Not a gunsmith but am mechanically inclined. After reading up on the topic I will be reaming a .32 caliber revolver chamber from .32 Long to .32 H&R Mag. This will be manually done with a T-handle, and since I can't justify purchasing a gallon of cutting oil for what will likely be a single job I would like to know the best recommended option for a cutting fluid for this task. I'm neither adverse to buying from Amazon nor making my own home-made product but just want to do the job safely, effectively and as economically as feasible.
Suggestions?
