My 8 x 30 grizzly mill was just too small to do barrel fluting. I have use a friends 9x42 many times to flute my barrels and I was very happy with it's performance. Another friend's relative succumbed to Covid around Christmas. I purchased the contents of his garage. Included was a 9x42 Enco mill. (1980 vintage) I got it home last week along with two trailer loads of Machinist tools, materials, power tools, a "new in the box" Kurt II pt600 vise and of course, a lot of junk. The mill was pretty clean. I was told that the mill had not been used in at least 15 years, maybe longer. It is a step pulley machine that seems to be a perfect clone of the Bridgeport J head machine. The v belt looked a bit worn so I decided to change it. H&W Machine repair of Fort Wayne Indiana has a great uTube series on completely rebuilding Bridgeport Mills. Barry (H&W) makes everything look simple. To change the belt, the motor needs to be removed. As long as I had the motor off, I decided to change the bearings in it. One thing led to another and now I have the whole top half of the head stripped down and cleaned up waiting for the bearings to arrive. I did manage to find a user and parts manual to download. It provided me with the metric sizes of all the bearings. After watching the great videos by H&W, I feel confident that it is doable. I ordered the spindle bearings under the premise of "no guts, no glory." The only thing that I am having issues with is the brake shoes. I see them on Ebay and the H&W website for Bridgeport's but I am unsure if they will fit the Enco mill. Does anyone know if the Enco 100-1527 is the same as a Bridgeport J head mill?
