Singer 29K-71 all cleaned up

Stitches become shorter the thicker the material thats because of the pendulum effect.

Maybe this thread is interesting fro you:

Yes very interesting. It made me go back and do a second test with the same thread for the top thread and in the bobbin using a piece of  7/128" (1.38mm) veg tan. I got 6 1/2 stitches to the inch.

Photo 3: Side by side of veg tan from first test with 11/ 32" (8.73mm) and the second test with 7/128" (1.38mm) side by side

I am looking at figuring out a method of installing a simple domestic sewing motor to the rear base of the machine. Something along the lines of what some have done with the 29k-4's but the 29k-71 does not have a mounting hole and I don't want to drill one in the machine or the base. If anyone has a suggestion or knows of an adapter plate of some sort I would appreciate the info.

There’s no way a domestic sewing motor would give you any control over a patcher. That and clutch motors…. Servo will change your life on a patcher.

I agree, a servo is the way to go for motorizing the machine for control but I was hoping there was an original motor and mounting plate to electrify the machine available not so much for operation but more for looks. I do have have a spare servo motor but I really would like to keep it as original as possible.

I just this last week acquired another much newer (1998) Singer 29-71 without a table that I am overhauling. Basically it is just about completed, just drip drying from it's redneck oil bath and waiting to be placed on a table. This machine originally came from Landis and has an additional manufacturing plate riveted to the front of the base for Landis's serial number and date of manufacture. This machine had a domestic type 1 / 15 hp, 120 v 50 rpm motor combined with a small gear box controlled by a domestic type foot pedal. The rear of the machine base has five holes drilled and tapped for mounting the motor unit to the machine, probably done by Landis. I guess this was their version of being portable. The motor works, it was supposedly burnt out but I narrowed the problem down to the foot pedal. Someone at some point tried to "fix" the foot pedal and left a part off as well as shorted it to the metal foot pedal housing (burn marks).

Comparing both machines I think the fit / finish as well as the internal gears on the older 1949 Singer are much better casing quality then the 1998 model. I think there was a decline in quality as Singer started to decline when comparing these two machines.
