Re: [drakelist] VA7TO 2-B: Lubricants?
Darrell Bellerive <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- I received a personal email from Bill Frost, the Service Manager for Drake for the last 40+ years. He offered this information, reprinted here with his kind permission, with regards to lubricating the Drake 2-B receiver: "In regard to lubrication, we (Drake Service Department) always used a drop or two of 3 in one oil on the bandshaft detent, and a drop on the main tuning shaft bushing. Using a small bladed screwdriver, put a drop of oil on the end of the screwdriver blade and then you can reach those hard to get at spots, once you touch the area, the oil will transfer to the desired spot. Caution: Do NOT allow any oil to get on the dial cord or that section of the main tuning shaft. Also a drop on each end of the preselector variable and the tuning variable. If you use Deoxit or ?? on the variable controls, use it very sparingly. Just remember if it ain't broke don't fix it." -- Darrell Bellerive Amateur Radio Stations VA7TO and VE7CLA Grand Forks, British Columbia, Canada -- Submissions:drakelist@zerobeat.net Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --
[drakelist] VA7TO 2-B: Lubricants?
Darrell Bellerive <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- What lubricants do you use for the ball bearings, sleeve bearings, and other moving parts. I see in the archives that lithium grease is popular and Tri-Flow teflon Superior Lubricant has been used. I would like to lube the following parts: 1) Preselector shaft and ball bearings. I am a bit scared of this one as it incorporates a reduction drive and I am afraid that changing the friction may affect the reduction drive. 2) Main tuning capacitor ball bearings. 3) The two plastic wheels at the top of the dial string pointer mechanism. 4) The dial pointer. 5) The main tuning shaft. I will also experiment with slightly thicker washers to see if I can eliminate the fore and aft play. Perhaps a felt washer may do the trick. 6) The detent at the rear of the bandswitch. 7) The passband tuning control shafts. This one looks difficult. I will clean the bandswitch contacts with a foam swab and deoxit, and spray the pots and slide switches with deoxit. I will make note of the position of the pots before spraying them and return them to their original position. I do plan on doing an alignment and fine tuning them then. Anyone successful at cleaning the bandwidth rotary switch contacts? They appear to be completely hidden. Any tips, tricks, suggestions, or cautions on the above? For those of you getting tired of my many posts, this is the end of my weekend as I get Wednesday and Thursday off, so there won't be as many posts for the next 5 days. :-) Thanks to everyone who has offered advice and encouragement. It is much appreciated. 73, Darrell VA7TO -- Darrell Bellerive Amateur Radio Stations VA7TO and VE7CLA Grand Forks, British Columbia, Canada -- Submissions:drakelist@zerobeat.net Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --
