Window knobs

[Rust]

Hello
Does anyone have a source for aluminum knobs for window opening levers. I want to replace the cheap plastic ones that come on the trailer.

Thanks George

Unfortunately, the metal knobs are now history.

The cheap plastic ones are all that is now available. You might be able to find some on a wrecked Airstream, or in the forum classifieds.

Silly question.
I see you are a machinist. Why not make your own out of billet aluminum?
There may even be a market for a good replacement of the plastic units.

I have seen two drawer nobs, used with a short threaded shaft, as window nobs.

Do you have a photo of the knob you are talking about. I could have some made.

TG you are right. I was going to make my own but I thought I could source them cheaper then making them.
Some times the time involved makes sense to buy them. But if they are not available I will make my own. I will make them out of stainless drill and tap a M4 set screw in them to secure to to arms.
I have made a few things now for the trailer. One being two new awning claws,Two stainless steel bumper locking pins, Aluminum gap spacers that enclose the rear bumper so it is more secure from mice or whatever from moving in.

Thanks for the help every one.

Rust-

Stainless sounds great. PM if you make extras ...

I used 1" dia. aluminum and knurled it. If doing it again, I would use 3/4". The 1" is just to big and the blinds catch on it going up or down.

Looks easy to make what type of threads are on them. Might be able to find something off the shelf at mcmaster.com.

The stock set screw is a 6/32 and the bore is a 0.266 or 17/64" I used 8/32 set screws just to have a little more bite

[perryg114]

So it is just a hole with a set screw holding it on the shaft? Something like these.

That is correct. Those stainless steel ones do look good You will have to drill it out to 17/64", if same as mine. Also, if you want to be able to open all the way up, you might need to bevel some on the 5/8" part. Here is another photo of what I had to do so the windows would open all the way. Sorry the photo is a little out of focus Mine are 1/2 " thick.

Thanks for the picture.

I looked at the misumi web site and didn't find any and forgot to look at McMaster-carr.
The stainless ones works out to $95.00 for 14 pretty cheap considering the labour time to make them.Things are cheap when you make thousands of some thing.
I'm still toying with making them myself and profiling them on the mill to the shape of the plastic ones then us a M 3 or M 4 set screw.
I will just make a small holding fixture to hold in the vise.

But $95.00 versus my time McMaster Carr sounds better.But since it is winter I have time to do it.

Again thanks for the feed back.

Those plastic knobs are available that have a allen screw built in to hold it in place on the lift arms.

You can easily paint them any color you wish.

And, they are not expensive.

Thanks for your input I like reading your replies to questions asked here.
But I do like the aluminum or stainless look.

George.

I agree with your choices.

But when a persons first choice is not available, then the second choice usually fits the bill and becomes acceptable.

I agree with you there.
