Logosol B751 Trailer Package

[trigger_andy]

So, I finally have some pictures of the new Logosol Specific Trailer. Its build by a German Trailer Company (dont have a name yet) and supposedly made to meet the stringent German regs to be road legal. It will need approved in the UK though and that would be up to me to have done. Its not much to look at really. Seems really over priced at £2600 plus Vat and £300 plus vat for delivery. Thats £3500 for a very basic looking trailer.

 

On another note my B751 has been cutting 'wavey' its been doing my head in. Ive gone through every and all setting on the mill to ensure the adjustments where spot on. They where all a little off but maybe thats just from it settling in? But they are all good now, even used my verniers where I could. Every single measurement within 1mm. New blades as well.Yet Im still getting a wavey cut. Its hard to see by eye, expecially at the full 600mm wide cuts but you feel it easily with your hand. When you start to dimension it down its very apparent. So Im at a loss what to do next. Apart from buy the Trailer package so I know 100% its not the Hardcore/Sleepers its resting on, plus Logosol could not argue that either.

Waviness down to how it is fed / pushed through the log? Excess pressure causing blade to twist slightly causing the downward cut, relieving of pressure allowing blade to rise again, hence your waviness? Incorrect guide / blade tension? ?‍♂️

Thanks for the tips, any and all are most welcome. Even the daft as it could be something really silly Im doing.

 

Im not putting much pressure on the Saw as I wanted to see if that was causing the issue as well. You can hear from the engine when you push to hard as well, I just let it kinda glide through. 

 

Checked, rechecked, triple and quadruple checked the tension, Blade Guides, Wheels for squareness, blade level against the bunks, bunks level, bunks square. Im really at a loss now.

We have a band saw at work, all be it a metal one but principal is the same. It started to cut skewwiff one day..... typical idleness, no one reported it and i came to use it one day and noticed cutting fluid running out the bottom/back of the casing???? I took the covers off and found a huge amount of shite and swarf in there and could see uneven wear marks on the guides/rollers... got me scratching the old swede for a bit. Anyhow, cleaned everything out and reset everything, pressed go and watched the blades path at each point/turn/guide/roller etc. I could see i running out on occasion and noticed a kink in the blade. That made me inspect the blade more closely, i then found some excessive wear in a few places on the blade, so......
My thinking was, shite build up causing drag/misalignment, kink in the blade possibly causing a tight passage during cutting and misalignment again at certain points. And a dull blade at different points causing excess pressure needed to make the cut added to the above.... a curve cut???!!! So sod it was my conclusion, fit a new blade, cured! [emoji106]
You changed your blade recently?? [emoji23][emoji23]

Yes, two different brand new blades.

Guess the trailer is pricey due to limited market etc? I don't know much about bandsaws but when I cut some pine with a mate the cut was wavey as seemed to be pushed about in knots? SAre you cutting different timber?

Hey,

 

Ive noticed it more with Softwood, but looking back at a stack of Oak I Milled I see its wavey too. Its more pronounced on the Softwood though.

I had a look at the Mill last night. Each of the Dips where at knots in the in 500mm wide Softwood Log I was milling. Dips down at the Knots, comes back up and settles out, all within 30cm. Then when the next knot is hot it does the same again.

Andy have you torqued the blade to the required settings as cant be a lot causing this.

Yip, torqued to the correct setting. Its an idicator on the B751, you turn the handle till the thrust washed meets a marked setting. Spoke to Logosol today, they said take the handle another half turn after this and maybe a little more and see if that helps. Do you get any waveyness when cutting through knots in your 130?
