machine height?

[shamefowjze]

i've been looking throught the adjustment section of the manual and i have yet to see an actual "measurement" for the height of the machine. the reason i ask is this. we had synthetics installed about 1 1/2 years ago and all of the tables were raised. well they are all good in realation to the pindeck, however alot of the tables now rub against the shuttle. is there a measurement i should be looking for or is it just raise the machine on the jackscrews, then adjust the tabledrive link til the table is good in both positions?

thanks

Alex....just raise the shuttle by the adjusting rods on the rear. 9/16 wrench and ratchet. Just take the spring off with no pins in the shuttle. Move it back and forth until no contact with the table at 0.

Re: machine height?

There is a correct height. Crud can tell you more about it than I can. He has all this stuff locked in his brain. I am slowly raising all of my machines for the same reason. I believe the measurement you want is 19 1/2" or so from the pindeck to the bottom of the machine frame at the jackscrews. Just raising the shuttle might create other problems. I will try to look at my prints and make sure this is a correct measurement for you, but if Crud sees this he will let you know.

Re: machine height?

We used to set the top of the leveling nut at 19 ¼” off the pindeck. This would be the same measurement to the bottom of the frame weldment.
This is also about 489 mm.

Re: machine height?

I like to leave the front end a little lower then the original measurement AMF said it should be that was 35-3/8 to the bottom of the cross frame where the u bolts nuts are for the sweep from the top of the pin deck.I set them at 18-3/4 from the top of the pin deck to the bottom of the frame in all four corners.leaving the front end a little lower stops the double shuttling :p .
the other problem you could run into is you raise the front end say 1/2" and you may not be able to get the bolts back in that bolt front end to back end [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] then you would have to raise the backend and those frozen jack screws are fun to turn sometimes [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]
it all depends on how the machine were originally installed.CRUD [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]

Re: machine height?

jer,

the shuttle thing has already been done. the one problem that i forgot to mention was that the cups are hitting the tops of the pins when it comes down to feel for pins. so it keeps knocking pins over. thanks for all of your replies.

Re: machine height?

i set all my machine heights to 19", do you have adjustable table legs or the fixed kind, as a rule unless your pindeck is sloped, with the fixed leg, no spacers are required, and with the adjustable legs i have 8mm of thread showing at the top of the nut.

works fine for me !!!

i have found after flagging the table at this stage, and running through my table adjustments, that the last i hear of tables running a drift.

hope this helps

Re: machine height?

It is possible the mechanic before you new what he/she was doing and lowered the shuttle over the years. Still it wouldn't hurt to check the hight of the frame and old style table legs if you got them.

PS. I didn't realize the toilet was white until after I hired her. :p

Re: machine height?

Just a thought. If you raise the shuttle to its highest point at present and you cannot go up anymore you can raise your bin and then it will allow you more clearence to raise your shuttle a bit more.

Re: machine height?

ok i raised one of our problem machines. it was almost 3/4" too low [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] .if i had to put another washer in there i would have had to raise the elevator. i've never had a problem with double shuttling at this center however i do have head pins that love to fall through the bin when they're not suppose to. i've tried lowering the head pin rails but it hasn't seemed to help. kinda lost on that one. but thanks for the replies on raiseing the machines.

Re: machine height?

You can fix the head pin d/s by re-drilling the head pin rails and lowering the end next to the 5 pin. Lane 11 had a prob. like that. Lowered it....no more #1 double shuttles.

Re: machine height?

Its best to raise them in pairs if you have the time. Also, are you talking about the pin elevator or the ball elevator?

Re: machine height?

mr. 800 i tried drilling new holes in the rails and lowering it on the rear side but it hasn't made much of a difference. i thought about moving the shuttle backa little more to see if that might cure the problem.

jimmy jam i was referring to the kickback section that bolts to the machine frame. if i neeeded to raise the frame any further i would have had to raise that part of the machine as well.

Re: machine height?

there is a correct "measurement" for table,shuttle height ,but that is for a "brand new 82/70" raise the table so it is spotting fine then adjust the shuttle to meet the table adjustment in your case raise the shuttle to the table adjustments put pins seated in the cups anh the table @zero the bin pins need to be raised aprox. 1/4" to 3/8" this will prevent any double shuttling and crap

Re: machine height?

Don't forget to raise the distributer.
