[Amps] Cheap Right Angle Drives

[qrp73 at talk21.com]

Thanks to all who offered advice.

I have played with this drill right angle drive and find it to be excellent. Very Little backlash and very large bevel gears. The Shafts are 10mm od. You can actually use the drill chuck as a coupling, great for quickly checking a vac variable when you play around with them. 

I doubt you will break one of these in amplifier service. You unlikely to bind one of these since the whole plastic unit fits the gears exactly, the gears would never jump out of alignment. They very smooth in operation. I can get 3 for the price of one Cardwell unit so for me the economy is worth the discovery.  The Cardwell unit does look very compact although the picture on the web page is very poor. These units would be more usefull with larger amplifier projects rather than desk top units.

This drive is so good i am thinking about using a battery operated screwdriver ala screwdriver antenna to drive a roller inductor or vacuum variable.

Thanks
Greg
