is this the tail wheel you are having trouble turning right?

and did you mention the wheel turns easy till the actuating bar is bolted on the top?
if all above is true,,,,, there may be a missing washer under the actuating bar,,,,, or the housing may be a bit too tall.
this is the wheel I am using now and wish I had changed from the pizza cutter wheel much sooner. I love it. and even more so since I put in better bearings.

I like that. Do you know the inside diameter? I'd like to see if that will fit onto the male shaft coming from my rear boom. What does that one cost? Travis at Kolb told me the new tail wheel with 1" wide wheel is $300+ dollars but he said it's a whole new one that needs to be put on the boom. The one in your picture looks like it might slide right on my shaft. Thanks for the picture, I can finally see one!

If the wheel is not exactly vertical ,or leaning when stationary,it will give you a fit.The tail spring must be tight in the support tube and the rest of the assy tight on the spring rod.If it can move off of dead vertical it will be easy to steer on way and almost impossible the other.The rods get sloppy in the tube and the bolt hole elongates letting the rod twist.I cured that issue on my Mk3 by clamping the rod in the tube G.Aman

I mounted one of those wider tail wheels really easily on my FireStar. The inside diameter of the bearing is 5/8" and the original shaft on the assembly is 1/2", so just needed a short length of 5/8" tubing with a wall thickness such that it would slide over the original shaft. Found that in the offcuts from someone else's building project. Notched out one end so it would fit over the support tubing, then a 3/16" bolt to secure it. Could weld it if you had access to a welder. Works a heck of a lot better than that pizza cutter which finally collapsed.... The new tail wheel is Aircraft Spruce part #06-03500 $23.85.

More on tailwheels.
That tailwheel I mentioned is the replacement wheel for the 'Homebuilt' tailwheel mechanism. I think that's the same mechanism that Kolb offers. If you're getting the whole mechanism it's worth getting it from Kolb rather than Spruce, cause the hole for mounting on the tailspring is only 5/8" in the Spruce unit, while we need a 3/4" hole. It's very difficult to bore out to size because of shoulders on the housing so it can't be chucked in a lathe. Last year I made the mistake of ordering the Spruce unit when Kolb was out of stock. Cost another $140 for a machine shop to make up a special boring tool and do the job. Wouldn't dare try to just drill that out unless you could run the drill super slow and hold it back from biting into that big pilot hole.....
Also, I found that the breakaway feature was just a nuisance unless maybe you have differential braking. Several times it broke away when taxiing, and couldn't get to re-engage without stopping and getting out and doing it by hand. Finally ground out the mechanism so that it stayed engaged. So might as well just have the original Kolb mechanism but with the wider wheel, as I've done this year. Saved $300 and a couple of pounds this way, and sure don't need any more weight way back there.
The steering springs on my aircraft were way too soft, especially with the wider wheel. Got the stiffest ones that were the right length that I could find at Ace Hardware, and that's better, but still mushy. John H - How can you hook up 'compression' springs there?? When I get back I think I'll use 3/16" bungy cord, looped around as many times as necessary to get the right strength. Done that before with another aircraft and I liked it better than springs....
Just my experience, for what it's worth.....

p.s.- How do you load photos to these posts?? The one that I tried to load with the previous post didn't seem to work.....

I use compression springs like John uses. I think I got them at Aircraft Spruce. I use four of the attachment things (technical term) to attach my springs. They look like the rear ones that John shows in the photo, seems like I got then at the same place. They install like the safety rings but are much stronger and don't come off in deep grass. I installed them as tight as I could but they still have a bit droop to the chains. The compression springs allow the tail wheel to snap to the direction of landing roll when I touch down without stressing the rudder assembly but allow for MUCH more positive control in cross winds.

Didn't look at my photo long enough before I sent it.
I used carabineers to attach to the rudder and "normal" tail wheel spring clips to attach to the tail wheel.
One could easily bend up to strong "s" hooks to do the same job for nothing.
