Necchi Mira BU sewing machine demonstration

[@bryancathey3242]

First and foremost, thank you for the time and effort you put in for us viewers ! I don't own a Neechi BU just yet but found a really clean looking BU (just a BU, not Nova, Mira, etc) for sale near by for what seems to be a great price ($175). It has new powerful motor and a new electronic foot pedal. Iv'e talked to the gentleman on the phone a couple times setting up a meet time. He is a sew'r himself and has 1/2 doz machines. Here's where I need your help, he said he recently loaned it out to his sister and when he got it back to sell he said he can't get it to sew like it had when he first acquired it. (He said it sew'd amazing) It's bunching up thread on bottom side. He has tried new needle's, bobbin, bobbin tension, top tension, remove and re-install bobbin case etc. Now I don't know his knowledge of repair and diagnostics. Now he really doesn't want to sell cause he can't get it running. I hate to pass a clean BU for a more than fair price. Could it be as simple as the timing got knocked out ? I don't know how hard that is to do. Any thoughts of your would be appreciated. I am still going to go see machine tomorrow but wanted to go into it a little better prepared, ie How far should needle bar come up from bottom when hook is right behind needle? How close should hook point be from needle scarf ? Does a BU have timing marks on needle back like Singer's do ? Thanks again for you video's.

The machine is probably out of time. Most likelly the needle timing. I dont remember if there are marks or not. but when you go look at it, check. IT should be pretty straight forward to time this machine. I might have a service manual, I will have to check

The more I look at these, the more I really really like them, quite impressive. I'm fascinated by the 'wonder wheel'. Many thanks for the video.

These machines are amazing. I would love to have one in my collection. Just happy I get to work on them occassionally

Question about leather: Would it be limited by the motor, or by the machine's ability to handle the stress of sewing leather. I can rig up a pulley reduction system to give more torque and less speed at the needle, so the motor wouldn't be damaged or overheat, but if the machine itself can't withstand the torment of leather stitching, then I'll rethink buying one. Many thanks for a wonderful video.

Thank you for asking your question. This machine is suitable for garment leather. It is a domestic machine. Could it occasionally be able to tackle a heavier project, sure. If you are looking to do heavy work all the time, I would seriously consider getting an industrial machine. I would be worth the investment. Even an old Singer industrial is a great way to get started with heavy projects.

thank you. I'm sure you are 100% correct, and even if I bought one for frequent use with medium leather, I wouldn't do it anyway, It looks so beautiful, and If I ever had one, it would never be abused in such a way. @@tksewingmachineandrepair4243
