I have a Delta Drill Press. It is not really OLD iron; it is younger than my car. On the other hand the car acts like new and the Jacobs Chuck on the DP gets very difficult to adjust.
Twice in the past I have cleaned the chuck with mineral spirits. This makes the chuck work fine for a couple months and then it starts acting like I put chewing gum in it.
This time I removed the chuck and soaked it for a few hours in Klean Strip “Industiral Maintenance Coating Thinner provides good solvency and can be used in place of MEK, Toluene, Xylene and VM&P Naptha for thinning Industrial Maintenance Coatings.”
I did this because I did not want Royal Clark to be the only one who jumped into something before he had all of the answers. Anyway, did I do good, bad or indifferent with my choice of cleaner?
The procedure I used this time: Put the chuck in a can and covered it with the fluid. Let it soak a couple hours. Then every time I thought of it I would flip the DP switch and let it run for an honest 15 to 20 seconds. Part of the time I did this with the jaws wide open, sometimes with the jaws half way and sometime with them almost closed.
After each “swirl” I let the chuck drain a few seconds.
QUESTION: What should I do now?
Thanks in advance.
My dad purchased a Delta DP back in the late 40’s or 50’s. It got a lot of use between my dad and me. The chuck was still working perfectly when I sold it 4-6 years ago.
