SAE-8 Banjo Fitting Autocad

[tomrscott]

I captured a reasonably detailed drawing of the banjo fittings that JD uses on the 790 and others in Autocad and by several steps of conversion was able finally to get that into a JPG tha tI can upload here. If anyone wants the autocad or a dxf, email me at:

and I'll be happy to email it to you. /forums/images/graemlins/smirk.gif

Oh yeah, someone else may want to know the path I managed to get a jpg from Autocad Lt 97 (which does not directly export jpgs).

Nearly every thing I tried didn't work, Adobe Photoshop Elements, and Macromedia Fireworks are usually my graphic editors of choice, but neither could read any of the files that Autocad could write, even though some were supposedly supported. Probably the old Autocad formats are out of date.

Anyway, I finally found that I could write a WMF file from Autocad and then insert it as a picture into Powerpoint. From there I could save the Powerpoint slide as a JPG. Oh, and when creating the WMF from Autocad you have to pay attention to the command prompts, because it asks you to select what you want to export so you need to put a select window around the whole drawing. I missed that the first few times and wasn't finding the files because Autocad hadn't finished yet.

Now that I know a path to get Autocad drawings loaded, I'll post them of things I design as I get around to building stuff.

Here's something that might be useful for you, if all you are after is a .jpg of something so you can post it here. You can do a screen grab of the currently active window by pressing 'Alt-PrtScn' on the keyboard. This puts the image on the Windows clipboard, and then in any paint program you should be able to do a "paste as new image" or similar, just as if you had done a copy of something from within that paint program.
If you want an entire screen grab, use 'Shift-PrtScn'.

I was looking for a decent freeware screen capture program one day when I found this tip mentioned somewhere - no need for any screen cap program at all!

BGL990,

Yeah I have used that quite a lot when there is no way to print or save something from a program, especially error messages that programs generate and then you want to report the details to the vendor or a support person at work.

The trouble is that those seem to not be very good quality. I have generally pasted them into Powerpoint since I don't use paint programs much, but by the time you crop down to what you want and then resize it, the quality has fallen apart pretty badly. They get real fuzzy. If you just crop and don't resize it isn't too bad. Maybe this is a function of Powerpoint. I'll have to try pasting a screen shot into Photoshop or something and see if that works better.

In any case, I'd rather use a file conversion if I can.

Yup that works, only it will also copy everything else thats on the screen including the toolbars. One can just 'select' the area of interest and then 'edit' and 'copy'. That puts just that specific area into the clipboard which then can easily be pasted into Word, or a blank Photoshop canvas for size reduction etc. I've done it many times when making ads so I know it can be done. I currently use acad 2002, but am sure this will work with the older versions as well. Oh yeah, before you copy to the clipboard be sure to set the acad background color to white.

Well I guess this drawing is going to come in handy after all. Looks like if I want a banjo fitting, I'm going to have to fabricate it.

I cannot get the company in India who makes these to respond to my requests. I got one rather cryptic email from them in which they appeared to be saying they weren't interested in any small orders. I found one place (Summers Rubber Co.) that seemed to have some metric banjos with hose barbs that might have been close enough to work with, but they turned out to not even remember they had them in the catalog, didnt' have any stock, and couldn't tell me how much they would cost or how long it would take to get them (probably ordering from the same company in India!).

So I stopped by my local second-generation family-operated steel company (Newberg Steel) and bought a piece of 3/4"x2" steel bar stock two feet long. Cost about $12 these days with the price of steel, but that's cheap compared to the cost of fittings.

One thing that finally kicked me over the edge, was a decision that I will make one with a second tubing port located 90 degrees radially from the first port so I can TEE my second "return to tank" line into the existing line. I think that will actually be easier than making a TEE, as long as I am making the banjo anyway, and it will make for a bit cleaner installation. There was not going to be a lot of clearance for a TEE on that line anyway.

I'll try to remember to take pictures of the lathe work as I go. Might be interesting to some who've not run a lathe. They're fun to use, but my only resistance is that these will take a lot of tool setups and time, which I don't have that much of, but trying to buy them has taken a lot of time too.

Summers is in my back-yard. Are you sure that the banjo fittings that they have available can't be modified for your needs?

I would be more than happy to visit them for you. I might be able to get them ordered.

Pineridge,

re: "Are you sure that the banjo fittings that they have available can't be modified for your needs?"

Thanks a lot for the offer!

Actually I called this morning and the guy I talked to said they didn't have ANY banjos in stock. In fact he didn't even recognize the part numbers at first and questioned where I was getting the part numbers from (I was looking at the same listing you posted). He finally did find a couple of the numbers in the computer but said they didn't have any in stock, didn't have any costs loaded for them, and had no idea how long it would take to get some. I was hoping to get someone to take some measurements off of the hose barb shoulder so I could insure there was enough room to bore it out for 1/2" tubing. He said he would have to call me back and took my number. That was first thing in the morning west coast time, and I haven't heard anything yet. I think he said their supplier was overseas, I'll just bet they come from India.

I was considering getting an 18mm banjo and boring it out 1mm and then taking a die grinder and opening up the banjo bore slightly and maybe porting the hole just a bit to improve the flow capacity.

Or, I could use a 22mm banjo... If you took a 19mm copper crush-washer (19mm ID, 27mm OD) and centered it over the 22mm banjo hole, then take something like a large square or diamond shaped object and used it to peen three or four spots into the 22mm hole slightly, those peened-over spots would keep the 19mm ID washer centered over the 22mm ID hole and the ID of the washer would keep the 19mm banjo bolt centered. Then when you tighten the hollow bolt it would form a shoulder in the copper washers that would keep the bolt centered nicely in the banjo. There would be plenty of shoulder to make a good reliable connection, especially if you keep everything reasonably well centered this way. The 22mm banjo would certainly allow for plenty of flow.

Whether 18mm or 22mm (whichever had been available), I still had to make sure the hose barb shoulder had enough OD to be drilled out to 1/2" ID.

All of which seems to be academic if they've got to order them in small quantity custom for my order, it starts sounding expensive.

I am pretty well resigned to fabricating them on the lathe. Oh well, I enjoy lathe work. Just takes time. It will be fun to post some pics. /forums/images/graemlins/smirk.gif

In one regard, that stinks! On the other hand, an excuse to get away from the desk can be a good thing. Find it hard to believe that JD has these "custom built" would have swore it was off the shelf from someone.

OK, so ... one piece or two ?

I just got off the phone with the Akron branch of Summers. They have in stock the 16mm banjo fittings and are willing to order the 18 or 22mm sizes in quantities of as little as one. He quoted me a price of $13.00 for the 18mm to give you an idea of the value. If you want to call him direct for additional information the Akron number is 330-785-7303. These folks have always been easy to work with for any of our hydraulic needs.

It might be a whole lot easier than making them on the lathe but it's still your choice.
