638 is only good to 300F. Higher melting point solder? But what do you mean by "floating around while hot"? Whlie machining?

The plate needs to be somewhat wider than the bottom of the T-slot. That makes sure that the overhang of the T-slot is loaded in pure shear rather than as a cantilever.

With just a bit more work you can make it convertible to a drop hammer

Okay! Grade 5 not 8. thanks What does the manufacturer recommend? I use grade 5 on my haybine because that's what Matthews says to use. The bolt clamps two 3/4" plates in a location where a mashed-over grade 2 is *very* hard to remove (Made that mistake. Once.) Grooving does not seem necessary...

The manufacturer of my haybine specifies grade 5 shear bolts to avoid the "mashing over" problem.

That should work. If it binds make the hole bigger.

BTW I learned this the hard way.

You could add a thrust bearing but if you do so you must leave some radial freedom. The axis of the nut will not be exactly in line with the axis of the front bearing, nor wil...

To answer the question, I'd allow about .010" on both diameter and length. You don't want the plate to bear on the bushing and I don't see that the slot-bushing clearance is critical. I like mcostello's idea of replacing the bolt with a stud. You could then thread or press the bushing onto the ...

I built a table to convert my 4x6 to a vertical. The table comes off so that the saw can still be used as a horizontal but it's such a hassle to do so and then reassemble and realign the table that I rarely do it. So now I'm building a power hacksaw.

Interesting. I got a surprise a little over a decade ago when I built something. I took it to Laguna Seca raceway, a Pleasanton CA Good Guys car show and had it on some online forums. People loved it, probably hundreds of photos were taken. For me to build them I figured they would cost me about tw...

It should be free to move as required, so it clamps parallel to the fixed jaw. I've got a 4x6 that I think has that same vi...

I notice that fees have not been paid for the butt-kicking patent. On the other hand, it appears that the high-fiver inventer has actually paid the fees (which amount to quite a lot!).
