I had a twin cylinder air cooled electric start Petter hooked up to a 10KVA 240v alternator as an auxiliary power plant that ran pretty fast revs but did not belch much black or blue smoke except when I had the 3Phase power operating off it and then under load the smoke increased along with diesel consumption.
It was a good unit all self contained in a cradle along with the fuel tank.
I sold it with the property when I left the Atherton Tablelands in North Queensland 12 years ago.
I had a lot of Southern Cross Stationary engines up there mostly BDC and YBs. Sold them all as too large to shift.
Matter of fact in my toolbox I have a Knurled tube for  decompression operating, off a YB Southern Cross if any one is interested in one.
I believe they are like hens teeth to find.
Cheers,
Grasshopper Max

That would be a big help for you Scotty to have the tube.

Hi Cobba, I'm having trouble posting photos of the turntable as the files are to big and I can't resize them. If you pm your number I'll send them to you via the phone. Justin

Hi Justin, I received the pics thank you. I will build one a little bit simpler but this has given me some ideas.

Todays effort got me this far.
Welded the centre pivot bolt to the plate. Drilled and counter sunk the screw holes to fix to the transporter rails, made some saddles to hold the axles in place where I have routered the cross beam to recess the axles and finished all the welding on the axles.

Here's how the axles look mounted and the rear one sitting in place on the rails but not bolted as yet. Tomorrow I have to cut, drill and bolt the stiffening plates onto the cross members.

Today I got the front end finished and bolted on. Turntable seems to be ok and has plenty of turning circle for when the 'fat pig' is bolted down. All cross members have been plated and bolted and axles are bolted firmly in place just need some more coach bolts to hold the rear cross member onto the rails. This thing weighs a ton as is so it shouldn't break in a hurry.

Looking for ideas of the best way to attach a steering handle, any ideas out there?

This thread seems to be floating between Stationary Engines and General Discussion. Why is it so????

If you want to have a removable drawbar, a very practical way is to drill the axle mount timber for 12mm bolts or, whatever size you want and use eye nuts. Make the drawbar from square tube and locate it with round bar bent 90 degrees for a hand hold and drilled at the other end for a suitable pin.
