Thread: Router Lift / Car Jack

Only two types i'd consider old (i'm only 40 so there's a lot of leeway on whats old or not, i didn't lookup the histories), and that would be the oil bottle jack http://megacheaphardware.com.au/imag...2012%20Ton.jpg or scissor jack http://www.diseno-art.com/images_3/scissor_jack.jpg , as opposed to the others, trolley jack http://espimages.biz/2386/I/493/2/images_020111800.jpg or the hi-lift post type http://www.extremelimitsoffroad.com....hlift1_sml.jpg or even the airbag or other assorted new variations on jacks. And i think the only one to use would possibly be the scissor. With that said its supporting a lot of vibration on an acme thread and not sure it would not unwind itself. I think i'd much rather leave it to the inaccuracies of the router itself rather than add more in mechanically, but thats me.

I use the scissor jack as my router lift. As Neal said the vibration with some of the larger bits does wind it down,To over come this I just lock the plunge, once I have the correct depth set. Works like a charm.

I use small (2 tonne) hydraulic jacks. They can be found at prices around $19 to $25 if you look long enough. These, I found, provide much finer adjustment than the coarse screw thread of scissor jacks. All I had to do was make up an extension bar from the top of the jack to the machine. Like "pal" of Bundaberg (Yeah Bundy!!! - knew it well in the early '80s), I also lock the machine in place and drop the jack support 1 or 2 mm.

Do you happen to have a photo of what you have do, or are you able to take a photo and post it om here?

Arry,
Here is a link to another use I have used 2tn hydraulic jacks for - in this case it was to precisely lift and align an in-feed table extension for my M3 Triton. You can easily see the extention tubes (made from PVC piping) and small MDF foot plates to locate the tubes onto the top of the jacks, Each MDF piece has a shallow circular indent cut into it in order to make it fit snugly onto the top of the jack stems.

This is pretty much what I do when I use them under my double router table though I don't as yet have any pictures of that set up.

I've attached a picture.

I'm pretty sure if you search long enough on the forum you'll find examples - I remember reading about the idea here ages ago.

The only flaw is because it works by pushing up on the router from underneath, you can't use the standard router mounting plates that drop into the table tops. (as far as I remember)
