About the only thing I can say is do not get a simmons. Their quality control has gone waaaaaay down hill and warrantee support stinks. My first two were great but the one i bought in 2013 is horrible.

No idea why your lamps are blowing, have you thought about an led replacement? They run on dc so no need to remove the rectifier.

By coincidence, I'm getting ready to freshen up my Cessna's interior while its down for annual next week. I'll give the Ceconite a try in place the no sag spings. Do you use the regular Randolph super seam cement?

Wow! Those seats look great! I love the color change on the welt, so well done I wouldn't have noticed if you hadn't mentioned it. Really well done.

On a side note, how do you deal with the seat frame webbing? Most of the old Piper seats I've come across have rotten jute webbing. I'd prefer to replace it with nylon or poly webbing, but cant get the frames through the throat of my Juki to sew it. I see a lot of Ceconite used in place of webbing, but am weary of only having a glued bond holding the pilot up.

Thanks,

Jim

Do you have an extension cord on your sewing machine or ac unit?

Mike, are you saying that your tripping the main breaker in your shop if you turn on your clutch motor while the ac is running?

DC servo motors don't load up and draw more current at start up like ac clutch motors do, so you shouldn't have the breaker popping issue. I'm on the road for the next week otherwise I'd throw an amp clamp on my servo and my clutch motors and give you real current draw numbers at startup and wide open.

Low voltage raises current (amps), which makes heat that trips your breakers. If you have any electrician friends you could have them wire in a buck boost transformer in front of your power panel to give you more voltage and more headroom on your breaker.

While my skill set isn't 1/100th what yours is I'll offer what I can. I put a sew green servo motor with a 50mm pulley(from Gregg at keystone) on my Juki 1541 (upgraded from the stock Juki clutch). It freaked me out a bit ay first as its so quiet I heard my machine make sounds I'd never heard over the buzz of the clutch motor... With the speed set as fast as it will go I still have enough control to make one stitch at a time and 99% of the time can stop the needle where I want it with little to no effort. I never had a problem with the clutch motor, but the sew green is so quiet, powerful, and easy to control, I'll never buy another machine without it.

Hi Bobbin, sorry its taken a bit of time to get back to you. A sinus infection and root canal took me out for the better part of a week.

Adjusting the offset helped a lot. My stitches are now within 10% of eachother regardles of what I feed through the machine. The only downside I've found is with the feet raising up  so high its a little tough to use the feet as a refrance for spacing french seams, so I picked up one of those fancey spring guide feet sets.

Mine doesn't have the dial, I think thats only available on the super luxurius -7. I have to open the side cover and adjust a cam/slider on the shaft that the flywheel/handwheel drives. After reading the manual again i'll give it a shot tonight when I get home from work.  

So I'm guessing the Outside foot is dragging on the material when the inside foot is trying to feed it through, thus shortening the stitch length. Changing the lift hieght sounds easy enough, do you know if there are any adverse effects by over doing it?

Thanks for the reply bobbin. I do use the stitch length dial, but at 9 (wide open) I still only get a 5mm stitch with backing, vs 9mm without. This being my first needle feed machine I don't know if this is normal, or not. I do have the owners and service manual, and don't mind trying the inner foot height, I just thought I'd look for an opinion or two from someone with a bit more experiance than I before doing it. Baby steps... One of these days I should probably see if I can find a tech to go through timing, feed dog height, presser foot height ect with me.

Hi all, I recentl picked up a juki 1541 (and love it!) and have a few questions regarding set up of the presser feet. When I sew vinyl backed with 1/2" sew foam my stitch length shortens dramaticaly (30% or so) compared to sewing unbacked vinly. Adjusting the pressure of the feet does not seem to change anything. The machine has an adjustment for the relative height of the inside and outside feet, but I don't yet want to go down that route as I hardy understand that effects the material feed.  Any thoughts?

Regards,

Jim
