Way to go Nils, :)

Congrats Nils! Let me know if you need some pointers on shoveling snow! I know a little about that. :);)

Well do Nils!

X'mas came early for you this year!

Wish orders like these keep flooding in!


#PS,
I know who to talk to when I start cutting acrylic

Thanks to all for the nice comments. My logistics side is working over time.

There has not be too much white stuff. I have found that I can use my dust collection which has helped some and the rest I clean up and return so it can be recycled.

I was breaking up the remains and putting it in a garbage container for recycling but I have stopped breaking them up after each cut because it was taking too much time. I now leave the remains of the sheet and stack them. Just doing this has allowed me to go from cutting two sheets per hour to three. See the photo.

I am currently cutting the 3/16" material with a 65-012 bit but I am going to try today a 63-743. I have had good results with the first one. I have cut 32+ sheets with one bit and it is starting to get dull. The 63 is made for plastic so I hope it will cut longer.

I cut in one pass and I am running at 130 IPM with the router at 18,000.

The displays are going to a discount department store gearing up for the holidays.

Nils have you tried faster cutting? Im not cutted acrylic lot, but i had feedrate 5500mm/min at 18K spindle speed ( thats about 210ipm) Tool i used was 4mm one flutehttp://cerin.it/Scheda41a.asp?ID=930...ti=4&NPrezzi=1 I agree that faster speeds give worse cutting quality, but when it isnt so important then you may try. Time is money :)
How you did fix sheet on spoilboard, i do not see on picture any screw hole.

About tool wearing. Im a lot cutted here PE sheets, and i think that you can cut with one bit about 30-40 sheets is normal.

big job - congrats! what is your timeline?

Nils,
Can you post a picture of the completed parts assembled? Just curious. :)

Nils, It looks like you could save some material by nesting the parts a little different. Have all the pyramid looking pieces on one sheet and all the circles on another sheet. I just bring it up because of the material in the corners and in-between the pyramids.

I'd second Russell's comment.

Even if you aren't paying for the material you still have to handle it, get it delivered, stack it, put it on the table, remove it, dump it.

looking at the photos you could do as Russell suggested putting circles on one sheet and pyramids on another

How about nest all the pyramids on one end of the sheet and put the circles at the other end of the sheet. maybe try rotating the pyramids 90 degrees to see if the leaves less waste.

Russell's idea will leave less waste because you loose a lot at edges of nested circles where the straight edge of the material means you have roughly semicircles of wasted space all along the edges.

Russell and John,

I appreciate you comments but the job is being done in a way that produces the combination of parts that the customer wants and the way they order the units. There are thousands of ways that the units could be cut. I could put multiples of one part on a sheet and have 5 different sheets for each unit but that is not suitable to the way the customer orders the units and efficent use of my time.

The customer is happy and it works for me. Plus the remaining material is not wasted because it is being recycled and the customer is getting a rebate on the recycle.

Please I am not interested in discussing this further.

No problem http://www.freesmileys.org/smileys/s.../surrender.gif

John,

You can put your white flag away. Hope your building is going well.

Ummm, I don't think that's a white flag Nils. Take a closer look.

Maybe John needs help with his laundry. :)

Enough stirring the pot. I'll go away now. Not all of us are as busy as Nils. ;)

Greg

I didn't want to go there but what was the guy thinking that created that!:rolleyes:

springbreak? :D

Very Interested
 

I will be watching closely as your project develops i am close to starting to build my table and purchase the next big price tag bits as my shop is finally poured and done

Rails question...
 

I know you purchased the rails and added them to your aluminum angles. You bolted them on. I was wondering if using the tape or epoxy or Gorilla Glue would work to hold them on rather than bolting.

Just curious.

I dont think you would want anything short of many bolts at regular intervals, due to the downward and side forces involved here.

The down force is not carried by the fixing method....only the sideways forces are a factor. I suspect that a bonding method will work, but we need test experience.

IMHO, the rails risk more from external force due to foreign object knocking on it accidentally... Bolt & nut is a good guarantee.

Jack,

I like the idea that the machined rails are firmly attached to the Aluminum L piece which is firmly attached to the C channel. Yes, it is more work to secure with screws but I caution on the side of being firmly attached.

In that case, would the compliance of the thicker vhb tape that we norally use be Satisfoactory or would it show up in cut quality?

MBA All-Star Logo
 

Last week I cut 8 Sheets of 0.75" Ultra Light MDF for the MBA All-Star Logo. The game will be played in Orlando. My client delivered the Logo on Tuesday (1/3/12) and tonight it was on the local evening TV news.

I will try to post the pictures.

Nice work Nils!

Well done Nils. It did turn out great and will look good in your portfolio.

Freakin WOW !!! Great stuff !!!

Nils,
Great work - as always.

For those just considering a machine build.
Nils machine was the first to utilize the BWC pre-made vee-rails attached to aluminum angle substructure.
7.2 : 1 OM Gearmotors, gecko 203 drives
Milwalkee router (and soon a spindle)
....super work buddy!

Nils: I know you told me that you were doing the logo , but you sure knocked that out quick. looks really great. Jimmy

Just so every one knows, I cut the letters out and my client designed, put them together and painted the sign. It was pretty neat to see the sign on the local TV news.

My client did a great job with the design and painting.

Thanks for the nice comments. Our machines can produce some neat things that others can enjoy.

Nils, so are you going to an air cooled or water cooled spindle? What size? What is the main reason for the upgrade?
Just curious. :)

Well done.

Absolutely Awesome!! The sign looks great well done !!
Very High profile end client being the NBA

Once again Well Done !!

Cheers
Tony.

What they said Nils.
Impressive.

Regards
Ross

Congratulations. That is one lovely sign.

That sign looks great Nils. Love what you are doing!

Muy Lindo Nils (very nice)


Pablo

Good looking signs Nils

Thanks again to all the nice comments. I learned that they may want an even large logo. I will post photos if that happens.

Nice job Nils; thanks for sharing.
