I was waiting for some bits to arrive for my engine, so I thought I'd have a play with the Stomski jig and see if I could remove some broken bolts out of the heads.
This head had two broken bolts in it. Exhaust manifold surface cleaned up and the heads of the bolts levelled off with the grinder.
Jig attached at two points, using a pair of the inserts to line up over the broken bolts
Pilot holes drilled
View of the pilot hole.
Larger drill used to remove the rest of the stud.
This is what it looks like after it has been drilled out.
Any parts which can be picked out with a pick were, Than I ran a tap down the hole to clean it out properly.
I did a total of five of these over three heads, no problem at all. The drilling takes a bit of time, but then it is going through about 20mm of steel so it is to be expected.
I did a short video as well so I'll probably add then when it has been edited.
