I know the answer to this question.....

[myxpykalix]

is that it would be easier to do what i want manually with a handheld router.....
however i'll ask anyway....

A customer wants me to cut like 30 pairs of these at a time and also round over the edges. My first thought was to do a profile toolpath with a pointed roundover bit first.
Then mirror the part like i flipped it over, make a toolpath for the flipped part. Flip the part manually on the table having made 4 holes on the corners for registration pins. Run the flipped part toolpath with the roundover bit.

Then take and do a profile cutout of the part.

Then I thought that was too much work and figured i'd just run a roundover bit in a laminate trimmer manually around the perimeter....:(
Now if someone has a better idea....i'm all ears, or in this case "eyes":rolleyes:

Jack,

Not that I am an expert on the Shopbot yet but if I was going to do more than 1 or 2 at a time on the Shopbot then I would do the roundover on it. I have done that on pieces that I make 4 or 5 of and it works great, I just have the roundover cut on a line then I profile cut. Yes I can do it on the table router afterwards but why?? I make Fly Tying Bench's that I sell on Etsy and eBay and I now cut everything on the Shopbot and only have to sand and assemble. They are made from hardwood.

All depends on how much you're making and what the 'bot can be doing otherwise.

For me it makes far more sense to roundover on the router table as the 'bot can be busy doing things that I can't do by hand. I can roundover a great deal faster than the 'bot with a lot less setup.

Supper Nice Fly Tying station. You should contact one of the big sporting goods store and see if they would carry your product in their stores.
Really good work.

Jack,

I think it boils down to quantity. If this is a one-off project, use the router table. If this is something that is going to be a production operation, take the time to program the CNC to do the work for you.

Just my two cents.

Yep, router table and half hour or so should round over both sides of 60 pcs. You could spend a 1/2 hour just figure out how to flip them and register the parts for roundovering (new word).

However, if this were a production item then I would cut the first side with a round over through cut bit. Then have a puck with a "dual negative" of the part to drop the part into for positioning. i.e. the puck would have an oversized negative by maybe 1.5" larger than the part. In that would be a tight fitting 1.5" negative with cabinet door handles on it that was just fitted into the larger negative. Drop in the part, turn on the vac, remove the 1.5" "frame" using the cabinet handles and run the toolpath. I would have an xy zero reference point on the jig.

Hope that makes sense.

Jack,

I do sports plaque cutting for a local company. The plaques are MDF. I have to do some cutting/carving on one side and the other side needs to have rounded over edges.

After a lot of consideration and figuring out exactly how I would zero everything, decided to just cut the parts out then take them to the router table to roundover the back side. Saved a lot of time. I can round over a sheet of 75 to 100 parts in about 15 minutes on the router table. Figured out to the minute that this took less time then doing flip operations on the CNC.

Just my experience.

I would agree with doing them on the router table since the roundover is on the other side and that is all that is being done. On my Fly Benches, everything in on the top side so while they are secured, it's easier to do each operation by just changing the bits. I do 4 to 8 tops (all pieces) at one time out of 8' boards. The bottoms are glued up with raw outside edges ( why clean that up) and I do the cove cut first then the profile. We have some mods we are working on to put some recessed rounds in the bottom to hold beads, etc and that can be done quicker and cleaner on the shopbot... BTW, any advise on the divot size for a pipe stand? Need to make one for my father-in-law for Xmas..

Because, i worked thru and came to the same conclusion most of you have.....
I just wanted to see if you were as smart as me!!:rolleyes:

Actually many times when i ask a question, i (think) i know the answer but to be sure i need your validation.....

But just as many times, i don't have a clue:eek: and need your experience and wisdom and help:)
