In this instructable, I will go through the fabrication of frame sliders for a motorcycle. I have chosen, as an example, a Ducati Panigale.

In the event of a crash, frame sliders help to protect your bike against excessive damage. They space the body off of the pavement, thereby protecting portions of the bike from harm. We will fabricate these out of Delrin, a Polyoxymethylene plastic that takes abrasion very well. You may use any similar material.

TOOLS:

- Bridgeport, Jet, or comparable metal lathe
- Fine grit sandpaper

MATERIALS:

- Delrin
- Duct tape
- Ducati Panigale

Step 1: Measure and plan

Use a ruler to determine how far your wheel sliders will have to protrude in order to protect your bodywork. This can be eyeballed and erring on the longer side is usually a safe bet. Also measure the inner diameter of the axle.

This is very important. You'll want to use some calipers to get as exact a measurement as you can to ensure a good fit.

You'll want to have an inner sleeve that goes into the axle about an inch or so to give the sliders some structural rigidity. Factor that into your cutting plan.

Step 2: Mount your material

Once you have your measurements all squared away, grab your materials. Delrin is a good choice because it's quite strong and machines very nicely. Here, we have 2-inch stock.

Use some duct tape to protect the base of your work and to provide some grip on the slick surface.

Go ahead and chuck up your piece in a 3 or 4 jaw chuck.

Make sure that you have enough material to work with. For instance, if the overall length of your finished piece will be 3 inches, make sure the piece you use is at least 5 or 6 inches to allow for waste material to fit within the chuck.
That is a very nice bike

It would probably be better and safer to get a HSS tool blank and grind to rounded or chamfered profile
File works and is quick but if repeatability is required a form cutter would be better
Could probably use a damaged/blunt circular saw blade although it's a bit thin
