MtlBiker Report post Posted November 19, 2020 Well, I did it! I pulled the plug and ordered a new Techsew 2750 PRO with speed reducer. Now I just have to wait until one can be prepared for me (they're back-logged). Luckily I'll be able to pick it up in my SUV and won't have to wait any extra time for a shipping company. Thank you all for the helpful comments and advice. Think I'll order some v138 poly thread to try on that machine. My RB206-5 is supposedly at the limit with v92 and I'm looking forward to seeing how nice the stitches will look with v138. Quote Share this post Link to post Share on other sites

Just so I'm clear, you are talking about the 2750 right (and not the RB206-5)? I've been told that the practical upper limit for the RB206-5 is v92 so I haven't tried anything thicker. And I hadn't heard about using a different bobbin thread weight than the top thread (remember, I'm a beginner). What would be the reason to do that? Just the looks of the top thread stitches? Not that I'm going to buy any, but do you think 207 could be used on the top and the bobbin on the Techsew 2750? I'm going to order v138 to try on the new machine. I'm sure it'll be more than adequate for where I am in my sewing career. Heck, even the v92 is probably more than I really need for what I'm doing.

DonInReno Report post Posted November 20, 2020 Your 206 should easily sew with 138 thread. Whom even said 92 is the upper limit either had an improperly adjusted machine or didn’t know what they are talking about. Quote Share this post Link to post Share on other sites

Using 207 on the top is for appearance only. For stitch strength, it's no stronger then the weakest thread. Quote Share this post Link to post Share on other sites
