There are a few threads here regarding the design of the new frame (https://github.com/MaslowCNC/Mechanics/wiki/The-Default-Frame-Assembly-Guide) , but now as people are getting their new kits, and will start building them, I think it would be helpful to have a thread where people can post their experience building the new frame using the wiki instructions, and post any questions or problems they have.
Reading those instructions again, I see that the bill of materials calls out two sheets of 3/4" plywood. One sheet is used for the back but the second sheet is not mentioned again. I’m guessing it’s meant for cutting out the sled but can @dlang or @madgrizzle confirm?
I’m not entirely sure of the intent of the two pieces of plywood.
The frame was designed so that the plywood wasn’t a structural component (it could stand and work on its one). This way, you could install a spoilboard out of whatever material you desired directly (plywood, foam, etc) to the frame.
So… if you were going to use the first sheet as a spoilboard, you’ll need another sheet to make a temporary sled in order to cut the round permanent sled if you are following the directions. This might be where the second sheet of plywood came from. Note: you can make the final sled by hand if you can cut a circle… you don’t have to make a temporary sled and then use maslow to cut a final sled. In reality, it doesn’t have to be round… you just want it not to snag on areas that have already been cut-out. I think @bee had a design for an octagon sled. The real key is to round the bottom edge out so there’s no sharp edges.
That’s exactly right
You cant have too much plywood
I recently built my frame according to bars bolt together design. It was a fantastic cheap experience. I did alot of hole drilling with my battery powered drill. the end product is surprisingly portable and compact when only partly broken down. makes for easy storing too! I am hatching a plan to replace the back spoilboard with something lighter / cheaper but have yet to come up with a better solution. All in all, Im glad I went with the bolt method.
How about a picture?
My thoughts exactly. Last night I think I figured out a template system that will let me use this as a one-step-to-done solution:
I’ll start a new thread about it when I do so this stays on topic.
I thought about using the same thing. Its pretty inexpensive, round and has smoothed edges.
Do they offer a thinner version? Giving up a full inch to sled wood does reduce the travel available for the z-axis. That circle would get you up and running quickly, though!
Sadly, no…but maybe somewhere else does? Moving Table Sled discussion to its own topic here:
Well, we (almost) all have a router, and could pick up a cheap rabbetting bit.
Practice on scrap first…
I am currently in the process of building the new “default Frame” . I am about an hour in and the frame is 90% done (need to attach Rear cross member and top beam). Lumber for the Frame was about 40 bucks from home depot i had screws, glue and plywood
- I really like the cut list- minor suggestion is to have what cuts are from the 8 footers and which are from the 10.
- The approach of measure very little and using parts as spacers very helpful
- On the attaching the Back leg to the front leg- i put my screw in a bit to low so when it pivoted it had a corner sticking out. quick fix with a saw (see picture
- The mirroring of the second leg took a minute to think thru the picture was very helpful
- Make a suggestion on the screw sizes i used 2 1/2 inch seemed fine.
- Also point out not pressure treated- this may see obvious but lets make it as easy as possible.
I apologize for what may be a dumb question, but your lumber looks to have much squarer edges than what I ended up with. Is there a prefix that makes it different from what I’d otherwise call a 2x4?
Haha, No sir Claudio. theyre just regular old 2x4’s. maybe its my new camera making things look extra sharp
not sure if you were asking me or Gallagher but i am regular old 2x4 as well. Edges are rounded.
