Hi
I would not use direct coupling Motor/Ballscrew use belt and pully, Dean always recommends this setup to reduce resonance.
Regards
Mike

I have no idea who Dean is, but if you mean rigid coupling then I agree, that should not be used, but the lovejoy couplers are not rigid.



They offer some flexibility, but not as much as the crappy Chinese sold as flexible couplers. These are the ones I mean should be avoided because they generate vibrations and can snap off any time.



On the other hand, these require less installation accuracy, so if you are sloppy, or not good at adjusting and aligning then the lovejoy type isn't the one for you.

I have no idea who Dean is,

That would be me but Mike's comment wasn't aimed at you or your comment about Oldham couplers so why you would feel the need to respond like that I've no idea.?

Not that easy to figure out who he aimed at, is it? Especially since his post is directly under mine, with no quote... So why you take my answer the way you did, I have no idea.

Yes it is Mike was talking to Rob the OP who knows me by name. He clearly wasn't directing it at you or questioning your suggestion but merely reminding Rob what had been said to him by me. Which Rob acknowledged two posts later and before you felt the need to reply.! . . Hence why I wondered why you replyed in the manner you did.

Good Evening Guys

Thank you very much for the replies. I didn't know about the other type of couplers and so Thank you. Although Because I will go with the Pulleys then it will be changeable on the speeds and torque (Although thats another learning curve for the maths )

Thanks dean Yes your right Its the problem when I get started I buy and then it sits there waiting for me for ages and I would have been better to learn and then buy after so thank you very much for slowing me down. Although where were you when I brought my AC cobra replica . still not bad that's only sat there for 7 years i'm sure they get better with age well that's if it worked.

I will got through the Logs and start to learn and do it properly I didn't really know where to start so the thread is great with the suggestions on the items that are best to look towards.

I have just come in from the Garage and still working on the frame although that is looking a bit more than box section now but only just.

I didn't have your details previously dean but if you don't mind me speaking to you at some stage when you have a minute it would be gratefully received.

Thank you all as usual for all the help you give

Thanks

Rob

Speak to so many people I forget who just seem to think I'd spoke to you some time ago.? But could easily be some other Rob.!!

I'll PM you my number.

Hey Dean

Brilliant Thank you that will be great. We've only spoken on the forum so it must have been another Rob.

What "manner"... you mean saying "I don't know who Dean is..." if that is a "manner" for you then you you seem to be awfully oversensitive, especially considering you don't have a signature which includes "Dean" so it is pretty hard to guess.

By the way, if you are asking me about why I am answering to a post which was not addressed to me, then ask yourself the same question. Especially considering that in my case it was OBVIOUS that I was not talking to you but to Mekanik, since I quoted him. So, relax and try keep yourself to relevant facts instead of this. Did I say something which was incorrect then feel free to address that, even if I was not talking to you. I really don't mind...

[JAZZCNC]

What "manner"... you mean saying "I don't know who Dean is..." if that is a "manner" for you then you you seem to be awfully oversensitive

The Manner I referred to was you feeling the need to exercise your Ego and reply to post that clearly wasn't aimed at you or questioning you in any way.! . . So who's the sensitive one.?

My reply was aimed directly at you to make clear who Dean was. However like you I don't really give shit so lets leave Rob's Thread to mature.!

Could you please enlighten me and others about HOW to check that post #9 is NOT aimed as an answer to post #8? I would like to learn something, which seems to be a secret knowledge only YOU (apart possibly from the site admin) have. If you could help me out on this I would be so grateful and would not make such a horrible mistake next time.

Yes, your reply was aimed at me, that was pretty clear to me, just like my reply to to Mike (post#13 )was pretty clearly aimed at Mike and NOT you, yet you keep debating about it and demonstrate how hurt you were because of the "I have no idea who Dean is" comment. So it seems like you want to apply your own rules, which is pretty amusing.

Other than that, for your information, this is a public forum, so if you want private conversations with your friends do it in private. It is perfectly fine, and as far as I know, not against the rules to comment ANY post on a public forum, EVEN if a post would clearly not being aimed at a person commenting. On the other hand, normally there is a rule about staying on topic and not hijacking threads, which you actually don't really follow, since you got derailed pretty fast and NOT posted one single remark about the topic discussed by me in that message to Mike. The topic there was NOT "I have no idea who Dean is" but the couplers, advantages/disadvantages and resonance.

Have a nice weekend.
