Nice trick with the nail

[@whitedoggarage]

Yes it was, just needed something the right size to modify at the time. Thanks for watching 👍👍👍

1:48 what causes both holes to strip? cross-threading? over torquing? normal wear?

[@whitedoggarage]

Those holes are some of the hottest spots on the motor, which might be a factor causing the aluminium thread to bind and eventually strip. I have worked on a lot of old motorcycle motors and thread stripping is not unusual, so binding might be a thing. Interestingly I always put anti-seize on sparkplugs, because stripping that thread on an aluminium head is a right pain, but never on these. Thinking about when I have replaced the spark plugs on relatively modern car motors, those plugs were factory fitted and no anti-seize used there and they are quite hard to undo. Now those plugs would have done 60,000 miles at least, so maybe they do tend to bind to the aluminium with time.

10:17 I would think the thread locker would help when pulling the bolt the next time? you mentioned one insert pulling out, is that as common as the stripping?

[@whitedoggarage]

Inserts pulling out is uncommon, they are stainless steel and that usually locks pretty tight in aluminium.

[@SuperBossman9]

Do you ever find the fabricated inserts work their way out? After the bolt had been removed a few times?

[@whitedoggarage]

Yes, I have had that happen a couple of times. I have though about putting thread locker on the inserts, but have yet to do it.👍👍👍

Size of socket please

[@whitedoggarage]

The socket use din the video is 1/4 inch e-torx or star drive. However the square drive on taps are not all the same size and I would take your tap along to your favourite tool shop to make sure you get the right fit.

5:02 if you have a lathe and time, I'm probably going to be a method #2 guy

[@markwhalen5300]

(it was fun to watch!)

[@whitedoggarage]

I prefer the inserts too, much less time to fit.
