Materials

Post by Atonwa » Fri Feb 05, 2016 11:24 pm

So I've gone in and talked to most of the machine shops around me since I got my S3. I offered to buy some of their scrap material from jobs they run and I'd say half were willing. Usually I'll get a call about twice a month when they run something they think I can use. I've always offered money but most of the time they are happy to just get rid of it.

Today while I was in delivering a drawing for my Routakit I want them to make the owner surprised me with this.

1" thick UHMW scraps, 30 sets of them and a bunch of 1/8 and 1/4" thick plexiglass

He also handed me a 1 gallon paint can of carbide cutters. Most are still pretty sharp and will work for roughing or profile cutting just fine.

Since a major cost of operating is materials and tooling does anybody else have any tips or places to look for cheap materials?

Your the first person I thought of when he handed me the UHMW. I thought to myself "Now I can just mill out my gears" :D

Yea the carbide bits were a score, we all know first hand how much we spend on tooling.

I've just made a few parts out of HDPE and Seaboard (branded HDPE) with single "O" flute cutters and it's been great. That can of cutters is astounding...

I found another source of materials that most of you may have access to and not even know it. After seeing the price of aluminum from McMaster and some of the online places with shipping added it's really more than I would like to spend especially for testing. I asked around and someone mentioned trying the metal recycling places. He said sometimes they set the plate and sheet material aside.

So a quick trip to my local recycling yard and asked them if they sell aluminum scrap. Yes they do and also steel, brass, bronze, etc. Since I was there I asked if they happen to have any aluminum extrusion as I can always find a use for it and the stuff is $$$. So $87.53 later I come home with this! It's definitely worth a trip to your yard, they have bigger sheet material but it wouldn't fit in my jeep so I will need to go with my trailer and then take it to get sheared at a local shop.

The scrap rate on aluminum is .53 cents a pound. That aluminum plate was 30 pounds but I didn't catch what the rest ended up weighing. Just thought that was a pretty great price for all I was getting so I didn't ask any questions 8-)

1/2" thick x 12" wide x 51 1/2" long 6061-T6 Plate
45mmx45mm extruded aluminum frame with 4 heavy duty locking casters
Misc 45x45 extrusion and hardware
(2) 45x45 x 8' extruded aluminum with hardware
Brand new aluminum white board :D

If you do add 1-meter Z clearance you really could mill trees now. :)

Or even do full car body parts. Carbon fibre lay-up anyone? :D

Local Macy's in our mall going out of business and they are selling everything including the furniture and fixtures.

Grabbed 21 sheets of 1/2" thick 36" X 36" cast acrylic and a bunch of 1" and 2" thick.

Who wants a custom Shapeoko acrylic waste board :lol:

Hmmm, that might make for a good safety type enclosure for your Routakit HD thing, just in case the new spindle spits something out at high speed.

eg broken end mill, something getting caught, etc.

That's a good idea but I think I would have to make the frame more heavy duty, these things weigh probably close to 50 pounds each. it would definitely make the S3 more stable as a waste board in the base rather than MDF.

I bet you could build a heck of a sound absorbing clear enclosure for your Shapeoko with this!
