I have to agree with your assessment. My shop owner just raised the fee for me to use the water jet which makes this option more expensive. The laser is a more affordable at this point and I plan on going this route.

I sent the drawing to DYDD in Windsor. They quoted me $360 CAD for waterjet. Is there a benefit to laser vs. water? Is one more accurate? I read laser was normally cheaper but, is that the only practical difference? Thanks guys.

As far as the accuracy goes, either water jet or laser is good. The water jet does leave striations on the edges. Laser may leave a slight burr. Neither is major though.

Hi,

I have access to a waterjet, powder coating, and discount metal. Once I create my grinder, I could provide materials to those wanting to build this grinder.

I do have to pay for time spent using the waterjet, so this would be factored in. By the way, I live in MD.

Leon,

Where in MD do you live? I'm in Harford County.

- I will give some feedback shortly (in the next few days).

- I have only just found this project, and I am digesting the information. I have Waterjet, CNC-Plasma, CNC-Mill in house (I own)...

- I should probably not post much yet before I read all the information ... but ... I do think I understand the parts pretty well after looking at the drawings and several pictures that I found.

- There is a lot of room to gain "economy" ... by not simply putting all of these parts in one process to cut.
--- Spacers -- these are going to be a major source of your cost (and pain).
---- my mind is whirring to think of a solution ... but one solution that comes to mind quickly is to use 1/2" square bar --- or 3/4" x 1/2" bar ... and drill the holes in them.... another thought is to use DOM tubing ...

--- The base plate (parts on the drawing in the 17" x 13" box ...
---- the ones on the left are common dimensional steel (2" x 1/4" bar)
---- and the base plate should simply be sheared at your metal supply house (or plasma cut)

--- The outside of all the other components for sure are good candidates for CNC plasma ... the holes might benefit from a different process... I have plate markers on my CNC table that could/would mark hole position for drilling or punching.... I also have a spindle on the plasma that could drill. They could also be drilled on the mill.

--- Holes in plasma "Can" be done very well by some machines and operators.... but others will have a hard time with them.... you will not get consistent results from plasma on your holes (from different machines / operators).... All CNC plasma machines are not equal ... and all operators are not as apt ... You will not find a lot of novice or beginners running waterjet machines..... but I will say that the Majority of CNC plasma (regualar air plasma) is not as experienced...

--- I have every intention of building one of these machines for myself, and as I progress will be able to give you more information.

- I was working with the 11" long platen file last night -
-- I hope to have some time coming up to get more detailed with it, but I just had my son run some basic numbers.

> Cutting the whole file (the 3/8" parts).... just "plopping it in" at Quality 3 = around $427

> If we reduce the quality on the outside edge (will still be awesome quality)... and increase the quality on the holes... it lowers the price about $100 bucks... and should produce a better result --- it shows around $325

> If I delete the 1/2" x 3/8" x 8" Qty = 12 spacers ... it lowers the price about another $100 ... so gets the cut cost down to about $225.

> I am going to be playing with it a little more .... I did price steel ... a sheet of 4' x 8' x 3/8" steel costs me $232 + tax .. It will take about 1/5 of a sheet ... so the 3/8" cost should be about $50 ...

> Cutting for myself doesn't cost for me so much.... but just trying to give some info for those that are working with cut shops.

> I will be cutting some of these for myself in the coming future... if I can ever get a little free time...

Leon,

Where in MD do you live? I'm in Harford County.
Kevin,

I live in Howard county. I apologize for delay in getting back to everyone. Bow hunting season started and fishing is at it's prime. I plan on cutting my grinder on the waterjet shortly after which I will have a more accurate idea concerning cost to produce my grinder. I will post an update once I assemble the grinder.

Good morning, Leon,

I know it's been a few months, but I was wondering if you still have access to a waterjet and metal. I too live in MD! Thanks in advance!
