Welding axle spindle

admin

I am needing to weld a 1-3/4" diameter axle spindle on to a 1" thick piece of plate.This will be on a farm implement and no harm will be done if it breaks other than the inconvenience of fixing it again. The spindles will be loaded to near their max  capacity of 1500 lb each and will travel over rough ground on a daily basis. Obviously I need to get these as straight as possible.Do you think I can get a strong enough weld just butting the spindle to the plate and making multiple passes or do you think I will need to cut a 1.75" hole in the plate and stick the spindle through thus being able to weld on both sides? Obviously the latter would be stronger but it will make it more difficult to get it straight.
Reply:If you drilled a hole with little to no clearance it should square it up for you...provided you drilled the hole perpendicular to the plate. Are you planning on putting any gussets from the plate to the spindle? if you are planning on running some gussets I see no need to run it thru the plate in this application.If you were to just bevel the end and weld it to the face of the plate without gussets I would definietly tack something to it and the plate in a couple places, otherwise it's going to really pull on you as you weld.-DoogieMiller 350PMiller Trailblazer 325 EFI w/ Excel PowerLincoln LN25 suitcase welderXMT 304/22a feederMiller Syncrowave 350LXMiller EconotigHobart Handler 140(2) Uni-Hydro 42-14Hypertherm 65 plasmaWEBB Gap bed lathe
Reply:I don't have any way to drill a 1.75" hole in 1" material. If I ran it through I would be torching a hole and thus a sloppy fit. This is why I am concerned about getting it straight.I need to study it more tomorrow but I think there is only an inch or two of the spindle before I get to where the bearings/seals go so there is not much room for a gusset or brace to hold it square.
Reply:even a couple of 1.5-2" gussets would greatly help, placed at approx 10 and 2 O' Clock.-DoogieMiller 350PMiller Trailblazer 325 EFI w/ Excel PowerLincoln LN25 suitcase welderXMT 304/22a feederMiller Syncrowave 350LXMiller EconotigHobart Handler 140(2) Uni-Hydro 42-14Hypertherm 65 plasmaWEBB Gap bed lathe
Reply:Otherwise like I had said just temporarily tacking something to it, 90deg from one another to keep it pulling in either direction would work. You definitely want to bevel the end tho, and use multiple passes.-DoogieMiller 350PMiller Trailblazer 325 EFI w/ Excel PowerLincoln LN25 suitcase welderXMT 304/22a feederMiller Syncrowave 350LXMiller EconotigHobart Handler 140(2) Uni-Hydro 42-14Hypertherm 65 plasmaWEBB Gap bed lathe
Reply:Blow a hole in plate a ruff 1 or 1 1/2" diameter, and then plug well axle stub to back of plate thru hole....It ain't got to poke thru the plate in perfect sized hole to get advantages of backwelding it, and you won't shorten axle stickout.
Reply:Cool. Thanks. I will try to do the gusset or the temporary brace and I also like the idea of the back plug weld. I will trace around the spindle where I want it and then cut the hole out leaving the line so it still sits flush on the plate and then I can weld the heck out of the backside as well.Last edited by Drilldo; 03-17-2015 at 01:33 AM.

Reply:How about drilling a hole large enough to line with a section of .125" wall DOM tubing.   Press in and pin the spindle into the tube.  If the spindle breaks in the future, pound in a new one and move on.    This way your now heat stressing the spindle.
Reply:Drill the hole it will make squaring it up easier and be stronger. You want a gap in there anyway.  Most implement wheels on farm equipment are straight through and welded. Set spindle in hole and hold off center a little to allow tack to pull square. When to square where the first tack is , directly across from it tack again. Those two tacks work as a hinge to allow you to square ninety degrees to those. Set spindle square and tack and the immediately tack directly across from it. If using stick use 6010 for first penetrating pass and cap with 7018.
Reply:Rent a Mag drill if the plate cannot be brought to a machine shop. Get the annular cutter you need for the size. It will take about 20 seconds to drill through that plate with that annular cutter on a mag drill or on a Bridgeport Mill (again if your plate is mobile).www.tjsperformance.comDynasty 300 DXHTP 240HTP Microcut 380Hyperthem 85JD2 Hyd Bender and HF Hyd Ring Roller all in one =(Frankenbender)Bpt.

Reply:The gussets need to be under the spindle so they are in stretch, not compression, when loaded!

Reply:Originally Posted by DrilldoI actually own a mag drill but I do not have any rotabroaches that big. I am not going to go buy a $100 bit for this one time job. I am going to torch it and weld. I might add I have never seen a spindle like this break off at the weld usually what happens is the bearings are neglected and then get damaged and tear up the spindle in the process thus needing replacement. The replacement spindles were $15 each. I was just looking for some tips on the best way to weld it up not necessarily the best overall way to do it. The machine shop or mag drill holes are great ideas as is making it a press fit but all involve more than I want to spendon the project especially in this application.
Reply:I do this all the time with the spindle when I build hay caddy's ... no hole is necessary 3 gussets at 2, 6 and 10 ... 45 degree gussets and it squares it self up. I do put a bevel on the spindle end burn in a good root and over that finish with 7018Hay caddy's support the weight of the disc mower and run 5-10 mph in a hay field ... havent had one fail yet.Last edited by blueriver; 03-17-2015 at 02:45 PM.Located In SE OklahomaLincoln Mig 135Hobart Ironman 230 Mig5x10 CNC Table with DTHC & FTHypertherm PM65 on the tableMiller Bobcatwww.caneyagequipment.com
Reply:For squaring the spindle I've use a piece of tubing that slides over the spindle. Run axle but down onto tubing. So long as the tube is square spindle should be square. Clamp it down and weld the backside. I'd do that if you're torch cutting a hole all the way thru. Sent from my iPhone using Tapatalk
Reply:if it is possible take it to a welding shop and just get them to drill you a hole, you can save a lot of money if you welded it!But large drill bits are expensive!

Reply:I'm with "farmshop" on the hole!I use bi-metal hole saws in the drill press all the time for the large holes.
