My main business is building custom bicycle frames. But since I design and build most of my own tools, I offer some for sale to other builders.

If you know what you're looking for, go to the Purchase Tools list to make a purchase using a credit card or PayPal. If you can't find what you're looking for, please check Custom Work and/or contact me. For international orders or other means of payment, contact me.

Pictured below are just a few of the frame building tools I offer. Please browse the following photos and descriptions to learn more.

NEW 30 x 17 Oval Tubing Blocks, 26 x 17 Oval Tubing Blocks, 33.5 x 15.5 Oval Tubing Blocks and 28 x 19 Oval Tubing Blocks Designed for machine mitering, also useful for general workholding. Machined to exacting tolerances from 6061 aluminum and supplied with two M6 clamp bolts. Since there's no mathematical definition of "oval", these blocks are made with elliptical cutouts. Outside dimensions are 2" in the narrow oval dimensions and about 2" in the long oval dimension, the latter being dependent on the exact dimensions of your chainstay or fork blade. 30 x 17 oval chainstays are also sometimes known as "24mm oval" and 26 x 17 oval chainstays are sometimes known as "22.2mm oval". 33.5 x 15.5 oval chainstays are formed from 25.4mm tubes and are sold by Nova Cycles as oversize 29er S-bend. 28 x 19 fork blades are often referred to as "Continental Oval." Blocks are 1" in thickness. Click for pricing and ordering.


NEW 30 x 17, 26 x 17, and 33.5 x 15.5 Oval Clamp Blocks: CNC machined steel blocks are intended for use with my seatstay/chainstay mitering jig (further down this page) and are also useful for general workholding with oval chainstays. Sold as two complete blocks (four "halves") as shown in the photo. Click for pricing and ordering.

NEW Front Derailleur Boss Locating Jig: This is a huge time-saver. Modern drivetrains require the FD boss accurately placed in accordance with their specs. This steel and aluminum jig places a front derailleur boss 9mm inboard of the BB face and 8.7mm forward of the seat tube centerline, while holding the boss parallel to the seat tube for brazing. Reversible plate allows for 1-1/8" and 1-1/4" seat tubes. Rod is 10mm diameter to match most front derailleurs. Always check the manufacturer's specs for proper FD boss location. Spring clamp not included. Most FD bosses will require some cold setting or filing to achieve the correct location, and this tools also acts as a quick gauge to determine whether the positioning is correct.

NEW Braze-On Locating Jig: Locates and aligns cable stops and housing guides. Aluminum blocks clamp securely to the tube with thumbscrews. Steel bar locates in slot, so turning the bar around without unclamping the blocks aligns stops at both ends of a tube. Steel bar has one wedge and one channel to work with a variety of braze-ons. Fits tubes from 7/8" to 1-1/2" diameter. Click for pricing and ordering.
