With all this time on my hands I have been cutting, welding and designing.

The main drive behind this rotisserie innovation is I despise using C-Clamps on a rotisserie to hold the playfield. They get in the way of the rotisserie frame if they are not flush, they snag on everything, and they will leave marks on your new playfield if they are not protected with some type of pad. The footprint on a C-clamp is just too small. Plus now my C-clamps are all used up on my rotisserie and can't use the for something else. I also wanted something integrated and dedicated to my rotisserie.

So I decided to make a better clamp system. I think I hit the nail on the head here. This is just the one side. I may do one with one longer piece for the back of the playfield. The only problem I can see with a longer piece is it will possibly interfere with mechanics on the playfield. That is why I made these fairly small.

I also will be adding some type of material to the clamp so it will not scratch the playfield once I paint or powder coat them.

Any thoughts/input on these? Actually I am a bit surprised with the talent on this forum that something like this has not been done before. Or maybe it has I have just not seen it.

All these parts are from my local Ace Hardware. HD also has all this stuff as well.

Exactly, I need to paint it or Powder coat it first. Chrome would sure look nice.

Yea, wise words. I think Red paint might do the trick.

I cannot stand the C-Clamps either.

No plans on making and selling sets. If I had the ability to mass produce them I would. I just do not have the needed equipment to produce large amounts of these.

Got the parts I was waiting for today and the new Rotisserie is in place.

You can see my old Rotisserie (painted Red, that uses C-Clamps, yuck) I made last year in preparation for my High Speed Playfield swap. It was my first off rotisserie. The new design is essentially the same with a couple small revisions. Off to the paint shop now.

The new clamp system is in essence similar to my old round clamp system however this new clamp is 100 times better, stronger and much cleaner. Along with no need for C-Clamps to hold the playfield I am quite happy about!

In full Disclosure. The new friction green rotation clamp system is borrowed from @wrd1972. He is selling a quality Rotisserie you can see here.

Painted, felt added and a couple minor adjustments and it's doing the job.

Put in smaller diameter springs for more grip on the playfield surface

Thanks, Works great.

It will not fit on the back end of a playfield if there is a back board on the playfield. I need to spend a little time to make a work around for that.

It is a pain in the butt squaring off for the carriage bolt. I did do it on the original design with the knob on the small clamp side. I did not square off the small clamp yet but will be doing it. the spring did give some tension. The carriage bolt does bite enough to hold it from turning. But the best and cleaner route is to square the hole for sure.

The collar in the first design was there to elevate the knob making it easier to grasp since it was close to the long angle iron.

monkfe suggested flipping the bolt putting the knob on the other side unobstructed. When I did that the knob was unobstructed so I did not need the collar. I did put a washer below the Knob though.

Also find the smallest diameter spring that will fit the bolt. Gives more space for the playfield to be gripped by the clamp. I used a fairly stiff spring, holds the clamp open much better.

Nice. I really like the functionality. It is so much better than C-Clamps. Post a pic when you get a chance. I'd like to see your work.

Ok, will be looking for the pics.
