Axle/chassis stands

admin

hey all (from Australia)here is a little project i have done over the last 2 days....slow and .....well slow haha... nothing compared to most of the stuff here but I have to start somewhere rightBackground: Carpentermachine: BOC(made by Kempii) single phase (240v) 250a GMAWgas is argosheild run @ 15 litres/min wire is 0.9mm (.035)Base material is 200x200x8 flat plate (8x8x0.3175)Main upright is 65x65x6 shs (2.5x2.5x0.236)Internal/adjustable upright 50x50x5 shs (2x2x0.196)Top support for adjustable upright TFC 100x50x5 (4x2x0.196)Gussets cut out of 90x6 flat bar (3.54x0.236)I drilled the holes with a magnetic base press (holemaker) 20mm to suit a 19mm pin and clevis, unfortunately I broke the cuttter and cant get another untill tomorrow to finish the holes gussets and top supports were oxy cutplease feel free to cretique any of the work as Im here to learn...Ill try and get the settings used, I know the wire feed but the voltage isnt shown on this machine it just has 2 knobs, coarse and fine, both 4 postions.....cheers,Serg Attached Images

Reply:Idea…I am planning on building an axle stand for myself.  I was thinking of mounting a “chain vise” on one of the stands to hold the axle.  This could be a handy feature if your into setting up gears or installing brackets.  It’s a Jeep thing.  BTW: Nice welds...http://www.google.com/products/catal...d=0CDUQ8wIwAw#

Reply:Good looking welds Husk2100.  Glad to hear you'll be using the stands on a Rover  I've got a '95 Disco that's been teaching me alot.Jeep thing?  I had that Jeep Thing once, and it burned when I pee'dHey, did BOC buy out Migatronics?  I had a Migatronics (also made in Sweden) wire feed in the '80's and man that thing would run butter smooth, even wired for 120v.Last edited by dubl_t; 06-14-2010 at 06:57 PM.Lincoln SA 200Esab Caddy 160Thermal Arc 201TSMiller Dialarc HFI don't like making plans for the day because then the word "premeditated" gets thrown around the courtroom....
Reply:hi dubl_t,AFAIK, BOC here in Oz contracted Kempii to build their single phase (our 240v) GMAW in their top range.....I believe that kempii do not offer single phase GMAW only 3 phase (415v)I really wanted to get a WIA (Oz made)but the local dealer here sucks balls....to put it mildly...my BOC250c runs nice, but im not sure about a few things like how often to replace tips and liners etc? so not sure whether the little problems are me or the welder????  I have no problems (well good enough for a newb) welding on 5mm up but not very good (crap) on the thiner stutt, especially if welding to different sizes together...Ill get a pic of a trailer tailgate I welded last night...4.5mm to 1mm.....not flash I know alot is technique and settings, but it gets frustraing when doing an acceptable weld and then doing dog poo95 disco hey  bet its nice having full time 4wd and a locable center diff...V8 i guess?cheers,Serg

Reply:Billdacat,nice Disco, looks like a safari gaurd front bar.. and while it does appear to be recovering the jeep, it doesnt look like it has gone through the same bog......unless it picked a higher line.
Reply:Serg,Pretty smooth looking welds.   But suggestion and hint:  Try to not put stops/start on corners if at all possible.  On the upright posts to the base plate, run the bead -around- the corner and stop there.  Move your position and/or the workpiece, clean up the stop popint, and then continue welding.  There is typically a lot of 'stuff' going on strength and material wise at the corners already, so you want to try and not have any more 'stuff' going on at the coreners by having a weld bead start/stop there as well.  Same thing at the top of the gusset plates to the upright tubes, try and run the bead -around- the corner and not have two stops right at the tip of the gusset plate.  Another way to do the bead at the tip of the gusset plate is to run it long and just go a little bit straight past the gusset tip.It's a little bit tough to tell from here, but I'm not sure your arc dug through the steel to get some nice deep penetration into things.  Look at picture #2 in Post #3 above and what I see is the bead sitting totally on top of the gusset plates (especially in the right hand bead in the picture) and not penetrating into the gusset much.  It could be the lighting and the picture or the way you ended the bead, but it looks a bit 'iffy' from here.Also, even with a max of 250A, putting even a slight bevel on the edges of the gusset plates and the end of the upright tubes would help to ensure better penetration of the weld into the steel.  See picture #4 in Post #1 above, no bevel on the edges of the gusset plates.Also, it is not good practice to have a notch or other discontinuity in stressed items.  See that little notch on the edge of the gusset plate in picture #1 in Post #2?  That is a built-in stress concentration right there.  Fill it with a bit of full penetration weld and then grind it all smooth and even or at least smooth it out with a radius instead of the straight notch.  Granted, it will -probably- never come into play for some moderate static loads on those axle stands, but why even have a correctable defect in there at all.

Reply:MoonRise,thankyou for your tech tips, this is exactly what im looking for.  even though these are simple axle stands and they will far exceed the weight put on them I feel these types of things are "practice" for the important stuffstop start I never thought of....all i did was try and roll the weld around the corner a little and finish it a bit thinner so when I started again on that point it got into it and not built up to much....each up right was welded twice ie do 2 opposite welds then put to one side and do the next stand, when those 4 were done start with number 1 and do the 2 remaining welds and so onthe gussest are only 1/4 plate and I am under the impression that this welder at full settings will single pass upto 3/8..... I was on the higher settings and pretty much spray transfer (I think)Ill have to dig up the voltage chart and seeregarding the pic2 in post 3....the angle between these to is not 45degrees it is quite shallow as the radius on the upright blends away from the gussest...it was almost like doing a butt weld... I know there isnt much reinforcing metal(weld) above flat but it was bloody hot going in...my glove and hand can atest to that...it is very hard with photos of welds I took way more but these showed the best I felt....once agian Ill dig up the settings and post... that may help regading the strees riser in the gusset YES, bloody oxy slipped sideways....those little wheels dont turn so well and seem to have spatter on them...guess I need to grease them up hahahaha....But will weld it up and clean over.Once again thanks for taking the time with thisSerg
Reply:the welding is super for the purpose,but i dont care for the design at all. the bases are way too small for the height of the stands in my opinion. it looks like the vehicle could be pushed off the stands too easily.

Reply:just a suggestion about the jacks for the axle:First) put wheels on them, 400 lb axles don't move easily on jacks without wheels.second) as a clamping mechanism U-bolts work great (on the vehicle and on the stand lol) and thats what the local shops use. chain vice idea sounds good too."...My pappy was a pistol I'm a son of a gun...""...God is great, beer is good, and people are crazy..."
Reply:Serg,yea v8/auto Disco.  Wanted the 5spd but kinda rare over here.  Not REAL rare, just kinda.  No moonroofs, no leaks No real pics to post, got it about 6mo. ago and not quite into pic worthy transformations.  I might have some up on Discoweb or Pirate.Dammit, see what you've done.....now I'm late for work!Lincoln SA 200Esab Caddy 160Thermal Arc 201TSMiller Dialarc HFI don't like making plans for the day because then the word "premeditated" gets thrown around the courtroom....

Reply:went out to the garage and checked the "store boughts".small stands are 7 1/2x 8 1/2 for a 12" high that extends to 18". the large stands are 10 1/2 x 11 1/2 for 16" high that extends to 24".

Reply:Originally Posted by husq2100I was thinking about this as well....the bases are 8 inch square...I tipped them by hand and the actually have to lift to tip over....also the vehicle on them is a static load....scaffolding and arco props use bases of same or smaller size and they are alot taller and even have more load on them...looing at my rig which weighs about 5000lb thats only 1250lb per corner....is there a ratio of height to base? how big do you feel they should be?cheers,Serg
Reply:Originally Posted by StroutyScaffolding is tied together, so it acts as one unit to resist tipping over.  I would want the bases a lot wider, just so you don't end up wearing whatever you put on them.
