Auto quill feed problem on my Bridgeport
Bernd:
Ah John, one of us must have read the others mind. I'm going to make a puller to pull the bushing out. I'm going to try and save the bushing and get it out without tapping in though. You forgot to tell me that there are two, yes two, set (grub) screws that hold the bushing in.
The spring should be fine once I loosen up the threaded screw that adjusts it for tension.
Your comment about it only being able to handle a 3/8" drill would make sense due to the smallness of that drive pin. I don't think the drive was designed to use as a drilling mechanism. It is supposed to be used with a boring head so you have a constant feed rate.
Who ever had this machine from the time it left Kodak in Rochester to the time I got probably had no idea you couldn't use the feed to drill large holes.

Thanks for the vote of confidence. The first two I have, but to be up and running by Sunday, I don't think so. The SWMBO has told me I need to get that pantry in the kitchen done or else I'll get a :whip: and a :wack: and a :zap: if I don't. So it might be a few Sundays before I get up and running again. :(
Regards,
Bernd

Well Eric must know me to well be now. :) I made a puller today and removed the bushing.
I know I said I needed to work on the kitchen pantry. Well I did, but did you know wood glue takes a while to dry. :clap:
Here's a pic of the puller I made. It's made from a piece of brass coated steel. I turned down the end to the inside diameter of the worm gear. Then I made a grove in it to a diameter of 5/32". Drilled and tapped the end for a 1/4-20 scrrew. Then I made a "U" shaped washer to fit the grove. The rod is 3/8" dia.
Here it is assembled in the housing. Not much to see.
Here is the bushing, U washer, pull rod and screw. Worked great.
And here's a pic of the whole assembly. Notice the hole in the worm wheel were the pin goes.
Now all I need to do is make a pin and reassemble.
Eric, you may be right. I might have it back together before Sunday. :D
