I love this!!

You're welcome! I really appreciate the kind words and feedback.

Very good point! And Dad was definitely not warmed up or in proper clothes. I did put in a disclaimer about the times...I suppose you'll need to write an essay about it to set the record straight(er). Until then - you don't really have to worry about many people watching this. 🤣

Awesome! Let me know if you come up with any improvements. I'd love to hear how it turns out.

Glad to hear it!

Let me know how it works out!

Excellent! I love the d-ring anchor idea. And then you connect to it via a carabiner?

@@MaddenScience Yes! The carabiner on the TRX straps I usually use works well. I have another carabiner and soft tiedown loop to anchor my battle ropes to it so I can use it for other things. Part of the fun of it is figuring out other ways to use it 😃

Amazing ideas! Keep me updated - I'd love to hear how it turns out.

Excellent!

That is a perfect combo!

The two sleds I made are pretty quiet. I've even talked on the phone while pushing/pulling and it's no problem. Definitely not loud for neighbors. As for how loud compared to a regular sled - I'm not sure - I don't think I've used one of those on the street (just inside of a gym on turf). Either way, I think it'll be good!

I love it! Great idea.

Pretty close! The bottom is made with 2x6s. 24" long, and set at 12" in width - meaning there is a 1" gap down the middle. The ends of those 2x6s are cut at 45 degrees - with the horse stall mats screwed into the bottom flat part, and the angled front and back slanted part. The cross pieces are all 12" long. The two end pieces are 2x4s (so ~ 3.5" in width), and the middle piece is 3" (not totally sure why, must've been a scrap?). The spacing is such that it's balanced spatially to hold the powerblocks. That means there is ~5 7/8" gap between the pieces in order to fit the powerblocks. Hope that helps!

Good question. I'm not sure. Depends on how rough or course the ground is, how much weight is on it, and of course, how much usage. My guess would be even with heavy use (both weight and time-wise) it would last at least a few years before needing to be replaced.

I used horse stall mats on the bottom. This was to add more friction (just wood was too smooth and easy) and to protect it. Works really well.

You could buy a sheet of UHMW plastic and attach it to the bottom. I’ve done that with a traditional sled to keep it from damaging the street, and the sled itself when I drag on asphalt. It’s relatively cheap. I haven’t had any issues with it not having enough friction, but my sled also has much more surface area contacting the ground than the wood skis in the video.

Very good question - depends on what you mean by "little". It does not leave any naked-eye visible pieces. Nothing is noticeably flaking or sloughing off (I assume that's what you're asking). However, on the microscopic level, yes. There is wear and tear and so some microrubber pieces are being broken off the tire and the stall mats. Similar to this - only we're outside, so things don't accumulate in the same way. www.newscientist.com/article/2428422-indoor-climbing-wall-users-may-be-breathing-in-toxic-rubber-dust/

I love it! Great set up. How big is the truck tire? How many bags of quick crete do you end up using?

@MaddenScience it's a 275/70 r18. I I have 5 60lb bags I work up to.

I didn't mix it. I just toss the full bags in instead of adding plates. Just a cheaper option.

Hmm. I'm not quite sure. I big tractor tire is going to be super heavy and have lots of friction. And be a bear to cut or reshape or remove weight from. I think the only option would be to try it on a lower friction surface - like grass or dirt or leaves or maybe loose gravel? Might need to get a smaller tire... (should be able to get one free at a tire place - just ask for an old beat up one).

They hold up really well. I thought at first that the screw attachments might wear/break off - but they've held up perfectly. The stall mats have worn a little bit, probably the same as the regular tire - but that's only a little bit - kinda like a sneaker that's worn slightly.

@@MaddenScience ah, thats good to hear. I checked on amazon for the price of those Mats. Its about $35 USD. Was concerned how often i'll have to replace them lol. Thats I will give these a shot

@@mustbescud you could also consider lining the bottom with tire tread. You can get a tire for free and cut it up and screw onto bottom. This would take more time and effort than the mats. I happened to have a mat lying around - and I only used about 1/4 of it.

@@mustbescud Nice! Keep me updated with how it turns out. *I use the leftover part of the stall mat for plyos and jumping rope.

Good point - I used horse stall mats on the bottom. I cut those to size and then fastened it on using screws. It increased the friction and made it way better.

@@MaddenScience Thanks!!!

You can use straps (like a TRX or my homemade version) for pushing - you are still in front of the sled, you push against the handles and the straps provide the tension. Just like in on the video's thumbnail picture. Admittedly, this is one area where a regular type sled (Rogue dog sled) is a little better because it has vertical metal poles to push. In order to have this equivalent, you'd need to go with a wooden or metal base, so as to adequately secure 90 degree/vertical poles to push. You could make a wooden base and then use plumbing pipes and flanges.

The ones I used are 1/2 inch thick.

How so?
