Inner Diameter of Hole Too Large for Press Fit
Hi. I have an aluminum piece with a hole. There was a tube pressed into
that hole, but I pressed it out and want to install a different tube. The inner diameter of the hole is slightly larger than the new tube that I want to press fit into the hole. The new tube can be inserted into the hole without a press fit, but it does not rattle around. This is not a tight enough fit. It has to be a press fit. I am hoping there is a tool to reduce the inner diameter of the aluminum hole so that the new tube is a tighter fit. From searching around, it seems that I may need a knurling tool. I have a 20 ton shop press, and I am hoping to find something that I can press through the hole to make it a smaller hole, causing a press fit for the new tube and aluminum piece. Does anyone have any suggestions on what to do? Sorry to not list a real e-mail address, but it is to avoid spammers. It is goteverwhatyouneed at yahoo dot com. Thank you very much. |

A knurling tool will not work if the assembly needs to be sealed. This is because of the way the knurling works. The metal is displaced from one area to another. The knurling tool for inside knurls looks like a screw. So part of the diameter will be smaller but the other parts will be bigger. This method may be OK for valve guides in engines but probably isn't any good for your application. Loctite makes products to glue cylindrical parts together. Done correctly the finished assembly will be as good or better than a press fit. Try a web search for the proper product and a local fastener supplier to buy it from. ERS |

Jwho If you intend to slip the mating tube into the "too large' hole only once, and you dont want to invest in a knurler. you might try this crude method. Punch the surface of the tube thats slightly too small with a center punch. Put as many punch marks as you feel necessary. But you must punch enough marks to make the tube a press fit. Get some Loctite intended for locking bearings into their sockets and apply to the punched surface. Slip the tubes together and wait for the Loctite to set. Jerry |

Here is one more idea. You can snug a hole by tapping a ball bearing that
is larger than the hole at the mouth of the hole. Another way is to drill and ream tapered holes around the diameter of the hole and to tap in taper pins to these holes. When reaming the holes with the tapered reamer, ream every other hole and then ream the remaining holes from the other side of the work piece. Or perhaps an easier solution would be to make a tube with a larger outside diameter. -- __ Roger Shoaf Important factors in selecting a mate: 1] Depth of gene pool 2] Position on the food chain.

The fit doesn't have to be watertight, if that is what you were referring to. I saw a bunch of knurl tools at Knurlkraft. They just looked like a little wheel with some grooves on the outside.

"DanG" wrote in message news:e6A4f.4496$OM4.1727@dukeread06... Here are 2 more ideas: Install the tube. Use a center punch on the plate holding the tube, punching a series of dents around the tube. This should swage the plate material tight to the tube. I would still add the Loctite. Does the problem lend itself to installing the tube and driving a tapered pin/swage tool inside the pipe to swell it outward to the plate? This could perhaps be done to the tube before assembly, but maintaining tolerances would be tricky. Perhaps a combination of both.

It has to be a press fit. I am hoping there is a tool to reduce the inner diameter of the aluminum hole so that the new tube is a tighter fit. Why not expand the tube? Can you fit a #6 cap inside the tube? -- Free men own guns, slaves don't www.geocities.com/CapitolHill/5357/ Hi. The new tube is steel, and the piece with the hole is aluminum, so I thought it would be easier to make the hole smaller. Sorry to be ignorant, but I have no clue what a #6 cap is. The tubes are about 30mm or so in diameter. The inner diamater is around 10mm or so. I'll have to check that and report back. A #6 cap is the fuse activated detonator for commercial dynamite. They are about 8mm in diameter and the shock wave should expand the tube. 10mm wall thickness is a lot, you might have to use more than one.

I'll have to pass on that method. |

Basically you drive a pin into the hole of the tube and that causes the tube
to expand in diameter a bit. The pin will have a tapered end on it so that it starts into the hole without forcing. Lubrication is a necessity when doing this! If the tube is going to be permanent and is a tube just for price conserations or weight considerations, I'd just find a ball bearing (or turn a similar pin) that is large enough to force a good fit and drive that into the hole of the tubing with a press and you will have a nice tight fit. -- Why do penguins walk so far to get to their nesting grounds? |

Couldn't you just drill the hole bigger and press in a bushing sized to
fit both the hole and the tube? This seems simpler than many of the other ideas. |

Hi. It's a strong stress area, so I think that won't work. It is motorcycle steering parts. I have been too busy with work to get the pictures taken, posted to my website and links posted here. The original hole is 31mm+, the original shaft is 31mm+ (about .005" - .007" larger than the hole), and I am wanting to replace the original shaft with a different shaft that I have yet to get measured, but it is reported to be smaller in diameter than the hole by .002" or so. When switching to the different shaft, I am hoping to maintain a similar fit with the original piece. I guess it needs to be .007" - .01" smaller in ID. I still have to check it out and make sure, though. Thanks. |
