Re: Durable small hex (etc) bits?
The nifty thing about "Ed's Red", the homemade penetrating lubricant/ bore cleaner, is you can leave out the chemicals that don't fit your needs. ATF is the definition of easy on rubbers and plastics,

Re: Durable small hex (etc) bits?
ATF mixed with acetone is bad news for plastic and paint! Acetone will nuke most paints and a lot of plastics. Don't use it to loosen stubborn grub screw in plastic knobs or close to painted surfaces!

Re: BNC Frequency Limit
Yeah, It was. I have examples of 60's style and later OSM and Maury that were made much differently, better center contacts, gold plated, tighter tolerance, etc. More of "metrology" grade style

Re: BNC Frequency Limit
Not sure that the TNC was necessarily 'improved' to get higher bandwidth... it was just used with semi-rigid... copper jacketed... coax. Just keeping all that high frequency... RF goodness... from

Re: Durable small hex (etc) bits?
Somebody mentioned Vessel for JIS tools.? I discovered those guys about 20 years and several employers ago when we needed non-metallic screwdrivers for adjusting inductor cores in ultrasonic

Re: BNC Frequency Limit
Hi Jinxie: When I was working on the HP 4380S 8-port VNA I ran into this problem with with all flexible cables no matter what connector they had. The solution was to build the cables using only solid

Re: Durable small hex (etc) bits?
The liquid can is more cost effective, the spray can is more convenient. At least that has been my experience, and the stuff really works. -bill

Re: BNC Frequency Limit
Agreed. I have a couple of BNC cal kits for my VNA and it is really difficult to maintain good phase stability during the cal process when using BNC connectors. This can even affect measurements down

Re: Durable small hex (etc) bits?
There's only one Kroil, whether you get it in an 8 oz drip can, an aerosol or a 55 gal drum. They make some other products as well, including lubricants, but the penetrating oil is what you need to

Re: Durable small hex (etc) bits?
After reading this I just ordered a Wiha 35392 set too. As for the Kroil penetrating oil, I see there are several different ones. Which one is the best for loosening stubborns knob screws? Great

Re: BNC Frequency Limit
The main problem with BNC is when it comes to anything phase sensitive. A VNA shows this up really well when you wiggle the BNC plug or the cable going into it, the phase response goes haywire and

Re: BNC Frequency Limit
I had some free time today so I dug out my old HP 83752A 20GHz synthesised sweeper and fed it to an Agilent E4440A spectrum analyser via a very expensive Gore cable. The cable is about 30cm long using

Re: Durable small hex (etc) bits?
For screwdrivers and the like, Wiha and Wera are excellent brands, but the one I've got that I feel eclipses even those two is PB Swiss. ?They were what was in my tool kit back in the early 90s when

I¡¯ve had excellent results with both the hex and spline wrench sets from https://bristolwrench.com/. Their products are made in the USA and have been for 111 years. One of my spline screwdriver sets

Re: Durable small hex (etc) bits?
Whoa! JIS (yes it is Japanese Industrial Standard) is not the same thing as Philips! The angles are completely different and they are not interchangeable. Much like Pozidriv and Philips being

Re: Durable small hex (etc) bits?
If you are looking for small precision JIS style cross point screw drivers, aka phillips head, Vessel makes very good sets. I use them on camera lenses since JIS is just enough different from

Re: BNC Frequency Limit
G8VKB beat me to it. The C connector is a high voltage rated connector with no commonality to N or BNC. They have tapered, contacting insulators that provide longer breakdown paths. They were devoped

For Posidrive I have a set of this "lesser name" brand Dave recommended (which is excellent; I find myself using it for just about everything "cross" driving). Can't think of the name. Not to
