Does anyone here still use those old gasoline blow torches?

I have a few, and use one now and then for melting lead and such.

Robin?
 
I have a brass blowtorch that uses naptha gas in them. Bought it new in 1966 to burn paint off a house that I was hired to paint. Painted that house and got enough money to buy my Pioneer1450, cut enough wood with that saw the first winter I worked it to pay back for the saw and had a couple of grand to boot.
 
Hand filed the chains on one of the 460`s, a 440, 360 PRO, 026, 038 Magnum and the Jonsered 590. These should be enough saws for tomorrow`s cut. Only cutting out the roadway and powerline right of way to get this project started.
 
Get to cut wood myself tomorrow. Have to cut some cookies and a few stands for my step sons wedding in 3 weeks. Going to use one big one to sit the cake on, for the centerpieces to sit on and for coasters. He's a little red necky. LOL. Couple of posts for flower stands and such.

Looking forward to letting the 365 eat. Might try to put the fuel line in the Super XL 12 tonight to see if I can run it tomorrow. Get a filter from the local guy on the way to the site. I would be extremely pumped if I could get that to run with a carb kit. Not afraid of putting the kit in but just want to run it and see how much grunt it's got.

The XL 12 is no powerhouse but its a 54 cc engine and cuts really well for the old saws they are.
 
Heat sinks are usually made of aluminum. Cheap and light.

Silver is the best. Copper next.

Heat sheilds don't have to suck heat.

Some heat shields are aluminum. Again, cheap light and easy to form and don't hold much heat. Not enough mass.

Heat shields work with heat thru radiation.

Radiation by temp, not nuclear. Lol

Most any heat shield at those temps will reflect about 90% of the energy.

You put 2 of them in series with a 2000 deg F source and you can hold your hand 1" away.

As long as the sheilds dont transmit heat well.

Convection is the next class down. Below about 1300 maybe, it's been a lot of years.

But you need air movement to transmit heat well.

Think convection oven. Wonderful for baking. Better transmission of heat.

Without air movement. Crappy heat transfer.

In tests men have sat in an enclosure while cookies baked with no lasting effects.

Cookies didn't get done. Lol

You can reach into a 500 degree oven.

Just not a convection oven.

Conduction is for lowest temps. Got to touch.

Cookies burn on The bottom. Near that aluminum heat sink. Where they touch.

My $.02 from building heat treat and tempering furnaces.

Vacuum and convection.

Hey all
 
Gotta go cause minor localized flooding shortly

Tomorrow is the first day of archery!

Yay!

Chase fuzzy deer!

Hey all


May have figured out where you work. LOL Based on that.
 
Alright out the gohrage I go. Time for a little saw R&R. Few more little pats and I can have 3 or so going. No time to tinker this past week. Have to sell a few things to to have some mo pats $$. Hope to finish the 350 and 45 this upcoming week to make room for a lunker 064.
