HELP! I was sold the wrong machine and I'm stuck!

Thanks @Matt S 

Would you recommend the Juki 1541 over the Juki LU563?

No problem.

Honestly, I've used neither. They will be fairly similar machines but the 1541 is a newer model, and is available in slightly heavier duty versions.

I used to own an LU-563 and sewed on a boss's 563 for two years. All I have to say about them is that I couldn't get the forward and reverse stitches to match. I was sewing vinyl, so mismatched reverse stitches wasn't a big deal. If you are contemplating buying a 563 I advise you to test it first. Misaligned reverse stitches can totally filigree leather.

Personally, unless the 563 was in perfect condition and adjusted so the reverse stitches match the forward stitches, I would go for the newer DNU-1541. But, I strongly advise you to test it first with your own leather (use a leather point needle!). Make sure the reverse lines up with forward stitches and that the appearance on top and bottom is acceptable. Bear in mind that the pressure on the inside foot can increase or decrease the puckering on the bottom layer.

Thank you so much!

Welcome, @JHBH2!

I'd suggest you try the steps mentioned above (leather-specific needles, smooth feet, hammering stitches etc.) but that your best bet is probably to look for a new machine.

If you're looking for a reputable sewing machine dealer who understands what you'd need for sewing leather I can personally recommend you Hartley Sewing Machines in Walsall, Castle Sewing near Leeds, and College Sewing in Bury. College certainly sells Juki 1541s but bear in mind that £950 for a used one is roughly half what they cost new. You've got a company called Rowlson in Nottingham who do industrial machines, but I've not heard of them before and it looks like they mostly do machinery for sewing curtains, carpets, mattresses etc. and may not have the experience to advise you reliably on machines for leather. It's possible that they may even offer you a trade-in on your Juki.

Ideally you'd visit a machine dealer and test drive any machines they propose using samples of your leather, but that's not possible right now. This would give you a feel for each one and you'd get the opportunity to learn how to make any common adjustments. Is getting a functioning machine very urgent or could you wait a while?

Since you make mostly smaller goods you might want to look at getting a cylinder-arm machine on a smaller table, which would take up less space in your living room and give you more options for sewing trickier items. The main disadvantage is that there is less area to rest your work on as you sew it but there are add-on tables available for some models, if you feel that you might want more support.
 

A "jump-foot" is a passive, rather than active, walking foot. The foot is mounted so it can be dragged backwards by the work, then jump forwards again under spring pressure when the pressure on the foot reduces near the top of the stitch cycle. It's less likely to grab or drag than a fixed foot but not nearly so effective as a true walking foot. You used to get them on certain models of Singer 45K, but they pretty much went out with winklepicker shoes and 45RPM records.

Thank you.

JHBH2, hello mate, ive got a Singer 211g166 and one of those Chinese hand-crank machines,  i live near the M1 motorway services, i see your only in Nottingham "i say only but it depends what side"  but if its any help your welcome to come and have a go with them and see if they are (the singer) what you need?

[ASAuLTCases]

i didn't say but on the singer that's compound feed,i can adjust the feed dogs so they don't come up high enough to damage the leather ( come to think about it take them off altogether),

looking at the exit ring it is leaving makes me wonder how big the needle hole is in the footplate? it looks massive or you use very small needles? that looks suspect to me as an engineer, I don't have the experience as a machinist, but it would have to be a blunt needle pushing into a large hole and forcing through the leather?  what needles are you using?

another sewing machine dealer is AE sewing machines UK, ihave only brought one order from them of needles, small pulley, bobbins, seam cutters, needle threader, thread  etc but they where great, big selection of needles, you can download your machine parts diagrams/list, they seem to have a huge spare parts department, you should be able to check if your needle hole in the footplate has been drilled out to hide damage from a stray needle,

but a smaller hole and a sharp leather needle would help you a lot, a schmetz RTW leather needle give a lovely diamond shape hole and a lovely looking saddle stitch "Z" on my machine they do,

the offers there if you want to try it,

That's really kind thank you! I'll PM you to take you up on that!

I'm looking into the needle things

You can reduce them somewhat by using leather needles that have sort of a chisel shape rather than a conical shape point if you aren't already using them.
Can also lightly hammer the bottom stitch line to hide it somewhat.

They sold you a top/bottom dual feed machine when you needed a compound feed walking foot machine, with totally smooth feet.

You can try to minimize the tooth marks and puckering by reducing the spring pressure screw or screws on top of the head. There will at least be one large screw over the outer foot that pushes against a heavy coil spring inside the head. There may also be an adjustable spring over the inside foot. That one should be backed off as much as possible to minimize the puckering.

Pucker marks are a fact of life with walking foot machines. That is because the inside foot presses directly around the edge of the needle. The only way around this is either a bottom feed only or a jump foot machine (rare).

I'm trying to figure out the needle issue. There's a deluge of info online and its hurting my brain. 

The machine uses 135x17 (and I THINK this translates to 135x16 for leather needles?)

I had a Organ DPx17 (125/20) in the machine. 

I've swapped it out with a Groz-Beckert D/TRI point, size 110/18 - but I'm getting the same "bursting problem" with them, if not worse!

I could weep, I'm trashing so much leather and I feel like I'm going around in circles - it's obvious that I need to change the machine but to throw in an extra problem - we're meant to be moving to Dubai in a couple of months so I'm reluctant to fork out on a machine that'll then need to be shipped over... but industrial machines look like they have to be imported over there anyway...

As Wiz alluded to earlier, the "bursting" problem is pretty much unavoidable when sewing leather on a machine (it's the nature of the beast). You can reduce it somewhat by playing with needle size but you won't eliminate it. The only way to get a nice hole appearance on both sides is to hand stitch! Theoretically using a pointed needle should provide the best result visually because it's not cutting the leather, and on thin leather this should work, but on thicker leather it may create problems with trying to pull the thread back up through the leather.

Sewing leather on a machine is always about compromise. If you're a perfectionist then hand stitching is the only way to go.
