Frame Straightening? Park HTS-1?
Does anyone know if there are any shops or hobbyists who do minor frame checking and straightening?
There was formerly a tool called the Park HTS-1 that would push-out small bends in a frame by pushing on the head tube. Ideally I'll locate a HTS-1 (probably worth having one anyway), but I'm willing to have the frame straightened by a person or shop who does that kind of work (I'm in the eastern US). I have an electroforge welded frame with a very slight hump in the top tube I'd like to have checked and straightened. I see no bulges or other damage besides the slight hump. I have the project pulled apart and might as well have it gone over while everything is apart.

Most framebuilders can do this but I suspect an electroforged frame presents a special challenge so might be harder to find someone.
You could start with these for a consult at least.

The Brute would push on the fork as well, which I am looking to avoid because the fork seems to be alright.
The issue appears to be entirely confined to the top tube, a fairly gradual hump of between 1/16" or thereabouts deviation from straight, about 2-3 inches back from the weld joint. No cracks, folds, or distortions in the tube that I can see. I would think the HTS-1 would be the way to straighten it in fairly simple fashion and without too much effort.

I'm with merziac, I have two frames done by a local frame builder at a reasonable cost on his Marchetti frame table and Laing fork table, outstanding results. One a Reynolds 853 that Reynolds will tell you can not be cold set.

I had a local shop straighten a steel frame, Specialized Crossroad, that I had given to a friend. He accidently ran over it, but, fortunately, only the fork was ruined. I do not know how they did it, and they could not get it completely straight. but could not tell when riding.

can be employed without a need to press upon the fork
remove fork and use steel bar through the head tube
