Did the pre-Chinese routers have that poor design too?

A bottle jack would be worse. You have no control over how far it would raise the bit. It's all about control. If you are making something like rail and stile joints they have to be so precise that you can't have one side even a hair higher or lower.
I agree about the bottle jack.



I considered that, especially using 3/8-16 rod so that each revolution is 1/16 motion. Ruled it out because it would take too long to raise very much and I would have to build the scissor mechanism.

Plan on test cutting today, will report how that goes

Thanks for y'alls input. I had ordered this scissor jack on Amazon. The 1st one they sent got lost so they sent another, which also got lost so they sent a refund. That's when I decided to use the car jack. Well, the jack came yesterday & they company said to just keep it. The concerns you all had were spot on concerning the vent holes and the difficulty in accurately adjusting using the acme threads. So, with thanks for all your recommendations, here is the revised design. Although there is space for air intake, the intent is lower the jack and pull it out out once router housing is locked, but it's not the end of the world if I forget occasionally.

We mustn't forget that wood, unlike metal moves with the weather therefor absolute accuracy is not required. To operate my lift the pedal is pressed 'till the bit is slightly higher than required then foot pressure is gently released until is the bit is at the required height. A measuring device that reads in microns is not required.

I'm not sure what you mean by "router vs the foot pedal" Using a foot pedal is not only fast, but it leaves both hands free. Another use that is super fast is doweling, once the router depth of cut is set, a quick press on the pedal and there is the hole! Unfortunately I can't find shots in my computer showing examples, I reckon that they were lost with one of the hard drive crashes
