teraflex makes their sliders out of aluminum.
Its more a cost and durability thing.In an attempt to get some technical discussions started and a topic on Jeeps I have a question?
I am all about reducing weight on my Jeep and most of the armor that you buy for Jeeps is really heavy steel. These jeeps have a hard enough time pulling their own weight without having 1000lbs of additional weight added in bumpers, shids, rockers, etc.
I have often wondered why there aren't more light weight materials used for some of these items.
I understand that aluminum is not as strong as steel and will not take the abuse steel will (i.e. skid plates).
With that being said, I would think that items such as bumpers could be made from aluminum if steel inserts were used for specific parts such as steel winch plates, and steel inserts that would be used as tow points. IF these pieces were reinforced and attached to the frame, would they be strong enough?
There are obvious areas of concern such as tire carrier mounting, shackle mounts, winch, etc.. I would think these could be worked around with the right design and the weight saved could be in the hundreds of pounds.
Unfortunately items such as skids would probably not be a candidate, since the skids on JK's span such a large area and would not withstand the forces applied if they were aluminum.
But rockers could theoretically be made from aluminum with replaceable steel skins that could take the abuse and when the steel skin was beat up bad enough, take it off and replace it?
This may all be pipe dream based on the cost of engineering and producing something out of aluminum (i.e. the cost would likely be very high), but like I said at the beginning, I just wanted to talk Jeeps and this is something I have been kicking around in my head for years....
The only problem is paint does not stick very well to aluminum unless a strict process is followed. I do not know that process myself, I just know one exists and certain paints need to be used. I have heard of the Teraflex ones having the paint peel off.teraflex makes their sliders out of aluminum.
I do not have aluminum skids but my sliders have aluminium skins. At first I was worried they would just bend to easy with a direct hit. I ended up taking a direct hit and they actually held up pretty well, I was surprised. They are gouged a little but it was mostly only the clear coat on them that scraped off. YOu can barley see it in this picture but it is towards the rear of the slider on the aluminium above where the scrapes are on the steelTeej said:I've SEEN Al skids, and, they gouged and were damaged like crazy...so I was not impressed...but, I don't know what grade, etc, of Al was used, etc.
T-6 alloy, etc...is pretty good stuff...if anyone used it for skids, they should pipe up
from Pirate4x4 said:The boat side skids are made from .200" 7075 aluminum.
Geargoyle told me a neat trick on how to bend the aluminum.
Draw a line with a Sharpie where the bend is to take place. Then, with a rose bud, heat the aluminum on either side of the line. When the line starts to become faint, make the bend.
YAh, take a look at that thread I linked above. They have a short discusuion about it. Looks like there was some comments that the Nylon was supposed to be nearly as strong. That may be what your cutting board is made of. They were using 3/4 inchPlastic huh? Wonder how much plastic material like the stuff they use for cutting boards would cost. I have a white cuttin board that is about quarter inch thick and that stuff is indestructable even after many hours of chopping food on it and I can see that it would be slick enough and light weight.....interesting consideration
I couldn't agree more. I think so much stuff for the Jeep come from the garage welder. Like you said, it is just easier to weld up a bunch of plate.There are all kinds of ways to keep the weight down on these things, its just easier to build it with heavy steel and call it "hardcore"
It is kinda funny to me...I come from more of a auto racing back ground, I had an XJ to play in but it was not my main focus. Anyway, everything was about saving weight. I mean, even switches and knobs where made out of light weight material or drilled out.The amount that I see aluminum used for other uses and other motorsports without prices being outrageous I don't see why it can't be done here.
Even if you use KerryP's wheel example. Each wheel is not outrageously expensive. That same amount of material could be cast/forged or assembled to make bumpers, etc.
Once problem I see is that there are so many other things made for Jeeps from steel that have no real reason for it. (like CB racks, light tabs, etc )
