How heavy is too heavy for homemade sliders?

So, to preface this, my workplace recently cleaned out some unused stock and let the welders rummage through the scrap bin. I ended up with about 12 feet of 1 3/4'' solid bar, 6' or so of 2x1'' solid bar, 16' of schedule 80 2 3/4'' pipe (1/4'' wall thickness) and some assorted 1/2'' and 3/4'' plates. I plan to fab up a section of channel to go on and around the inside my frame and bolt my homemade sliders to the channel, in effect boxing the frame in. I know this will torpedo my MPGs. I just want to know if somehow this may damage my frame.

Most sliders are 50 to 60 pounds each side

 

Sliders didn't really effect my MPGs. Are you welding to the frame?

 

No, they'll be bolt-ons.

 

Does seem you could hit a point of diminishing return. Most people have a hard time denting 0.120" wall tubing so it would seem like solid bar is beyond overkill. But I suppose whether your sliders weigh 125 lbs or 250 lbs isn't going to matter that much. But it all adds up.

 

Yeah, the attraction here is this stuff is all free. The gas, the wire, the materials. Only thing I'd spend is some time building them.

@Tacos in Gensokyo
OP to give you a rough idea, assuming your going to use the 2 3/4" pipe for the majority of the work. Your weight add on is at least (not inclduing misc gusset plates or steel add on) is ~10.4 kg / Meter. So you can easily do the math on that weight addition if you do a rough sketch and dimension drawing.

 

Exactly. Just look at this video. Any properly built slider is gonna be tough.

My @Pelfreybilt sliders with kick out weighed in at about 75lbs each! Plus the hardware and front mounting plates that sandwich the frame.

 

Yeah, it's just that this is free. My shop dosen't usually work with small stuff like this, so getting anything smaller would be on my dime.

 

My main concern would be somehow deforming the frame by hanging too much weight off the side of it. I don't think these things will come out at anything less than 100 lbs. per side.

EDIT: Might be more like 150 lbs a side.

 

Your frame? I'm gonna say no way.

 

I'd bet more than that. Regular sliders are about 70 to 80 lbs per side and solid 1.75" bar is a bit more than 8 lbs per foot.

I doubt the frame will care about +/- 100 lbs. When you use your sliders you put 5000 lbs on them. Sure will be a PITA to get into place, though.

 

Yeah, I suppose I'm just being paranoid. Probably just build them and see what happens then. I agree they'll be way overkill though.

 

Yeah I think the frame is layered there, almost like 2 layers.

 

Plus if he boxes them in a little that helps. That's what Mobtown does, they have a bracket that wraps over the top of the frame and connects behind it.

 

Considering the final weight of sliders are going to be 100+/- per side I think that would be a great way to go bolting them on.

 

I would not use the solid bar stock. I am making my own sliders now with various 1/8” thick DOM tubing sizes. I just need to make the slider to frame bolt-on extensions. It is too cold to mock-up the parts, so it will wait for better weather. My buddy let me use his fabrication shop after Christmas and the right machines make the job so easy. The weight can add up fast, if you don’t watch it.

 

Seriously nice looking sliders.
