Thanks Mike! Well it is a project that's part of my studies but this device was made by someone else and he is the one who instructed me on how to make it but since we both have different motor/fan I couldn't copy exactly what he did so I needed to figure out somethings myself. I also wanted...

ahh I understand, thank you for the explanation! Yes I might just try the locking compound, haven't thought of that so I appreciate for your helpful suggestion. I'll go look for an aluminium fan with the same shaft diameter and will try your method of using the grub screw as well! I can test out...

Thank you for the advice John :) I've attached a picture below of what I think a grub screw bearing is, is that correct? So I'll just place that on the motor shaft near the fan and that would connect the fan blade to the motor shaft? So the clip lock washer (I've attached a photo to show...

Thank you for the suggestion Mike! It's always good to have other peoples suggestion and advice. Yes you're right there are more than one way to achieve things. I like your idea, I never thought of it that way; I might try that method as well to try and have fun experimenting :) The piece of...

Thank you for the helpful advice Mike! I haven't thought of using those appliances you've suggested so that's a really good idea. At the end of the wooden dowel I'm going to be attaching a piece of ceramic or something horizontally using a wire wrapped. And I will build a small wooden...

Thanks guys! Yep they are pretty strong, I couldn't remove it without destruction though. But I guess you can just purchase these lock washers online and use them again. One thing I want to know is, is it possible to use a lock washer (i.e. circlips; eclip) that's snapped onto the slot/groove...

No there was a tiny broken drill tip but it fell on the table, so I know it's not stuck inside the hole. I just bought the Rocol RTD Compound online so just waiting for that to arrive. Yes actually I might just drill another hole right underneath it if i can't seem to drill through the hardened...

Hello Sorry if this question is unrelated for this forum but I have a question regarding fan blades secured onto the motor shaft using lock washer … For a normal 10" air circulator fans the lock washer or any mechanism used to secure fan blade coupling onto the motor shaft are more simple than...

Thank you for the reply :) oops sorry I understand now! I believe the motor shaft is stainless steel but I'm not 100% sure, (the carbon steel is softer than stainless I believe?) The drill bits i have are Tungsten and molybdenum with 5% cobalt added so perhaps i'll continue to use that but I'll...

Thanks John and Frank! actually I'm only going to be drilling either the sizes 1/16 (1.6mm) or 1.8mm so I think it's going to be fairly easier than drilling 6mm. What do you think would be the best type of drill bits for stainless steel? It's a lot harder as it got hardened so I'll probably look...

Thanks for the advice Mike! I might also try carbide die drill bits or straight flute carbide drills.

Thank you for the advice John and Bernard! Yes I will try that! I too believe a better lubricant/paste would be effective. And as for the HSS drilling bit since the end is pointy so i think that'll kind dig out the clogged, hardened bit!

I've drilled a small perpendicular hole through a metal (stainless steel) 6mm motor rod (one from a normal air circulator turbo fan the Honeywell ones) and i've used a centre puncher to mark for drilling and have successfully drilled a small 1/16 hole in the motor shaft. However I decided to...
