The machine is from 1954 and Im completly rebuilding it and need help/assistance with the feed gear box. It would be better to talk to someone on the phone to fully express the problem in detail! Pretty much I am having a problem with the automatic feed reversing direction when it hits the dogs. If you are or know anyone that has operated and/or repaired such machine please let me know. If anyone needs pictures to confirm my machine, I will take them. Please help if your familiar with Heald grinders!!
