Tooling

Applications

• Secure tubes for mitering
• Fix a frame onto a milling table for further machine work
• Help prevent tubes from getting damaged

If used for a different application, then the user assumes all risks and no refunds or returns are allowed

Material

• 6061 aluminum

Assembly

• Consists of two pieces:
  • One side accommodates two M5 clamping screws (included)
  • The other side is threaded to accept the clamping screws

Bore

• Available in wide variety of sizes:
  • Choose the correct bore based on the OD of the tube you want to secure
  • Choose the outside dimensions based on the application you will be using it for

Quantity Discounts

• Buy 10+ tube blocks and receive a 10% discount

General Information

• Paragon Machine Works took over the supply and manufacturing of Anvil Bike’s dummy axles in October 2019
• All Anvil dummy axles are guaranteed to work with the wide variety of Anvil tooling
• We do not guarantee that they will work with products manufactured by other companies
• Dummy axles that DO have "Exact" in their product title are on-size between faces; for example, a 110 mm dummy axle will measure 110 mm between the faces
• Dummy axles that DO NOT have "Exact" in their product title are oversize to help compensate for distortion after welding; for example, a 135 mm dummy axle will measure 137 mm between the faces

General Information

• Introduces argon into the frame
• Absorbs heat from the weld to reduce distortion
  • Distortion will not be completely eliminated
  • Results will vary based on tubing diameters, wall thicknesses, and personal welding styles
• In our shop tests, we were able to install a threaded bottom bracket assembly with no post-weld machining

Assembly Components

All metal-to-metal interfaces are bronze to stainless steel

• These two metals have a very low coefficient of friction with each other, making sticking, binding, or galling very unlikely

Center:  1 each

• C-630 bronze

Cones:  1 each threaded and unthreaded

• 303 stainless steel
• The center expands with two cones to fit with minimal clearance on the interior diameter of the bottom bracket shell
• One cone butts against the draw bolt and the other is threaded female 1/4" NPT for the argon connection

Thru Bolt:  1 each

• C-630 bronze
• Drilled to accept argon from the threaded cone
• Has an internal hexagon to accept both a 5/16" and 8 mm Allen wrench

Washers:  2 each

• 303 stainless steel
• Plug each end of the bottom bracket shell

Hex Nuts:  2 each

• Zinc-plated steel
• M20 x 1.5
• Secures the washer

Steps for Use

1) After the frame has been tacked, remove from the fixture

2) Insert the bronze expanding sleeve into the bottom bracket shell

3) The sleeve must be compressed slightly to get it in the shell

4) Place both cones in the sleeve

5) Insert bronze draw bolt through one cone and thread it into the cone on the opposite side

6) Using the 8 mm internal hexagon in the bolt, tighten the bolt which will expand the sleeve

7) Install both washers

8) Install mating nuts
