Re: First time using super glue chuck

A workmate was using eyedrops to battle an eye infection, went to the refrigerator in the middle of the night and inadvertently put drops of Loctite super glue in his eyes, spent a week in hospital! Have no idea what they used to dissolve the glue? A hard lesson learned that work materials should n...

Re: TIG torch electrode

Nyle - The lincoln manual said that the electrode tip was to be tapered but blunt, but I tried it both ways, as per the manual and hand grinding a rounded tip, I got acceptable arc starts and got to laying down some dimes with a little fiddling of the settings. Being new to all things tig I did dip ...

Re: TIG torch electrode

Bill, My setup is using 100% argon, 15 cfh, the pre flow and post flow about 15 sec is controlled by the welding unit which unfortunately isn't user adjustable. It could be that I had some contamination on the aluminum scraps I'm practicing on, I scrubbed them with dedicated SS wire brush but did no...

TIG torch electrode

I just got started teaching myself TIG welding aluminum with a Lincoln SQ wave 200 and I have some questions about the electrode in the torch. After using the torch for a while the electrode has hard dark gray deposit on it which makes getting the arc started difficult I have to either brush it off ...

Re: Diaphragm fabric

Thanks for that bit of information. I am aware of Kevlar, but was not familiar with the word aramid. Unfortunately, that's likely not a good choice, as the diaphragm must be capable of stretching, and I strongly suspect Kevlar doesn't permit that quality H Glad you found a diaphragm material ( subj...

Re: Diaphragm fabric

McMaster does have sample packs of rubber sheeting, 8450K2, quite spendy for 15 assorted 4x4 or 6x6 sized sheets. The 9402K22 I mentioned I'll guess is reinforced, since the product description says it's a aramid ( kevlar ) /buna-n blend it's probably worth it to ask McMaster for a sample of that pa...

Re: Diaphragm fabric

Harold, have you looked at McMasters offerings for fabric reinforced rubber materials ? I took a brief glance thru their Buna-N and Viton rubber sheets and some of them come close to your .036 thickness ( 9402K22 ) most of what McMaster offers is 1/16" thick. I'm not sure where this cutoff valve is ...

Re: Another "What is it?" post

I kinda agree with reubenT it's a adjustable length holding / clamping thing,
the "bone" shaped flat piece looks like it attaches to a flat surface.
Does the part with the rope knurled knobs extend out ?
Looks like it does.

Re: Rodents like wiring.

The wiring difference is night and day, nicely done !
I believe you when you say that the NT100 wiring took more than 70 hours,
btw who makes the NT100 you did the work on ? Googling returns those little
Nissan vans you see tooling around in Japan.

Re: Rodents like wiring.

The reason the battery had gone dead was there was a short in some part of the rear defroster circuit. After charging it, the short caught the harness on fire. The fire didn't total the car - the repair cost to replace the harness did. It was 70 hours of labor at a cost of $14,000. Steve Holey Gold...

Re: Mill lubes

Hi Wayne, I tend to like Mobil Vacuoline better on vertical surfaces like columns, it has tackifiers so it doesn't drain off vertical surfaces, I use it on my PM 932 vertical column ways. I get it from BRW Technologies, but they no longer have a web commerce site, but they are on eBay now , a pint w...
