Does you feed dog still have the points on it & is the stitch length set to the same length as the points?

grind them off

I have seen many casting flaws over the years. I think this one slipped by the factory. They may have filled it but the patch fell out later. Repairing defects in casting is common in foundries. Really will not hurt the operation of the machine. I have Consew 28 It does not have a feed dog just a slot for the needle and inside foot to feed works well and does not leave marks on the bottom. Eric why does this have a feed dog with no presser foot over it?

Cowboy 3200 & consew 1206rb

I have seen some with the needle set a little too far down and the hook protector deflects the loop causing the hook to miss it.

put your thread thru a soda straw between the spool and the eye above it. It will cause the thread to unwind rather than pull off the end. I have the un roller types on my Randle and my Landis one they work great. They need a spring in them so the thread don't freewheel when you stop sewing suddenly.

I really like my Consew 1206

you need a lighter duty machine. You can do it with yours but it will need a lot of adjustments and a flat table adapter.

I put petroleum jelly on the cork in the clutch to give it a little more slip. singer used to make a product for this. Seen it used first in the shoe factory I worked in 50 years ago.

16-88

Those are the wrong bobbins. correct ones are flat on the sides

I have a bobbin winder but you can chuck on end in a drill and support the other end in a small hole in the end of a table. run the thread thru a screw eye at least 3 feet away and turn on the drill. You are a blacksmith you will figure it out

I have a consew 28 that all most never leaves a mark but, it is not a cyl. arm and it is not a walking foot like most think of it has NO feed dog on the bottom, needle and inside foot only it feeds well and is as close to no marks as I can get with a machine. You are asking a lot from one machine.

I have sewn with 69 thread on that class machine. I use 7x3 # 18 needles but I had to change lots of adjustments . Needed lighter tension springs and change bobbin tension. Those long skinny needles flex a lot as you go over seams etc so you are going to break some needles. I didn't think it was worth the trouble. As said above maybe time for another machine.

tip the machine back on the peg and it's right in front of you on the bottom of the pump. no tools needed just swing it open or closed with your finger. the hook lube adjuster is also on the bottom to the right of the hook shaft bearing. It is marked small or big, both adjustments are clearly covered in the manual (pg. 12 and 13).

Wiz, yes, the oil has the wicks wet in the head and I can see oil in the clear tube that oils the bottom part of the head. I sew as slow as 2 stitches a second. but very seldom faster than the lowest setting on the servo. There is a simple little by pass valve on the pump and it is completely closed for slow speed sewing. This needs to be opened up to about 1/2 if you sew faster as it will over oil everything. the hook lube is adjustable. The external walking foot cranks still need to be oiled by hand. I have 2 other pumpers that do not oil well at slower speeds but the 1206 oils well at very low speed. Most of the main shafts are hollow and have felt plugs in the ends. if you touch them you get oil on your finger. I know this is not in line with your experience of pumpers but this one seems to work at slow speed.

my 1206 oils fine at slow speed.

I may have a 16-88 needle bar extra.

My Landis 1 has sewn 8 0z. leather to 1/2 inch plywood several times. I use 415 thread 27 needle. the Landis does it easier than my Randal. I have also sewn 1/4 inch plywood with my 3200 Cowboy.

mine takes a 40 inch belt, but a 39 will also work.

not enough info. how thick, what are you making, what do you consider affordable etc

I have 5 of those on machines here and must have installed 20 or more in the past 3 years. I did get one that never ran at all right out of the box. Bob replaced it no questions asked.

I have one and I like it. got mine from Toledo Ind. sewing machine. I have used it with 207 thread clear down to domestic sewing thread. Mine will sew a good full 3/8 inch of firm leather. Bobbin winder works great. reverse into the same holes. I did have to deburr the outer foot and hole in the needle plate but I do that to every machine I get. I have a bad habit of not taking the work out the back so it frays the thread when I pull it to the side.

a ramp to slide it down would be very simple. maybe only 20 inches difference from truck to pickup. tie the ramps so they don't slip of the truck. put the table together then slide the machine head off the pickup onto the table. Go slow be careful.

On some machines you can loosen a set screw and push the tension assembly deeper into the machine.
