Incredible build. Also, thank you for translating your website to English.

Joe, Thanks again for the motorcycle rack idea. I've attached a picture of the completed rack built to haul my KTM 640.

Hi Explorer,

looks solid.

Have you connected your construction to the frame of the truck or at least directly to the support frame of the cabine? Hope so, because I unfortunately read from several guys who thought their construction is strong enough and the bad or dessert roads ruined sooner or later due to the permanent vibrations.

Joe, There are two square receivers welded into the frame which square tube frame bracket slips into. Once inserted each receiver has lock bolts to hold it in. On the back of the cabin I've reinforced an area for a bracket that connects the motorcycle rack to the cabin. In addition to those, I leave the hoist cable connected with a small amount of slack as a safety line if any part should fail. If you have any suggestions beyond what I've done I'd be interested.
I see that you are in Germany. I have been unsuccessful in finding some metric brass fittings here in the USA. I have an air tank with a male 12mm
1.5 fitting that I'd like to find a female coupler or "T" to connect an adapter
from 12mm 1.5 to 1/4 NPT. I've tried every US source I could GOOGLE. Is there a source in Germany for such fittings. I can find the adapter, but not a fitting with female metric threads. I'd prefer a "T" fitting, but could make do with a straight coupler. Any help from Germany would be appreciated.

Hi Roger,

sorry, I am not too familiar with fittings and therefore have posted your request here.
Hope there will be someone who can help you.

Hi Roger,

Mike / Freeclimber, member of the forum above and with two posts to that issue just gave me a call:
An adapter from Metric to Imperial seems to be not available.

He has a friend who has his own company and can build something for you in a professional way. BUT this adapter can / should normally be built by everybody who can braze professionally by brazing a metric and an imperial thread together.

OK, in case you want to have it from a German company the handling is as follows: Pls. prepare a technical drawing with dimension (depth of female thread, 1/4" thread female or male??, which length, sealing how [rubber, ...]).
The drawing can be just by pen, scan it and send it either to me by email or directly to Mike.
He will then pass the drawing over to his friend who will make an offer.

we regularly have to do international plumbing in stainless steel

we just use for example a 12mm thread to 1/4" Tube and then 1/4" tube to the desired thread.

In brass I'd just use a solder fitting on both ends and a piece of 1/2" tube soldered in the middle.

most solder fittings are loose fit ie 12mm fitting and 1/2" tube..drill to suit

Thanks for all the suggestions. I thought I'd try the easy route first, figuring if I can buy NPT brass "T" at any automotive store in USA, a person in Germany could do likewise for the same type fitting with metric threads.
If I can't buy an off the shelf fitting I'll make one by cobbling two together or use the test valve that I took off, turn it down on a lathe and re-thread it on the male end with 1/4" or 3/8" NPT and go from there. Thanks again to all.
