S-85 (SX-99) IF cans alignment : What adjusting tool do I have to use to match the size of the cores' slot?

Emanuele Girlando All Messages By This Member #31553 Edited I am approaching the last task in my S-85 refurbish project: Alignment. For those IF cans I cannot find the right tool mechanically match those cores' slot: it is too long and too large. I own these tools, none of them fitting: ? I see two alternatives: 1) buy one (can someone provide me directions on where to buy and exactly what?), or 2) build one (preferable - can someone provide me the slot size specs?). Thank you very much guys. Emanuele. ? ? ?
don Root All Messages By This Member #31554 Edited 开云体育 Emanuele, about when did you buy these tools? Likely these are more recent ones made for newer, smaller cores. I recall looking into cores a year ago and there are many shapes and sizes now. The sites specializing in vintage radios probably have the ones you need. ? ? toggle quoted message Show quoted text From: [email protected] [mailto:[email protected]] On Behalf Of Emanuele Girlando via groups.io Sent: Monday, January 27, 2025 11:45 AM To: [email protected] Subject: [HallicraftersRadios] S-85 (SX-99) IF cans alignment : What adjusting tool do I have to use to match the size of the cores' slot? ?

Emanuele Girlando All Messages By This Member #31555 Edited Yes, they are modern stuff.. what i miss are the old tools.. so the question is: what are the slot measures of the Hallicrafters IF cans (p/n 050-30024[2,3]) old cores? ? (this picture, showing the slot, comes from ). ? So, can somebody tell me what to replace the question marks with? ? ? Emanuele. https://egirland.blogspot.com ? ?

One of these might fit Are you intending to make your own tool?? Use wood or plastic.. you must know that already I am not the expert, so ??others must know better ? toggle quoted message Show quoted text From: [email protected] [mailto:[email protected]] On Behalf Of Emanuele Girlando via groups.io Sent: Monday, January 27, 2025 3:49 PM To: [email protected] Subject: Re: [HallicraftersRadios] S-85 (SX-99) IF cans alignment : What adjusting tool do I have to use to match the size of the cores' slot? ?

Paul Lemmon All Messages By This Member #31557 Emanuele, ? The last project, wow. ?I still have about 9 Hallicrafters on the shelf waiting for the dust to be blown off. One is a SX-99 so I may have to also make a tuning tool. ?I’ve had to make a couple for some other radios I’ve restored. ?Think about using one of your existing tuning tools, cutting off the existing end and reshaping for the needed slugs. ?Be sure to use one which will go into the IF can and which is not needed. ?This has worked for me and eliminates the need to find the correct diameter wood or plastic. ?Also if the slug won’t turn apply a small amount of heat from a low heat gun or SMD desoldering heat gun to loosen any old hard wax inside. ? Good luck and be sure to let us know how it goes and also the final dimensions of the tip. -- Paul NV6B
D. Platt All Messages By This Member #31558 Edited 开云体育 For what it may, or may not, assist... I pulled my late SX-99 off the shelf to see the IF cans.? They are slot, vice hex tuning slugs.? I then looked through about 100 tuning tools from Xcelite, GC, and others only to find the exact one needed.? The required tool is a rectangular bit, vice a thin flat blade. The correct tool is 1/8 X 1/16.? The "normal" slot tool is approx. 3/32 wide and 1/32 thick.? I have used the "incorrect" plastic or Delrin tools, in the past, to align this SX-99.? The slugs were free and the tool worked. But... the rectangular bit is the correct one, and I can see that the smaller bit could damage the slug as it does not provide total contact with the wall of the slot.? But that I could identify the tool manufacturer... It cam from a MIL avionic shop n the early 60's.? No marking on it.? Attached is a poor photo of the correct and common tool bits. I have not figured how to do very close-up with this camera... yet. ? Jeep K3HVG toggle quoted message Show quoted text On 01/28/2025 8:20 AM EST Paul Lemmon via groups.io <plemmon32@...> wrote: ? ?

Emanuele Girlando All Messages By This Member #31560 Edited Thank you very much to all of you for your suggestions. I preferred option 2: craft the tool my self. ? Paul: I suppose you misread my first statement: it is the last "task" in a project, no the last "project". I don't have so many Hallis waiting to be refurbished, but I am a proud owner of an SX-28 waiting to be treated since ... 20 years! ugh! You said:"Think about using one of your existing tuning tools, cutting off the existing end and reshaping for the needed slugs. ?Be sure to use one which will go into the IF can and which is not needed. " .. and that is exactly what I did. Here is the result: It works! The tip is 2.2mm x 4mm. You also said: "Also if the slug won’t turn apply a small amount of heat from a low heat gun or SMD desoldering heat gun to loosen any old hard wax inside.". It was the case and your suggestion worked very well. ? D. I used the sizes you indicated as a guide to craft the bit. Thank you. My tool is not covering the entire slot length.. the slot length appears to be greater than 4mm. But 4mm is the diameter of the hole you have to insert the tool in, so there is no way to use a blade longer than 4mm. At least it is wide enough (2.2mm) to provide adequate clearance to maintain core integrity under torsional loading. ? Once again: thank you very much to all of you!
