I went to test fit my cones to make sure that the compressor thread was the correct one and to my surprise could not get it to fit. I reversed the cone and managed to get the thread to go in that way, then turned it over and worked it to find that even more rubber came out. It would appear that some rubber ingress from the moulding is the issue but once cleared, the thread works fine. I then went online and saw someone else make the same discovery, so thought I'd best share on here. Cole (Does the 7 Mini vids) in the US actually destroyed his trying and describes them as 'cardboard', but I think it is a dirty thread issue, not that they fell apart as he seemed to think.

So if you buy these, clear the threads first. https://www.youtube.com/watch?v=CEiK1ejofWs

I think that's a good call to clean the threads on new cones. I've found on just about all of them, the thread has some rubber in them. I also always clean the threads in every time prior to fitting the compressor tool. A dab of grease in the threads here slow down any rusting of them too.

I had the same problem with red spot cones, I always clean the threads now to be sure.

I have a cone compressor that someone made. It came with a tap welded to a long bar, to enable the thread to be cleaned out with the cone in-situ.

Either that, or it could be a total bodge and the bloke who made it only had a bit of whitworth all-thread, so had to make up a way to re-cut the wrong thread into the cones. I've never used it.

Good to hear, you may wish to check out Cole's video and what he says at the end? (32:33 mins)

He used the imperial tool in a metric cone and stripped the threads...

Also, there were two different thread pitches used if you were thinking of running a tap down any cones. Before 1976 they used imperial threads, then switched to metric when the single bolt front subframes were introduced. I'm not sure what the replacements use for thread pitch, but it's worth the mention.

Ouch, that wasn't mentioned now was it!!! Can't recall the last time I used the imperial rod!!

Nope, someone mentioned it in the comments and he admitted to using the wrong tool but didn't correct his video :/

The passage in question.

Always amazes me how fast people are to criticise & how slow they are to correct their own mistake.

Exactly that! I wonder how many bother to read the comments and just take the video as gospel, the internet is a dangerous place...

and just to add, the Minispares compressor tool's thread has a nice starting channel that helps to clear the excess rubber out. Better than my original (that I found after buying one!!)

Agreed. The Thread is like a thread / tap, will usually clear any crap out of the threads as it goes in.

So does the original Churchill Tool......
