So, botched the screw removal from yesterday. What are my options now?

plshelpme · Jul 17, 2017

Pictures. So pissed off. I think it didnt help that I wasnt perfectly on center, but mostly it was that the fluted screw extractor was apparently larger than the damn hole. Can I do anything anymore or am I pretty SOL? Should I try to buy some new screws and just test it? You guys were amazingly helpful with your suggestions the other day so I figured I'd try again to see if I can save myself lol. Thanks for any advice! :eyecrazy:

Drill, tap, helicoil?

APEowner · Jul 17, 2017

It looks like it's time for a helicoil or other thread insert.

turtleman321 · Jul 17, 2017

Time-Sert threaded insert.

Dont waste your time with Helicoils.

plshelpme · Jul 17, 2017

How much am I looking at for this type of repair (helicoil/time-sert)? I can get a new used piece for $50 or so. $210 new, no way lol.

ItsNemo · Jul 17, 2017

$50? Replace it.

LX-Markham · Jul 17, 2017

what is it, by the way?

Yeah, if you can replace the part with the botched screw hole for $50, I'd go that route.

Commercial coffee grinder. I dont really need it and dont want to spend money on it to be honest. Thats why the extra $50 (probably like $75 after taxes and shipping) isnt something I necessarily wanna spend haha. I mean, it'd still be a good deal but not as good of a deal. So i figured if there's a cheap fix I'd try that first.

58Yeoman · Jul 17, 2017

If you have a tap & die set, try tapping it and see if a bolt will hold it. Would be much cheaper to try that route.

Or, if that doesn't work, try JB Weld, redrill and tap.

I'm pretty bad with anything related to fasteners. What would be the difference between a bolt and a screw in this application? I know I cant go through the back (as far as I can tell) and put a nut on it, thats for sure. I think i've got a friend with a tap and die set.

Got it.

Then yeah, it's a great excuse to buy yourself a drill and a tap
....or find a buddy that has a set.

plshelpme · Jul 17, 2017

Question: just to make sure, I need an SAE tap set right?

ard · Jul 17, 2017

Can you use a larger screw? upsize the hole, nice and clean- fresh tap- wa la!

PAToyota · Jul 17, 2017

Ouch… I’d be inclined to weld it up, drill, and retap at this point.

plshelpme said:

That would have been a bolt that threaded into the threads in the hole - therefore not needing a nut.

Rickss96 · Jul 17, 2017

A bolt typically has a nut on the end to tighten things up. A "machine" screw threads into a blind hole. Thats what you have. And to most of us, a bolt and a machine screw are the same. Then there are machine screws and wood screws which look different.

plshelpme said:
Question: I need an SAE tap set right?

If it is an older made-in-USA machine then it is almost certainly SAE. To be sure take the screw/bolt from the other side and go to a decent hardware store that stocks a lot of nuts and bolts. They will usually have a thread measuring tool you can use. Our local Home Depots have one hanging right there. If no tool is there just keep trying different nuts until you find one that threads on easily. Or try an ACE hardware they can usually do it for you.

Plastikosmd · Jul 17, 2017

Where are u located
Maybe there is one of us near that drill out or mig a nut onto it

Ole Slewfoot · Jul 17, 2017

Or put the burr in with one screw and anarobic adhesive.

dadsEH · Jul 17, 2017

JB Weld........someone had to say it... :lol_hitti

LXCam · Jul 17, 2017

Fill it with liquid metal then drill and tap another hold down location. The diagram makes that look very possible. Do you got a picture of the part that bolts in?

619DioFan · Jul 17, 2017

The upper area of the hole does look rather gouged open. can't tell if the threaded part lower is damaged. I would try these step first-

1 - get a new bolt/screw of the same size of the original and try it.
2 - if the oe size bolt doesn't tighten up then use a tap one size larger then use the next size up bolt/screw
3 - if this doesn't work then drill and install new threads ( helicoil is what I use as timeserts are a little pricey for my blood )

FYI - If you post your location one of us may be near enough and have what is needed to help you out.

plshelpme · Jul 17, 2017

Well, the new screw wont go in the damaged hole at all (as expected). There are no threads I can see. If i'm gonna be honest I think that i can just re-tap it and it would work fine. I'm gonna buy the tools i need and go for it when I get time. No harm if I try the same size, right? Should I drill it clean or would the tap go in fine as is? May be (is) misguided, but I kinda think the extra metal from the still-kind-of-in-there screw may help haha.

If that doesnt work, I'll try a size up (dunno yet what that is)...that should do the trick and I think would work fine with the burr. The helicoil thing sounds ****** awesome (youtube videos left me in awe; had no damn idea that was a thing), but I dont know if I possess the skill to do that.

Lastly, I'm in the midwest if any of you metal magicians wanna try your hand and help me out lol.

Edit: for those requesting images, here are a few I found online that kinda sorta maybe show what I'm working with. I'm taking everything apart so I'll be able to get more images and info later.

And even better explanation..... "1 - get a new bolt/screw of the same size of the original and try it.
2 - if the oe size bolt doesn't tighten up then use a tap one size larger then use the next size up bolt/screw"

And don't buy a 4cent low grade screw, but something harder better steel, like out of the tiny Hillman drawers at the Old School Hardware store, sold by each.

Hex head socket cap screw ( used w Allen wrench) would be great, unless there is head clearance space problem.

Simplest way by far, unless there is a problem w a larger screw. Marc

Like these....

matt_i · Jul 17, 2017

If you are in SE Michigan I can help. Bring it over and I'll fix it while you wait. What I would attempt to do is figure out what size bolt or screw was previously used, and then drill & tap the next larger size in the same thread system (SAE or metric) on both sides. That's guessing or assuming the larger size fastener + the larger hex or socket would work with the piece that connects to it.

Before you stuff it up completely.... how about a pic oc the current situation. This is like doing heart surgery with a blindfold. Are you just winding people up in here or what???

firebirdparts · Jul 18, 2017

You guys giving advice need to back up and give advice like you're giving it to somebody who doesn't know what a bolt and a screw is. A lot of extremely basic questions have not been asked.

The first question you need to ask what would happen to the coffee grinder if this bolt was not holding it together. It might still work. If it is needed, then you need to consider whether you can access the back side of it to put a nut on it. Both of these questions could stop the work.

Third, if you do need to tap this hole, then recognize that you are tapping the hole and you are buying the new bolt. You get to choose. Don't ask us how big it is. You choose. The hole and the bolt should match. For any thread size you choose, there is a rule for how big a hole you drill. In this situation you want to consider that.

4th, be warned there is some skill involved in controlling a tap when you are working with no tools and no machinery. It is not all that easy, but it is possible.

Marctrees · Jul 18, 2017

RE: Pictures..

OP Post #1 has a link to pictures, but it's really easy to not notice it.

The first word in post..... "Pictures"..... is linked.

Past that, I just don't want to see pictures of a snapped off tap in a hole. Marc

lilredex · Jul 18, 2017

Did you guys recommending the "Time Sert" route check out the video and cost of that kit? For one size hole repair...$68

https://www.amazon.com/dp/B0025MQ63Q/?tag=atomicindus08-20

I have a 5/16" threaded hole in aluminum that needs repairing, but I think I'll pass on that one.

plshelpme · Jul 18, 2017

Unfortunately I'm not in michigan! I was a couple weeks ago though haha. Thanks for the offer.

Haha, I swear I have been posting pics along the way. Maybe not the best pics but I have posted them. I do know the difference between a screw and a bolt, but to me this sucker looks like a screw and acts like a screw, not a bolt. I have used all sorts of screws and bolts before. I was not aware that a machine screw is considered a bolt.

Time sert looks even cooler than helicoil but damn...it's expensive. And why is it unusual that I'd know a person with a tap and die set? I think I know several. I will probably just end up getting it myself since it seems like a good thing to have. I dont have any experience with machining or working with metal, thats for damn sure. I think I've answered this previously but...(until i get the chance to take it apart I wont know for sure) there's no way I can drill all the way through and secure it with a nut.

I asked what the next size up is because I have no idea what the actual next size up is. I guess I can google around. If that is too large (theres not too much room, that I can see) it wont work. It may actually just work fine with one screw but I dont want to try it. I have a feeling that it would eventually come loose which would just destroy several hundred bucks worth of burrs instantly. I dont know if I trust myself to use a tap and die (or use it correctly anyway) so you've got me there lol.

I guarantee I'm not winding you guys up. I genuinely appreciate your replies and read and consider each one. THANK YOU!

LX-Markham · Jul 18, 2017

If the bolt (machine screw) is not holding much force, maybe something like Loctite form-a-thread might work? I've never used the stuff, but it might be easier and cheaper than going the drill and tap route if you are not set up for it.

plshelpme · Jul 18, 2017

That's an idea too. I guess I can even glue the damn thing down as well. I guess it's not the biggest deal in the world, but I'd like to do it right. Eventually that housing will hold $400 or so worth of burrs. Which while thats not an insane amount of money or anything, it is a lot for drinking drip coffee (not even espresso

).

Marctrees · Jul 18, 2017

What's with the Timesert or Helicoil hassle???

Why the heck not just drill and tap to appropriate size, now that the hole is reamed out like mad. ??????????????

Did I miss something ???

Glue it down???

$400 of burrs, a totally messed up hole, and your thinking experiment with ANY kind of "glue"?

You local ACE store sells single drill bits and matching tap in little packs, like $4 for your size range... You don't need a whole damn Machinist's Set.

VERY simple to use, once you know how.

But for your first rodeo, with apparently no metal drilling or tapping experience, you'll be snappin bits and taps.

At this point I would highly suggest to find someone familiar with this to fix it for you.

You must know a hobbyist familiar w tapping, that will fix it for you for a six pack, or Starbuck's Soy Milk Chai...... whatever's the case.

Respectfully, "A Man's got to know his limitations"

You obviously must have skills I don't, I can't afford a $400 + grinder.

But not this. Marc

Now we're talking about $400 burrs being ruined if the fix fails?

No, no, no, now I'm going back to my original recommendation of replacing the entire part with the used $50 replacement.

Another option is a rivnut

plshelpme · Jul 18, 2017

Damn guys, chill! I am obviously not gonna glue it down, I was just saying that I could probably glue it down and it'd be fine. Not that I would. A larger fastener MAY work, but may not (due to there being a hole in the burr that the screw goes through).

58Yeoman · Jul 18, 2017

Dutch01 · Jul 18, 2017

Just kill this thread :rocketwho

The OP doesn't need or want help. Lots of arguments against any good advice given :rant:

plshelpme · Jul 18, 2017

Alright, well, since you feel that I'm being argumentative (?) or dismissive (??) of your suggestions I guess I just wont reply anymore. I read back over what I wrote and couldnt find evidence of anything of that sort, but if it came off that way I guess I'm sorry. Thanks for the help!

So, botched the screw removal from yesterday. What are my options now?
