Jacobs 13268 Wedge Set Used On Jacobs Taper No. #3JT

Twenty three years ago, I put my Jacobs 3A chuck on the MT4 arbor on my then new drill press. I even warmed up the chuck in the oven and cooled off the arbor in the freezer. Then I put the two together with a solid tap of a mallet. I never really expected to take them apart again, figuring the chuck would wear out, and I'd just pitch the whole thing. Well. the arbor got all galled up over the years, but aside from a bit of rust spots, the Jacobs 3A chuck is as good as new. Considering the way I put the parts together, I knew the thing might be a little stubborn in coming apart. I tried every trick I knew, but it was like the parts were welded together. I gave up and bought these wedges, and two minutes after they were delivered, the chuck was separated from the arbor. The only thing that drives me nuts, is paying 25 bucks for something I may never need again.

I wanted these for use on a Harbor Freight 13" Bench-top Drill Press. The stock items on my drill press include an arbor with Morse Taper #2 (MT #2) and stock chuck which has a #3 Jacobs Taper (JT #3).The dimension between the tines (horizontally) fits the taper just right (about 7/8"). However, for my case and configuration more vertical movement is needed to separate the chuck from the taper.As it is, with both wedges in place (max vertical dimension) there is still a slight gap between the highest point on the wedges and the contact point on the taper making this solution not applicable. i.e. two wedges did not deliver enough vertical displacement needed to separate the chuck from the arbor ... it was close but another set of these (actually one more wedge) would do the trick.In the past I had been using a 12" length of hardwood (a scrap of black walnut actually) and a light mallet to remove the chuck by tapping on it from a sharp downward angle adjacent to the quill. Unhappily, this method can not only dislodge the chuck it can also dislodge the taper (with the chuck still attached). Wedges really are the right way to go because they work to SEPARATE the two parts from EACH OTHER. Just make sure you have something like a small plastic bucket with plenty of rags in it under the chuck to catch it and prevent it from damaging itself or what it hits as it drops from the tool (with or without the taper attached : )In general the product is of decent workmanship and material quality and I would recommend this product. My solution is in progress ... this will be to either cut a section out of a large washer to use as a vertical spacer or simply buy another set of these wedges which seems like the easiest solution given the time and effort needed to manufacture a spacer versus the relatively low cost of this otherwise fine product.

Worked well. Youtube videos show hitting with hammer but I used a short pipe clamp and that gave me much better control with a gradual squeezing.

Been trying to get the Jacob Chuck of a Ridgid Drill Press. Tried tapping, per the manual, and then hitting the chuck...no joy. Used flat tipped screwdrivers per some forums...no joy. Got the wedges in and within 30 seconds had the chuck off. The right tool for the job.

It took some grinding to get these shims to fit around the shaft to drive off the chuck. It worked, and would work again, but not for regular use.

The pictures showed this was for a #6, but what I received was definitely for a #3 as I ordered. These appear well made in the US by Jacobs (Apex Tool). Couldn't be happier.

I ordered #6 wedges as shown, I received #3 wedges. I was able to use them as they were bigger. To much trouble to send them back and reorder. Someone screwed up the description, something is miss marked.

This product will only work, maybe, for 1 in 6 setups. on my drill press, i had to shim the wedges and then it removed the mt3 arbor with the chuck still attached. After trying other ways, i thought, heat. A little heat (not much) to the chuck and it dropped right off, wedges never needed. The only way this will work 100% as it should, is if the jacobs taper is built into the spindle and the chuck fits close to the spindle. They are wide enough to clear the jacobs taper anything above that, you are on your own. If i have to make my own shims to make these work, why do i need them ????????? Don't be lazy like me, make your own custom fit wedges. One needs to be narrower then the other for most setups anyway.

Dont believe the picture you will receive the good part with 3 written on it

Took a ton of abuse and did the job. Survived a real beating!!

Product is used to wedge off a chuck from the shaft. Works as expected.

Worked like a charm after struggling to remove chucks. This makes it easy. Great price and i will have them forever.Very satisfied.

They worked great on the chuck with the Morse taper 3 but the wedges are too big for the Morse taper 2.
