  • Length of Travel

    I just put an Air Spring lift kit on my HF mini-mill. I also put in a new plastic drive gear which I broke because of the head falling. The Air Spring should cure that problem mostly. My question tonight is how much travel down is the head to have? My pointer on the scale on the side of the column is dead on "0" and it travels down to "6 1/2" . It seems like it is still pretty far up off the table. I don't know if I'm running out of gear rack or something else is wrong. I replaced gear rack with Spring. Anyone out there that has one of these what does your's read? I'll check on the Yahoo group also. Thanks for any info. Boot.

    I never really look at that scale, but I just went out and checked, and my travel is from 2 7/8" above the 0 mark (where I lose engagement with the rack) to 8 1/8" below the 0 mark (where it won't go any lower). So, I have about 11" of z travel.

    Is your z-stop getting in the way?

      No the Z stop is no where near it. I can't figure it out. I hate to take it all apart again. When I bump the stop at the top of the column it is right on Zero and from there down it is 6 1/2" . I don't think I ran out of the gas springs length of travel. I drilled the hole for spring 12" down the back side of the column. I'll have to climb up on top of table and look at it . Tomorrow. Too bad I already glued the columns plastic cover back on with gorilla glue. It's 8 o'clock here in NE PA and I was at it all day. Little Machine Shop said 1 hour to change it ,but I move slow and careful I guess.

          How did you put the cap back on the column? Didn't the air cylinder get in the way?

          Can you post some pictures? Sounds like your setup might be different than mine.

              I will take pictures this morning or tonight. Have to go to Big Foot show with Grandkids at 2 pm. I cut a slot in the little plastic cover in order to put it back on the top. It still has a small hole where it slips over the gas spring. I figured it would be better than nothing covering the top hole. I can't raise head to the top of column because of the stop moved from original place to new place closer to top. This was done according to LMS directions. I just can't figure out why head stops at 6 1/2"'s of travel.

                I found the new stop location to be fairly annoying, so I took it off. I haven't noticed any ill effects, so far, from extending the travel up to where the rack stops engaging, and the extra (almost) 3" is quite useful.

                You should definitely have more travel on the bottom end, though, unless they are shipping a different spring with the kit.

                  I think the cure is to drill a hole 2 1/2" below the hole at 12" mark now . It will give me an extra 2 1/2" that I need. Here's pictures if it works.

                    I'm having trouble posting the pictures. I thought I had the four of them and I ended up as you can see post the first one four time. Sorry about that.

                        How far above the workbench/bottom of the mill is the bolt in back that the spring is attached to? Mine is 11" up.
