Recommendations for stud extractor / setter

[Colin Wilks]

I need to remove and then replace all the studs on my block. Years ago I used mole grips or small Stillsons for this task, but have decided to do the job right and buy the proper tool. I can see Austin Seven ownership involving quite a bit of stud work over time.

Please may I have your recommendations about the best tools please?

Many thanks,

Colin

I've just bought the Sykes Pickavant set of metric gripper/remover things which were about 24 quid on ebay in the sale. They are mentioned in another recent thread which is why I thought they were worth trying (plus diesel and acetone).

The only tool I've found to do the job properly is a Blue Point Stud Extractor. Photo enclosed. The only time it has ever failed me is when the stud is corrosion wasted and has snapped.
Not cheap, but worth the money.

That’s what I have too. Usually works. If it doesn’t what I normally do is cut the stud down and weld a 3/8 nut over the end. The heat must free things, it’s never failed yet.

Here's a previous Forum thread on the subject of stud removal / extractors / setters ...........

If looking to use a penetrating fluid to assist in the removal, I can recommend the following:

Thanks for that Jeff. I had just remembered the search facility on this forum and found that thread. I was on the point of ordering 1/4" and 5/16" Koken stud extractor/setters before making my original post. I shall now go ahead with those. 

I loved the YouTube video of the guy easing wheel nuts with a lighter and a candle. A good trick if you're caught out at the roadside without a breaker bar to get the wheel off a modern!

I've had a Sykes Picavant imperial set for years but they don't seem to be available any longer. Given that I've used them on metric studs sometimes, I imagine the metric version will work fine on imperial. What does help, if you've got the facility, is to heat the base of the stud with a gas torch immediately before removing it. However corroded, that usually means I can get all the studs out without breaking any.

At first I didn't find the imperial items on the UKTools site, so was wondering about using metric extractors on imperial threads, particularly 1/4" with the 6mm job, although 8mm and 5/16" are within a gnats.

Alan, that's what I do, normally get the welded on nut absolutely red hot with the MIG welder
Then wait for the redness to go before turning, if done while still red it will just twist off which is not what we want.

Hi Colin, I have just removed studs from a block using the tool similar to the one pictured by Chris (also applying heat to the base of the stud). It's grip on the studs was excellent, but it is not easy to 'back' (turn it back in a tightening direction) without it then loosing its grip.
