Hi Phil, this will get you that collet. This comes from a five-year-old forum comment but the company the author refers to is still in business. They should have what you want.
MikeRe: Custom 1/8" Collet for Makita RT0701C Trim Router
Being very satisfied with the collets produced for us, I’d like to now share the information about the company that made them.
The company name is Elaire Corporation of Ohio, and the URL for their website is http://www.elairecorp.com
I dealt with Mark there, and he can be reached via the E-Mail address sales@elairecorp.com . Mark was fantastic during the entire process, responding quickly to my E-Mails, and keeping me updated as things progressed. Total turn around time for custom manufacturing of our collets once I committed to purchasing them was about a week. Pretty awesome for a custom run of only 16 pieces.
Mark said that he rounded our batch up to 25 total pieces, and would offer the remaining 9 pieces on their website, first come first served, for $19.75 each. If you contact him via the sales E-Mail above and mention that you heard about the custom 1/8" collets for the Makita RT0701C Trim Router on the Shapeoko forums, he will give you the lower $17.50 price break we got for the first group order. Awesome.
They accept payment via PayPal, which is convenient. Mention that you would like to pay via PayPal when you E-Mail your order, and they will send you a PayPal invoice for the number of collets plus shipping. The invoice simplifies payment and gives you something you can file for your records.
If you have other types of spindles out there that don’t offer a stock collet for 1/8" bits, definitely check Elaire Corporation’s web site to see if they already offer one for your model. For example, they already offer 1/8" collets for the DW660 trim routers. If you have some uncommon spindle that they don’t already have collets for, I definitely recommend that you contact them about making you a custom collet. In the case of our custom 1/8" collet for RT0701C, there was an initial set-up cost of $50 for two collets, with increasing price breaks at 10 and 100 pieces. Of course the cost to create a custom collet for your device will vary based on the size and complexity of the collet, but I’m certain their pricing will be competitive. And of course, their service is top notch.
Regarding the collets themselves, they are extremely well made. In the case of the custom 1/8" collet for the RT0701C, it showed between 2x and 10x less runout than using the stock 1/4" Makita collet with an 1/8" set-screw adaptor. Check out my mini review and runout tests earlier in this thread to see how I tested, and what the actual runout measurements were.
All in all, a fantastic experience. Thanks also to the Shapeoko members who participated in our group order. Your collets will go out tomorrow and hopefully will be humming away in your machines shortly thereafter.
If you have any further questions, please don’t hesitate to ask.
Peter.
Mike
