Reed 105 Question

[ToolSteel]

A few days ago, I bought a Reed 105 for $150. I'm just now trying to take it apart.
The dynamic jaw moves with the aid of a collar and set screw. I've removed the set screw, but can't seem to get the collar to slide down the spindle. I'm reluctant to use too much force to break it free. Any suggestions?

P.S. As should be obvious, I'm not very skilled when it comes to attaching images. I hope to get better.

The set screw may have scored the shaft.
You may have to gently pry the collar down the shaft until you get past that point.

nice vise,when you get it cleaned up it will give you years of service.

Jake,
The set screw was very hard to back out... and both edges of the collar are mushroomed a wee bit, so it looks like it's taken some abuse. I tried to wedge it with a big old screwdriver, but I was unsure about how much torque the dynamic jaw could take. I'll take my time and try to pop it free. Thanks for the tip.

File the burrs off if you see any, use a block of wood or like I use which is a piece of copper or brass and drive the threaded spindle past the collar from the rear of the dynamic jaw support. Once the collar is past the burrs it will slide off. The collar sets your backlash so with shims or reversing the collar you can tighten it up so when you back out the dynamic you do not have to spin a 1/2 turn or more. Good luck.

KMScott,
Thanks for the advice. I'm trying my best to follow it, but I'm a little hazy about the geometry involved. I put a small copper blank between the collar and the inside body of the dynamic jaw. I then placed a 2x4 against the exterior of the jaw and gave it a few good whacks with a hammer. Nothing budged but the method shows promise. Is this what you were trying to tell me?
After some adjustments to the spindle nut, I was able to remove a pin that held the nut in place. The dynamic jaw moves easily to the fully closed position. Now if only I could break the collar free.

I think he means to put a block against tha back end of the leadscrew and whack the 'screw out that way. The collar will be prevented from moving by the front jaw.

 

[ToolSteel]

Ah, that never occurred to me. Will it make any difference that part of the spindle still appears to be inside the spindle nut?

 

[Provincial]

Whacking the spindle won't do much good if it is still engaged with the nut. The advice assumes that you have removed the dynamic jaw and spindle as an assembly by unscrewing the spindle until it no longer contacts the nut. At that point, you should be able to pull the dynamic jaw assembly out of the fixed jaw. With it on the bench, you should be able to remove the spindle by tapping on the back end of the screw, driving it through the collar and out the front of the dynamic jaw.

 

[Fretters]

Ah, that never occurred to me. Will it make any difference that part of the spindle still appears to be inside the spindle nut?

Yup. As Provincial says, you need the front jaw separated from the rear jaw first.

Reed 105 finally apart

Finally found some time today to once again tackle disassembling the Reed 105. The captive collar inside the dynamic jaw was/is giving me headaches.
After I managed to get the spindle to disengage from the threaded spindle nut, I used wooden dowels and lengths of 2x4 to hammer away at both the spindle and the dynamic jaw. As you can see, it finally popped free. The collar has definitely moved, but it's still snugly clenched around the upper spindle shaft.
I plan to put the dynamic jaw in a 4 1/2" Columbian vise of mine and pound on the end of the spindle until the inside of the jaw pushes the collar onto the spindle threads.
