Hi, I am Elliot, I live in Birmingham, I am a retired engineer and I am new to using forums. I am not sure which forum is the most useful so I apologise if you read this note multiple times. I purchased a very old HLV-H last week and have started the process of getting it to work reliably and with reasonable accuracy. Thanks for a great fund of information. Using this forum and others I now have relevant manuals for operation and maintenance, some wiring diagrams and a parts list, all of which seem useful. Special thanks to Bill Todd who has got me off to a good start. I am currently working on the variable speed drive and the spindle brake. The spring in the spindle brake appears to have broken. The piece I have has one neatly closed end and one broken end. Does anyone know what the correct length and spec are for this spring? Thanks. I look forward to contributing what I learn to this forum.
