Default Making my own shock towers

So I have a 25x52 rotary engraving table. Basically a small cnc machine. I own a losi xxx-4g+ and decided I am going to machine my own front and rear shock towers.

I can buy carbon fiber but it's pretty pricy. Does anyone have any experience with general plastic. In other words what is the stock material used in the xxx-4?

I was thingking about 3/16 abs plastic. Or maybee 3/16 derlin

anybody have any ideas?

ABS is Tamiya stuff. Very bendy which is good for toys, not so good for race cars.

I've seen a few delrin aftermarket parts around. Apparently it's fantastic for RC's

I don't know if companies like losi have special mixes blended for them or what. But I can get a 24x48 sheet of abs in 3/16 for 33 bucks and I can yield 115 shock towers

I just was looking for something not as pricy as carbon or graphite just a good durable plastic.

I currently copying the xxx-4 front shock tower in my cad program right now. gonna make front and rears and maybee some battery straps who knows

I guess I could just get some 6061 aluminum and machine those.

You could check out some Garolite G10. Its a fiberglass resin stuff, nearly as stiff as carbon fiber at ~1/10th the price. Same stuff they cut/make most circuit boards out of.

Hmm just looked at it. Never heard of it. wonder how brittle it would be?

Not trying to re-invent the wheel just wanna make some parts to save some money and maybee sell to other xxx-4 users.

Delrin is some tuff stuff, and its easily machined. I would go with that for plastic. Aluminum could be heavy so i would try to find some cheap carbon fiber

From what I have read the tensile strength is low compared to carbon fiber. I wonder how heavy a piece of 1/8 aluminum vs 3/16 derlin would be.

Well for me it's pretty easy to do. I have a 100watt laser as well as the cnc machine. I noticed that this is a part that will break alot on the xxx-4. I saw that they get 18 bucks for a carbon fiber shock tower and 8 for the standard. That's pretty pricy. I just traces a shock tower and scanned it into my cad program now I just need to re-create it and cut it out.

So im doing it for fun yes, to save a little money yes and maybee sell some yes.

Sounds like a plan to me

I worked at Tap Plastics for several years, Delrin or Nylon will be your best bet outside a fiberglass material.

Delrin is a little stiffer, Nylon allows a little more flex and resistance to direct impact/cracking.

both will be great materials though.

I had Delrin arms for the front of my XXX-4 G+ when I had it and they held up great. G-10 is good from what I've heard too but I've never used it.

The derlin looked appealing to me. I know guys were doubling up the xxx-4 shock towers. They are 1/8 so I was thinking about going with a happy medium and getting 3/16 what do you think?

i hink you should send a set to me! For testing and quality control of course

But seriously, if you can make them cheap and consistent quality (i'm sure the CNC will take care of that), there may be a bit of a market for them
