"One Perfect Part at a Time"

Miller Time

I got the CNC mill to cut the entire loco driver last night. The rough cut looked great. I included a finish pass in the code but using the same flat 1/8″ mill bit. Not so good there. Not yet ready for prime time. I also need to buy some solid wood for test blocks. I have been using multi-layer exterior plywood which is good for seeing the depth of each pass, but it splinters too easily.

I would also love to try wax. I have a sample. I may order a larger block and cut it into layers. Better… Continue reading

Wheelin’

Last night I had time to sit at my computer and work with Rhinoceros and RhinoCAM. Weird names but Rhino is a 3-D CAD program and the other converts drawings to CNC code.

Many months ago I designed a perfect drawing of the A3 locomotive driver and is one of the “driving” reasons for me to set the Micro CNC mill into operation. I ran my first output code on a wood block last Sunday and it was a disaster! The mill ran fine but the cutting was awful.

I ran the compiler again last night and produced another machine code… Continue reading

CNC Mill Backboard Installed

I got the backboard installed today. The afternoon was bright and sunny and the temp was cool. Somewhere in the 80’s. Just right for working in the shop.

CNC Backboard

The white material is available a Lowe’s. It seems to me mostly a plastic but somewhat like Linoleum. I was able to cut it with large sheet metal shears. It is attached with liquid nails. The corners are caulked. The material has a pebbly but shiny surface.

In the store Lowe’s built a booth using this material. It is where they wet cut ceramic floor tiles. It is holding up very well… Continue reading

CNC Running Again

I spent most of the late morning and early afternoon today getting the bits and pieces working again for the Taig Micro-Mill CNC setup. The configuration layout has changed since I built a new bench in a new location in the workshop. I also fiddled quite a bit with the electrical and software set-up. It is at a point where it can again do some CNC work.

The Taig Micro-Mill is still fine shape after it’s leap to the floor in the “Great Wreck (GW)”. I have the new ER 16 spindle on it now. This is a micro-mill and… Continue reading

Benched Myself

New Bench under construction

This is the project I have been working on all day. On Labor Day I was laboring my… um… you know, off! I also pulled in the power outlets below the circuit box and the one to the far right. The duplex outlets are fed with 220 volts split to each side with GFI outlets for each phase. This is in the garage so GFI is code. The outlet to the far right is 220 volts with a special plug. Its for my new saw, but I also have a special plan for Christmas lights this year. More on that… Continue reading
