"jump", verb, in iron-working

[Eric Nielsen]

I found a few occurrences of "jump an axe":


“Ventling went to Bodines to Jump an Axe for J. Johnson”



http://www.bassriverhistory.org/uploads/6/8/7/1/6871754/bass_river_notations-_martha_furnace_diary.pdf
on page 3.



“and he can forge a handsome horse-nail already ; he can plate and temper a
hoe, set a sleigh-shoe, and *jump an axe*;”

"Jump" seems to refer to a repair of some sort.





A "jump weld" is to join pieces at a right angle:



“In making a jump weld with stock as shown in fig. 35, a short piece of
1-1/4 in. square iron is jumped onto a flat piece 3 X 5/8 in.”



*Hand Forging and Wrought-Iron Ornamental Work*

 on page 61 of the pdf.; page 64 of the publication.



I may be jumping to conclusions, but could it refer to attaching a handle?
