Refurb EFM 700

One question I do have:

Since putting in the buck, I notice that I do hear a slight bit more grinding with the worm. With the rice, it was nearly silent ... could not even tell if coal was moving most of the time over the sound of the blower. But with the buck, I do hear occasional pops ... or a slight grind ... not always consistent ... but now and then. The work shudders very slightly ... just noticable .... not sure if the auger is too long sticking out the tube where it feeds in coal ... or just my paranoid pickyness that I notice a difference between the rice and buck. I did not measure the length sticking out .. but thought it was maybe 3 inches. I could let it get low and measure it .. but if it is ... well, I guess I have to get it cut. But maybe I'm just over thinking it. I just don't wanna damage my new toy ..

Buck will make more noise in the auger. 2.5-3 flights (not inches) of auger past the end of the pipe is good. Check it the next time you have it shutdown. If it is running good and you don't hear a lot of crunching by the end of the pipe, it should be fine.

I would leave the chimney cap off. You should check the draft with a draft gauge. Your old oil man should have one...tell him after all those service calls he owes you a freebie. Ha

Haha ... you are right!

Ok my friend ... thank you for the info. I'll keep an eye on her (can't help myself really ... she's a thing of beauty)

Sounds like you have begun "The Affair" with the lady downstairs. When you move the bed down beside her, we will all know you have 'gone over' to the 'Carbon side'. I bet you are kicking yourself for waiting so long. Enjoy, just go easy on her!

Ok .. let the barrel get empty to the point I could count the number of threads on the auger. I can count 4 sticking out of the tube but the one is usually pretty close to the tube .. which means what .... 3.5 flights? Flights go by the actual spaces between the auger threads or the actual threads? .... the fourth is pretty close ... maybe 1/2 to 1 inch away from the tube at the most when there is 4 out... of course ... position varies depending on the turned position ...

Do I need to get a longer tube? These guys that refurbed it ... they did measurements on the original .. but it is possible that the length varies depending on coal size I guess .... it is also possible I suppose that the 700 can handle buck with a 4 thread position ... but I have no idea. Is there a way someone can find out for me? I thought we were burning buck .. but when I reached down ... there was still a lot of rice near the thread .. so it is burning a mix right now ... I just loaded up the bin with buck .. so I really kind of want to know. Don't want to hurt my baby ... haha.

My auger sticking out of the pipe in my barrel looks about the same as this one:
