Building a rock rake what should the spacing between tines

[Gofast]

I just looked at EA thanks.

I have angle iron for the tines I really like this design for connecting to the angle iron.
I could add one more support in the middle.
This design is great if I ever decided to add wheels later down the road.

The tines imported from Italy have arrived. All 62 pounds of them.
I just ordered to the 56 (100) bolts to put this together.
I hope to get to work on this built over the weekend.

I made some progress. The front of it is done. It is mostly 2" x 2" 1/4" square tubing.
The main boom is 3" x 3" and I have all 56 3/8" holes drilled.
My bolts come in tomorrow and two hole saws coming in on Tuesday.
I bought Nylock bolts so they don't come loose on their own.



I have work for this rake to do and I would like to get it finished. No one local had the hole saw size I needed so it will take a little longer to finish it.

To help place the tines I use a baluster spacing application

Looks pretty good. Interested to hear how it works after you get finished and use it.

Can you give us the link of where did you ordered the tines please?

I bought them from AgriStore because they have free shipping. My tines were $140 shipped.

I made some progress last night. I mounted the pipe that holds it. I drilled it for the position pin.
I welded some 2" x 2" 1/4" square tubing on to my angle iron. That should keep it from bending.

Looks good. Any progress? I am thinking to start building it too. But most likely I will use C-Channel. Its easier to set it up to the CNC Plasma to make the holes, instead of drilling all these by hand!

I used a drill press but it still was not fun drilling all those holes.

The rock rake is very close to being done. I am going to add kick stand and I need to paint it other than that it is done.
It was raining today so I could not test it out.

The angle can be adjusted five positions forward and three positions backwards.



Once I get it outside, I will get more pictures.

It looks good man! Great job!

Thanks. I used scrap yard steel. The project cost $200 to built. Most of the cost is the tines and the bolts.
It is pretty heavy duty there is 1/2 plate under where it the pipe holds it together.

I put some paint on it.
