hey folks,

I have had a couple people approach me regarding this age old issue.

I am SO new to this whole world that sometimes I think things are possible when folks who know WAY more say "been there, tried that".

With that admission up front I would like to enlist the aid of anyone who feels like helping.

The goal is to produce one of the following:
1. A complete handcrank mechanism with 3:1 gears that can be mounted on "non-bossed" machines WITHOUT drilling new holes in the head.
2. An attachment that will allow non-bossed machines to use existing Singer or PRC handcranks.

Makitmama sent me this photo of a rare 127 conversion handcrank

What I am looking for right now is a photo of both types (this and the PRC version) from the angle of the red arrow looking at this area.

Also a photo of diagram of how the area indicated by blue arrow looks on a "normal" treadle machine.

I like the idea of a clamped on mount at the shaft that then arc's under the handwheel to the handcrank.

If there is a point at the red arrow area that will allow mounting (bolting, etc) then we could be good to go.

Ok, I forgot that "I" had one of the original Singer version.. duhhhh

The hand crank I ordered fits my 15-91 clone perfect. screws went right in.

SteveH

cool! I am assuming that your "15-91 clone" does have a motor mount "boss" or lump?

if your hand crank is a Chinese (PRC) version could you take a photo that is similar to the original singer photo above?

That would be awesome!! I have a beautiful Singer from the late 1800's that has no motor boss. I would love to be able to put a hand crank on it.

On the new hand cranks I've gotten, the body is cast in one piece. I've had the same thought about mounting a crank on an old head without the boss. Simplest thing I could think of was casting or machining a boss, attaching it to the head and then attaching crank to the boss. Project wasn't feasible for me because I have a bunch of Singers waiting for a hand crank with bosses factory applied but the idea I find very interesting.

Steve, I have a 66 out of a treadle in repaint right now. So if you want a pic of the wheel end, with a ruler overlaid, I can do that pretty easily. I still the the problem with this kind of mount is that the 27 had a low bobbin winder, and most others have one that also attaches to the wheel shaft. Your metal piece for there is going to have to be really thin.

Sokey.... I am not at the "here is how we will do this" stage. really. I am just trying to gather the pertinent information to be ABLE to come up with that plan.

Still waiting for pictures of the new style of handcranks.

Yes, I would love pictures of your 66 wheel area. I have a red eye "lump" that I could take apart as well but with the Howe and all....

It sounds like I need to get some mechanical info for the 27 as well. I will look at my 28 and my 128 hand cranks as well.

Steve,

At some point in my internet surfing I saw a handcrank mount on a non-boss head where the crank mounted to the wooden base NOT to the head.

Don't know if this info helps any - and of course I don't recall where I saw this.

I also saw this, it was in the Treade On site and applied to a Willcox and Gibbs Chainstitcher. The W&G was attached to a nicely made "box" case and the crank fastened to the side of the case at the correct height.
