Looking for a Bottle Jack for a Hydraulic Car Jack

[Ludapower]

All car jacks use a modified bottle jack (modified base).
A car jack like this:

And a bottle jack like this, but with a modified base.

I'm trying to find a bottle jack with the modified base for a car jack. I'm making a car jack for a school project but can't find any spare parts for them anywhere.. Can anyone please help me find a bottle jack for one?

Thanks!

Welcome to PF, Ludapower.
To start with, they're both 'car' jacks just as they are. The first example is called a 'floor' jack. Secondly, not all 'car' jacks are hydraulic. All of the ones that I had, which came with the cars, were stand-up ratchet jobs. Most rice-rockets and some European ones came with 'scissor' jacks, which use a lead-screw. I have a 12-tonne bottle jack that I got for my 4x4 El Camino, but it certainly isn't industry standard.
As for adapting a bottle jack into a floor jack, you need only work out some basic math to determine your leverage ratios, and make sure that you use the proper materials in the design.

I ended up finding a perfect pump/piston for the job. I can finally get this project going, I'll try to get some pics up whenever it's finished.

How about a teaser pic

Here's where I'm at with this..

Looking good!

very impressive! Did you design that yourself from scratch or did you take dimensions from existing floor jacks? I like how low-profile it is. The floor jack I currently have is too tall to fit under some smaller Japanese cars - got to grab the fender and lift the body to get the jack under :)

I looked at a similar jack they had at CanadianTire (which is discontinued) and based it off that one. We decided to make it lower and correct all the defects that it had.
We're also using all aluminum and stainless steel parts. The only steel part are the 4 bolts that hold the pump and all the circlips.

Hey! Another Canuck on board?! Right on.

 

[Ranger Mike]

aye?

 

[Ludapower]

Eh! Yeah I'm from Quebec.

Eh! Yeah I'm from Quebec.

That can be forgiven...

 

[Ludapower]

Here's a little update after I cleaned it up a bit.

 

[andresdelsol]

it looks really good. I am pretty sure it will fit in my low honda del sol!

That's a very sweet looking piece of equipment, old bean.
What did you use for the engraving? (Or is that applied vinyl for the graphics?)

 

[Ludapower]

It's all engraved with a #5 Center Drill, except for the TGM 2009 which was done with a 1/8" End Mill. There's my name and my partner's name on the side. TGM stands for Technique de Genie Mécanique (Mechanical engineering).
I painted over everything then sanded it off and polished the aluminum.
Old bean?

You should resize your photos to 640x480 before posting them. That way it doesn't offset the entire page.

Old bean?

It's a British term like chap, or bloke, or mate. Just a wink and a nod at your froggish background; no offense intended.
Were the drill and end mill computer controlled, or did you do it manually? In any event, it looks terrific. It's rare to see great engineering and art combined so well.

Right right, I'm just not used to hearing that expression. Not all Quebecers have a french background.. obviously I do though :D
Everything is computer controlled

 

[Brilliant!]

Time for mass production. I'm not sure what it's like in Canada, but in the American south, a jack like that would sell like hotcakes. Especially if you put some Type R and NOS stickers on it.

You'll be a millionaire in no time.

 

[Ludapower]

It'd be too expensive. There's a lot of time put into it. Also the only materials used were aluminum and stainless steel. The SS alone makes it impractical to sell.
But yeah, Nos stickers would be sweet, it'd definitely make it go faster.

 

[Ludapower]

Mostly done :D

Specs:
- Two pumps to reach maximum height (with no weight on it)
- 2.6 inches of clearance when lowered
- 18 inches maximum height
- 1.5 tons maximum lift weight
- Materials include Aluminum, Stainless steel and 4140 Steel

Everything made by me and my friend of course.

Hi. I'm back for an hour or two.
Like any good piece of equipment, that thing looks even better in use than it did just sitting there. Congrats on a great project.

ludapower, I am doing a similar project, where did you get the huraulic jack unit from??

thanks!

 

[Ludapower]

I ordered a double valve pump from Canadian Tire, they had it shipped directly from Korea. I don't think they sell that specific jack anymore though. It wasn't very good quality though, I would suggest finding another similar jack and see if you can order the pump separately.
Good luck!

 

[1988ajk]

great, thanks for the quick reply!

i shall take a look, good design by the way!

 

[Ludapower]

No problem, you're lucky I still get emails from this place, I haven't been on here in two years hahaha.
I'm in Industrial Design now, everyone makes fun of the flames. I admit it's pretty cheesy :)

Still works great though, I ended up replacing the hydraulic oil with motor oil because it was leaking everywhere.
