Exhaust expander?

So now that Justy has a motor (haven't fired it up yet...) I feel real exhaust is in order. What remains of our 1.75" thing I built years ago is pretty limited and pretty smashed up, also lost the actual muffler at Pines the last time we ran some part of 2 stages...

So...
Thinking slip joints would be nicer then welding on flanges.

Does this thing work, or am I wasting time and $20 trying to make my own joints?

Waste of money. A good manual expander is expensive.

As for welding flanges, no try the nice overlapping tabs seen a bit down in this thread:

Cheap and simple and work even when bent and bashed.

as for the bump up, find a good exhaust shop and take the parts needing a bump in and have them do a LONG bump..nice piccies in that thread

Waste of money. The metal will crack in half. Just go to a local exhaust shop and they will do it for you. Will only cost you a couple bucks.

yep, read the thread too, that was the inspiration!

called the shop I'm getting the stuff from, $2 per... wouldnt even think of any other way...

Yep only good to straighten out very slightly bent bell mouths....and even then it will break. I wonder how many of these have been sold over the years.....

Aargh, I hate those things. If they weren't made of cast it might be tolerable for fixing old pipe, but even that breaks the damned things. My real live exhaust machine exerts a lot of pressure to expand a pipe. I usually do them gubmint projects for nothing for the local people. It takes a minute and is cheaper good will than wasting money on advertising.

Huh.. I have something like that tool that I picked up at an auto parts store years ago. Its worked very good for taking the dimples out of pipe from clamps. I think I've also used it a time or two to make a slip joint. Maybe the HF one is just extra crappy.

I do tend to use the electric impact on it FWIW.

This isn't floor mat anarchy

I think the point is they work okay for removing clamp dimples, but I was hoping to make slip joints with it (expand the whole pipe), and it just is not the tool for that.

Not the HF one, anyway. There used to be a quality one of these made by some USA company, but I think it is LONG GONE. Because everybody bought the HF/JC Wimpey POS.....
