How do you go about repairing that shock mount?

I have done some work on this, but off and on, with regular work schedule getting in the way, Sean stopping by on his Belfast 2 Belfast rideabout needed to work on his bike and my buying more used parts, cleaning them up and shuffling stuff around in the shop, worked on and fixed my K5 wiring problem and I haven't updated this thread in a while even though I did get a few things done on it, so here's the updates....

Made the decision to clean up this frame and paint it as a friend wants to buy it as a rider.

A few weeks ago I cut off the remaining threads of the shock mount, drilled a hole in multiple sizes up to the 8.8mm size listed for the 10mmx1.25 tap. The drilling went well until I got near the weld point of the mount to the frame, the welds hardened the steel, dulled up a few drill bits but got it to a good depth finally. I had to get another tap as the tap and did set had a bottom tap in that size and it wouldn't start tapping. Talking with a friend who told me to get a starting tap, they have a tapered end to start the threading. That made the difference, followed up with the bottom tap. Cleaned out the oil from the threads and put some Loctite blue on the threads and tightened the stud in place. All better.

I sent off the 2 gas tanks and 2 dented oil tanks to the PDR guy a month ago, he called a week ago and said he couldn't do the oil tanks as they are too heavy gauge steel and was getting going on the gas tanks. Hopefully hearing from him soon. So I will be looking for a K6 oil tank that isn't dented.... of course the K6 oil tank is a 1 year only because of the changes in the rear vents but maybe I can make an earlier tank work.
I bought another set of 086A carbs at a swapmeet in May that aren't monkey fisted, did an initial clean in the ultrasonic tank and still need to finish them up. I might use a friend's vaporhone on them if I get the time to do them up nicely.
This afternoon I will head over to my sister's house and stay with my mom while my sister goes camping up on the Maine coast next week so I won't get anything done on this after this morning for the next week. But I'll get some good time with mom.

I like your shock stud repair  ;)  Did you use a hardened stud(10.9 or 12.9?)to replace it ?
Did you use hardened drills and taps ?
Where did you source your materials ?
Stu,would air pressure pop the dent out of that oil tank you have ?

Not sure that the stud is hardened? Bought at Ace $3.09
Cobalt drill bits after my old bits dulled up fast. Amazon $50/set. And had to order an 8.8mm drill bit from Amazon as there wasn't one locally.
Taps, have a set from HF, Bought a new Irwin 10mm starting tap at Ace

I see.
I imagine you finished tapping out the depth of the hole using the bottoming tap;did the tap struggle going through the hardened steel toward the bottom near the weld ?

Thanks, Stu! I always wondered if those bolsters were hollow or not, in case I'd have to do what you just did. :)
So far, I've been lucky not to...
