Well same problem that always happens sewing foam in a backstitch and the needle jams. A rat nest ensues and I have to reset the safety clutch.

This time my hook timing is off? and my thread is fraying trying to hook. The needle thread is just jamming under there and not looping. Any ideas?

I’d blow the bottom end with compressed air, take the bobbin case out and oil the bottom end.... then time it. Mine was just snarling and I had to retard the timing oh so slightly.

I have blown it all out taken it apart and now looks like I have to re-time! Thanks Rev Upp

@Revv Up ,

It looks like you have customized your foot. Pretty cool!

Good eye @BigRig it does help with the fine stuff but I think I’m going to try it with a regular foot and cut it down too like John suggested.

@Revv Up

Watching You Tube for Hook timing of a machine comparable to mine. 225 R Consew. They say 3/32 from the bottom and hook 1.5 mm above needle eye. That's just impossible to measure.

Here’s how I would do it, find a piece of 3/32 flatstock .... rotate crank to bottom dead center, hold your 3/32 jig against the top of the needle bar and use a jiffy marker to mark down the needle bar 3/32. Now rotate crank till your new mark lines up with where you held the jig. Viola

The distance off the needed I just do by eye but feeler gauges would probably work.

Let me know if a pic would help

@Revv Up ,
A picture would help. I decided to give this a shot since my closest mechanic is a in another city.

Exactly why I had to learn to do it myself, after you have done it a couple times it only takes a couple minutes.

The jig, as you can see my spec is 2.5mm from BDC


Ignore the blue, it’s from the last time and the oil on the machine smudges it after a while, new mark is orange, make the mark tight to the jig

Now rotate your mark until the top of the line is flush with where the top of your jig was held (I haven’t rotated crank yet in this pic.


Clear enough?

Awesome trick @Revv Up! Thanks for sharing that.

@BigRig are you holding your threads tight when you start?

@Revv Up @John

I got my machine sewing again. I may not have had my threads pulled tight enough on the restart of this and that is probably why this always happens to me when sewing vinyl and foam especially when I have to restart half way down a panel. I just cant seem to get my bobbin thread pulled enough unless I let out about a foot of thread. My machine was whacked last night no way I though I could get it sewing thanks for the advice guys. It saved me about $250.00 easy.

Glad you got it sorted.

@John, for now Working on my course and into the Tuck and roll man it must have taken a while to learn that. Do you wear glasses normally?

Yeah lots of practice @BigRig I wear my glasses a about %50 of the time just not usually in the videos.

@John,

I thought you were trying to break some needles ha ha

hahaha. No not the case. haha but technically we should all be wearing safety glasses while sewing. But we all take out own risks....
