A friend showed me this video. Very well made video. i watched with pleasure. I have to point out you are about a decade wrong with manufactury date.😳 This is the latest version of Primus Brockhaus made. It has the edged spindle guard. It fits on the modern swivel base. The latest version is introduced in the summer of 1957. Your Heuer Primus is end fifties or the sixties. I am not shure if the production year is already forged in the dent of the slide under the dynamic jaw. About the rough surface. It is possible the forging molds were starting to wear out and Brockhaus never replaced them when these got out of specs due to too low demand of this model. The last version had only the 150 6" and 175 7" models.
Very nice. I’m surprised more rebuilds do not include thrust bearings on the lead screw. It looks like this significantly improves clamping force. I really like the color.
would have been a better idea to place the bearing before you place the spring on the inside of the spindle. The way you did it doesn't relieve the friction.
Fabulous vise! You didn't need the rear needle bearing (but it won't hurt) - the front bearing works when you tighten the vise, the rear bearing only does anything when you're opening the vise. Very light forces so you don't really need a proper bearing. You might want to consider a shorter handle - since you've reduced the friction between the screw and the vise (with your needle bearing) you can now apply more force, possibly to the extent of breaking the vise. And a shorter handle is also easier to turn and spin! When tuning between centres, the tailstock centre is normally the hardened one, but the drive end centre is normally soft. It will not wear out, because there's no relative motion between the part and the centre. Moreover, a soft centre can be turned to a point (using the compound set at 60 degrees) which guarantees perfect concentricity, even if the spindle has runout.
the needle bearings were a great idea. using the gear puller to install the the split ring great idea.
When Germans say "ummm, we dont know when this was produced" rest assured it was produced during the war.
That's my though too. Sure were a lot of business records lost during the later days of the war.
Bondo on a vise? Really?
Rushing work..
❤💯👌

its forged steel vise you can't break it with that handle.
Well done👍
Thanks! I appreciate it.
