My recently bought Fleetwwod caravan had lost its ALKO wheel lock along the way, and looking at the price, I decided to make my own! I'm not claiming it's as good as theirs, but any thief would have a hard job drilling out a solid 20mm bolt, or he'd have to have a pin key just the same (odd) size! BTW I'm not about to make any more as I hjave lots of other things to do!
Some pics:

I thought the idea was that the plate should cover two of the wheel bolt holes as it doesn't look much of a deterrent regarding the 5 stud wheel removal also the steel pin should be hardened and tempered so it meets the insurance criteria so it can't be drilled out with a tungsten carbide drill tip. It won't take much drilling out if the pin is only made from mild steel. Looking at the DIY wheel clamp, the wheel can still be rotated anyway so no drilling would be required at all if a thief can tow it away.

The wheel can't be rotated as the bolt locates to a receiver welded to the chassis.
If a thief comes with cutting gear to remove an Alko type wheel lock, nothing will stop them, they are going to take the 'van whatever. Apparently the damage caused by cutting off the receiver destroys the hub, brakes wheel etc, so would such a 'van be worth having afterwards?

Apparently not the case. On one of the forums somebody had their van stolen and the lock was left on the ground and could be used again.
make a spare key incase the one you have decides to snap the pins, I think it`s better than any other wheel lock you can buy, can you not stick some rubber on the back of the steel pad, stop it marking the wheel? Just a point, might be better to make the bolt out of stainless.

The lock may be reusable but the hub, brakes wheel, chassis etc will have been subject to something in the region of 3500 degrees C! Alko say don't weld their chassis - so how would you ever trust it - or insure it again?
Thanks for all of your interesting observations, all feedback gratefully received.
To answer as best I can:
1. The wheel can't be turned as there is a socking great 20mm steel bolt hard up against the receiving socket.
2. I tried tapping the bolt round (with a lump hammer - not a stone!) and there isn't enough torque to overcome the friction between the nut face and the alloy block, and also a well tightened 20mm bolt.
3. The wheel can't be removed because of (2) above: in fact I can't see the point of the Alko insert covering just two of the bolts. If one is that paranoid then why not fit a set of locking wheel nuts?
4. Any attempt to drill it out would only serve to tighten it up: it is not a flimsy barrel lock!
5. I know that if someone wants to take my van, then it will happen....

I would have made the bolt out of stainless, (I'm a time-served machinist) but have you tried screwcutting the stuff....? I will take your idea on board regarding the rubber pad and another (bigger) key. I suppose I could also look at buying a Range Rover coded key nut and making a matching head for the bolt!
