who makes the best strongest rubber oil line automotive hose? Best clamps?

I have an automotive application. OEM "rubber" hose on this engine often fail. After several years the manufacturer replaced it with solid line. Earlier year owners often swap out the rubber for the later year solid. This is too involved for me right now, so i was just going to get the best high...

felt paper has been tested and it is not a sufficient barrier. maybe they should have asked Ron instead. I just pulled the treated wood, it's too risky.

Im installing a galvalume metal panel roof. Supplied steel screws are used to hold the panel clips to the roof wood deck. Some of the wood is rotten and/or termite damaged. So, we have been replacing that with treated wood. I just heard that galvalume is NOT compatible with treated wood. Several...

that is what collar ties are for.

Im not sure if im in the right forum. maybe should be Building engineering Forum. Im planning on installing rafter ties in my 1952 cinder block home. It has no rafter ties at all. Every time Im in the attic and look around, I wonder what holds up my roof. The ceiling joists run parallel to the...

I remember in electronics school in the 1980s we learned that the best way to damage a very old piece of electronic equipment was to power it on with full voltage. After a long time with no power caps go to zero ufd, which will pass the full voltage and burn out other components. Something...

that helps, thanks. ref: There is horizontal support at the ridge. So you can calculate all that you need to know.

huh? ref: Do a free body diagram of one rafter (there is no vertical support at the ridge)

I cant understand this math. ive been over and over it. Each time I get a little further, then I loose it again. ref: How to calculate rafter thrust? -Help! at http://www.eng-tips.com/viewthread.cfm?qid=105386 Can someone help me figure cable load? 4/12 24" rafter spacing. No rafter ties...

I understand. Thank you.

I need to secure these rafters to the cinderblock top plate. They are just toe nailed in now. I want something stronger that i can screw in w/o removing the planking. Any ideas? I might install rafter ties, but Im looking for alternatives. pics...

tks

no caps, unless they are inside the mtr.

Ive seen that info. Mine is two speed 115VAC. I can most likely take it apart and figure out the wiring, but both windings use 115 or a lower voltage was used for the lower rpm. I dont have a variable AC power source. Anyway, just hoping someone around here knows something about Sole mtrs or...

so, its an anchor? There are too many wires coming out of it for me to experiment.
