Hello how are you today. I have the same problem and i found out that the stove is starving for air. Have you noticed that if you close you draft a little the thumping stops. I was told to open my shop door a little and this should stop this. I have not tried this out bacuse i was just told this the other day…but it is worth a try…let me know and i will do the same the next time i am in the shop.
Till then take care and good luck

Last year when pipe was new, both insulated through the roof and bare black stove pipe, it sounded like a steam locomotive. It belched smoke each time. After every thing heated up and i got a good bed of coals, it would stop. This year, with minimal use, it hasn't happened. Beats the outta me, maybe it's down draft, pipe length, or maybe just needed to burn off residue in the pipe.
Almost the same setup Ryan. Back vent, 6 ft of black pipe, to insulated thimble with about 7 ft of insul. pipe. No problem with maybe 2 weeks of burn this season. With wind, cold rain etc. Pipe was new, stove is old. ?

Does it only do it when the pipe is cold? Sometimes you have to sort of preheat them.
I've been thinking about putting a woodstove in my shop-does it work out well for you guys? How long does it take to warm things up on a really cold day? It's in a 1880's barn with wood floor, kind of worried about burning up a great building. Any thoughts?

Understand the warm pipe thing, and it had to get pretty warm! This year it needs to get warm but only the normal start burn. Maybe we've got to throw barometric pressure into the mix. Outside of the pipe being 1 yr older, there's no noticable diff.
Wood stove in a shop is the ticket. Safety should be an issue but being safe is not that hard. Have had old pot bellies to the more efficient fisher type. Warm up the soup or leftover ribs. Gets bearable in an hour for a 28 x 28 x 10. With good insulation and some heat sink around it, it'll retain at least a semblance of warmth the next day. You'll burn the scraps pretty quickly, so some wood will be needed. If you do alot of work in the shop, maybe think another kind of heat. If you're talkin every so often, then I'd sure consider it. Use your propane job heater for that quick boost.
*Thanks all.It's not a make up air problem because the shop is old and leaks like a sieve.The pipe is not only hot, The stove draws so hard (sometimes) that water will sizzle at the chimney thimble. If I look into the stove, there is a vortex of flame going right into the lower part of the chimney. I would like to keep some of this heat in the shop."Thumping" is a good word for what I've got. The smoke seems to thump out.MD: If you're got a shop of any size, I don't think a wood stove would do what you want. Of course I don't know where you are. It's in the 20's here this week and I can't keep the shop warm enough to be comfortable without a coat.Fuel is cheap though, I just burn scrap lumber.

The main part of the shop is a very large space but for
winter, I mainly want to heat a smaller room that is
partially insulated, it's about 15x32 with 11-12 foot
ceiling height.
-10F here last night for the eclipse.
Thanks for the advice.

-15 for a high today...when I sat in the truck this morning the vinyl seat didn't give...I would guess -30, welcome to Canada.
Finally got my wood stove working in the shop. My father in law hooked up an oil burner with a wood stove...same chimney, so I can warm the chimney with the oil burner and then keep the temp with the wood. I have found cedar sawdust works well in those shopping bags...smoulders all night. I did however have to remove 18' of bird nests from the old chimney before it would work. I spent the day before last on the roof 50' in the air, (frost bit my ear), trying to clear it. It used to be an orange lodge (like a church), and hasn't had heat in nearly 30 years.
I don't quite have a solution to your problem aside from blocking some of the wind running across the opening of your pipe. Maybe give it a cap and block one of the 4 sides, preferably the one into the wind...
I would also caution you to protect against sawdust, and flash properly...if you have a tinsmith friend he would probably have some creative ways of keeping your wooden structure from igniting. I'm running almost 30' of pipe to the chimney and upstairs, (in the milling area), the pipe is encased in a square duct, (removable to clean). The duct merely gets warm, but has a hole near the top for heat to escape.
Good luck gents!

*How far does the chimney extend above the ridge? Does this only happen when the wind is blowing? It may be that if the chimney is not tall enough, air might be trying to go down the chimney. Just a thought.
*The chimney is about 20' from the ridge and is at about the same height. It's on an outside gable wall. I think Lawrence is onto something.The wind here is unbelievable. It snowed a couple of inches yesterday, not much at all. Right now, I'm looking out my office window and I can't see the next telephone pole along the road from all the blowing snow. I've got 4 drifts in my yard. I think I'll try some sort of shield on one side of the chimney. I can't make it any worse.I'll try to keep my ears warm though.
*If the cap and doesn't help, try raising the height of the chimney. I think Lawrance and I have the same thoughts as to the cause. Next time you start the stove, get it to smoke some, and go outside and check the chimney. The smoke coming out of the chimney might be of helpas to what's happening. Stay warm ......up in Maine here, colder than ___________ (you fill in the blank).

I've got a wood stove to warm my shop. The stovepipe leave the stove at the rear, goes up about 5 feet and into a chimney. the chimney is probably another 7 or eight feet above the thimble.
I live up on a hill with no windbreaks for almost a mile in all directions. It's windy here!
Everytime I use my stove, smoke blows into the shop for a couple of seconds and then it draws so hard I have to keep my tools chained down so they don't get sucked up the chimney. A few seconds later, it's blowing smoke into the shop again.
I've got the damper closed down as far as I can without it smoking all the time.
What am I supposed to do about this?
