POM-C has high mechanical strength, stiffness, hardness and toughness. Excellent resilience. Good creep resistance High impact strength, even at low temperatures. Very good dimensional stability (low water absorption) Good sliding properties and wear resistance Excellent machinability Good electrical insulating and dielectric properties Physiologically inert Not self-extinguishing

Using STAUFF HEAVY clamps to secure the radiator with insulator.

In Europe Hydroflex clamps are easier to obtain.

Cutting 485 lbs aluminium tubes

How to fit metric tube sizes?
For example diameter
Tube 1: OD=60mm /ID=50 (2,5'' /2'')
Tube 2: OD=50mm /ID=40 (2'' / 1,6'')

This size and lenght does not fit into my lathe, so I have to think about a solution:

WOOD TREATMENT IS THE SOLUTION
Use a woodrasp and a sander to remove 0,3mm (0.0118'')

Inserting long heavy tubes by ONE-MAN
is done with the following technique:
Make sure the tubes are smooth.
Next step is using heavy pipeclamps and guy wire tensioners as show on the picture right.

Inserting smoothly and easy with no slack within the tubes. This method is solid, permanent and makes the tubes mechanical and electrical tight.

Using a flamethrower when for ultimate mechanical strenght.

Fixed 2,5'' and 2'' radiator tubes

One lenght (1m= 3,28ft) off POM-C comes in between the radiator center.
