAE and MM since it is just a click of a button. I can work in both but when i an machining i can relate to SAE easier

    Very nice. Thank you!

    Saw your post on Facebook.

    how much for just the install tool?

    assuming it's (way over simplified) a cup, plunger and a bolt/all thread sort of tool also good for extracting these little burgers?
