just to inform here also. My plan is to ship the product by 1st of June. Thats the plan at least

Just to give you a sense of logistic

1. One company is importing PA 46 for me
2. One company for CNC
3. One company for laser cutting steel plates
4. One company for making tensioner spring
5. One company for lathe pieces and one pin needs to be heat treated
6. One guy to weld steel plates and to assemble everything

Probably I missed someone ;)

Mirko, you sure know how to pull out all the stops with your designs👍

I get how hard these are to make, and I for one appreciate you aiming for a best solution rather than the easier solution.

I started production of tensioner system. Already paid in advance to some shops. Hopefully everybody in production/supply chain will keep up to agreed delivery dates.

I will contact now people for advance payments. Majority of you want to pay 100% in advance. But 50% is ok also.

One more thing

There is 10 sets ordered. I am making 10sets. Just to make it clear that there will be no surplus left. There is probably several more days to order before time runs out...

it seams the last one is also gone in last hour.

PA 46 is in the house. Finally. At the end it was sourced in white color because of different supplier... Ensinger instead of DSM. I attached specification of sourced PA46

Bummer Jerry.  Quality often requires patience.  I’m very eager to have mine in hand soon.

Well George, there is always the next time  ;) Gotta try to get it together for Vintage Days and I won't have enough days left. Who knows, if I have to order more little parts I won't make it anyway  ;D

One good news and one bad news.

Everything is assembled and ready for shipping for the last 7 days.

That brings me to a setback....

I was not feeling ok with white material polyamide. Simply it was not looking/feeling right under my fingers like PA46. I sent samples to laboratory to ease my mind 10 days ago. I've got results yesterday and it is not PA46 it is ordinary PA6. I new https://www.dsm.com is making white PA46(TW371, TW441) specially for cam tensioners so I believed that they sent us that material.

I am not sure did material vendor tried to trick me or somebody from Netherlands tried to trick them... Not important. Got my money back and CNC shop agreed to help me by redoing the parts because they ordered the material. I lost some money but also not important.....

I ordered  original DSM red PA46 material today directly from confirmed supplier from Germany. I used their DSM red PA46 in original prototype of primary tensioner. Material will be here next week. CNCing is scheduled for 12th of July.

Sorry for delay and inconvenience  and please be patient. You can guess that I did not take this easily but it is my responsibility. I hope I will ship tensioners on 20th something of July....

Really professional !

Many companies need that feeling for quality which is feeling for it backed up by action, not only powerpoints talking about quality, Lean Six Sigma year after year.
