Armor removal and armor screws

[universalgrl]

As I was a master aircraft technician I learned the correct way to extract frozen screws.
I saved ALL the screws on my carriers front plate including the 4 1/4 inch screws for the log book holder.
Use a penetrant of your choice (over several days) I use wd-40. Use a dremel with a fibre wheel to clean out the screw slot and remove burrs, make sure the sides of the slot are parallel to each other.
Make sure your tool bits are sharp and don't show any signs of twisting, the bits can cam out otherwise wrecking the screw slot.
Impact hammer with the extractor and appropriate bit or hand held impact and a zero bounce hammer.
If all else fails MIG a tack weld on the screw and attack the fastener on the other side, nuts are cheap.

Lots of ideas to choose from here Gina. You can mix and match from dead blow hammers to blue tongue spanners, from shouting a curse to emptying your purse.

The "No golfer plays with a single club" rule is spot on.

3/4 drive drag links hard to get so have one on back order from the states. ( snap on as advised by Steve)

In the meantime ground down a hex drive and now have thirteen of the 5/8 screws undone and only one of the 3/8.

A T bar with a couple of lengths of water pipe to give extra leverage has done the best so far.

The rattle gun is impossible to keep in for more than a few hits and it damages the slot dreadfully. I will take my Big Hitter rivet gun with a slot snap and give them all a good rattle.

I will also hit them with some heat. Heating is a bit of a hazard given the amount of oil , grease etc built up in the engine compartment and the risk of fire.

So far bit over half of the big screws on the rear armor. First time out since 1942 so far as I can tell.

Below reground home made drag link ( about five grinds for ten screws) I use grinding paste in the slot to assist with keeping the blade engaged. The screw has been polished to colour parade colour standard :/

They were probably made to be used with an inertia wrench.

If you've not seen one it has a large rotating disc like a dumbbell weight that you spin down the length of the driver, building up inertia, and then it suddenly grips and transfers the inertia at the end.

Ahhhh another club for the bag do you have a link to a photo??

Here you go. This is an Atherton type Inertia wrench. Theres a 18" ruler for scale. It's a heavy lump which broke my other half's toe, hence not popular in our household... (a timely reminder to be careful with your tools)

It comes with a kit of tools including a strap to go around you neck (to brace against your chest) and a stand for working on lower bolts.
