Rex RX-607Z Problems(and potentially solutions)

- Hi there, when I received the machine(purchased from Amazon) it was running ok, pretty noisily, but as I started stitching through my sails(through 4-5 layers of Dacron sailcloth) I noticed there was quite a bit of play in the needle shaft(excessive deflection). I proceeded to take the front end apart, and found that there was a poorly machined bore in two parts, which allowed for a slight jiggle. I ordered new versions of these, however now the problems are as follows after assembly.
Binding in the Left Middle Right needle position selector, and sometimes it won't go into Left or Right positions. Related to this, the needle bar appears to not move enough with the needle position selector, and, it is too far to the left.
Walking foot doesn't "walk", instead it goes forward and backwards, I likely need to just raise the foot.
In zigzag mode, machine will bind after one revolution(It doesn't complete one stitch). The machine will run indefinitely although not smoothly in straight stitch.
Sorry about the mess, currently everything that should be on my sailboat is at home so it's a bit of a clutter.
The REX is NOT the same as the Sailrite. I bought one and, after learning everything I could, realized that it wasn't setup correctly. After going through the entire machine, polishing and adjusting, it works fine. At some point I'll probably get a Sailrite Fabricator, or Juki. Until I need a better machine I'll just will stick with the REX.
You should do a video on presser foot timing. They are different than nailright. Also some nailright parts are diff than rex. You will have to modify the rex. Be careful of the metric screws. They will strip out the holes because of less depth.
I wish Sailrite was not so snobish, I guess it is their right, but they are the only company that provides any real service instructions on all these machines that are all the same, but have so many brand names on them. I bought my walking foot machine says it is a Mercury M-530. I bought it at a sewing machine store about fifteen years ago.
There is very little information on adjustment of the actual walking foot mechanism ( the mechanism that causes the feet to move up and down).
Well, Sailrite took the chinese sewing machine castings, and made a company based on providing customer support for the ones that they distributed. They later on found out all the issues with the machines, and gradually improved upon the machine enough to warrant shelling out for new castings. I know what you mean by snobbish, but it's their prerogative to deny people who don't plan on purchasing their products service.
The walking foot mechanism doesn't have much adjustment, I'd make a video on it, but there isn't much incentive for me to do so, and it's a headache of a topic. The general gist of it is that the walking foot movement is based on a delayed cam that registers off the needle bar. If you move the pin that makes it move off the needlebar, you will see the walking foot move less(compared to when it is properly adjusted). Note that if you adjust it completely down, the walking foot will not walk at all, which will make sewing quite challenging.
Your comment was given to me as a notification, but didn't post here for some reason. Here is a link to some adjustments to these machines, that you cannot find on the sailrite channel,: www.sailrite.com/Setting-Foot-Height-Range-of-Motion-Video? th-cam.com/video/6_HsRh2Q7Uw/w-d-xo.html
Their video is good , but your machine will have some things that they dont tell you for proper timing. I watched for hours till I finally figured it out.
The Rex is such a fake. For example, on the deck to the right of the needle plate, there are 2 small holes. On a Sailrite, those holes are threaded for mounting accessories like hemmers, etc.
On the Rex, those holes are not even threaded, and the hole on the left doesn't even go through. They just put holes there so that in pictures, it would look like it would accept accessories, which it DOES NOT..
This is false advertising. Nothing about the Rex reflects quality. It is junk!
This is not the same machine as a Sailrite even though they look alike. They are both based on the same design, but Sailrite has higher quality and tighter tolerances on parts that are critical to precise and reliable and durable operation. You can see how sloppily the Rex is manufactured. How can you expect Sailrite to support a Rex? Great customer support is part of what you pay Sailrite more for, too. In short, you got what you paid for.
I don't expect Sailrite to support a Rex, I'm not sure where this comment is coming from when I laid out my views on Sailrite in a comment below this video, when a person called Sailrite snobbish for not offering support: "Well, Sailrite took the chinese sewing machine castings, and made a company based on providing customer support for the ones that they distributed. They later on found out all the issues with the machines, and gradually improved upon the machine enough to warrant shelling out for new castings. I know what you mean by snobbish, but it's their prerogative to deny people who don't plan on purchasing their products service."
Furthermore, I posted the solution to the problems in the video in a follow-up video so that others can learn how to fix their own machines, as I believe in freedom of information. In addition, poor running quality of these machines is partially due to not having been run-in, as usually, most machines will be run in prior to being sent to a customer, whereas cheaper units will forgo this.
Regarding your first statement: "This is not the same machine as a Sailrite even though they look alike. They are both based on the same design, but Sailrite has higher quality and tighter tolerances on parts that are critical to precise and reliable and durable operation." Coming from a machining background, it is evident that the parts for the Rex are made from the SAME molds as Sailrite. It would be uneconomical for a company to reproduce the molds to make a shitty product. The molds for lower bin items are from previous vendors/casting companies that Sailrite used to manufacture their machines. Molds have a certain lifetime(as in units they can make before they warp or otherwise are out of spec) before they are no longer used. In China, they take spent molds and continue making parts, but those parts are no longer deliverable to the company that made the purchase agreement, and those parts are used to build off-brand items.
