Where am i going wrong with bandsaw?

There's a video on YT with the video description is below. Looks like it could be related to your issue. This is also a Sabre 450 bandsaw.

"When trying to mount an original Record Power 3/4" (19 mm) blade the tension system all the way up still wasn't enough the have enough tension on the blade. By contacting Record Power the factory adjustment was pointed out as the option to still have the blade properly mounted. In this video it is explained and demonstrated how this can be done.Bandsaw: Record Power Sabre 450Blade: Record Power 3/4" (19mm), 3 TPI, L=3885mm, t=0.8mm"

Kinda wonder what Record were thinking about with the factory setting being too short for the specified blade length.

Make sure the blade guides are set up with the back of the blade touching the thrust bearing. Keep the guide bearings off the teeth of the blade. Don't force the wood through the blade, let the blade do the work, as they say. And, has your piece of wood been put through the planner to ensure a square edge between the table and the fence. Obviously, is the fence square to the table and blade.

I also have the Sabre 450 but don't have the same problems with veneers. I was using a Tuffsaw Sabrecut (3/4 inch 3 tpi) blade which made short work of ~300mm apple trunks, although the cut quality was a little rough and needed cleaning up afterwards. Your blades are the correct size for the 450 (3886mm) so tension seems a good place to focus. The YT video @Fitzroy posted earlier is a good watch. Note the alignment of the teeth on the apex of the wheel - this is also recommended in the Snodgrass videos and should ensure the teeth of the blade are the least likely part to wander. You can also see how much slack he has in the blade before tensioning - way too much.

All good tips above especially having the blade run on the rear bearing. As a last resort clean the blade by holding a chisel while the blade is running ( avoiding the teeth obviously ) and also use one of those lubricant sticks - they make a surprising difference.
