Machinists, anyone ever make a push broach?

[lil_Blue_Ford]

Yeah, I’m not a fan of powder coat. Seems like here in the rust belt, once that stuff gets a crack or scratch or something, moisture gets in and rust forms under the powder coat and takes it off in chunks. I’d rather paint, it’s easier to get at any rust and easy to touch up.

Wire wheel on an angle grinder is the best I found when I was stripping a old grille guard.

Paint remover won't touch it.

Everybody thinks I am crazy for hating the stuff but it is a nightmare to deal with.

Wire wheel on an angle grinder would be a preferred method, but I don’t have a midget angle grinder. Maybe I should look on Temu, lol

Maybe a dental supply store?

For some reason I was thinking we were dealing with external splines on a shaft.

What about a rotary tool, like a Dremel, with stone or carbide grinding bits? If you don't have one and plan on buying one, go with the True Value hardware store brand or an Habor Freight tool. I had a Dremel and was unimpressed with it's longevity. It burnt out about as fast as the Harbor Freight ones did. The True Value one I have now has held up a lot better and came with more bits at half the price of the Dremel.

You would probably burn the tool it out before you burned the paint off.

When I was stripping my grille guard with a wire wheel it seemed like I was basically burning the powder coat off by friction rather than the usual wire wheel method of ripping whatever it is you want to remove off.

I've removed powder coating with Aircraft Remover in the past. Not sure if it would still work these days due to EPA regs making companies change their formulations, etc..

That being said, a brazing or cutting torch would make very short work of any powder coat. Just steer clear of the fumes unless you like hospital visits.

It wouldnt touch the powdercoat on a Westin Sportsman grille guard around 2008.

Well, apparently the powder coat is the thinnest I’ve ever seen because it’s started flaking off everywhere but where I need it to.

Steel cuts with a file, just not real fast. It doesn’t skip or damage the file, just the new file doesn’t want to cut much at all time.

I have some pictures, I’ll get them transferred over at some point.

That is bottom of the groove to bottom of the opposite groove

Top edge to edge of the tapered groove.

Wondering if it would be possible to make a double sided broach and push it through 6 times with a shop press to fix the 12 splines

 

[85_Ranger4x4]

I think whoever made the thing should have finished cutting the splines there.

IMO it isn't made right. I would try to return it if possible.

Too late to return now. Originally I had thought of returning it and trying again but the family friend said he knew a couple machinists and could get it taken care of. Couple months later I got it back without anything being done. Then it sat here a couple months because I haven’t had time to deal with it. Now that the weather has gotten poor, it’s become a project for cold days in the shop.

I couldn’t find anything specific for my brush hog. Actually couldn’t find much of anything in relation to information or parts specific to mine. The company is still in business apparently, but the models have changed and old information is hard to come by. Gearboxes have changed with the newer ones. Blades and bolts are still apparently the same but the rest I dunno. I sourced a 12-spline of the correct measurements (at least the measurements listed) and there was a vague reference that it fit my brand (Howse), and it used the correct blade bolts. Closest I was able to find. Made in China of course. It fits on the shaft, just the angled sides of the grooves are slightly too narrow to fit over the splines on the shaft.

My old stump jumper is bent and the bolt holes are egged out. I like the thickness of this new one in comparison, much more sturdy, I just need to make it work.

 

[lil_Blue_Ford]

If I really wanted to (I don’t), I could cut the center hub out of both stump jumpers and swap it. Be a bugger to grind out the weld and it appears to be a press fit as well. Makes me wish I had a mill or big lathe.
