Turn the knob on the top down for more. Bob

The bobbin goes in so it turns counterclockwise. Oil anything w/hole & open the cover over the needlebar & oil all the pivoting joints in there too. Also oil the outer part of the bobbincase everytime you go to use the machine & or everytime you replace the bobbin. Open the top cover just to the left of the handwheel & you'll be able to see the raise part w/o oil hole in it . On these oiling diagrams,the oil spots are marked with arrows. Bob

Like Greg says it depends on the # there's a 211G157 needle feed w/reverse,but yes,in the walking foot machines I don't know of anything under 166. Bob

Ok,I found out the file is to large to upload here, so if you want to PM me your email address I'll email to you. Thanks,Bob

Do a search for Tippman Boss,you'll find out all about it.

Looping underneath is the top thread it's either to loose or not threaded correctly.

Here's a pic of the tension release bracket & the rod that pushes on the back of the tension unit,you need to see if this rod is moving foward when you lift the foot all the way up if so this bracket isn't broke, the bracket right behind the tension is adjusted by bending it alittle towards the back of the machine. You can shine a light into the side of your machine & look at this part & see if it's broken or not. Bob

Ok,the party that the bobbincase sets in is called the hook basket & it is held in place from spinning by a little tab of metal the top so take the needle plate off & look on the leftside & you'll see to U shpaed part on the basket & then the tab of metal it goes into on the leftside. Clear as mud?? Bob

Yes,you should clean off old locktite before you reuse a screw,acetone or contact cleaner will work on the screw & in the hole. Bob

The correct one for your machine doesn't have flat sides like the 15 class,they are very similar though enough that I guess they're working for you. I will check the difference in the thickness tomorrow & let youy know as we stock both. Bob

The largest thread this can use is #138 & sew to 3/8 more or less depending on the leather. The 206 bobbin goes in underneath & can use to#206 thread but it won't sew any heavier than the 255 Bob

The largest thread a 78 would sew is #138,if you want to PM me your name & address I can send you a short piece so you can compare. It's hard to tell from the pic but I'm almost certain they use alot larger on a mitt. Bob

The Singer 132 will sew alittle heavier & use thicker thread than the Juki but if your sewing chaps, purses,wallets & thin leather the Juki does have reverse

Great buy!! The new clutch pad goes on the motor side.

Use #160 needles with #207 thread È needles with #277 thread Bob

They are ok machines for sewing canvas & etc and I have sold them to inmates in prisons(do to space limitations) but to be honest they do not work that great because you can't use any thread bigger than # 92,some times they have problems with various parts breaking,I don't know if they are pushing them to the limits or what but they tell they just sew wallets & belts. It would be great if they held up better since there portable, but they are really just a modified household type of machine. I feel you would be money ahead to get an Industrial Machine and as long as you got the correct machine you will be able to spend more time sewing & get a better looking job done to. Bob

The RB-1 is alittle newer machine with a different handwheel (stamped steel) the RB should have a cast iron wheel the look similar to the old Singer 111w machines. Bob

That's not a bad price f/$500.00,you gotta remember,the machine will make or break you so you want to get the best!!I would get the 226. Bob

Well the 226 has reverse & can sew as much as the 78.

The Singer 78 will make you a much better machine than this one.Oh the 78 will usea max of #138 thread were this machine will max out @ 69 thread.This Union Special is more for sewing thin clothing type of material than leather. Bob

We use the blue locktite on every machine we sell & wash out the hole & screw both with some alcohol to remove the oil. Bob

Like Art is a saying if the machine was already sewing then all you need to do is lower the needlebar down enough so when you turn the machine around & the point of the comes to the needle it has to be below the eye so it can catch the thread. Bob

Yes,it can be done real easy by lowering the needlebar,but you won't be able sew over 1/2" thick or your needlebar will hit the foot. Bob

Yes,we have alot of parts for the 31-15 like roller feet,feed dogs,teflon flat feet that would work great on leather & anything else you might need. Bob

The 16-188 has a top feed with teeth on the bottom of the feet this along with the teeth that the feed dogs have make it a poor choice for a leather machine,the 111w style of machine will work much better since it has a needle feed,the feed dogs can be smoothed down if needed & it'll still make even stitches.
