Unidentified sewing machine accessory

[Arron]

Hi. I was recently given a Brother industrial walking foot sewing machine by a departing neighbour. I can identify most of the various accessories which came with it, except these. Any ideas, anyone.

Cheers

Can't help with those. Got no idea.
What model Brother?

They are drop guides:

One uses them as a reference from the previous lines of stitching. Say you are making curtains and fitting the hooks at the top. You need the stitches for each pocket to be the same distance apart. If you were to make a stitch every 5cm, this is how its done.

This attachment fits onto a downward facing post via the circle/hole and the screw is tightened to grip it on (or even the sewing needle post, depending on design). The little lever lets the ugly bar slide left and right. Obviously the overall range is limited.

This is what a modern one looks like....

Thanks Woodpixel. I had noticed the sgq1 stamp on it but couldn't get a hit on google. Mystery solved.

Looks like a nice machine. Should do everything you need.
Clutch motor or servo?

[Arron]

Clutch.
My understanding is the servo motors give better low speed control. Is that right ?

[China]

servo motor will allow you to go from one stitch at a time to full speed, most are fully variable, plus you can set to what ever spm you want
pretty much all leather workers use servo motors these days

[NCArcher]

I have a servo on my walking foot machine. Much easier to control than a clutch motor.
You can buy good aftermarket servo motors fairly cheaply now but some are better than others so do your research if you go that way.
Brother have good manuals for your machine available to download if you don't already have them.

[Arron]

It would be good to have a servo motor but it's not on the list just yet.

In the mean time is there any problem fitting some kind of home-made stop to the foot pedal? I'm thinking something which would limit it to a very low speed, but swing away when not needed ?

I can get the machine to sew very slowly as it is but I can't do it for long, one lapse in concentration and it zooms off.

A clutch motor spins at full speed all the time. Pressing the pedal moves the drive pad into the spinning portion. You can feather it to get lower speed control but it takes a lot of practice.
You can install a speed reducer which is a small and large pulley in between the motor and machine. It just reduces the rpm at the machine and makes it more controllable.
I have heard of people putting high density foam under the pedal to try and restrict the rate of movement. Might be worth a try.
