Bearing puller for pennies

Fix that fan motor

Posted By: Robert Nickels (ranickels)

 

Finding myself in need of a tool to remove a bad bearing on a blower from a linear amplifier I first tried the usual automotive type gear puller but it wasn't able to get underneath this small 5/8" OD bearing.   So I improvised a tool that took 10 minutes to make, cost a few cents, and had the job done in no time at all

The secret is wedges sold at the home improvement store for leveling doors and things that are made from a composite material.  Unlike the soft pine wood type, this stuff is rigid enough to pry off a stuck bearing.   Cut slots on a bandsaw and use a woodworking clamp to keep the sides from spreading outward, then just a few taps with a hammer should drive the wedge under the bearing and work it loose,   Stack two or more for larger gaps.

     Among it's early products, the Multi Elmac Company of Oak Park MI made marine band radios and other products for boats, including the Sea-Deep DM-1 depth indicator, the Sea-Fume SF-1 vapor detector, and the BC-1 Duo-Charger for 6 and 12 volt batteries.   Thus it's not surprising that the marine radio-telephone would be given a "sea" name:   the Sea...  READ MORE

   The Sonar Radio Corp.  of Brooklyn NY is a well-known manufacturer of Ham, CB, and Marine Band radios over a period of several decades, and it's products were always well engineered and of good quality.    But despite several attempts, it's ham radio products never really managed to excite hams enough to plunk down their hard-earned cash.   The SRT series of t...  READ MORE

    In 1958, the Multi Elmac Company was riding high on the ham radio waves.   The company had seen an opportunity to provide feature rich but affordable transmitters and receivers to hams itching to "go mobile", which was all the craze.   Instead of sticking a converter in front of the car radio like many competitors did, Elmac produced full-blown receivers that tu...  READ MORE

Mystery Transmitter

where's the copper subchassis from?
Category: Vintage Ham Radio
 I didn't set out to buy this homebrew CW transmitter, it was included in an auction lot that I wanted so I had to take it to get the desired item.   But even though I always like to see good quality homebrew gear, this one is just a mystery.Most of the transmitter, including 6CL6 oscillator and buffer stages and a 6146 PA are built on a sub-chassis that is clearly part of a com...  READ MORE

The Vector VR-50

last gasp from Swan/Atlas founder Herb Johnson
Category: Vintage Ham Radio
 Most hams are aware that Herb Johnson W6QKI founded Swan in Benson Arizona to make single-band SSB transceivers and then moved his operation to Oceanside CA where Swan thrived throughout the 1960s.   Swan merged with Cubic Corporation in 1967, and Johnson managed Swan as its subsidiary until 1973. Johnson founded Atlas Radio in 1974, with the assistance of Southcom International fo...  READ MORE

    I became aware of a few hams playing with a thing designed to receive digital TV in Europe on your laptop - a little plug-in dongle that used an RTL-2832 IC and sold for $20 or so.    Some clever fellows had determined that it could be put into "radio mode" in which it would generate an IQ stream over USB, and by writing to control registers in the tuner IC, it could...  READ MORE

    A while back I acquired a six channel HF transceiver made by the Radio Industries division of Hallicrafters, probably in the 1960s, called an SBT-20.    It is capable of 20 watts SSB or 5 watts AM (or CW with an optional board) in the range of 2-12 MHz and thus was probably aimed at commercial and light-duty military applications.   The radio could by ordered with fu...  READ MORE

    I'm always thinking about interesting combinations of equipment to try out on the air.   One day while rearranging the shack I was getting ready to connect my Globe Scout Deluxe back up with a Collins 51S-1 receiver when the LED (the energy-efficient version of the old light bulb) came on.When I first started playing with DVB-T dongles back in 2012 I wanted an upconverter so I ...  READ MORE
