The Dreaded Timing Issue

[Tree Reaper]

The four pictures below indicate the position of the needle and feet with the take up lever first at the top and second at the bottom going forward.

The third picture is with the take up lever at the top and the fourth is with the take up lever at the bottom in reverse.

It appears to me that the inside foot is on the feed dog before the needle. Use the appropriate Allen wrench to loosen the Allen head bolt on the crank rod behind the head. Rotate the wheel again to bring the needle down, until it reaches the hole in the feed dog. Make sure the inside foot is down all the way (use your fingers to move it down), then clamp the bolt tight.

If this doesn't fix it, the screw that holds the motion rods together, at the upper-rear of the machine may have been loosened by your jam.

Thanks Wiz, I was out of the house all day and Bob called but I missed his call.

I'll give him a call back tomorrow.

I'll have another quick look at it tonight but I'm too tired to turn any screws but I will get into it over the next day or two.

I just had a closer look at it again and it appears that the needle hits the hole at the same time the inner foot touches down.

Well, I was looking at the feed dog and it was below the throat plate so I pulled the race out and tried to raise it but I can only get 1mm maximum height before I run out of adjustment so now I'm thinking the feed dog got bent.

I'm guessing there should be at least 3mm or more of maximum height adjustment above the plate when it's raised above the plate.

It's close to 1.4mm now which is the recommended height so I'll give that a whirl.

I most likely need a new feed dog.

I just ran a stitch and a back stitch, looks like it's working again but I'll run some more scrap leather through it later.

[Wizcrafts]

Are you sure it is bent? Mine only protrudes a little over a silly millimeter. If it really is bent and if you got the blanket foot set with your machine, you can swap feed dogs until you get a replacement for the bent smooth one.

[Tree Reaper]

I can't say for sure Wiz without having another to compare it with but considering you seem to have the same clearance maybe it isn't bent and it just got forced down although the screw wasn't loose.

[Tree Reaper]

Well, that was short lived.

I ran a few more trials last night and every one failed on the back stitch.

Bob talked me through centering the feed dog and needle and that didn't help so he suggested I drop the feed dog to level with the throat plate and that didn't work.

I think he's at a loss for this failure and I haven't got a clue so I'm wondering what to do next?

I don't understand why it works sometimes and not others. But I don't know Jack about these new machines. I got my top thread caught in a wad down in with the bobbin thread and thought I'd never get it out, but it did, and went right back to working. How can they make something so simple really when you think about it so easy to mess up? Needle goes up and down, dogs move at the same time. If it was 75 years old Kevin I could help, but not one of these. All I can offer is IF IT'S BROKEN, FIX IT Thought maybe I could get that part of it out of the way for you. Maybe Wiz will have some more ideas. c

It is time to get out the schematics for your machine and compare notes. Do you have the exploded view and all the timing details on 8.5 x 11 pages?
