Is Hilux available with gas or diesel, or diesel only?

Several foreign auto manufacturers sent diesels to the US in the 2000s, some still do, but not as many. Perhaps the emissions for diesel is too strict... the Volkswagen scandal probably added more attention to the incoming diesel autos as well.

Diesel's over here are not what they used to be. We have one left in the fleet that does not require DEF. Do you have to use DEF over there?

I started another thread about the motor drivers... same ones you are using. I am a bit lost on the configuration. I got it turning a motor, but it's super slow...

Yeh, we have a DPF that there is a class action against Toyota over. Has not bothered me yet. We only have the diesel option now. They do a petrol in some markets. I have a client in Bali with one. I think the Caribbean, Mexico and South America get a petrol.

Hmm, back on topic but I found this DIY design
www.woodweb.com/galleries/shopbuilt/posts/95.html

I found the bast gate on Amazon for $40
www.amazon.com.au/POWERTEC-70227-Aluminu...e-improvement&sr=1-1


Actually looks quite promising... and reasonably priced.

I saw the one from amazon when I was looking for parts... but figured it would be easier/cheaper to add the gates onto the square tube ports than adapt these. Home Depot sells these for $20 online.

This one is available locally for $15USD ... I almost went with it.

If I was building the duct from scratch (again) I would definitely use circular tube for the ports... there are tons of items for sale to fit the circular duct. We had the square left over and so we used it... sometimes that comes back around to bite!

Most of my searches led to woodworking cyclone dust collectors, but eventually I landed on Donaldson Torit's website for high temp, high load, dust separators. These are out of my price range but they gave me a lot of ideas.

In the end I bought my solenoids, copper tube, and most of the fittings on Amazon. The actuators and some harder to find fittings came from Allied Electronics.

I ordered a Teco Westinghouse 5HP 3 phase VFD on ebay, should be here by Tuesday or Wednesday, for half price... it must have fell of a truck somewhere in New Jersey. I am going to use that for the motor 'starter' ... I wont use most of the features on the VFD, but it will be easy to interface with LinuxCNC and also gives the ability to soft start the motor.

I have been reading the the setup guide for pncconf today. My goal for tomorrow is to get the motors all spinning properly on the old 4x4 table. At that point I may switch over the LinuxCNC setup to the big table aka 'The Mark I' ... gotta take the leap of faith at some point!
