Singer heavy duty 4423 or 6600c

[Dominique]

Anyone used either of these machines for leather long term? I had a 6600c and ended up selling it to another leather worker and she loves it and I regret selling it but since been looking into the 4423 since I don't need computerized and don't need a lot of stitching options. Just wondering if anyone on here uses as their everyday machine for leather

Those are not industrial leather sewing machines. They are domestic, or household hobbyist sewing machines. They are neither heavy duty, nor meant for leather. This is the wrong forum to get information about domestic sewing machines. I posted a picture below of a real heavy duty leather sewing machine as a reference. It can sew over 3/4 inch of hard leather with needles as large as roofing nails and thread 10 times thicker than anything the domestic machines can handle..

I have a Singer HD 4423 for fabric, but I haven't used it for leather, nor will I ever now that I have a triple transport machine.

That singer only has single transport (barbs at the bottom that pull the fabric forward), so heavier fabrics can slip and shift under the presser foot, giving an uneven or crooked stitch. It also probably can't deal with the thread size you typically use for leather.

Other features that I've come to love about industrial machines is that a household machine (at least this specific Singer) doesn't have electronic needle positioning that makes it easier to sew stitch by stitch.

I am aware of heavy duty machines.. I have a tippman boss but it was used and needs repairs. I used the singer before and it worked fine I just was wanting to make bigger projects at the times. I upgraded to a consew rl206 but then got the boss and wanted that to be my main machine. I do not have a budget for a larger machine I am looking for anyone who has used a singer for leather since I know the one I had worked just trying to see if I have to go get the same one or not

What brand is your machine?

I have a Dürkopp Adler 69-373 that I bought second-hand refurbished.

It might help if we knew what kind of leather you sew, how thick and thread thickness. 

Beyond garment leather, domestics get dicey quick.

Actually, your question was if anyone here used their domestic for leather - not me. Plenty try but it'll be interesting to see if anyone chimes in with a yes.
