Re: ENDS SUNDAY - Ryobi 1600 psi electric pressure washer (small and portable) $80 at I picked up a refurbished unit last year for about $60. It's been great for small jobs, no complaints at all. I used it last weekend to clean the house siding. It ran for 5 hours almost nonstop and did a...

For what it's worth I've found (most) OEM Stihl parts to be reasonably priced and a lot higher quality than the aftermarket versions. Fuel lines/filters in particular are definitely not worth cheaping out on. If I were replacing a piston/cylinder I would look at aftermarket options but for...

I wouldn't want sawdust all over my machine tools

Very cool, thx Doc. BTW, I used to read your forum religiously like 20 years (sheesh ...) ago. That purple Rainmaker you made was one of my favorite custom markers of all time :beer: Glad to see you're still doing what you do.

Does it really matter if the rear of the blade isn't perfectly aligned to the shoe? The front does the cutting right? As long are you aren't getting kickback/pinching in the cut I don't think the rear makes a difference. That said, with a .25" difference I don't see how you couldn't be...

I used some screen door rollers kind of like these on my cabinet doors. They ride on a piece of aluminum extrusion fit into a milled slot on the bottom frame.

I suggest a corded 7.5" circular saw (even a cheap skil model) and a hand plane for trimming. Then, a work bench with a vise to hold the work. That's really all you need. People will say that hand planes are old fashioned but I still think that cutting close to the line and trimming exactly...

Interesting, so how is the hydraulic pump(s) driven? I've never worked on one of those older bobcats with the clutch steering, that looks really complex.

Great info, thanks guys. On the black rose inventory page it lists Price (cwt) - what does that mean? -edit- nvm, that's easy enough to find the answer to. It's dollars / hundred-lbs.

Mine is bolted to 2x4s sitting on a harbor freight anti-fatigue floor mat. Cheap and very effective

Killer, thanks! I can't believe I missed that project in all my google'ing. Reading the thread now

Cool, thanks! The hydraulic section looks very helpful. I also found a great page of handy equations here: http://www.womackmachine.com/engineering-toolbox/formulas-calculations.aspx

I'll have a relief valve in the system to protect the pump and motors. The only real risk I think is that the pump just won't develop enough hydraulic force to move the machine under load or break wheel traction for turning. Still not sure what size motors to try. :dunno: Is there any risk...

Thanks everyone for your advice. The biggest constraint will be the pump which I already have (link in OP). It doesn't deliver much flow or pressure, but it was super cheap and works with a vertical shaft mower engine which I can also source cheaply. I'm trying to develop the most torque I can...

Nice, cast iron at home is pretty ambitious. Please put up some vids if you get it sorted

Thx for the input A_Pmech. Sounds like I'll need come up with an accurate estimate on the total weight first and foremost. I was thinking that the wheel motors used on ZTR mowers might at least be a good starting point. Does anyone know what type and displacement of motors are typical there?

So in the spirit of engineering discovery I'd like to build a small skid-steering hydraulic vehicle - something around the size of a Toro Dingo or similar. I'm planning to use one of these tandem pumps for the drive system...

Anyone have a video on this process? Do you have to desolder any pcb components, or is just a plug and play deal? Sent from my HUAWEI Y536A1 using Tapatalk

I think it's worth spending the extra $5 for the "Heavy Duty" version. http://www.harborfreight.com/4-12-in-5-amp-heavy-duty-angle-grinder-60372.html AvE on youtube took one of these apart recently and was surprised and impressed.

The low pressure means it's incredibly slow. Which means it's using a ton of abrasive per inch of cut. The costs for even small projects will be way too high Sent from my HUAWEI Y536A1 using Tapatalk
