I recently just bought a UDM for doing some light polishing and for using AIO's with. I have only used a makita rotary. I found that while polsihing with the UDM the vibration is just horrible. Is this normal. Also it is bearable below speed 4 but anything after that my whole arms just vibrate and at speed 6 it feels like after a day of polishing I would have none some seriouse harm to mhyself. Will E-Shine refund me my purchus?
Yes, that is typical of the UDM. Before getting the Flex I would only polish with the UDM and after 6-8 hours of polishing at speed 5 or 6, my hand would end up numb, weak and feeling as if I had a really bad case of arthritis (for up to 3 days). Now that I have a Flex, I only use my UDM to apply an LSP or polish tight spots with a 4'' pad. Oh, I also use it with brush attachments, but never for full polishing jobs anymore.
I've never used the UDM but if it vibrates as bad as the PC there is no way I'd use it. If you are used to using a Makita why go with the UDM? Seems like taking a step back to me...well just wondering that's all. DA's have a purpose but I rather use a rotary. As far as eShine refunding you...not sure how that's going to go but worth asking, you never know :shrug:
The UDM has much tighter and harsher vibrations than a PC, especially on speed 6. The PC vibrates a lot but not as harsh / intense.
Nica, In the past I used a rotary because I worked for a detailing company while in high school. Now that i'm just getting into having my own clients, I was a little weary about the "what if" I burn a customers paint. But after this experience with a DA polisher, I am defently going back to the roatary. MMmmm defently interesting to hear. That would make sence because it looks like the orbit housing on the UDM is a larger diameter I have in the past. It just seems like you go though sooo much more product than with a D/A polisher
That's the downfall with DA... I'm used to it though, well since I've started with the UDM . One time during use, my arms felt like "vomiting". Lol I don't know how else to explain it.
If you are concerned about using a rotary on a client's vehicle, but you don't like the UDM, I recommend the Flex.
Best thing to do is contact the manufacturer, their info is on and in the box. They are very good and if they agree to replace/refund the machine, they will simply credit us for a unit then I can refund it. If I simply refund the purchase without you contacting them,I can not resell the unit and will be out on the cost.
