Homemade Leg Press Machine

[@garciacindy2035]

This is exactly ua-cam.com/users/postUgkxUHHotQRjIQnfuxEeVotlkHVYWH0DXZoS what I needed to get some exercise while I'm stuck at my desk all day. It's just the right size. Only downsides are that the right oeddale unscrews itself while I use it and increasing the tension causes it to squeak while in use. Both are minor issues that aren't that important to me. So I give it 5 stars.

“Hello! I’m impressed with the quality of your work. If possible, could you create a demonstration video? If that’s not feasible, it would be greatly helpful if you could share the dimensions of the machine you built. I live in Brazil and am interested in building a similar unit for home training. Thank you in advance for your attention!”

Ficou muito bom... parabéns.

[@johannao4849]

Ett imponerande hemmabygge! Och ett rejält projekt att ge sig på i pandemitider. Jag är glad att du håller igång! 🙂

Tack för att du tittade. Vi önskar världen utan Covid 19.

[@alainteran8086]

Can you add the dimensions for the seat, foot rest, the size of pipes used and size of bearings of sled please 🙏🏼 fabulous job loved it

[@user-hv3pz8kb8d]

Thank you for watching. The pipes of seat and foot rest are same size. Their outside diameter is 25.4mm ( 1.0' ), wall thickness is 1.6mm. And sheathe pipes are 31.8mm ( 1-4/1' ) od, thickness 1.6mm. Thank U.

[@alainteran8086]

What’s the size of the rolling bearings and plain bearings 🙏🏼

[@user-hv3pz8kb8d]

The outside diameter of main wheels are 65mm, guide wheels 38mm.
Make reference to
www.hammer-caster.co.jp/catalog/html5.html#page=361
Main wheels are 429S-NRB φ65 on page 326, guide wheels are 429G-N φ38 on page 324 .
Main wheels have ball bearings inside. Guide wheels have no ball or roller, just through holes.

do you have the measurements? please add to the description the measurements of metal.. this is awesome! you're a great welder vlogger!

[@user-hv3pz8kb8d]

Thank you for watching.
About measurements, see the reply to Sr. Caique and Mr Aldimo.

[@giuseppebruno8982]

what kind of mechanism and bearings did you use to have smooth movement without blockages?
Great project

[@user-hv3pz8kb8d]

Thank you for watching. Main wheels have roller bearings. Guide wheels have plain bearings. Also all shafts are stainless steel bolts. Thank U.

[@mikemerc74]

I think better support for the seat and a liite grease on wheels and a safety mechanism it will be all right

[@vierdoesit]

And I thought my leg extension/ leg curl machine was cool… Good work dude!

[@user-hv3pz8kb8d]

I've watched your leg extension/curl machine. It's excellent ! Thank you.

Good job. Be carefull. The execution of exercice is wrong. You will damage you knee doing it this way. Keep safe.

[@user-hv3pz8kb8d]

Thank you for your kind advice. I will do without knee locking out to safety.

[@mosesgitari9085]

Nice project....do the pulleys have v groove? What prevent trolley pulley wheels from being lifted up the rail as you push the load up with your legs?

[@user-hv3pz8kb8d]

Thank you for watching. Pulleys don't have any groove, only run inside guide rail C-channel. Trolley pulley wheels can not be lifted up anytime with their weight ( including barbell plates ).

No wonder they are expensive. Lots of labor, equipment and expertise building them.

[@fifis101]

Great job but very light duty. I would not want to put much weight on it.

[@andrewstutz4240]

That looks like .095 wall tube because of the angle most of the weight is coming back it’s more than strong enough and definitely not light duty.

[@fifis101]

@@andrewstutz4240 well I wouldn't be putting 300kg on it!

[@andrewstutz4240]

It would be interesting to see lol. I had to look closely at that tube if it’s bent 90 to flat and 90 again it would be pretty strong but it’s too hard to see exactly. I would build it out of box tube and have the sled mounted on top then you could weld angle iron down the length of it to hold the sled in place.

[@user-hv3pz8kb8d]

Thanks a lot for watching.
I had been a civil engineer for fifty years, designed many infrastructures. So structural caluclation is my field.
As Joshua remarks, I designed it's maximum load 200kg. You are exactly right.
Guide rail is made from C-Lipped Channel. It is popular in Japan. Also can be bought in US.
Thank U, Joshua and Andrew.

[@andrewstutz4240]

@@user-hv3pz8kb8d Ah, I see great job fabricating not a lot of working engineers left. I am a welder/fabricator working on nasa,airforce and military contracts. I have an orbital bender etc in fact I think you have most of the same types of equipment I used for my side jobs.

I know your using gasless MIG and flux core wire, but where the hell is your shroud and insulator

[@user-hv3pz8kb8d]

Thank you for watching. Yes, I'm using MIG machine as Semi-automatic welder with no gas. So I removed shroud which protect gas diffusion. This method is much convenient for cramped corner. But there ia a insulator at the base of wire tip. Thank U.

[@danielmcbain7866]

@@user-hv3pz8kb8d fair enough , I couldn't see an insulator , I bet you must go through a fair few tips and diffusers, even with reversing polarity. Nice build
