Yeah, blow the warm air down.

'72 K5 - Greg's @MightAsWellK5 Build
- Thread starter Greg72
- Start date
This is the build description. I will improve this later. (GB)
I stretched a plastic sheet across the large opening above the K5 to help contain the warm air a little better, and put a box fan near the top of the staircase to help push the air back down.... It's better but on really cold days I'm just losing too much warm air through the old, non-insulated and leaky roll up doors.
I tried insulating the attic rafters a several years ago with some 10" or 12" thick Fiberglas bats (R-39?) and then covered them with a thick plastic. It ended up trapping moisture and ruining the backing paper. It's a complex issue to solve. The temperature differential between the outer air and the inner air temps (and dew points) creates condensation that can't escape.
I think the ultimate solution will be some closed-cell spray foam (and lots of it!) to replace all that Fiberglas insulation.... And certainly some better garage doors too. The lingering problem is dealing with the lousy air quality when I'm grinding / welding with everything closed up tight. I think a ghetto solution might be to zip tie a furnace filter to the back of my box fans so that the debris gets trapped instead of staying airborne and blowing around everywhere?

Does one arbor fit all the cutters? I was using hole saws the other day to make holes and even slugs (with the center bit removed) and the edge results were pretty poor, even clamped in a drill press. I didn't know those cutters were so affordabe. Or maybe they aren't because the rest is missing?
There is one arbor for all sizes from maybe 1-1/4" up, and another for anything smaller.... The arbor has a L-hand thread on the locknut and a keyway to keep the bit from spinning. You can see the keyway cutout in the image I posted.
I'm at a loss to remember where I got my first set of these.... Vansant maybe?
I'd actually like to buy a few more arbors just so that I don't have to spend time swapping cutters each time I want to drill a new hole size.
The center drill bit (pilot) is also replaceable. Mine's getting a bit dull... so I'll probably seek those out as well. If you have any luck finding the source for ALL the Jancy stuff please post it up here.

Found it!

You can buy them individually or in kits. Not cheap, but not impossibly expensive either.

Since these plates are only 1/8" thick material I was able to just stick them in my vise and hit them with a deadblow hammer to get the first angle...
...then it seemed to work well to weld the sections leading up to the final bend so that the metal was nice and hot where I needed to bend it again. A few more hammerblows and the last section would lay down really nice and flat.
If you ever need to do something a bit heavier, your shop press makes for a nice brake with a short piece of angle iron backed up with a piece of solid round. These were 1/4" x 1 1/2" and bent like butter and you can put a protractor on it and bend to a set angle more accurately than whacking it.
That 1" - 2" looks pretty useful, bookmarked
I've seen the tricktools place before when looking for bender stands(ended up making my own) but haven't ordered from them yet.I was going to say the same thing, except standing the arbor plate on edge is a little dangerous. If you you want to bend something wider these work quite well...

I ended up buying this one because it was the perfect width for my press and I got it on sale...

It bent 3/8" x 2" with only 7 tons of force, and I bent 1/4" x 6" with ease as well, I am sure it is capable of much more, could probably bend 1/8" the entire width no problem.
I was going to either build or buy one but for the few bends I needed I didn't want to pay for it. I did match grind both plates together so at least I had 2" of surface. They were stable even without clamping them together which would have been my next option should they have shown that they wanted to move.
For your purpose it looked like it worked quite well actually. I just wouldn't advise others to do that, as you know, if things aren't perfectly straight someone could get seriously injured with projectile metal parts.
Yeah seriously.....
That thing could break, bounce off something and hit my flip flop covered toes in the summertime.
Craig just ordered these

I know nothing about them. Seemed decent for new

Post up a review once you've played with them a bit...
Almost everything in my budget was 6000lb. (1500/pad).... I searched a long time for ANY manufacturer who made something with just a touch more capacity...but the prices went up exponentially.
Does that set have a CG capability? I saw that on the Intercomps and wondered if it might be a cool feature to play around with?

I have no idea, have done no looking. When he told me he ordered a set of scales I was like oh snap how many thousands was that???
Then he sent the link, and for 10k lbs, not bad imo for the price.
Will have to report back once he gets it.
That is a good price for 10k scales.
Come on Greg, you're not letting a little bad weather stop you from progress are you?
-14F this morning buddy..... I had to put on long pants today!
3ft of snow in the last week, another 12" - 18" due tonight.
All I feel like doing these days is sipping whiskey, and watching TV.

We had an inch of rain yesterday. Might be the only inch we get all year.
I was sweating today in my shorts and t-shirt as it dropped to a brrrr-freezy 62* (that's with the wind chill figured in
from, you know, 62.5* 
)-- A

OOh That's -26c or so! Yeah that sucks! Whisky and TV sounds like the way to go for sure!
Not much fun shoveling snow it that!
