Hi guys! I finally got my wide makerslide after the package sat in my local post office for over a week due to the label falling off. Luckily inventables customer service was able to track it down and had the post office send it out to me.
Now, during assembly I found that the threads in the makerslide weren’t cut straight due to the open slot where the bolt holes were extruded. Due to this, many of the holes only have a couple of cut threads on the solid section of the hole. I assembled nonetheless, but didn’t fully torque these screws due to fear of stripping. Would you guys see this angled thread cut and poor engagement on the solid side as something to be concerned about in the long run?
Phil, I know your intentions are probably always the best, but you sure come off demeaning in many of your responses. This picture is PRE assembly and what you are seeing (despite trying to blame this on me) is what was recieved from the factory. Screws went into them very easily and they definitely didn’t crossthread. Due to the partially open hole that I assume is to facilitate extrusion, the tap went the path of least resistance and started working towards the slot away from the solid material opposite the slot. I imagine there will be a lot of customers that see similar angled threads. Is it an issue? I guess only time will tell. As mentioned though, I am at least somewhat concerned about torquing to an acceptable spec for fear of stripping these threads.
Intentional or not, you have a certain way with words…
I didn’t explicitly state that this came this way from the factory, but alluded to this idea by saying that the threads weren’t cut straight(on an item that is sold with threaded ends).
So, back to the purpose of this post. Would this open hole design be considered structurally sound in a the long run? If ones new wide makerslide had this same condition, would the screws not biting into the sold back portion of the hole reduce its holding strength (my assumption is yes)? If, for whatever reason, someone were to disassemble and reassemble several times, would the hole slowly open up with repeated torquing rendering the holding capacity diminished? I don’t imagine this is the “best” design, but maybe for its intended purposes it is adequate.
Yes Ill try to take a picture tomorrow. The alignment didn’t seem like it was too far off, it was just the lack of full thread engagement that I was concerned about.
I agree with you. It sounded like phil was blaming you. Anyway to me this does not look good. Why should you have to modify something that is new. Call up inventables and ask them. I myself would not use it. You don’t buy new clothes to have them altered to fit.
Nothing wrong with that. Just tide all three screws first, and tide the bad one last. It will straight up the bad thread. Just go slow, also very good idea if you use a little WD40.
What if you cleaned it up and retapped it with a M6? The walls look pretty thick. I haven’t received mine yet so I’m not sure if I’m talking out my a$$ or not lol. But that would be a simple fix.
Wow phil that’s a night and day difference. There must have been an issue with the process on my batch. I’ll reach out to customer service and see what they say.
Curtis, I did toy with the idea of trying to re tap the hole albeit with another M5 tap. With the slot in the hole, It doesnt seem that there is any way to hand tap the hole with a standard tap. The flutes (three flute) of the tap get caught in the slot . I really dont know how they tap the hole without it walking out the slot. I guess in my case, they didnt…
Hey Phil did not mean to make you mad. I was just meaning that the way the wording was it sounded like you were blaming him not the company. Like i go to my sisters house and say it looks like a tornado went through here. Does not state how it got that way just that it is that way and I am sure that was all your meaning was, like man that is so bad it looks like you cross threaded it really bad. Not meaning he did it but that it was done somewhere.
Just as you said you can not interpret typing. The meaning can be totally different then it sounds. You have a lot of great posts here and everyone including myself appreciate it so please accept my apology.
I have been in the tool & die business for more than 48 years.
I know what a tapped hole should look like.
Just look at the difference in the end view of your part vs the end view of Phil’s part. (it looks like yours was cut off, (shiny) while Phil’s part has e-coat on the end surface)
It is probably a machine tryout part that accidently got though the QA system.
Trust me. That part is defective.
@JanVanderlinden thank you for weeding through the references to genitalia and posting. Your feedback is much appreciated. As someone who has experience with tooling, do you think threading these slotted holes is an adequate long term solution if they are properly threaded?
A better idea to begin with would be to give Inventables a shout and give them the opportunity to make it right with a new part. If you attempt to correct it that option may go up the dust collector hose to “not gonna happen” land.
