I was looking into a stress reliever to have at work and I decided to make some surface plates by lapping. I was going to go for a 3 plate method by using iron, or mild steel, plates
What compound should I start with for lapping cast iron? Would valve lapping compound be the right place to start, or would I need a more abrasive compound? I'm hoping to have a rough starting figure on grit. I see everything from 80-1200. Is there a cheap but works compound?
Check McMaster carr for lapping compounds. The clover stuff is reasonably priced. The choices they offer gives you an idea of the surface finish you might be looking for.

glad i saw it at an imax. pretty good, but not as good as the first.
best scene was first appearance of whiplash at the race.
Well, my iron has finally died. So, I'm wondering what one you guys suggest. I'd like it to have enough oomph to assemble battery packs and and connectors.
Does anyone have any experience with the Hakko clone soldering irons? I need a new small soldering iron and would love to buy an older Hakko but they don't seem to be available here. I always wanted one when I was younger.
And the reviews of the...

Hey Dave,
Looks like the hot air rework adds another dimension to electronics repair. The consensus seems to be they are reliable which is a good thing.
Marc, I enjoyed reading your opinions and experiences with that iron. I was thinking of...
I have a Weller 60 watt. Of course that's a joke pen iron. It got me to purchase the Weller 140/100 watt gun version. I use rosin, I preheat...Well this gun falls short soldering 8ga stranded wire and just now let me down trying to connect a 4mm...

At my work they send you to class to become NASA certified to solder connections for space flight and we only use soldering irons. At home I have an adjustable weller that I use for smaller gauge wires but for the 8 and 10 gauge wire I use a fixed...
Scored a couple big bear projects lately and after thinking about it for a while I decided to create a chassis for one of em. Nothing crazy, with the very limited suspension I didn’t even bother accommodating oil shocks. Battery can fit sideways or...

I haven’t really shown pics of it because there are a few copycats around lol
Am I missing something or is this thing a piece of crap? :evil: Like a sucker I bought one several years ago thinking it would be good for r/c. I quickly found that the cold part of the Coldheat name was more accurate. I kept it thinking it would be...

I use a butane soldering iron. It took me a long time to acctually get one, as all the butane tools I've had in the past sucked pretty hard. Now that I have, I don't see myself going back any time soon. I use a blue point which is the same as the...
Got a wide chassis 7+5 :shock: that I can't seem to figure out. Is this a non-associated chassis? Looked at all the manuals and don't see one in this config. Also got a narrow 6+4 that I think is a 10lss just wanted to verify.
I decided to cracked open my B2-B3 conversion kit but after some heavy breathing and humming and hawing, I decided to leave my B2 alone and not convert it.
So now I've been considering to build up a RC10 B3 from the RC10B2-B3 conversion kit -...

It will be a runner, I am just waiting for the last part - a battery strap of all things. I could only find the Thundertiger version and it has had to come all the way from Australia.
