I can't figure out why our CAD guy always insists on drawing parts with speed holes in them :mad0260:

Goddammit. Now I'm grumpy too. :bs:

:clap: lol

I don't think he understands that more features is more processing time= moar expensive.

Do I need to go down there and beat him with a Machinery's Handbook? I'll do it.

He's pocketing the chad and taking it down to the copper and cat converter exchange.

It would be more to the point to beat him with a book titled "Common Sense."

i'll take a copy of that when you're done with it.

heck, before i use it, i could probably use a refresher

Ugh, furnace quit at my house. Renter called me earlier. HVAC guy said needs an exchanger at 3200 and a flame rollout switch. May have found an exchanger for $1k online but I want to inspect the unit myself since I am thinking about just replacing the unit. I owe a bunch in taxes this year so if I can write it off might as well make Uncle Sam pay for some of it. Tenant says he can weld it lol

Aren't most exchangers cast?

That'll weld like a knife in jello

He’s …….. he means well.

You most certainly can weld cast iron. It is slow and won't look pretty but will be completely fine. If I still had my 58 Ford sitting here I could have shown you a very nice welded cast iron exhaust manifold. I have done it at least 4 times way back in the olden days.

i believe most are cast aluminum, and thinly cast at that

It’s aluminum.

OHHHH that could be different. I doubt I would even try that although it is probably doable.
