Re: Laguna LT16 SEC Bandsaw Question

If I came off snarky, that wasn't my intent.??? I too, would value the electrical education.

David,

I agree that I do not want to bog down the saw. Actually, I would not have proceeded if it was my own project. However, as an engineer, I want to learn from every experience.

I really appreciate your feedback.

Can't help on the cap issue, not an EE, and I've never paid attention to the wiring of the saw.?

Whether it did, or didn't, shouldn't really concern you.? Bogging the down the saw isn't good for a number of reasons.?? Just don't do it - then it doesn't matter whether it affects the cap.? Put another way: are you going to continue to bog it down if absolutely doesn't affect the cap ? ? ???

Wood slicer give a smoother cut, but is quickly , I mean very quickly, dulled.?? Especially in rough wood.?? Those type blades usually only make sense for slicing thin exotic, expensive veneers, where the value of the wood made into sawdust is measured in real money.

Ash is pretty hard, and your piece is wet if it's a log.? Not an easy task. You shouldn't expect smooth fast sailing , despite what you've read or heard about laguna and RK blades.

David,

Thanks for confirming that the upper wheel is normal.

On the switch, I just wanted to confirm that me bogging the saw did not blow the start cap. I imagine with a centrifugal switch (opposed to manual switch) the start cap could be reengaged every time RPMs fall below a certain threshold.

I have the carbide resaw king which so far has worked great. I plan to try a wood slicer some day.

This saw is small but has no vibration and cuts 1/16 thin veneers with little variation. At least last time i tried it. I have resawn 2x12 Cypress successfully. All I am saying is that it has done what i need to do until yesterday.

The switches that ACM - Laguna uses are designed to be held in the on position until the motor comes up to speed.

The upper wheel should be loose, ect.?? Its how blade tracking is accomplished.

Re-sawing on these types of saws is not a speedy endeavor like cutting plywood on a tablesaw.?? Adjust you expectations somewhat.

1" is a pretty wide blade for that saw, you'd greatly benefit from 3/4" blade.?? The xtra 1/4" isn't bringing anything to your party - especially if you're looking for 'roughsawn'? look

Thanks Brett,

I do not recall sawing hard wood this big. It works well in soft woods. I had a mask on due to my neighbor being there so I did not smell it but later when I went back there was strong smell of burnt wood but the saw did not leave any burn marks on the material.

Too many odd things happened yesterday. I have not used the saw in almost 2 yrs. I will try a new blade next time.

I mostly want to confirm what I noted about the top wheel. Is it suppose to be wobbly or rigid as in pulley on a shaft.

Imran?

I am definitely still learning best practices in thick stock, but my experience leans toward your saw not having enough power in that motor. I upgraded to a stronger bandsaw because my 14bx really labored with 6"+ stock whether it was the load of the wood or overcoming the bind in blade flexing under stressful cuts. The new bandsaw is much better but still noteworthy how much slower stock has to be fed when it gets thicker,those gullets are dragging a lot of sawdust until they are free again. Next time try spraying some lube while cutting and see if it's the blade binding or the cutting load. RIP capacitor, too many of them being replaced and discussed recently...

I was cutting 7¡± thick Ash log pieces today only 20¡± long and it was harder than I thought it should be. I was using 1¡± wide 2 tpi steel blade because my neighbor wanted rough sawn look. I was pushing pretty hard and stalled the saw several times then the start cap blew.

Saw has a single phase 2.5hp motor and I have to hold the switch all the way (start position) until it is running and then let go. Switch is spring loaded and it returns to run position. So as I understand it, there is no centrifugal switch because I control the inclusion of the start cap in the circuit by holding the switch in start position.

Just wanted to confirm whether my stalling the saw had anything to do with the start cap blowing.

Another question. Before I started, I replaced the 1/4¡± blade with 1¡± blade and noticed that the top wheel was wobbly. This is as I was placing the 1¡± blade so no tension. I have not noticed this before and there was no tracking issue. Hindsight, I did not check for side to side wobble but there was wobble vertically, i.e., top and bottom of the wheel moved in/out in the same axis as wood is ripped. Is this normal and I just have not noticed it. It would not surprise me that I have seen this before and just don¡¯t remember it.

I am not sure if all of what happened today is somehow connected. Looking for wisdom from the collective.
