Mini mill issues

[ginger_badger]

Hi guys, right... Been running out oak and pine into beams with my mini mill, all come out great until today, can any1 shed some light on how do you ensure the saw bar cuts straight?? Hasn't been a problem until today, managed to cut odd shaped beams, the nose seems to be cutting 2 deep into the timber leaving me with 13" tops and 10" bottoms!!! Not a happy bunny, tried to re setup the saw in the clamp and it looked like it was going to cut flat but alas same has happened, any1 had the same issues?

Could it be tooth wear?

Put brand new skip tooth on it so don't think so, I have the timber sat up on logs off the ground 2 so, I'll have to double check everything again 2morra :-(

Do you mean that the bar is bending in the wood i.e. you exit the cut and the bar pings back straight? Almost like it was under pressure?

 

 

I had this particularly with the new flip and rip and I think it has something to do with the saw bar not exactly parallel to the rail... it may be angled in or angled out slightly...

 

 

Sorry I can be more specific but not home and have not got access to any pics...

 

 

Can you take some pics of your set up and the process of what's happening?

I can try uploading pics via the app but currently haven't got a pc, the best way for me to describe it is. I'm managing to cut beams that are 13" on the top face of the wood but the bottom face is more like 11, as if the bar is cutting deeper into the wood at the nose end than the end in the clamp, does that make sence lol??

is it the same all the way down the cut

You are using guide rails?

Yep I'm pretty sure I know what you mean, the nose is bending in...

 

 

I've had that with longer bars... what size bar are you using? What stage is the bar at - new, not used much, used a lot, not got a fleck of paint left on it?

Seems to start off ok then walks out, the bars 24" husky not had that much use really and the only rails I'm using are the rails that the mini mill runs on are there others ? I'm not back up at my yard till Monday now but I'll take some pics of the beams, may reset the running rails also

what size timber have you got the mini mill rails fitted to and have they been on it for a while
