Re: Rong Fu Industrial Introduction
On my saw (a Packard), the angle jaw has two mounting positions, and if the right position is used, it will cut 4x7.5" material.? I've never cut anything that big, but I have used the feature to cut wide material at an angle.

Re: Rong Fu Industrial Introduction
Yes, there are several modifications made by creative individuals
for their own saw.? The hydraulic downfeed is one, the is another example.? Some of these take an
individual a lot of time to set up and make once, but could have a
low cost to manufacture in volume.? If you offered them as an
"upgrade parts kit" with instructions, I think that could sell
well.? Even for people capable of making their own, if you're
making them in volume, you can probably sell the parts cheaply
enough that its not worth the trouble for us to make our parts.
Amazon and ebay could give you a direct to consumer channel.?
Your listing on amazon/ebay could instruct people to inquire or
pricing on larger quantities (which may be of interest to tool
distributors or importers).

Re: Rong Fu Industrial Introduction
Bill, I don't know whether Rong Fu take special precautions or not. Perhaps RF Sales can tell us what sort of QC they have around this?? All I know is that my first and most frustrating saw (a UC115) had it and I've fixed others.? I saw a quote a few years back, that 30% of saws had this problem, so even if the number is only a quarter of that quite a few group members will own a saw like this.?

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.

Re: Rong Fu Industrial Introduction
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.?
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
|
Re: Rong Fu Industrial Introduction
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

Re: Rong Fu Industrial Introduction
John. Thanks for the information. Very helpful. Howard
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
Howard,
Funny that you mentioned that.? I figured out how to do this in the vertical position but didn't think about the horizontal. On it now.?
Rick ? 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. 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
