Homemade Leg Press Machine

[@sergiomanoeldeaguiar8093]

“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!”

[@fre780a]

Le problème concernant cette machine, ce n'est pas le prix car elles ne sont pas très chère. Mais l'encombrement. Je n'ais plus de place dans mon homegym... Il faudrait que j'imagine une machine qui prenne le moins de place possible et qui soit pliable.. Pas facile... Cela dit, c'est toujours un grand plaisir de fabriquer soit-même sa machine de musculation. Bravo pour votre travail !

[@garciacindy2035]

This is exactly kzbin.infoUgkxUHHotQRjIQnfuxEeVotlkHVYWH0DXZoS 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.

11:51 la maquina hace ruidos como si estuviera gimiendo xd, pero buen trabajo, te quedo muy bien

[@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?

[@竜卷男]

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 ).

[@giuseppebruno8982]

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

[@竜卷男]

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

[@johannao4849]

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

[@竜卷男]

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

[@竜卷男]

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 🙏🏼

[@竜卷男]

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. Visit my new you tube " Homemade Leg curl & extention Machine "

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

[@竜卷男]

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

[@phillipstevens8148]

Wud u share the sizes of ur material, the hole diameter bolt sizes n wat bearings are u using. Magnificent craft

[@竜卷男]

Thank you for watching. About measurements, see the reply to Sr. Caique and Mr Aldimo. Bolts at the corners of main triangle structure are M-10. Fixing bolts for chair pipes are M-8. ☀Q.

Hola excelente maquina, como podría conseguir los planos

[@patriciogomez73]

Cuáles son las medidas de los cortes de todos los tubos?

Quanto puoi caricare ?

[@mikemerc74]

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

[@vijaybadekar9744]

Great idea sir👍

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

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

[@竜卷男]

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

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

Medidas por favor

[@danielmcbain7866]

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

[@竜卷男]

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]

@@竜卷男 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

[@竜卷男]

Thank you for watching.

[@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.

[@竜卷男]

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]

@@竜卷男 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.
