Singer 17-23 hook to needle clearance

Well - a #24, #25 needle is IMO out of the comfort zone of a light duty leather machine like the class 17. IMO #22 is the max needle size for a machine of this type. Yes, I know the manual says up to #25 but still. The very small spools do not hold much of the thick thread anyway, not talking about higher foot pressure you may need for a #25 needle.

my 2 cents

EDIT:

Seiko still makes clones of the Singer class 17 (their model is TE-6) and they recommend needles up to #19.

Beside of that - IIRC the class 17 shuttle runs in a race like the CB kooks and I do not think you can move the race further the to the right to allow a larger needle.

 

Yes, you're correct. This came to me set up this way but not working. No history, just the evidence of previous use. The foot pressure was cranked all the way down and froze up - I think we know why. I won't  go into all the evidence details, just wish the machine could talk. After a lot of work, I have it stitching belt leather and 1/4"  scrap with a #21 leather needle and #138 thread - hand powered.  I can tell that's all it will do unless connected to a robust power source. I think the effort to turn the balance wheel is a good measure of system efficiency and resistance.  Previous user had actually dinged up the shuttle race trying to get the hook out the wrong way. Dings fixed. The row of stitches at the bottom, ignore the rest.

Yes. I am a mighty Wizard and I uttered magic words, while opening the page first in WGET Online, after first removing the S from https. This rendered the HTTP page's source code. There wasn't anything suspicious. So, I simply removed the S and it opened as an http website. If the warning persists, simply use Firefox and ignore the warning, accepting the risk. It helps to have the Malwarebytes Browser Plugin installed too. Contact me privately if you need more info about Firefox and Malwarebytes.

Many of the current browser security warnings are due to an expired SSL Certificate that either is late being auto-renewed, or hasn't been paid for automatically by a cert buyer who has a dedicated, semi-dedicated, or VPS server account. It is easy to miss an email notice to authorize the payment if a card on file expires before the renewal takes place.

Thanks for the info Wiz.

Having had a look at Alexander Dyer's video and the ease with which a shim was added I can see no particular reason why a little can not be removed from the shuttle race holder at the rear. It is nice and flat. I was a little concerned about the needle plate movement around the 5 minute 40 sec mark but the dog foot and needle plate have no connection to the shuttle race so I assume the dog foot is rubbing the needle plate slightly but perhaps only because of loose screws.
