OMG! This guy is amazing. I would never attempt this on my own. This guy must have nerves of steel. He knows his subject well.

You are one of the best! not many people can talk, use tools, and camcord, all at the same time. I also like the fact you didn't edit out any of the time consuming parts of the video, you have shown what happens in the real world of disassembly, things do not always go as planned, further more, all of the important items and details were pointed out as you went along, and one of the best things, you didn't charge anyone a dime for your time and talents. Thank you.

I sure wish I would have found your videos about 9 months ago. I was very careful and managed to get it apart, but it took quite along time. I had to figure it all out. Thanks for sharing!!!!!!!!!!!!!!!!!!!!!

Thanks for the great video, I will be rewatching it again to get a better sense of how everything fits together.

Great videos. I have a 1-1/2 H.P. Bridgeport that wouldn't go in to neutral at all and is hard to put in high. Any suggestions ???

D. Ross Hard to pin down remotely, and not sure what you mean by hard to put into high, but a couple thoughts. The hi/lo shift lever may have loosened on the shaft and moved. It is a friction fit and clamped to the shaft by two cap screws. There is also an adjustment for the hi and neutral "index holes" under the lever (where the pin goes in). It is a sliding plate that fits into the larger mounting plate under the lever. It is secured by a set screw that comes in from the front. You can loosen the set screw and then slide the plate up and down to adjust the high engagement spot. This will also move the notch for neutral. Normally this will come loose which will cause high to not stay engaged, as the adjustment slide has dropped too far down. This can have the effect of making the neutral spot too close to low also (or the sliding part may be missing entirely). The only other thing I can think of is the back-gear bearing collar/sleeve itself (as seen in the video) is binding somehow, but that is pretty unlikely...
