Track routing with Maslow-cnc 0.7mm bit

Post by kiklo »

At last I have started with my new track. A first with my Maslow-cnc.
Here is a picture of how its going to be. I'm using 600 x 24000mm (2x8) wall MDF panels. Using the unpainted back.
Semitransportable my plan is to join a hobby exhibition in October.

Testing with doing a single pass of 1 mm depth to avoid accuracy becoming a problem . The bit seems to handle it; being such a soft material.

Looks like accuracy is good enough between 2 panels.

Kim,
I’m very surprised that you didn’t break a lot of router bits. In my opinion, the MDF (Medium Density Fiberboard) that I’ve used in this country for various projects is very hard; way too hard to cut with a 0.7mm router bit in a hand held Dremel tool. I suggest that you seriously consider using 1/2 inch thick or 1 inch thick Polyisocyanurate rigid thermal insulation board. It’s also referred to as PIR, polyiso, or ISO. It is much much lighter weight than MDF and easier to cut. You can push a nail through polyiso using just pressure from your thumb. Can’t do this with MDF. It’s hard to drive a nail through MDF with a hammer. I know from personal experience that routing a 0.7mm wide slot in polyiso is easy with a Dremel. Some polyiso board is available with a tough smooth face which would be suitable for magracing track.
The board in your last photo looks like it is some kind of foam board. Perhaps it's polyiso board. It doesn't look like what we call MDF in the USA.

Interesting to hear Ned. The Mdf I got are for paneling walls. They are only 11mm thick and fairly soft. I used one ball-bit for all 6 panels. They are also the cheapest pr m2 I can get at 150kr (15$ pr. 2x8.) 600x2400mm. The PU board are 5 times the price. It works good on my Maslow-CNC.

Magwire hotglued in place on all parts.
Some adjustments at the joints to come. But alignment is great.
