Default Broken Al. Black Widow tonearm.

Well the carbon tubing arrived but its too large. Thought I might look for Al. Tubing but might be a waste of time. I have looked for ages for one of these arms but kept being out bid so.
Does any one have the arm carbon or Al. or tubing that would be about 1/16th of an inch to fix my problem?

Default Broken BW tonearm.

The aluminum BW tonearm is a two piece unit which is broken in the outer section. So it is the earlier version not the carbon one. It has the wires and the two broken sections. Trying to think of a fusion but the aluminum is really thin.
I live in NY. Tried to contact "Audiogami" but no luck.

Thank you sreten I appreciate your suggestion. I think I might take the broken end (the part with the headshell) with me to the hobby shop. Another thing what to do about the fixed headshell? Maybe just a band to glue the two pieces together? The arm is incredibly light like an hairs width. So keep it coming.

Hi,

The headshell appears to have some form of attachment screw underneath.

Another option is a tube you can glue the aluminium tube inside at either end.

Another option is using something like "spraymount" and rolling a new
arm tube out of aluminium foil, the damping should then be very good.
(Use a lightly greased knitting needle or similar as a former.)
Go somewhat thicker than the original tube thickness, obviously.

rgds, sreten.

Hi,

I just rebuild this kind of tonearm recently. Follow theses steps.
- Dismantle the arm from the base. Just remove the screw on both side of the blade/bearing
- Try to dont damage the wire
- Remove the small screw on the headshell. Heat gently the front tubing to remove the headshell (the glue come to melt with heat)
- Remove the small screws (2) at th ejunction of the both tubing and the other one where the bigger tube is fix to blade.
- With heat unglue the tube from the blade and also unglue both tube (or the section one inside the other one...)
- Go to hobby shop and buy two aluminium tubing where the diameter is close to the original (try to find an hobby shop where you can find these products: Retail Merchandisers - K & S Precision Metals: Full Line Metal Specialists)
- Cut the tubing to required lenght and rebuild your arm.

Good luck

Cyr-Marc
