There are two brackets on the pedal bar on my old Sho-Bud that hold the 'crank' in place on which the foot pedals rotate. The crank is held in place with a grub screw that is tightened with an allen wrench through the bottom of one of the brackets.
I seem to have 'shredded' the thread on either the grub screw or the bracket itself when replacing after cleaning and re-lubing. I've made a temporary 'fix' with a Jubilee clip' (at least that's what they call them here in the UK - a 'circle' of aluminium with a thread that screws tight to join piping etc - plumbers use them a lot). I would like to fix it properly. Are the grub screws available to buy, does anyone know? I'll need to have the bracket re-drilled and threaded to take a new grub screw but I guess an auto shop might be able to do that. Any other suggestions? Maybe a new bracket? I'm sure this must be quite a common problem because the grub screw is very small and easy to mis-align when replacing, which I suspect is what happened in my case.
All assistance/thoughts gratefully received. _________________ Ben-Rom #017 'Lorelei', Guild D25, Epiphone 'Joe Pass', Roland 40XL, Hilton VP

you could probably retap it yourself. alyoumineeyum is pretty soft. i'd call that an axle rather than a crank. |

Thanks guys! Would I be right in thinking that the next size up would also ensure a grub screw could be obtained (or something similar that would do the job)?
Chris - I couldn't do this myself. I elected to do 'metalwork' at school - you guys might call it 'shop'. My teacher said to me (in full Lancashire accent),
"Have you got a sister?"
"Yes, sir."
"Well I bet thy sister shapes better than thee".
Yes, in the 1960's in Lancashire they still used 'thy' and 'thee'. ['Shapes' means 'could do'.]
He was right. Pedal steel guitar is a challenge for someone as un-mechanical as me. (Although I do understand the term 'axle' being better than crank.) _________________ Ben-Rom #017 'Lorelei', Guild D25, Epiphone 'Joe Pass', Roland 40XL, Hilton VP

An automotive machine shop could take care of it in ten minutes. _________________ 2 pedal steels, a lapStrat, and an 8-string Dobro (and 3 ukes)

Like said before, drill and tap it to the metric size larger than the original, and those screws should be found all over. When you put the block back on the shaft, file the burr off on the axle. then install, and do not tighten too much. Just snug it up good. there is no pressure on it so you don,t have to tighten too much, and strip the aluminum again. Very easy fix. Good luck, Ronnie _________________ Sho-Bud LDG, Martin D28, Ome trilogy 5 string banjo, Ibanez 4-string bass, dobro, fiddle, and a tubal cain. Life Member of AFM local 142 |

The set screw usually grubs a dymple in the crank. Last ShoBud I did I had to file the crank smooth, so,,, I actually filed a flat for the grubby screw to sit, and used a flat-ended set screw, and a little dab of Loktite. _________________ Dr. Z Surgical Steel amp, amazing!
