Sb Fourteen-hit A Snag

[Kroll]

Thanks guys,reading ya'll post and talking about it I see that really there are several ways to make a hole repairs which its nice to have choices.If I may borrow Brians ideal and chuck up the gear and put a dial indicator on it and just see how it goes.If I'm able to get it lined up then will proceeded to bore just to clean it up.Next make a new bushing to fit the bore what ever size that maybe.Either way this problem is a learning experience about the materials,reamers,just plain ole machining.Been watching Youtubes on reamers so now I kinda understand there is a place for them even in my hobby type shop on a as need bases.I really like the ideal of reaming a hole to become a press fit,slip fit,like a hole for one of those oil hole covers.Guys I won't be making those repairs for afew days,I have so much of the lathe laying around I want to get it put back together as far as I can go then concentrate on the repairs.Thanks so much for all the help and keeping it simple for someone like myself so that I understand.Progress is being made ---kroll

Guys my Colchester is kinda tied up with the hand wheel project.So I am using my Atlas lathe to bored out the gear with the help of WreckWreck and it now has a good smooth finish.So I remove my big chuck and installed my small Atlas chuck.Now I am ready to start on the bushing,using a piece of steel that was part of a care package that someone give to me I am now ready to start on it,till I get to needing a reamer for that perfect smooth fit.Can you see the bushing in my scrap piece of steel?Back to being positive ---kroll

You should be able to complete the job with the boring bar. Just sneek up to your dimension.

Chuck I did take your advice and sneek up on the OD.If I paid myself bout 5.00 hr I still would be way to expensive cause it took awhile to fit the OD to the bore of the gear.But so far I am happy with it,I did drill out the bushing for the bolt that has an OD .490 so I will take a reamer and do a clean up cut to size.So far so good but not out of the woods yet----kroll

It appears that your gear has a chipped tooth.

It does and it matches a 4 jaw chuck,not mine.Every 15 teeth there is a small chip,so someone has work on this lathe before.But other than that all the other teeth look very good on that gear,and the teeth look goood on all the other gears also.I don't think this lathe was use that much,which it did come from a school district---kroll

If that's the only damage the students did you're in good shape. The ways usually don't have much wear on school machines. Sometimes they're kind of nicked up. I had a logan 10" that came from a school. I have never seen so many broken gears on one machine. After all the repairs were done it was a pretty nice machine.

Good afternoon guys,I have good news.My snag is no longer a snag,I am one happy camper.Guys I got home this afternoon and check my mail,the reamer that I order had come in which it has an OD of .495 which will allow the bolt to be a slip fit I guess.Anyway so off to the shop to ream out the hole and see if the bolt will fit or not,and I be dang it fits and no wiggle at all.Once I flip the part around to use my parting tool for the first time for me,it went pretty well.I did take couple little five min breaks to give all a chance to cool down.Using oil on the parting it also went well just pop right off and smooth.I did allow to face to a finish thickness which had to remove another .035.So guys I finally made something that had to fit no if/ands/buts it just fit,the finish is not fantastic but smooth to the touch and the edges are razor sharp.So now I can move on to my next hurdle which will be the knob for adjusting the reeves pulley and doing all the electrical so hope that goes well.One day guys I will learn how to post pics and explain each pic.Thanks for looking ---kroll
