For some unknown reason the front stays on the shelves no longer sit well within their plastic guides.
An extension of the powder coated wires needed to be made. Welding was not possible due to fumes from the powder coating and rust of the steel shelves.
The solution was short aluminum tubing extensions.
Step 1: The Lack of Tolerance
This shows how close the unladen shelf is to coming adrift
Step 2: Tools and Supplies Needed.
A pipe/ tube cutter.
A sharpie for marking (not shown below)
A vice. (Not shown, I never show off my vices:-) )
Step 3: Marking and Cutting
Adding the depth of the plastic channel mark for the centre of the cut.
Step 4: Cutting
Some hints to make this easier :-
Hold the tube in a vise. It is important that the work does not turn.
Use something soft in the jaws of the vice to save marking the tube.
Only tighten the cutter a small amount each time.
Rotate the cutter toward the back rib of the tool as this makes scouring the tube easier.
Rotate the cutter until it turns freely.
Then tighten it a little. Repeat this until the extension piece comes off.
The trick is to work slowly.
Remove any burrs from the cut end.
Step 5: First Extension in Place
Repeat the process until you have cut sufficient extensions for your shelves.
Step 7: Problem Solved
Overload the shelves as normal :-) and they stay on place.
Hooray! Problem solved.
MMmm A freezer is a big box, would I be too lateral to enter it in the box contest?
