Occasionally my expertise as an engineer carries over into the Baubilt world. Here is one such case. If you need to make fussy little shafts or brackets for some DIY project like a light fixture or a toilet paper holder, consider using the Misumi service. Misumi is a Japanese company that has a huge collection of semi-custom parts (hundreds of categories really) that are made to order using your uniquely specified parameters. For example, let’s say you need a stainless-steel rod 8mm in diameter and 96mm long for some perfect door pull you are designing. You can order that part from Misumi and it will be made to order on a computer-controlled machine tool (in Japan) and shipped directly to you…for remarkably short money.
Here are some parts I had made for use with the Ponoko parts described elsewhere. I think I had 10 sets made, and have already used 7 of the sets by now. My recollection is that these parts were $5-15 each, which is a screaming deal for a custom machined part. The trick of course is that these aren’t really custom; they are semi-custom parts that are made to order with your pre-specified dimensions.
Here is a Misumi page showing a “shaft support”…could be a towel rod support, no?
