I've posted pics with several different Saitos running on my test stand over the years, but figured would describe how it developed:

I had to make mine self contained as there was no guarantee I could find a table or deck to clamp the standard setups to.I lucked out when we had some waste 6061 alloy could machine to form the deck, as well as material to form the uprights and clamps. Spare tooling bolts used to hold down options to a mill deck tighten the clamps along the slot to fit everything from a COX 049 mounted to an angle iron adapter plate, a Fox 30 stunter with the baffle plate linked to the throttle, all the way up to a Saito 180, (so far). In the last year only issue was with a 46 I did for my friend that had a Pitts muffler. I pulled a stock muffler from spares and was able to set up what was a way out of tune carb after the standard treatment, (new bearings, etc.).

The frame itself was from another setup purchased so long ago cannot remember the source. I welded 4 T-rods used to anchor into the ground from stainless to avoid corrosion, (found only 2 necessary, but these pics show screwdrivers as the ends were getting painted yellow) and they have held up now for almost 2 decades without issue. I do have to bring a claw hammer to sometimes work them back out of hard ground.

I adapted two nosewheel steering mounts and a bent rod for my throttle, a wheel collar and spring against one to add a friction stop. That is hidden under the tank holder spaced off the deck for clearance and to adjust height to match the inlet fittings on most 2-strokes, (the centerline height doesn't match that of the uprights, but does not seem to affect 4-strokes that much). A steering arm also forms the lever for the rod up to the engines, using another spring loaded thumb clamp in the outer hole to adjust the 2-56 wire. That allows for infinite adjustment and changes to reach different carb setups.

Only mod early on was to reverse the throttle to the left hand side to avoid the exhaust. Can't believe didn't think of that during assy, but it showed up early with hot, oily exhaust exiting right aboot where your hand would be.Another future change hoping to accomplish is a taller pipe to raise it up to make my aging knees complain less. Still looking for alloy as it makes it lighter and easier to carry.

For anyone thinking of anything similar, I'm sure this design could clamp to a table, and there could be a servo operated throttle, as well. I just thought making it completely manual kept things simple.

ps. Unfortunately went looking and found the latest media wipe lost a lot of the pics in my engine folder. Included is a link to the initial run of a Tecnopower 7-cyl radial I built last year.

Hope someone else can find these ideas useful.
