Pfaff double needle machine

[DonInReno]

On the top, the tensioners are the same as single needle machines that sew 138 size thread.   On the bottom end it gets a little more complicated.    Some, especially the older models, use the same hooks as are found on walking foot single needle machines and they will sew up to 138 as well.    However, some are set up for lighter weigh fabrics and the hooks may max out at 92 or even 69 size thread.   The walking foot machines are more likely to be set up for thicker thread, while the needle feed may be set up for heavy canvas or very light fabric.

Also watch out for retired factory machines that were used with binders - for instance mine spent its entire life sewing canvas straps of some kind and the binding attachment protected the bed from obvious wear.    These machines can have paint that looks brand new, but the mechanicals may be worn out.     Mine had been rebuilt many times, but all the replacement parts were high quality so I was lucky.

Its always a good idea to sew on a potential machine with the thread and leather you intend to use.  If that’s not possible I force myself to reduce the top dollar by 25% or so.    If the needle set is not the width you want to use, a cheap import set will run $50 to $75, so factor that in.

Ah ha, the plot thickens, and all that glitters is truly not gold. It is so true that the more you know, the more you need to know.

The double needle will obviously hold down the folded edge (I don’t know the technical term) but the top stitches will be more of a decorative pattern, which brings the thread size to the fore. My guess is a 138 thread size would be considered standard, or maybe a minimum in terms of visual appeal.

It seems to me that when pursuing needle feed machines it behooves you to know all of the particular nuances of said machine. That great money saving deal could potentially end up exceeding the cost of the more expensive machine that should have been purchased in the first place.

Therein lies one of the main differences between the various material feeding systems, and as I think about it (which now seems foolishly obvious) the material as well as sewing style will pretty much dictate the appropriate type of machine that is needed to accomplish the particular job. In my case material thickness is negligible, sewing speed is a none event, compound feed isn’t exceedingly necessary, but at the end of the day it seems that a machine capable of handling larger thread sizes of say 138 - 207 will likely rule the day. I can only imagine how much more narrow the field of search has shrunk with this new revelation.

I am not sure I understand the need for a double needle to make French seams as they are only another sewing line on each side of a seam holding down the overlap

What am I missing

As you figured you don´t need a double needle machine but it is faster and more accurate (depending on your skills) as you see in the sneak peek picture of that video the seam stitches are not 100% equal (this may matter or not depends on your or your customers expectations.)

You are 100% correct and aren’t missing anything. The double needle machine is solely sought after to mask my own inexperience. Those parallel stitches are the finishing touches to any upholstery project. The eye is immediately drawn to the visual effect of how well the stitches are laid down. In my mind, if the stitches are well proportioned and evenly spaced then the only thing that I would have to worry about is sewing a straight line once. Of course if I am unable to locate a machine that is able to handle the larger thread sizes at what I may deem a reasonable price, I will obviously be forced to grind out those seams one at a time like you guys are able to.

Accuracy along with my skill level is the whole point of this exercise.

Again, this is the point. In my case (at least for now) I am my own customer. I ultimately decided to take on the challenge of reupholstering my own cars interiors primarily because I couldn’t find anyone that I could trust to provide the results that I wanted. Some years back I was referred to a guy in Southern California that was supposedly an expert in recovering the original Recaro seats (Classic C & Ideal C) from the 1980’s. I live in the Midwest and drove the 2,000 miles and hand delivered the two chairs, all of the panels, and the hand selected matching leather that was obtained from the Hide House up in Napa. It took the better part of a year before I was able to get the parts back, and the labor still set me back a big chunk of change. In all fairness at that time the guy was semi retired, but nonetheless he has since then closed up shop. He did a wonderful job, though. Since then I have searched tirelessly trying to find someone else that is able to reupholster these Recaro chairs. Believe it or not, all that I have approached either said they are unable or I’ll see what I can do. Well, rather than seeing what someone else can do (which I find totally unacceptable) I decided to see what I can do myself. The reason being is my own satisfaction level. If I do it and it doesn’t meet my satisfaction there won’t be anyone to blame and I can live with that, but if someone else doesn’t meet expectations I will still have to pay for it. Also, I’d be crazy to go to all this trouble for one set of chairs as I have several other cars to deal with. I expect that at some point through this process my competence level will become satisfactory. In order to do this, I just like all of you will have to brave the gauntlet, and one of the best way to go into battle is to have the best tools for the job, thus the double needle sewing machine.

Once you have a double needle, there are a number of fun projects that you might never have thought of - I like the look of a 1/4” double seam next to some heavy duty zippers, and it holds heavy material flat if nothing else.   Sometimes a single exposed row of stitching just looks sparse and if the rows are close together a second row has to be exact or it really catches the eye.

Also be on the lookout for zipper feet - essentially just a more compact foot with less side clearance - these are my favorite for general use.   At least I’ve never thought to myself, “It would be nice if this foot was bigger and more clunky.”  Lol

Ive been a fan of Cechaflo on YouTube if you haven’t seen his videos.

Yeah, see, that’s the thing about shopping for the best tools that you can afford as opposed to purchasing something that will barely get you by just because it’s cheap. As you’ve accurately pointed out, there most likely projects ahead that I may never have seen coming that probably have nothing to do with auto upholstery.

See, now those are the words of an experienced voice that will take some time before I am able to express, but in the mean time I can do everything possible to prepare myself with the right type of equipment.

I have not seen all of his videos, but I watched quite a few, though, and I too am a big fan. That guy is extremely talented.

After discovering that there are a few more things to consider when searching for a double needle machine as opposed to the single needles, the availability between the groups are vastly different. There are a lot less double needle machines on the market then there are single needle machines. This disparity presents a huge problem in terms of searching for any particular model of machine. To make matters worst I find it hard to put faith in most of what can be found on Fleebay. This is starting to feel like finding the right machine may take a lot longer than I had imagined.

It’s been a while, so last night I scanned for a double needle to see what pops up.   I found a few that were mislabeled as single needle, and a few more that the owners didn’t know what they were at all.    Some of the best deals that have popped up in the past were long arm machines in the $500 range - at that price they get snatched up very quickly so you have to be quick. Lol

Now that you’re getting farther in the search, keep in mind that most older Singer models have a near duplicate Consew, juki, or other lesser known brand.

One configuration that works well for me is a Singer 212W140 with a Galkin puller. It is a needle or compound feed and the puller provides a positive feed without marking the top of the material. The 212 lubrication system has a  reservoir under the top cover with a weight on a spring that makes waves in the oil that transfer oil to the wicks. The hooks have reservoirs under them that are supposed to supply oil to the hook race but you need to check to see if it works and oil manually. There are several oiling points that the wicks don’t reach that must be oiled manually. There is no oil pan, just a drip pan.
