Give a look at temporary lock tire, another option is those removable double face tape

I went through a similar challenge with a Sigma 150-600 C. Tho not as heavy as the Sport, still an issue. I was using a gimbal and a ball head, but after watching a Thomas Heaton video, I liked his idea of a pano head. Bought a Acratech pano head and really pleased with it. I called Acratech and asked if they ever sold cosmetic rejects that were functionally good. To my surprise, whoever I was talking with said, “yeah, got one in front of me, can’t tell what’s wrong with it but I’ll sell for $150 off.” Sometimes we get lucky.

Whatever plates you use you MUST use high grade screws and TOOLS for applying the proper torque - hand tightening will be problematic .....always !

I like it. The collar is easily removable, providing protection from the lens. I haven't done a drill and tap since metal shop circa 1962. Sounds like fun.

I found, what I hope will be the best solution. - a machined lens collar, arca compatible $60 solution shipped from across the Pacific.

I tried most of the other suggestions over the years and this method though a bit extreme was the only one that has worked 100% over the last 60 yrs, because the with the length of the lens even a slight bump would cause the screw to loosen. In fact back in the 70s I had a lens that came two holes in the foot, soooooo It's not really my
idea.
A #7 drill bit and a 1/4-20 tap only cost a few dollars.

So what torque setting do you use?

I suppose a Manfrotto 516 fluid head would work, but I prefer a gimbal for getting more fly-over shots. I use a Manfrotto 393 gimbal with an Arca-Swiss clamp attached to the Manfrotto lens plate held on with 2 screws. It works well and costs around $200. The nice thing about the G2 is you already have the Arca-Swiss dovetail on the tripod collar -

That should cure the problem of coming loose but will limit the amount of movement to balance the lens, I use a long plate long (6"-7") plate on my lens. You can buy a lot of drill bits and taps for $60

Now that sounds like proper Torque for a 1/4" bolt that has a reduced diameter just under the head

Yes, that collar is a real plus. In all honesty I probably should give up this large lens and get something more practical since I do not photograph moving wildlife, BIF etc. because of all my health issues. But I was thinking that a fluid head would be good for either my Fuji X-T2 or D750 with my smaller lenses since I tend to shoot mostly landscapes and closeup stuff. The Tamron 24-70 G2 stays on my D750 and the kit 18-55 stays on the X-T2. If I did not have all these health issues and was younger, I would use that large Tamron 150-600 more than I do now.

That long lens stabilizer looks really good. Thanks
