Re: Socket head cap screws

Long time ago, I worked with an outfit that did surveying in Texas. Due to legal requirements, some properties had to be measured in Varas, because that's what the Spanish had used for land grants. And of course, now, the vara is defined by a metric measurement. https://www.nist.gov/blogs/taking-mea...

Re: Argent Lumber 3 spot

Update: The experiments with silver solder for joining the steam chest and cylinder are over. I got ahold of some silver solder containing nickel and manganese, BAg-22, same as what the article I had read described. It worked really well on joining (2) 1" x 2" x 1/4" cast iron coupons. I tried it on...

Re: Max point load on 2 x (6)(8)(10) Wood Beam

The thing about tall and skinny - if you consider that the top of the beam is in compression and wants to be longer, and the bottom is in tension and wants to be shorter, the easiest way for the beam to do this is turn sideways, AKA "buckle". I used to know how to figure that. And yes, wood has been...

Re: Max point load on 2 x (6)(8)(10) Wood Beam

OK, I'm still not exactly clear on this - you say: "static frame that would be required to pick up the end of the beam" but you show a beam with a point load dead center. I am not going to vouch for that calculator or your inputs. IF that is what you are designing, the calculator you posted says OK ...

Re: Rod material

Thanks for the education. I have been around people that just call all 1144 "Stressproof". They were evidently wrong.

Re: Rod material

Agree with above. I have some 12L14 I bought, it rusts like crazy. And it is soft. The 1144 (stressproof) would be a very good choice, it also "moves around" very little when machined, as there are lower internal stresses. I made my frames out of hot rolled 1144 P&O (Pickled and oiled) - the P&O get...

Re: Favorite filler for cast iron?

Nickel bearing silver solder (safety silv 50n) does decent on CLEAN cast iron, use the black flux, and don't overheat the flux.

Re: Curious what everyone else does after a swarf filled day

Blow chips out of my hair with some air. Rake out the chip tray with a scrap of wood. Start with a broom and dustpan, or flat shovel if need be.
Try to not track chips in the house, those normal people tend to get upset when they have to pull steel splinters out of their feet. DAMHIKT

Re: Museum of Obsolete Drafting Technology

I had a copy of curve 27. May still have it, not sure. I did a bunch of ink on mylar for the Historic American Buildings Survey. CAD was just coming in, their first ever CAD project was the Texas State Capitol, from 1986 to 89. I was the "straw boss" the last two years. This sheet was done with a Le...

Re: Argent Lumber 3 spot

Dick, I suppose an English wheel would be a good way to do it, but I understand it takes a good bit of practice to use one successfully, my shop is about full, and I don't know anyone that has one. I was tossing around the idea of turning some rolls on the lathe and making a sort of ring roller on s...

Re: Argent Lumber 3 spot

Rudd - I agree that the hatched sections on the drawing look to be cast, with the unhatched sheet metal. This one is 56" diameter or 11.2" at 1/5 scale? Comparing it to the track gauge, the Argent 3 looks to be closer to be around 40 inches? Not sure on diameter. Luckily my office has been doing a ...
