Holes in Bar Stock

[allioupe]

I'm looking to make a custom motor mount for small airplane electric motors. The ones that came with the motors are flimsy and cheap. To save on costs I chose standard 1inch by 2mm (I think) aluminum bar stock you can get al the local big box store. However, I am not accurate enough to make the holes with my press. I drew up a design (attached) for CNCing and I was quoted about $275 from the automatic analyzer. I know someone somewhere can pop these things out by the dozens..

it's 1inch x 2 inches long and I have the centers of the circles and the countersink measurements.

Anyone know a quick yet cheap way to produce. Heck I may even start selling these things as there is demand for them..

You would be best to have the material cut to size.

Then have a drill jig made then you can make them yourself on a drill press

CNC is one option if'n you have CNC equipment, but to get it done by someone else means you are paying them the profits you would like to make.

Get a drill jig made as suggested, and you can drill all day long on your drill press, with parts identical each time, and the profits stay in your pocket.

If you are using the correct size bar stock to start with, then the part is extremly simple. Have a local machine shop mill the part for you. Cycle time on a part like that should be under 3minutes apart. For one or two peices you should be looking at around $40 a part. But if you ever decieded to sell these parts and order a larger quanity around 25 or more. The cost per part should be under $10.

1" x 2mm bar stock??? If you are working in metric it may be to your advantage to take a course in metric. You could save yourselves a lot of trouble further down into your project. No offense - just advise.

Very easy part to cut on a cnc or manual. Not sure if this is suppose to be like this or not, but two of your counter sinks look to be off.

Have a laser cutter shop cut them.

5' X 10' sheet of 14 ga, cut as many as can get out of it (Holes included) 3000+ pcs.
You can do the countersinking in your drill press with a good tool.
Should be in the $.15 each range from laser guy.
