BX25 3PT Modifications?

Could you use shaft collars? Put a grease fitting in place of the set screw.

That would work as a last resort as the bushing welded into the support piece and is anchored to the pin with a bolt to keep the pin from drifting. Fot the 1" long one I would just use two end to end. Most colars, as I remember, in that size are no more than 1/2" long. Its an option. The top pin for the curl cylinder is 1 1/8" Dia so may work there also.

All, thanks for the ideas. We will hit something this week one way or the other.

You got me thinking. Ruland corp makes shaft couplings that are a lot longer than the collars. They are 1215 steel which is cold rolled bar stock same as the pins. I can cut to length. Thats the beauty of this forum, we get the solutions one way or another. Thanks all. If bushing stock is not available at a decent price I will go with the couplings. The screw holes can either be cut out by length or actually will not affect any thing.

Ron I "might" be of help if you can give me the exact Outside Diameter of
the pins. Do you have a pair of calipers?

Is it;

.75"
.74"
.73"

or

15/16"
7/8"
13/16"
5/8"

or other?

The FEL pins are 3/4 and 1 1/8 per my HF electronic calipers.

Pipe ID is too loose a fit for a lubricated shaft assembly, it would create too much play up and down on the pin.

So, we have 2 different sizes to deal with, 0.750" and 1.125"

What is too much slop for you?
Rememeber that when you weld those bushings are going to move.
The tighter the tolerance the more perfect you must be welding.
OE builders have the luxury of a jig, unless you make a jig you might want
to keep it pretty loose. It may be plausable to use a long piece of DOM,
weld the brackets to it, THEN cut the tube afterwards. THAT would work
well I think, so long as your sawzall skills are up to snuff.

DOM tubing will probably work just fine for you. (Drawn Over Mandrel)

For the .0750 / 3/4" pins I might consider 1-3/8" OD x .250 wall x .875 ID.
.875 ID - .750 OD = .125" Slop, if centered .0625 all the way around.

For the 1.125 / 1-1/8" pins I might consider 1-3/4" OD x .250 wall x 1.25. ID
1.250" ID - 1.125" OD = .125" Slop, if centered .0625 all the way around.

If that will not work for you CLICK HERE and look for something tighter or looser.

If it is a BX25, I believe the FEL and BH are made in the states and I
believe it all to be US measurements, it is possible DOM tubing sized
METRIC might work if your not satisfied w/ my suggestion. I do not
know where to buy such and animal.

I am thinking out loud here for I will eventually want to make my own
something or other, be it a BH bucket etc. I would want to tap in some
zerks I think. I recently pulled some tiny lil threaded zerks and found
those tiny lil taps to be a pain, well, whoever originally installed the zerk
I was working on blew it and drilled to big. I drilled it out and obtained NPT zerks.
It worked MUCH better.

Artisan,

I am not worried about set up or distortion if I use at least 1/4" wall bushings. I have a long piece of CR 3/4" shaft that I will use to line up all four bushings on the bottom connections. Also have a piece of 1 1/8 shaft to line up the curl connection. Waiting to hear on my inquiry on the bushing stock. If it becomes too big a hassel I will settle on using the shaft connectors I discussed earlier. That seems the best option so far. Being an old!! pipe fitter/welder I am confident in my welding skills to keep everything lined up and spot heat to bring alingment back if required. As I weld I will keep moving the line up shaft to keep it straight. I will use step reamers and a pipe reamer chucked up in my drill press to make all the holes . First hole will be 1/2" with all four (2) brackets oriented with each other and tack welded together. Then ream each individually. The pipe reamer will give me the bevel I need for full penetration welds starting out with 3/32 6010 for the root. I weld hotter than most so that root pass is key.

Will start a new thread as soon as I start taking pictures.
