insole stitcher needle size 45x230 = which thread?

[Bert51]

The needle hole size is 230, which should handle thread that is 346 (T350) [Tkt 8] , but if you need heavier I have 328 needles with a hole size of30/330 which should handle thread sized 554 (T600) [Tkt 5] .

Thanks Bert. You have given me the keys to better understand the challenge. I had found that Toledo webpage before but I could not understand how to use it. The .828mm needle diameter of the 330 needle does not suggest that it can sew with 1mm thread. I do not know if the RC-32-4A  will take the needles you describe. I have emailed Robin Industries again - I'll share their response here. Thanks again.

ah, the SK - not cheap but also does a rope stitch that looks bulky on the midsole - my hand stitching uses a 2 x 1mm waxed thread bypass knot, the Robin RC-32-4A  does a lock stitch and that is my  preferred option. Jimi - the SK from about €1k and the RC-32-4A at €330 - I go for the RC-32-4A  - I want it to use 1mm waxed cord but I do not know if it can take it. If Robin replies I'll share it here. Thanks again Jimi. Regards Con

Well i´am sure you can get them a lot cheaper than €1K!!! Good luck with the machine Con.

Not only have they not answered you; they haven't answered my email or Facebook Messenger questions either. Methinks they may be (temporarily?) closed for business.

Hi, I just got a reply that includes " The thread you can use 6shares or 9shares , both are ok, the 4A is stiting the upper soles, " = confusion...

I reckon she means 6ply and 9ply but that does not actually give the thread diameter... It may be the fault of googletranslator!!!

I will reply with shorter sentences...

Thx Wizcraft - the hunt for accurate info continues...

Oy Vey! That's one hell of a non answer. See if there are any social media user groups for Robin Industry. Maybe somebody somewhere owns these machines and can actually give accurate information.

Hi, will not tell me the thread size nor approved suppliers for thread but they have informed me that the cost incl post is now $380.... loosing confidence in their products...

Old Thread. I bought one of these. The needle size is DDX1 230/26. Same with the Sl 26 side stitcher which I also have. They both stitch well with .8mm braided kevlar. Some modification may be needed to use 1mm or above - I'm working on that. I broke the teeth on the bobbin shuttle driver thingy on the insole machine before I identified the problem. Replacement parts are on the way. Both machines have a much larger bobbin than the ordinary clsp  Sl 18 patcher.

I tried 1.1mm braided kevlar. It seems to get stuck in the needle hole. I switched to a 250/27 needle. The needle doesn't seem to be the problem. Does anyone know if you can grind out the hole to allow the use of thicker thread?

For those who are metrically challenged I believe 1.1mm is roughly equivalent to Size 554 / Tex 600 / Govt. 8-Cord . Not certain of .8mm but possibly similar to Size 346 / Tex 350 / Govt. 5-Cord ?

I have also ordered the Sl 28 which seems to be a superior alternative to the regular clsp patcher. The needle size is likely 28. It has a much larger bobbin  - 3cm diameter (well over 1 inch) and is capable of stitching through up to 3cm. Or so I am told.  That one should sew with 1mm thread or more straight out of the box. I think.

This is the one 32-3A Flat head shoe sewing machine http://robinindustry.com/product/274.html

 

For those who are interested in the insole machine I would encourage you to ask Robin about the RC 32 4A1 - which is the bigger brother. They have not made it yet but if enough people are interested they will. I am told they need to make a minimum of 100 units. It is capable of sewing through thicker leather and has a longer lower arm which would be very handy for larger boots/shoes.
