With the 20U & the way the bobbin goes in it's hard to make the stitch look right,the other 2 would be better UNLESS you NEED the zig-zag.

Yes,we had problem with the digital readout ones blowing a chip in them.We don't sell them unless someone wants one.We sell a more simple one that has a knob on the front to set the top speed.They run as slow as 300rpm & since they have brushes in them retain a lot of torque @ low speed. http://www.tolindsewmach.com/motors.html

It's perfect for thinner leathers because the top-feed helps to pull it through ,unlike the bottom-feed that will ruin thin leather.

I hate to tell you this but you need a larger machine to sew with thicker thread.

Unless you glue everything you want to sew you'll have a lot of problems with slippage trying to sew real thin #1 since it's only a needlefeed you 'll need to loosen the foot pressure up & also work (loosen) both the top & bobbin tension to be able to use the thin thread & then you'll have to re-adjust everything when you go to thick thread.I always tell people there's no machine that does it all & if you want or need to sew such a wide range of thickness you should get 2 machines.The 4oz would be better suited for a good old Singer home machine than a 105.I would also say that 138 is too thick for 2oz of leather,you need #69 or 46.

I'm with Eric & have welded probably well over 100 machines over the years & don't know of any failures yet,with proper gringing & pre-heating a weld will hold.I've only brazed small parts & use nickle rod on cast.When using nickle rod it's best to peen it as it cools & try to let it cool slowly or it will break the bond of the weld & cast.

Yes,it sure is nice looking! I wonder if he has the lid?

The standard head like that w/reverse is model# 31-32,so I might guess that when they put the clutch unit on it they made it a SV model because maybe they didn't make very many that way??

#92 is no problem & 138 might work by tightening the tension more.The machine looks like it just came right out of the factory,still original needle plate & feet.

You can run it the way it is,if it broke off any higher than that it would be bad.You can braze it with a torch,I would leave the bolt in there & just braze the bottom piece back on it,if you wanted to weld it with electric ,you need a nickle rod & v-grind all along the area to be welded & then pre-heat both sides or else you risk having it crack when it cools.Also clamp it while welding or brazing so it doesn't move.

Corey, Many years ago we used to rebuild these & sell them for car upholstery.The biggest problem is getting feet to fit.Does it have a cording foot?If he needs one get a pic of how the feet mount. This machine is very power top feed like a 16-188 type of upper feed,the bar that holds the outside foot on has been out of production for over 30 yrs.But most other parts will interchange w/a 31-15.You can put a spacer on the foot lift for more lift(if it hasn't already been done)

You have to measure the bottom of the groove on the pulleys,then the top of the pulleys & go in between both measurements.

If you can find an old 3-phase motor (slightly larger HP rating than your motor)that is delta wound all you need to do is wire it to 220 single phase & also wire it to your 3-phase,get a 110 volt motor & hook up a belt to this 3-phase motor get the 1 running to spin the 3-phase(convertor motor) & then turn the 220v single on & shut the 110v starter motor off & as long as the 3-phase Is spinning it'll put out 3-phase.Usually you can find old 3-phase motors pretty cheap.I just happened to buy a trailer that had a new one in it(3HP) & used it. It's run our Bridgeport mill for years on this 3 phase convertor I made.There is some directions on the web.It is very simple though.

Rea Bogle's Grandson was going to take over.But changed his mind & I got a letter from his wife a few months ago asking if I was interested in buying the business.

Looks like a direct drive servo to me.With the panel you can program how many backtack stitches you want @ the beginning & end of the stitch.This is more of a higher speed factory machine set-up.

It takes some careful work but we have welded a couple machines back together in the past,you need to remove all the lower shafts if you can separate the top from the base, v-grind the crack, get the base straight w/some heavy angle & clamps,heat it with a torch & use nickle welding rod to weld it with.Then we grind down the weld & repaint.It takes a while to get it done right but it can be saved. Here's a before & after pic of an Adler we welded. HTH

On heavier items like this UPS only pays when they are "packed" to their standards which means they want it double-boxed with at least 1" styrofoam between the boxes.And as Const said the handwheel & any other parts sticking out need to be removed.It's a shame they can't handle items better than this but we've learn that they don't so I try not to use them either!

They look similiar to the 151 hook but it doesn't have that finger sticking out.http://www.supsew.com/wp-content/uploads/Superior/99MasterCatalog/#/382/

It's a 332,333 Consew double needle that will not work for leather.

Yes,Madmax is correct the 794S smallest we can get is #160(#23).

Once in a while certain threads will slide out of first tension while sewing so we always recommend running the thread through 2-holes & this applies to all machines w/a spool that has 2-holes,Singer 111w,Juki 562,563,Consew 206,226,277 & etc.

Yes,you find out as we all have iy pays to spend alittle extra for certain things esp tools.Give Barry King or Bob Beard a call if you want some good stuff to work with that will last a long time.

If you look underneath,just to the right of the race(what the shuttle rides in) you'll see a large slotted screw,towards the bottom,you can loosen this & move the race left to right.

The plate on a Pfaff has a hole in it to put the oil into this wick area.

Yes,they are there to hold oil & release as needed,this area of the hook spins around & the other part is stationary so it needs a drop of oil everytime you change the bobbin but in factories @ higher speeds it's good to have oil there all the time.All these Pfaff hooks are very expensive so they don't want them to wear out.
