Sorry,it left around noon.

Jacob,One of the shoe shops had me order the color on the left for them for the LV purses it's in size#69.

The shaft has 2-grooves on it approx. 45degrees apart that the head of the screw seats into,there is no keyway on these machines.

No,I priced one from Pfaff once & it was $150.00 (still cheaper than a reducer & servo) BUT you need a servo anyways.

It's a step in the right direction BUT the pulley only has on set screw & if you start sewing anything very thick in time it won't hold,that's why they put 2-screws in the original pulley that line up with the grooves in the shaft. Sailrite is high priced on everything they sell,we sell the for $4.00 a pk.

Those 135x17 are for cloth...order what I wrote 135x16D like I said is for leather.If you can't find them we have them in stock in all sizes.

If your sewing leather you want a leather point 135x16D size#23 for 207 thread. Here's a chart for different sizes of thread; https://www.tolindsewmach.com/thread-chart.html

When you use #207 in the needle be sure to put #138 in the bobbin.Or you'll never get the bobbin thread to pull up.

The Rex is a good motor to bad they don't put a 2" pulley on it.

Good job! Nice looking machine too!

Like Wiz said it's a 29 something,there's a model# on the brass tag behind the wheel ask them what it is & let us know.

Parts are pretty expensive & changing it requires a good mechanic.The price varies on the width you need.

Yes,how far apart are the needles?

The 111w would be a better machine for upholstery,feet selection is much better,the 111w cording feet will fit the 144 but they won't work properly because of the wider gap between the feet.If your not doing cording then the 144w would work if want to use it.The 111w will run smaller thread like size #69 & #92 that the 144 will have tension problems with since it was designed to use #138 & larger.

The 331K4 is the same machine w/a smaller handwheel & different casting BUT it does have reverse,but still won't sew any thicker than your 31-15.

One more fly in the ointment,starting 9/24/18 there's a 10% tariff on many goods from China & sewing machines & thread are on the list & it will be going up to 25% after 1/1/19.

This should help you.

I'll never forget the day I went to a service call in town here & walked in a room with 2 of these clunking away side by side.What a sound!

Yes,they will interchange,the knee lifts are different & you'll probably have to adjust the belt because the pulleys are a different diameter.

Yes,I just got the news a couple days ago & it starts on 9-24 any imported machines will have 10% on them & after 1-1-19 it's going up to 25% so if you've been setting on the fence about a machine you better make your mind up soon.Or it will cost you more $$.

138 thread normally will require more tension,you'll get a better looking stitch by going one size smaller thread #92 on the bobbin.These feet are being discontinued by my suppliers do to lack of demand.Like Const said you can grind off the teeth & then also grind or cut the front off to the front of the hole to create an open toe with a Dremel.

That could be hand lift versus foot lift.

Search Consew 206RB-1 here on Leatherworker & you'll find answers to all your questions.

Top of the handwheel 23",top of casting 20",you should take the wheel off to prevent the top shaft from getting bent in case it moves around during the trip, I'll agree w/ Uwe you need a sturdy wooden box to protect it.

Thanks for posting this BUT it's a shame it's so far away.If I were to bid on anything I'd have to leave before I knew if I got the bid since it would take me 3-days to get there! In my big truck I can only drive 11 hrs a day & it's a 3-day trip 1,900 mi one way @ 10mpg x$3.00 a gallon =$1,200 in fuel alone!then motels & eats another $700.00.I'm sure someone closer will get some good deals.
