Re: FB710 bandsaw survival guide

 

Hi Mac,?

The FB-710 utilizes a single sheave/pulled, which drives a poly-V belt roughly an inch wide. Happy to get some measurements or part numbers later if you're interested, working on-site this week so away from the Shop.?


John, I can't speak to your S540P but adjusting the pulley on my FB-710 was a ~10 minute operation. I measured the relative distances from the motor pulley and wheel pulley to the rear of the cabinet, released the pressure on the belt, loosened two grub screws securing the pulley to the motor shaft, slid it a couple mm (can't remember if it was forward or back), confirmed both pulleys were the same distance from the cabinet, secured the grubs screws, applied tension to the belt, and haven't had any squealing or vibration issues since.?

Re: FB710 bandsaw survival guide

 

Thanks everyone for your advice,

I have cleaned and put dry molly on all the guide bearings and also adjusted the blade position as noted along with resetting all the guides. It seems to work better but will also get the Felder technical to adjust the motor pulley as it is squeaking on start up. Hope to make some cuts on Monday and will let you know how it goes….we have been locked down here with flooding these last 2 days!.

Many thanks?

Hi Colum,?

I have a FB-710, hopefully I can help. I'm running a 1-1/4" Laguna Resaw King. I originally had the blade centered on the wheel and was experiencing some drift. I read the owner's manual (gasp!!) and saw that Felder recommends that for wider blades that you have the teeth hanging off the front of the front of the wheel. I adjusted tracking on the top wheel, got the teeth hanging off the front of the wheel, which solved my drift issue.?

On a side note, I was experiencing some squealing on start-up and vibrations during running when I first received the machine. It turned out that the drive pulley on the motor shaft was slightly out of alignment with the lover wheel pulley. All it took was loosening two grub screws, shifted the pulley 2mm forward on the motor shaft, and it fixed the issue.?

Re: Engineer question regarding beam size

 

6 meters is enough of a span, that I would consider having a structural engineer look over the design.

?

In your image, it looks like the brick walls extend out a bit into the shop.? Are there steel beams at that location?? Can you key into vertical steel beams in the walls ?? What will the connections be at the rear wall ?? Will you have a stairway up to the loft ?

?

It would seem the connections to the walls would be the critical design issue.? As the others here have mentioned, published span tables can guide you to the appropriate horizontal beam sizings.? Transferring the vertical load into the walls is where I would get professional engineering guidance.

?

I agree with John Hinman, you might consider doing a bit of math to estimate the total load more accurately.? Any permitting jurisdiction is going to want that number.? In addition to vertical loading, there is shear loading from wind on the structure, etc.?? (I am assuming no earthquake loadings at your location.)

?

Good luck with the shop build-out, looks like it will be an awesome nice shop to work in !

Typically for floors we talk about capacity to support loads in terms of weight per unit of area, in the USA that would be lbs per square ft, psf.
After you determine what that design live load is, along with the length of the joists the beam is supporting, I might be able to size an lvl for you if you are not in the US. ?I am only licensed to practice in a few states. ?
Previous suggestions that some lumber yards here can also do this are accurate, but they still start with what live load is being supported. ?
John’s comment about the beam being supported by brick also raises concerns.?

Also, beams can “fail” in ways other than falling down… ie they can deflect so much that they fail in terms is servicability. ?We typically design for a live load deflection limit of L/360, which for your 6m beam is about 17 mm, or 5/8 of our silly inch.

You say the mezzanine would carry “a ton” of material. Do you mean a ton as in 2,000 pounds, or a ton as slang for “a lot”? For a 6-meter (20 feet) space 10 feet wide, 2000 pounds works out to 10 pounds per square foot. (Sorry for the imperial units - I am in the USA). Lumber storage could easily go up to 150 or 200 pounds per square foot, or more in localized areas. For reference, that is about a 3 or 4 foot tall stack.

Re: Engineer question regarding beam size

 

Hi Chris,?

It has been my experience that any lumber yard that sells LVL headers will have access to the engineering software to determine header sizes.

One advantage of having the lumber yard spec the beam size is that they'll typically provide a drawing, rendering, or some other document showing that it is appropriate for the opening and loading. This is helpful if/when the assembly is inspected, as I've found building inspectors to be much more tolerant of a document from the lumber yard versus a homeowner pointing to a span chart they found online.?

The other advantage of working with the lumber yard is that they can get creative with the header sizing. For instance, if you have unlimited height they might specify a 16" tall single LVL, whereas is you have limited height they might specify three 8" tall LVLs.?

Hi Chris,

There are a lot of tables with the info you seek. I have a book at home but I am out till end of the month. There is going to be a bit of flexibility in beam selection depending upon the amount of deflection you can live with. For obvious reasons,?this deflection is kept to a minimum if the space above was a living space but a bit more deflection may be acceptable for storage.

Main reason, I am responding is to share what I did for this exact situation. I built the beam in my loft (above the floor) such that the ends are supported by the structure below. This allowed me to built a vertical storage in my loft while keeping my 12’ shop ceiling.

Here is a short clip showing this storage. I did the video for insurance record so was not intended to show the beam but you may find it helpful.

?Hi there everyone.
I a wondering if anyone would know what size beam I would need to span 6m to support a timber storage loft in my shed I'm renervating. See pictur attached. Beam would sit on brick each side. See picture attached. I estimate there would be about a ton of timer as storage spread along the span.

I know it's a bit cheeky to ask this question in here, but I'm know there are a lot of smart people in here who would know this info.

I have a k700sp coming at the end of May and want to get this installed above it before it arrives.

I'm hoping to use an LVL (as apposed to C chanel) as it will be easy to mound adjacent framing to it.

Thanks,
Chris.

Re: SCM FS 41ES/52ES

 

Hi David,?

You are correct, I forgot that the out feed table on the A 951 L is not a parallelogram design. That being said, it should be easy to adjust and hold its settings.

Sorry Tom, but I beg to differ. ?The A 951L is not a parallelogram design - at least not in the conventional sense. ? The infeed table employs a parallelogram system for height adjustment, but the outfeed table is not, and relies on the same cam-actuated system for height adjustment as the other machines in the Felder jointer lineup. ?I know Felder likes to describe it as a “parallelogram design” but that is a half-truth. ?

That said, since it does not have flip-up tables, The A951L and Plan 51L stand alone jointers should not suffer from the same design/alignment deficiencies as the other Felder J/P combos or the A941. ?For anyone interested, you can find a discussion of all this in the document here on pages 8-9: ??

The FS-52es is a relatively simple, straightforward machine, no bells/whistles, but that's why I selected it. If you want some more creature comforts I'd suggest you look at the FS-7, I know PK really likes his.?

Re: Felder widebelts - any good?

I have a Timesavers series 1300 single head machine that I purchased used from a wonderful gentleman in Northwest Oregon. ?It is a single belt machine with a 37” width capacity. It has very low hours, and is essentially in new condition. ?I use it for pretty much anything that will fit in it. ?Belts are easy to change. ?My 3hp dust collector, purchased from the same gentleman, is just adequate for this machine. ?

Timesavers was good to talk with before and after I purchased the machine, despite the fact that they did not sell me the machine. ?It is the only wide belt I have owned, so I have little to compare it to. ?However, It serves my needs well, and is problem free. I would purchase it again. ?If I had any regret, it would be that I would like to have a wider machine.

One caution to consider. ?These machines are power hungry. ?My single head machine requires a 240V 3 phase power with a 90 amp breaker. ?The spec’s say it draws 53 amps at full load, and would draw 100 amps if it was a two head machine. ?I would have had to upgrade my electrical service if I had purchased a two head machine. ?And I would have had to go with a larger dust collector. ?

Good luck with your search,
