so I was using the band saw add-on today cutting some free-hand hearts out, it is Valentine's Day of course... anyways the blade(which is NEW and SHARP) was coming to a stop, as if there was not enough power to keep it going, I could also hear it wind down some as it cut the wood.
what is the cause, or idea for fixes? Could it be the part in the second pic? Is it possibly not set properly?
EDIT: the coupler from the power to the band saw is fine, tight and power unit is locked into place, I can spin the couple to get it going again...
EDIT #2: THE JOB IS DONE! ALL FIXED, WORKING ORDER!
Rele,
Wellll could be several things. First it looks like the blade may be too tight. If you are using a 1/4 inch blade your tension is too tight but that would not cause the machine to stall. My first inclination is that the poly V belt in the headstock may not be adjusted correctly. Check the tension of that belt. Also the band saw will stall if you are trying to make too tight of a radius cut and the blade is binding at the back of the cut line. Use a narrower blade or make wider turns. Other things can cause slippage, such as the tires on the bandsaw wheels being hard due to age. Some belt dressing that is sold for fan belts at Auto supply stores can correct that problem. In addition the drive and poly V belt can also become dried and not grip as well. Belt dressing here can also help. Let us know how you make out.

The guide bearings in the second pix looks strange. Is the blade actually between the two bearings. It should only be riding in the small groove created by the beveled edges of the bearings. i.e. the bearings should be tightly against each other. It there a blade tooth broken off there?
The embossed aluminum blade cover in the first pix looks like it may be bent, but that has nothing gto do with this 'problem'.

I did have the motor open for oiling today and the belts are GREAT, not hard or cracked. Seems almost new actually.
Didn't by any chance leave some oil on the pulleys?
Question is, is the bandsaw slowing down, of is it the headstock slowing down?

ya, that is merely an illusion, I just double checked as I had also notice the oddities of the blade and those bearings. The blade is not missing a tooth nor is it sitting between the bearings. The bearings are flush to each other and the blade is riding where they meet.
The piece of aluminum was bent but it was also an easy fix, LOL!
Is there a spot to oil up the band saw like there is in the motor housing? I wonder if that might do the trick, there is a slight squeal sometimes coming from the band saw addition. Also when I turned it on this time, it took about 3 seconds before the band saw blade started to move. YIKES!
Also there is a note stating that the band saw is not to be turned on higher than the "D" setting, which is labeled as jig saw, is that optimal setting for when using the band saw?

nah, no way oil got near it, and I tried to hold the headstock part with my hand to see if it was giving but I was unable to hold tight enough before friction on my hand made me let go. LOL!
I think it might have been turning too tight in the wood, but then again it does stall when first turning on... sooooo!

The bandsaw does not have an oiling point but the top wheel has two needle bearings in it that should have a small quantity of quality wheel bearing applied. Not a whole lot but just enough to hold on your fingertip.
You may want to try to start the bandsaw with the cover removed to see if the lower wheel runs and then the blade catches up with it. It could be that the tires on the wheels are dried out and have become glazed. Also make sure that the drive hub on the headstock is tight and the set screw is seated on the flat of the shaft. Those hubs can work loose and cause a similar condition.

right on, I left the side off, and started it up, I had to re-fasten the drive hub to hook it up and it is tight, I will watch for the lower wheel, but I am sure they are glazed over, shall I just wipe them down?
Also there is still grease on those bearings, I noticed when cleaning, although they have a coating so fine saw dust on the the grease, the grease is still there and seems to be plenty, definitely not dried up.
Okay, I ran out there again and fired it up, fine, but then I decided to grab the plastic coupler from the headstock to the band saw and I was able to stop it with little force really. What is the conclusion?
