Hi, Everyone in , we're new in here and would like to introduce our self to all of you. We're bandsaw and Mill/Drill maker from Taiwan. Rong Fu is not a new company , it starts since 1975 with only 10 people, main product is vise. By 1979, we were also producing 4-1/2" metal cutting band saw and for the domestic and overseas markets.
It's been over 40 years company, we have a lots of product but mainly still producing conventional bandsaw & Mill/Drill machine, our business expend globally, business with over 40 countries, north US,Canada, European...are our main market.
Challenge always exist no matter how we fight with market, it won't go away especially the competition very high in the conventional machine tool industrial like us. China machine maker is another challenge, Rong Fu will still keep going on and remain the same faith to offer best machine to our global customer!! check our web site to get more information

Hi, i am sorry to disturb you here, just want to let people know us more, we have 5x6 bandsaw machine in our production, we're come from Taiwan. Would like to collect market information for the small bandsaw. We're looking for owner of small bandsaw, we will not keep post useless information here~~~

Hi.? Welcome to the group. This is a community of users. We probably aren't going to buy direct from the manufacturer in quantity.? I'm quite impressed RongFu has reached out to this group of enthusiasts.?
Fellow members;?What would you have liked with your bandsaw if buying again?
Vertical cutting: I would like a better solution for vertical cutting position eg: a small built in plate for small cuts, and a larger one that is easily clipped on to the smaller plate (easy enough to make, but would be a nice accessory).?
Blade alignment: Better instructions or some sort of set up tool to enable the blade to cut straight.?
Any other ideas?? Melo

Hi, Volumetrico:
Yes,you are right, seldom manufacturer will do so. Come to any group or forums seems meaningless action, IF they want to do some commercial advisement. However, we're here for a better possibility to design a new small bandsaw in the near future! you mentioned you need vertical cutting solution, and table for that. I have to admit many small bandsaw owners have similar point of view, we collected many owner's opinions at below link, it is a question survey just to summary owner's opinions, Can you help to fill it? some of question you may interesting! Just take few mins for you but give us big help for re-design a better small bandsaw

re: "Any other ideas?"
I think a popular option would be a low cost hydraulic downfeed
that would bolt up without modifications to saw, or only required
simple modifications.? If they wanted to sell accessories direct,
either Amazon or Ebay would be a fine choice.

It is nice to see a manufacturer take an interest.
I would also recommend you check out Mr. Sparber’s site where he documents his mods to his band saw.
I don’t see him listed in the directory any more so he may no longer be a member,
but some of his mods are genius.
Many would require very little on the manufacturing end to have “built in”.

The idea of accessories that easily fit on eBay would be great.? The
better vertical table, downfeed, jaws for holding small items, lubricant
pump, things like that.
My biggest problems with my bandsaw (HF brand) aside from getting one
that wasn't broken into pieces on delivery was the idle wheel bearing
had been pressed on over the painted shaft.? The over tight fit caused
the bearing to be damaged so I had to replace that early on.? Also, the
"4x6" bandsaw wouldn't actually cut 3x6 metal.? I had to fabricate a new
vice jaw.
But, it does cut very straight and cleanly.

As others here have said, search Internet for "4x6 bandsaw mods".
The "magic" will be to find a way to increase quality of the saw without increasing price, or increasing price just a bit.? Things like the grade of bolts and nuts used for example. I had problems with blade tracking on my HF saw and found the factory bolts in the upper wheel adjustments were all stripped. Also, the plastic adjustment handwheels for blade tension and movable fence adjustment broke quickly. Adding some electronics to sense blade temperature and adjust saw speed automatically would be cool, and to sense if blade stalls.

I would love to have some type of adjustment to square the vertical cut which is my biggest gripe with my saw. I saw how others pretty much re-machined their saw but it should not be that way.

Rick The primary adjustment for horizontal squareness of cut comes from the joint between the sawframe?and the PIVOT ARM at the left-hand rear of the saw. Do not move the fixed jaw out of parallel with the pivot shaft, or you'll ruin the vertical squareness you've achieved because the arc of the blade is moving in 3D space.?? Slightly loosen the two 5/16" bolts that clamp the joint and ease the direction of the joint fore and aft with a soft hammer to swing the line of the cut in the direction you want. Be careful - its?effect is counter-intuitive, and VERY sensitive, so its easy to move the joint in the wrong direction and to move it too much. If you can't?get enough movement, then use a rat-tail file to open out the slots in the pivot arm to give yourself more adjustment.? If your saw has eccentric bushes on the guide rollers on the inside of the blade loop, you can use that to adjust horizontal squareness by moving one in one direction?and one the other way, but it screws with the guide roller separation and vertical squareness if you run a wide guide roller gap, so is not the preferred option - jv

John, ? Your email is much appreciated, and the timing is perfect. ? With the saw in the vertical position, I was aligning the fence to the blade. That is far easier and potentially less destructive than turning the blade guide assembly. I can see that the more the blade guides are turned along the blade’s major axis, the more the blade must twist, which can’t be good. ? As I started to address Howard’s request for alignment in the horizontal position, I built a bar with an adjustable slope. It addresses the blade twist just as I did in the vertical position. It was then that I noticed that the cut on 1/8-inch thick aluminum plate was an arc. As I was scratching my head of that behavior, your email came in. ? I’m not too keen about adjusting with just a soft hammer. I would prefer to have a pushrod dial test indicator on that joint, so I know where I started and how much I’ve moved. If not too complicated, a pair of set screws would be a nice way to adjust the joint smoothly. ? Lots to learn here! ? Thanks, John. ? Rick

Hi Howard Yeah the trick to getting these saws to cut square in both horizontal and vertical directions at the same time is: 1.Do? horizontal squareness 1st, by setting WORK parallel to the pivot shaft in Plan View - looking from above - (i.e fixed vice jaw is parallel to shaft), then setting sawblade square to the pivot shaft, also in Plan View (i.e with joint between pivot arm and sawframe castings) 2. Do vertical squareness 2nd, by getting work parallel to the pivot shaft in Front Elevation - looking from the front of the saw over the vice table - (i.e vice table has to be parallel to the pivot shaft and also not humped or hollowed) and the sawblade square to the pivot shaft, also in Front Elevation (i.e by twisting of the saw roller guides). All of these are adjustable except the vice table parallel to the pivot shaft, which is part of the way the saw was made (boring the holes on the pivot ears parallel to the vice table and the casting not warping after machining).? Lots of work to correct, but it is possible The saw CANNOT cut square in both directions unless both these things are right at the same time.? When they are, these saws will cut all day long at better than 3thou" per inch of cut. To get it this good you need a sensitive squareness test, which?is detailed in 'Buying a Used 4x6 Bandsaw' in Files section -? /g/4x6bandsaw/files/Buying%20a%20Used%204x6%20Bandsaw%20v4.pdf?This is all a Royal PITA (mumble grumble). If Rong Fu are going to re-design the saw, they could do us all a favour by making saw-cut squareness part of the way the saw is made, so it cant be set wrong! . I'm still making my list of things I'd like to see? - jv
|
Hi Rick
Try something like this.? Packed out with washers between the casting and the adjuster on the side and the end to get the right adjustment range.
Push-pull along the joint, and just push on the other axis which I've not had to adjust so could be left out - jv
|
Wow John. Looks like you've spend many hours studying the saw and we benefit your experience. I think the major problem of the saw is the parallel alignment of the pivot shaft?to the top of table. I thought of boring the hole larger on one side where the shaft goes into the table casting and turn an eccentric bushing with slots for a spanner. It takes so little movement to get it parallel but I don't think there is not enought?"meat" in the casting. This is the only adjustment you cannot tweek. There were times when the saw cut was good enought?to do the job but I had to machine so it is 90 degree. Annoying waste of time! Oh well. Should have picked a rich wife! Hey John. Are you on the 9x20 lathe forum? you name is familliar?to?me.?

No Howard, just the 4x6, oh and used to be on BuellXB.com when I had a Uly.
I think your fix would work with 3 setscrews to centralise the bush, then inject epoxy to fix it in place.
But we're highjacking RF Sales's post, other than mis-bored ears are definitely something for them to engineer out completely.
I'd really like to see what other mods people want in a fresh saw design - jv
