Monster Flange For Speed Reducer :-D

[Constabulary]

I recently "liberated" some parts of an old ADLER work stand. I looked through my records and figured it is from the 1940´s (manual printed in 1947)

One of the legs had a HUGE cast iron flange bolted on.The stand was meant for a treadle driven Adler 4 or 5.

The flange weights about 8 pounds and has a 3/4" shaft. This thing is really MASSIVE!

I have the same stand (but restored) on my current machine table so the flange will serve me as amount for a speed reducer sooner or later.

I just wanted to share this

Scheming to make a speed reducer too. Please keep us posted on your progress

What do you plan to use to shim it out "into the field of play", so to speak? Won't it have to come out a long way?

Let me try to explain...

Since I have limited space for "lots of" different sewing machines my idea is to make my current table a "universal table". I´m already using it with 2 flat bed machines (Singer 111G156 + 306 G2) both machines fit in the same cutout and have same hand wheel position for the V-Belt so they can use the same bobbin winder as well.

Since it is a quite long table (about 60" x 24") I´m planing to put 2 different cylinder machines (Pfaff 335 + Adler 105 or Singer 153 + Singer 45K or something similar) to the left edge of the table. Each machines will be bolted on a about 12" x12" wooden plate and these plates will be bolted to the table the way they can use the same motor with just different V-belts.

With other words, I will have 2 motors and use 4 machines on just one table - Thats the idea

I have collected a nice lot of parts from vintage Adler work stands (or tables) so I will put an additional leg to the left side of my current table and on this leg I will bolt the "monster flange" for the speed reducer with 3 or 4 pulleys (step pulley - or how do you call it) and this step pulley can be set on different positions on the shaft. The step pulley will have ball bearings and will have adjustment rings on the right and left side so I can move it on the shaft. The flange fits exactly to the 4 square holes in the middle of the legs.

I hope I explained it well - D' ya understand what I mean?

At the moment it is just and Idea...

So here is the current situation:

Might aid in the speed of the cylinder arm machine swap?

These take to much space on the table. I will use wing bolts or so. Speed is not important. I´m doing this as a hobby so I have all the time

Today I received the two step pulley made after my specs.

A sealed ball bearing on both sides for 15mm shaft, pulleys are 2", 4" and 6", milled out of aluminum. Each pulley cost me 40€ (about $55) incl. shipping. I´m quite impressed of the quality.

I´m getting closer to my idea...

I like the pully. I made one very similar a few weeks ago for my Pfaff. I did not have the 3 groves, just two. I was going for as much reduction as possible.

Just finished the 1st speed reducer. I wanted it the way that I can move the step pulley on the shaft. Thats not necessary but just for the case... You never know. The one with the monster flange will follow later.
