I thought that we could use a thread here for the little guys. I have often wanted to post something but there wasn't a general thread for those of us with GTs and LTs.
I will go first.
I had them out for some fine tuning yesterday. I have done a little trick with the reverse pedal on my 4x5 machines. They don't have a lot of speed from the factory in reverse and there are a couple of kits available to provide more travel. For me, it seemed more simple to get out the torch and give the shaft a little tweak. With the sheet metal off and the pedal removed, you can heat the shaft red hot and give it a little twist. I had done this befoe but went a bit too high so I adjusted it.
In the photo attached, you can see that it is a bit too high and is awkward to use. If you set it so that the rearmost corner is just at the foot area, it works great. No parts, and no money spent. All four of them are now full speed backwards.
