At work I have a number of Wenger music stands that date back to 1985. They are very good music stands but with age a problem pops up.

The connection between the desk and the T-bar stand is just four thin metal standoffs  that are formed  from a stiffener bracket welded to the back of the desk.  The thin metal over time with use, flexes and breaks away due to metal fatigue.

This repair simply replaces the standoffs using commonly available hardware. 

Step 1:

The new parts for each stand.  Save all the old parts from the stand.

4-1/4” threaded rod coupling about 7/8 " long
4-1/4" x 3/8" truss head screws  (wide flat head)
4-1/4" flat washers

The photo shows both the new parts and the old parts together.

The tools include 
hammer
drill
1/4" bit
socket wrench to fit coupling (standoff)
pliers
center punch
screwdriver
vice or clamp

Step 2:

The first thing is to remove all the parts from the back of the desk.
Then using the pliers break away any remaing standoffs.
then hammer flat any remnants of the standoffs. 

Step 3:

Now place the T into the desk-bracket and center.
Then be sure to square up the desk and stand.
Using a T-bar bracket as a guide centerpunch the standoff locations.
with the 1/4" bit drill the holes for the truss screws 
de-burr those holes

As I have a number of these to do I created a plywood template to mark the standoff location.

Step 4:

Install the truss head screw from the front of the desk.
Add a washer, then screw on the standoff.
Tighten all of these very tight.
At this point i use my template to make sure that the top of the standoffs are properly located
You may need some minor adjustments

Step 5:

The original back bracket had quick threads  for the screws. We now need to drill a 1/4" clearance hole where those threads were.
Put the bracket in a vice or somehow secure it so that it cannot spin as you drill this hole..

Once that is done we can reassemble the desk with the T-stand
<p>DougW2, A hose clamp on the chrome pipe will stop the stand from slipping dorn. It acts as a stopper.</p>
<p>I have done the same repair and it works great. My problem is I have several stands that will no longer stay in place. Is there anything that can be done for the Wenger stand that slips down?</p>
I use a large binder clip, or bulldog clip any clamp that fits the post.<br> <br>doesn't fix the problem but it works, use 2 for heavy loads
Cool! And, De Ja Vu. I had the same thing happen to several stands and did this same repair a few years ago. I can confirm it works well, though I had some trouble aligning things when I did it.
Having the plywood template helps with that aligning process. My biggest problem has been when the welding students have gotten to the stand first.
