Todays Problem To Deal With..

admin

My boss told me yesterday..."Open this box in the morning and reweld the bad journal when you get in".."They think something's wrong with it"..OK no problem..I took the top of the shipping crate this A.M. and I think I found the problem..One whack with a hammer and this happened..So now we take the tube..Put the bad end in the chuck and hold it by the inside..Indicate the rubber to zero..And start stripping the rubber off the end that needs attention..More stripping..What a mess..Next!...zap!Last edited by zapster; 01-11-2008 at 05:04 PM.I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Now that we got to the steel tube turn a nice shiney spot for the steady rest and set the steady rest up before you flip it end for end..That way there the tube runs perfect for boring..Cut off some new heads from an old roller..Recycle!Head installed and ready for welding (.015 shrink fit)Not much tube wall thickness..There all welded..Let cool overnite and I'll continue with the repair tomorrow..I get all the fun jobs.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:"They think there's something wrong with it?"       Now -THAT'S- an understatement.zap:  Hey boss, I think I found the problem with that roller.boss: Yeah?  What is it?zap:  It's broke.

Reply:Hey Zap,the roller in this thread and the aluminum one from a previous post, are they something from the printing industry? I fixed alot of rollers that look alot like that at my last job. They always had alot of nasty stuff on them.
Reply:We get these from the rubber coater..The aluminum one was used in material handling..will be rubber coated again..This one is on a glue pressure line..I'm guessing plywood..There is glue all over the other end..I'll post more as we go on tomorrow..I'll show ya the glue..We only strip off what we need to do the job..This roller will be final stripped and re coated by the customer.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:There is nothing wrong with the roller in the first pic, all you need is an offset bearing block.Disclaimer; "I am just an a$$hole welder, don't take it personally ."

Reply:What is that?? Steady rest? I'm confused.

Reply:OK..Steady Rest info time..Along with finishing the job..Here is the steady rest I'M using..8" hole..65 LBS..First thing is to put the end you just worked on into the chuck and indicate the roller(whats left) in to zero..The new journal will be running out..sorta like a cam lobe..Then turn a spot on the shaft for the steady rest..No specific size just make it round..This part sucks..Now take the steady rest and slide it under the roller without pinching your fingers.. Stand it up and adjust so the bottom pads hit the shaft..The paper is a old sanding belt..That way there is no metal to metal contact and the paper holds the spindle oil so there is very little friction..Next post.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Zap, what supports the other end of the roller( not in chuck) while you are doing this ?I always wanted to be a machinist when I was younger...
Reply:After setting up the steady rest take the roller out and don't touch the adjustment..Just unbolt it and slide it to the other end of the machine..Hint!Use a old brass bushing with a piece missing out of it so you dont get chuck teeth marks on the shaft..Indicate the journal to zero..With the roller journal supported on the rest centerdrill the end..Now face it off to length..Re centerdrill and add the lathe center..Reverse the Steady Rest "install" procedure and now turn the journal to size..Next!...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Here it is all done..And thats how it works..Turned 1.999 O.D. for a 2" bearing..I get all the fun jobs.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Ahhh, I see...the steady rest is only necessary until you locate the lathe center...Ahhhh. Nice work Zap, always a pleasure to read your posts

Reply:When you're finished, do you check run out on both journals to ensure that everything is concentric ?Now that I think about it I guess a check isn't necessary because the method ensures it.Last edited by Tinbasher; 01-12-2008 at 11:19 AM.

Reply:Zap great thread, you make it look easy. Your weld look excellent, shame to turn the down.
Reply:New to the site, looks like a fine repair.Good tips on the lathe work also.
Reply:Thanks Zap i get it.We have a few of those at school , we never use them though because we never work with anything long. The sand paper is a good idea because if your dont use that you will get a lot of friction. I was told before you had to keep coolant on it at all times.
