Much warmer 70s and sunny every day. Got a little windy one day but other then that the best weather we have ever had.

Those are great pics, nice job. The wrap looks incredible also.

Anyone else, I'd say that was an accident. What were you doing? It looks pretty flat

His lift broke and he needed to lube the chassis.

Been a while since I have built anything for my roxor but today I started somthing I’ve been thinking about since I started moving towards aluminum armor.

I went and picked up a 1x3 of solid aluminum bar expecting to break the bank. To my surprise aluminum was cheaper then steel. A 12 foot bar was only $140!

Now what could I be up too?

I got a set of aluminum rocker guards from Cecco Racing and, while they are pretty stout by them selves, I knew I’d want a little more strength for the abuse my roxor seems to endure. The tube sliders I made originally are dented pretty bad and that’s with .250 wall DOM. So if these things are going to last some serious strength was going to need to be added.

See where I’m going with this?

After cutting the old sliders off I realized how important they were not just as a slider but also a step. With the door bars on my cage the door is just about useless for anything other then a access panel to get under the dash.
A step is pretty nice to have for climbing in and out on club trail days but would get caught up on everything on hard wheeling days.

After sitting back and staring at it for a while I came up with an idea to add a removable step into the thick plate I was adding to the side of the Cecco pans.

After an hour of chips flying all over the shop, here is what I came up with.

The step should be able to take a far amount of abuse but it can also be removed completely. A couple counter sunk bolts and some skateboard grip tape and I’ll be set.

Now I need to start brainstorming what to do underneath.

@Max A. : what kind of structural reinforcement do you have behind the aluminum to connect it to the frame?

Glad to see your latest build.

I’ve got some ideas. It definitely needs to take a beating without doing any damage to the body.

What grade aluminum bar did you get? Hope its at least 6061 because 5052 is really soft. 2024 will hold up better and 7075 is just as hard as steel but costs an arm and a leg and corrodes faster than the fore mentioned grades. Make them bolts big ones! Where you drive and how you drive, those ARE GOING to take a beating. I love the look but they will get tore up! By tore up I mean, scrapes and dents and gouges. That aluminum bar will be coming off in shavings against hard rock just like your end mill did to it. Won't be pretty for long. Don't go wiping your hand along the bottom outboard edge either or you will be wearing band aids for a week. Over kill it and attach a few braces to the chassis.

6061 of course! And yes using aluminum in such a high impact area will have its issues. But worry not, I’ve got a plan .

Max, I KNOW you will have SOMETHING different! Lolol. You are very creative and resourceful.

From your earlier post on material costs, it is CRAZY what price swings there are in materials n ow. Its this crazy country of ours letting manufacturing raw materials as well as all types of manufacturing slip away.

When we built parts for many customers they had a list of manufacturing countries allowed for their raw material. I think its called DFARS. To many 3rd world and super power countries have very low production standards and inspections. If we were building parts for a customer who didn't mind say a China made steel we could save them as much as 60% on material cost. I do NOT know why steel has cought up with Aluminum in cost other than more countries are producing more Aluminum.

I know in the year and 2 months building my car, if I built it today parts and materials would cost me $10,000 more than I spent!

Looking great as usual. Your engineering skills are impressive!!! Looking forward to KOH23 and I'm hoping to attend, as a spectator. Have you considered using HDPE as a skid plate cover? It holds up pretty well and is slick over the rocks. Just a thought.

Great minds think alike! I already picked up a 4x8 sheet of UHMW (holds up a little better then HDPE) 1 inch thick. Going to plate from the rocker to the frame for a nice slick surface.
