Re: MIG Welding Newbie

For critical welds like this rear wheel shaft support I usually clean the metals well before welding by using a wire wheel.

@ JayL,

Bro looking at these pics, are you not going to do a full weld on the shaft support, meaning the angle iron being attached to the rear tubing. IF you are to analyze the build, the rear wheel is very vital here because it will be the one that will carry the most load specially the 59" gas tank if it is loaded to the cart.

I'm just concern with the right strength of the angle bar welded to the rear square tubing, that rear end if you will imagine will be carrying almost, said almost the weight of one full sack of rice, plus of course the weight of the cart and the welder, plus again whatever you will stack underneath.

Just trying to be cautious of what might happen ( hope it doesn't ), a weld or two might just
break or let go due to stress of heavy load. Anyway if you think the welds will hold for sure then let it be. :rolleyes:

OK, enjoy working on your cart, CHEERS

Re: MIG Welding Newbie

@ Rosy ... yes bro there will be more support and welds added. For now I still have to take off the shaft for machining the threads on the ends so I can fix the wheels.

I plan to install 2 more angle supports on the ends and then weld the shaft itself to the base. Adding more welds on the top angle bar is a good idea too.

Thanks

Re: MIG Welding Newbie

Bro Jay, there is a way that you can fix the wheels to the shaft without having it threaded.

This is just a suggestion, if you look at the 2nd photo, you can fit in a thick flat washer in between the rear main body and the wheel, maybe half an inch to an inch away from the body then spot weld to the shaft. It will serve as a stopper and spacer so that the rim and rubber wheel will not be touching the end of the tubular and the angle bar. :thumbup:

Now looking at the 1st pic above after let us say fitting the wheel on to the shaft, just simply follow it up with another thick flat washer but do not weld, and then 1/4" from the flat washer you can drill a hole sa shaft of about 1/16" or 1/8" in diameter, and then simply insert a locking pin or cutter pin and its done, wala pang gastos pag papa thread. That will make changing the wheels easier when the need arises. 😉

Re: MIG Welding Newbie

ako naman, opinion ko, by the time the wheels need replacement, you will be replacing the whole cart na.... spot welds would be fine imo also.

Re: MIG Welding Newbie

I got the washers already. Yes I reckon both ideas on wheel fixing will work just fine.

Re: MIG Welding Newbie

The Makita Dry Cut saw gets a blade reload specifically for the WIPs I currently do.

The Makita A-87242 blade is a very very good blade. I'm almost certain it is manufactured by Tenyru for Makita. More expensive than the Freud Steel Demon but it is not geared 100% for the metals I currently cut.

The recommended cutting thickness for the Makita is 3-10mm. I'm am only cutting max 1/4" ( 6.35mm ) and mostly 1.5mm square tubes.

The Makita has a thinner kerf of 2.1mm while the Freud is 0.114" ( 2.89mm )

Re: MIG Welding Newbie

The Freud is designed for 1/4" and thinner metals.

Perfect for 1.5mm to 2.5mm square tubes

If I need to cut thicker metals up to 10 mm then a blade reload to Makita will be done.

Re: MIG Welding Newbie

@V here are the first initial runs of the Freud Steel Demon. I'm a Freud die hard fan and I don't know why I tend to suspect that you are as well ..... but I could be wrong.

Even before I made the first cuts I already knew what to expect. The thicker kerf Steel Demon cuts better in thinner metals than the thin kerf Maikta. The Freud makes less noise as well.

1.5mm square tube

3/16" angle bar

Please don't ask me why. Probably somebody more knowledgeable in this can give an opinion.

However in fairness to the Makita blade it specifically says this in it's box.

I don't know why they don't mention this in the LC1230 dry cut saw specs or brochure but this is one main reason why I chose Makita over an Evolution or a Milwaukee saw.

It has a spring loaded blade deflection stabilizer. I saw it when I went to check the saw before buying. I also don't know if the other manufacturers incorporate one as nothing is mentioned in their brochures. Maybe it's standard or not. When I get chance to upgrade my wood Miter Saw I will check for this option.

@V does your Miter Saw have this stabilizer ? .... I believe it helps a lot to make the LC1230 cut true.

I know the Tein aftermarket car lowering springs are designed that when bumped harder it resist harder. If bumped softly it will adjust accordingly. There is a term for this spring but I forgot it. I suspect this Makita spring behaves like that.

Re: MIG Welding Newbie

Continuing the WIP now.

I plan to add these for use in mounting adjustable tank support add ons. There might be a need to change tank sizes later and probably incorporating this now can save hassles in the future.

Re: MIG Welding Newbie

Adding some rear add on stuff too ( don't know what to cal it LOL )

One Side option

Two sides option

I can later use these to hang angle grinders.

All mock ups are not yet finally decided ... please let me know if you have suggestions or opinions.

I also take time to run the metals in the bench wire wheel before welding. It's easier and can save me a lot of sanding / wire wheeling time when the cart is finally built and ready for painting.

An angle grinder loaded with a cup wire brush will also work. However the pieces need to be clamped first ( by vise or to the table )... an added step compared to using a bench wire wheel.

Best way is to make sure to buy un rusted metal stock but sometimes it's not always the case even if it's new.

To address Bro Rosy's concern for a sturdier rear wheel axle support I'm adding these 2 angle bars.

Will weld these flush .... needs some more fit up adjustments.

Re: MIG Welding Newbie

can't you just weld the axle on the cart? seems to be the easier and more logical path imo...
and just to be clear, you are building a cart right? not a truck? lol

LOL .... yes of course. A guy with no day time job to worry about has just too much time in hands to play around..... ODIY. Tagal tuloy matapos ng cart hehehehe

Re: MIG Welding Newbie

I think is time to look for another project, when you have something in mind to make, this gets done.... nice build so far... over but nice.... hehehehe

Bro JayL, adding those additional tubings on the rear will be fine as long as the attachments of the shaft is full welded or supported because of course that will be an added weight. By the way you may call it side support GUARD RAILS for your tank and yes you can attach a wire mesh on the sides, weld it with 1X1 inch angle bars then fit the framed wire mesh between the tubings, now you have an instant hangers on your cart. You can make some hooks for cables, clamps, angle grinder, wrenches and so many more tools. :rolleyes:

I think it will definitely be a very practical decision installing that GUARD RAIL, what do you think ? . The wire mesh on both sides will help you in a way organize your tools while welding. :superhero2:

Re: MIG Welding Newbie

Bro Jay, an over engineered welding cart is better than an ordinarily made cart., its safer and will give you peace of mind knowing your cart is a well made sturdy one hell of a piece. Just imagine the weight/load it will be carrying, with all tools too added.

I personally think its safer that way.
