This Clinic has been a wonderful thread, many thanks Kathleen. And to Pal, for the above pictures. You've all got me ready to try the J-bar replacement routine. Haven't done that yet, although have had success with other parts of the job, including deep bite marks on a black J, which I filled with layers of slow cyanoacrylate. Would be pleased to discuss further if anyone wants.
1) what are the correct j-bar length references? where should the base land, and how far in does the crook go?
2) what did you use for the spacer and is one necessary? Is it just for measuring the bar insertion?
Tim, I am learning as I go, sometimes by trial and error, not always the best way. While repairing a Transitional FPN member eni
shared a measurement of a j bar. Look here, http://www.fountainp..._1#entry1752963
I know I have shortened up j bars for SJs and just pushed them into the barrel, figured how much to take from them to have the section clear of it when reinserted,taking it in and out, not always easy, not desirable. I too, would like to know specific measurements. The last J I fiddled with I had to reconfigure the crook to shorten up the bar, preferring not to mess with the upper end where the 2 piece J bar was joined. Messing with the degree of curve in the crook I have to be careful that the j bar has the full degree of spring it requires to return to a position high under the lever after being depressed. I fidget and fidget, in and out until it seems just right.
Concerning your question on spacers,the spacers appear to be small hard pieces of rubber. When they are present I leave them always checking that they are vertical before inserting the j bar. These spacers appear to be about 1/8" in length. I am guessing one might be made of an eraser. I have a Pentel mechanical pencil and its replacement eraser could easily be cut to size and about the same diameter as what I see inside my Esties.
I am happy to share my restoring successes, though I have been learning as I go and really appreciate when the more experienced experts come along and answer questions. So, I join you in asking, just how long should a J bar be for a J, LJ and an SJ?
Schools in my town are closed for another snow day, so far we have 6 days to make up in June, summer is getting shorter in KY. To enjoy my unexpected day off, I just may turn my attention to one of those last three pens awaiting TLC in my clinic.
Over the weekend I purchased two more Esties from ebay, both unrestored, one with my favorite 9668 nib. I hope when they arrive they only need new sacs. I said I was going to refrain from admitting more patients for awhile but I just can't help myself. Look at my quote.
