DIY Shaft Extractor Finished

[MIKE1218]

Not to be a SCHILL, but I can get anyone a good hydraulic puller(same one I use) for around $100. I won't be making a dime off it either. Same one you see pictured on my bench.

I think the point is to make it yourself for $30. That $70 might matter to some people.

If you're going to go with hyrdaulic, there are better options than that one. The 'Wild Willy' puller is $90 from a guy on WRX, and a much cleaner, and more compact design.

Or even better if you are tight on space is the Greenseekers', for just $70.

Personally, I think hydraulic is complete overkill for this job, and I didn't want to deal with bleeding the jack, and/or replacing seals. If someone used an old American-made jack, that'd be different, but all the cheap jacks are now made in China, and mine don't last more than a year or two. Some of my scrap aluminum pile are re-claimed pieces of cheap jacks with ruined hydraulics that weren't worth fixing.

For me, anyway, the point is making it myself... saving a little money is just a bonus.

That said, if someone isn't into DIY, by-far the nicest affordable extractor I've seen is this one, constantly on eBay from csbauctions.

A couple months back, they used to sell for $50. Now they're up in the $60-70 neighborhood. I'm impressed that they can sell it for under three figures thought, from the amount of a aluminum machining involved.

This looks like the easiest setup around. Just need to make that adaptor piece for the top of the jack. And how often do you use a bottle jack that they are wearing out so often? I have a couple, 1 of them is a newer supposedly inferior chinese piece of crap but it has always worked with no issues at all.

It's not Willy's. Let check with the guy and make sure he's still selling them and I'll let you know. Altho' the above one looks pretty good too.

That design is especially nice where it minimizes the distance between the shaft and the application of force. The larger that distance, the more lateral force on the tip of the shaft.

Well I don't own a bottle jack, but when I was racing, I'd kill a floor-jack in a season or less. More to the point, though, I bought several which were leaky after just a few uses.

Think about it... you don't even need any mechanical advantage to pull a head off once the epoxy is heated, just grab the head and twist it off. The problem is, you'll wreck a graphite shaft if you twist, so it needs to come straight off. Otherwise, you could do it by hand... so obviously 4 tons of hydraulic-assisted force is unnecessary.

 

[LBlack14]

Yeah , but 4T of H force sure makes things EASY.

The guy's got a couple now, said he wants $110 shipped. They work great!
