    Default Silex no66 marking gage

    Does anyone have a Silex No 66 dual marking gage.

    I am trying to figure out what holds the front marker, and how the 2nd is held stationary when it use.

    Hi Richard, Guys,

    Looks quite crude ! I would think that the scribes are just pressed into place.

    I made one some time ago and find it quite useful for some jobs. Though laziness often means I just use the digital vernier to scribe a line.

    The scriber is a 3 mm broken carbide PCB drill. Un sharpened at the time this picture was taken.
    I used a screw in the end to clamp the scriber.

    Not much help, but it looks like the outer is held with the thumb screw and the inner is adjusted via screw and locking nut. I suspect the scribers are a push fit into the split ends.

    it has always had one scribe but is obviously made for two as the pic the Michael has posted. Its just that I cant fathom why the first scribe only goes thru a hole at the tip while under it passes tbru the slot. ...and what stops the slide from moving once its set as the adjusting mech at the end pulls off. Wonder if its meant to be a tight but removable fit?. ???.

    If I cant figure it out I will just return it to a single marking gage.

    Yeah i s aw that also Michael it doesnt tell me why the 1st scribe goes into a hole in the top of outer arm but passes thru the slot in the bottom? Would have thought it should have a support at bottom as well. The scribe in slide is also a tight fit ie removable for sharpening/replacement etc.

    Hi Richard, Guys,

    Could it be that the back of the scriber runs in the groove so that both scriber’s are kept in line for marking two parallel lines.

    When you mentioned "Tin Smith" it occurred to me that marking a parallel line is what you would do for a fold.

    Not sure I understand the question that you are asking. Attached is a sketch of how I think something like this should be arranged (the threaded part of the inner slide may be separate from the scribing part...). The inner can be moved and locked in postion with respect to the outer, and the outer scriber can be moved with respect to the external stop.

    Based on your photos, it looks like you have most of the parts - although I'm not sure that all of the parts are original or are not without damage.

    Only part it is missing is one scribe.


    Maybe these pics spell it out a bit better?

    as for the thngymebob at the and..on mine it pulls off...I am guessing mine is a tad worn in that rea and is cause of it coming off easily

    The thngymebob at the end should be fixed on the outer tube. That is how the inner and outer maintain fixed relative positioning. A bit of bearing locker would do it if the push fit is a bit ropey.

    Seeing the slots I think that gauge has been mis-treated sometime in the past - perhaps someone trying to get it apart or trying to get some extra range out of it. The hole in the outer should be 'whole'. Should the end be plugged to provide a hole for the scriber? Can't tell if there is a plug there already but there looks to be a groove around the top that suggests something in the end of the outer may have been secured with a crush fit. Alternately (or maybe as well) a dot of weld to close off the hole may be needed. If you haven't got a TIG I could manage that for you if you want to drop around.

    Hi Eskimo,
    I have a Silex No.90

    It also is a dual.The scriber pins are indeed a friction fit.Mine has twin knurled head screws - one for each shaft.
    The shafts each have a flat for the screws and both run about 7.80 mm diameter and the split is .94mm wide.

    Engraved markings are in imperial. The registration face is recessed for both shaft scriber pins to recess into it.

    Have you checked the shaft diameters each way. Possibly the shaft locks with a cam action.

    hope it helps

    Hi Eskimo.

    I have a No.66 bought new years ago. As far as I know the No 66 was only ever supplied with a single scriber. I have often been wrong before though,
    as my wife frequently tells me. Mine has a single solid 5/16" diameter six inches long scriber arm with a flat for the clamp screw to bear on. At 90 degrees from the flat there is an adjustment scale with 1/16" divisions. The scriber point is inset 1/16" from the end. I wonder if your No. 66 has been modified to take the dual scriber assembly from another gauge - possibly from a Silex No. 98 or similar?

    Michael's photo shows a No. 98 with the dual coaxial scribers. The boss on my No. 66 casting for the scriber hole has an O/D of 3/4 " . The No. 98 gauge in Michael's photo appears to be larger then the 66 overall, and the outside scriber arm appears to be well over 5/16" diameter, which wouldn't leave much meat in the boss on the No. 66 casting if it was bored to suit......Interesting.

    FWIW I made a separate arm for mine which carries a pencil instead of the scriber point. This sees much more use than the scriber point.

    Frank.

    Hi Frank
    Micheals pic shows the same as mine as it has the adjuster at the end which slides the internal shaft inside the outer.


    Had a closer look at mine and it has two no's...No60ty something on the right....the last digit appears to be iether 6 or possibly 8 partially obscured by a a tinsmiths rivet...why Dad?...why does it have four rivets

    The left side has No98. So I give up...how can it have 2 model numbers.?
