DIY sphere removal tool

Post by Xaccers » 11 May 2007, 16:30

It's been mentioned a few times and I really can't remember who first introduced me to it in a thread so I can't give credit where it's due, but here's how to make your own sphere removal tool from B&Q for around a tenner.

You'll need the following:
Box bar, about 2x2cm and 1m long (I think that's the shortest B&Q do)
M6 threaded rod, again I think 1m is the shortest they do.
2 washers for the rod
2 13mm nuts
An electric drill with a drill bit slightly larger than the rod
A metal saw
A round lamppost

Near one end of the box bar, as close to the end as possible, drill a hole through both sides.
Further up the bar, a sphere diameter away, drill another hole all the way through.
When no one is looking, use a suitable lamppost to bend the threaded rod into a U shape.
Insert it's legs through the holes in the box bar so the loop is lightly larger than a sphere.
Cut off the excess length leaving enough for the nuts and washers.
You'll now have a tool that looks like a P
Using the nuts, you can tighten the loop around spheres, and the long arm means a lot of force can easily be applied to loosen all but the toughest spheres.

An easier option is to buy a bolt type hose clamp , commonly known as a Mikalor , of the appropriate size. Tighten that around the largest part of the sphere and belt it with a soft hammer (dead blow is best) and alloy block or drift on the end of the clamp bolt. Thats been my method for a good few years.

You're being defeatist Nigel :D

Apart from being cheaper, it's also quicker to get hold of.

You sure? Round lampposts are ever so expensive...

Also, if you need the leverage exerted by a lamppost to remove spheres then you're doing something wrong...

Yeah in those situations then the pleiades tool is the one you need :D
When changing the rear Activa sphere for instance!

You've also got to consider when giving hints and tips that we have many members from abroad who won't have access to genuine sphere tools, or lampposts (in which case a suitable tree can be used).
HDI's suggestion is an excellent one for instance, anything which gets people away from resorting to bashing a cold chisel into the seam around the sphere has to be worth it!

I've got a funny feeling I'm going to need something more than my current twin chain wrench setup when changing spheres on the XM...

I bought one of these from Lidl, just fits over spheres and removes them with very little effort. Apparently Halfords sell them too (for about 5 times the price).

This tool is great for spinning off spheres that are already loose but it'll come up wanting (and in several pieces!) when faced with a properly tight one...

Believe me, some spheres can be unbelievably tight... I've had to cold chisel them off before now :twisted:

Here's a sphere removal tool I made several years ago when I had my first Xantia (1.9td) Hatchback. The loop fits snuggly over the sphere with the bolt providing the locking function, took about 20 minutes to knock this up using only what was available in the shed / garage / scrap pile. The handle is just about a foot long which, as I found out, is way to short as the spheres on my then Xantia had been put on hand tight by Goliath himself and needed an additional bar to get the spheres loose.

The same basic tool as Xaccers made can be used... It just needs to have a bigger hoop.

Otherwise, eBay sell sphere tools designed to fit C5 'saucer' spheres at a reasonable price.
