Hello everyone!
I live in Ukraine and recently purchased excalibur ex-21. Unfortunately there are very few people who own this saw here and sadly even if they are out there somewhere i don't know them to ask some advises, so i went here to ask your help guys

So, i do something wrong with it. First problem occured with it - the the nut on the screw which holds the lower rod under the saw table went through this rod (!) and didn't hold it anymore, so i got a beating noise and was wondering what is going on. Found it and fixed it with the washer but couldn't screw it down till the end, so it left kind of untight.
Then, i try to scroll the 38 mm pine - it's very very slow, very hard to scroll - i don't think it should be like this! OK, it's 38 mm, but it's pine after all! I use flying dutchman ultra reverse blades, tried all - 3,5,7,9. From time to time it's ok, other times it piece start to wobble, just today i tried to make a U-shaped turn - the saw itself started to make growing buzz

Yes, i've read about tension, i've read that i shouldn't push to hard, 'saw will do it itself, blade will just go with the grain direction' (!) this makes me want to cry

i don't have that at all
Also toady i discovered that my blades goes back and forth in arm's plane, i mean, horizontally. So it doesn't go strictly vertical with every stroke.
I hope you understood my messy story, english naturally is not my native language

very big thank for any help
