This one looks like the one Stein sells. Stein says that this one is for standard d-sub pins and can not be used for high density pins. However, B&C has one that looks somewhat similar that they say can be used for either pin, with some adjustment. So the question is does B&C have a better crimper that can do both crimps well, or are they blowing smoke? Can the crimper that Stein sells be adjusted to do an acceptable crimp on a high density pin? The crimper I have seems to do an acceptable job of crimping standard d-sub pins, but I am expecting to need to also crimp some high density pins, and would like to use my cheap tool, but not at the expense inferior crimps. If someone has experience with both of these please share your conclusions. Roger The $low$ 4-quadrant crimp tool first offered by B&C and Steinair is the Eclipse Tool Co. product that I introduced to OBAM aviation about 12 years ago. At that time I found that the pin positioners for the 20 standard density pins was drilled too deep and the crimps were placed too far back on the wire grip barrel. http://tinyurl.com/knhjt44 I published a 'modification' that was accmoplished on every tool that I sold and B&C adopted the practice when I sold the business to them. In times since, the Eclipse tool with the stock positioner seems to be okay. Check the crimp position on your existing 20AWG pin. http://tinyurl.com/mk3krvp if the crimps are too far back on the barrel, chuck the positioner in a drill motor, spin it and use a file to cut down the shoulder indicated here. http://tinyurl.com/klojj67 For a time, I sold a 22HD pin positioner with a smaller and shallower pin pocket for this tool. B&C never asked to offer it . . . I think they sell a Paladin tool now. However, Steinair has been ordering quantities of the 22HD positioner . . . Emacs! Which I manufacture for them in my shop. In fact, they have a few dozen on order right now . . . need to go make some chips on the lathe! If you want a 22HD positioner for the Eclipse tool, check with Steinair . . . they'll have more in stock the first wk of Jan. Bob . . .

    Subject: Mystery electronic box
    Can anyone identify the box in the two accompanying photos? There are four relays, more than a dozen silicon diodes, and a power resistor. I can hazard a guess or two but would like to hear from someone who recognizes the box and knows what it is. My neighbor cut it out of a Speed Canard he's rebuilding. The operative words are "cut out"; I do not know to what it was connected. -- Joe Independence, OR

There are commercial products that allow 2 sets of trim switches, and can give '1st push' priority for control, or pilot-priority for control. Charlie

    It's a 2-channel relay deck. One pair is used for (pitch?) trim (labeled on wire). The second may be for speed brakes or nose gear... not sure. The power resistor may be used to limit stall current (landing gear) or the speed of the trim motor. This is a guess, but the wiring shows one wire set as 'trim'.

I think you're all correct. A relay deck/trim controller makes sense especially in light of the Speed Canard having electric trim switches on both sticks. Good job -- apparently this was easy (for everyone except me :-) Alas, there is no prize but I will have the satisfaction of telling my neighbor he needs to repair the cut wires and re-install it <g>. Thank you all. -- Joe
