I don't understand driving the spindle down with a drawbar? How can a drawbar screw into the spindle with no collet installed? Would like to see a pic of this spindle arrangement. Same 7/16-20 tpi drawbar used for both collet and spindle? Thanks!
You are not screwing the drawbar into anything while doing this procedure. The drawbar is acting like a long punch for the spindle. If you have more questions you can give us a call 1-800-285-5271
I'm working on a Prototrak DPM3 that has a head modeled after the Bridgeport 2J, and given that it is a 3-axis CNC I have a hard time thinking of a case where I would need to use the power downfeed. I'm always interested in finding ways to tidy machines up, and so it got me wondering if all the hardware associated with the power downfeed could be removed and whether the head would continue working well otherwise without it.
I've been watching your videos for a few weeks now. I'm in the process of repairing my step pulley J head. In appreciation for all your help - I decided to buy my parts from you. Thanks for your great videos. 👍
A trick for getting the blind bearing out. Pack its hollow shaft with grease and reinsert the bull gear shaft. Try to seat it with an arbor, press, clamp, etc. The hydraulic force should push the bearing out.
I will have to say H&W is a pleasure to work with called for some parts ( a few times) they knew what I needed before I finished my sentence. Great company and not cheep knock off parts highly recommend
Love watching the internals and how they work had mine apart have used you guys for all my parts !!! Great always right the first time !!! Thanks be looking forward to the esembly
H&W is a great company! Barry is the “bomb!” I called customer support and Barry got me up and running again with answers to my questions. I am amazed how helpful they are! Thanks very much!!!
Interesting about that wheel handle for the quill. My Bridgeport Series II Special has the exact same wheel on it. I found I really like it and how it never bashes me in the head. 😀 I thought mine was unique, but after seeing it on that machine, it makes me wonder if it wasn't some aftermarket product or something that went around on some BBS back in the day.
Does anyone know the correct number of links in the speed adjust chain? I'm asking because the lowest spindle speed my machine will adjust to is 154 RPM, with the speed dial indicating that the lowest speed in low range should be 60RPM. Causing me to suspect that the chain may be too long, preventing the rocker plate from pulling the top half of the front pully down far enough to achieve minimum speed.
Because of this channel I completely over hauled our barely used ‘73 Bridgeport. I never knew I would have such interest in restoring machines like this. Thank you H&W!
How did u know I needed that. Tried to use this Jet, Bridgeport knock off & the lever wouldn't engage. I searched H&W m/c repair & boom, this is the first video. Thanks Barry.
arg, you stopped before the downfeed clutch! :) how to adjust it, what to adjust it to, and how to _set_ that, and what to do if it won't hold 200lbs even when the spring is maxed out..... :)
If you look in the description box I posted two other videos that kind of go into that. Let me know if you have any other questions or give us a call and we can walk though it over the phone: 1-800-285-5271
