Hi Chris,

Nice bumper guards. Do you have the weight of a single bumper guard?

Can you post a photo of the interior section?

Thanks,

[chris_seven]

Bert - 340 grams - just under 12 ounces (1/3 of steel parts as all thicknesses are as per standard)

Upper mounting



Lower mounting



As I said they were pressed in two halves using a Dual Form and then welded.

I will take some photographs of the lacquered parts after the weekend as I will be at the Race Retro show or a couple of days.

Hey Chris, they look great and I'm really interested, but I'm not sure which version to get... what is an 'adhesion promoter' and why might I want/need that?

[chris_seven]

Laquer doesn't stick well to either polished Aluminium or Chrome and UPol have developed a material that has better adhesion than lacquer but is quite soft.

According to our paint supplier it is being used on a large number of classic bikes and works quite well.

The general idea is that the 'adhesion promoter' sticks to the metal and the lacquer sticks to the 'tie coat' and means that the lacquer is less likely to peel. Both materials are said to be completely clear.

If you don't lacquer the Aluminium it will tarnish and dull and will need to be cleaned with a metal polish such as Mothers on a regular basis.

I will try to anodise these parts but I suspect that this process will pick out the weld and will not enhance appearance. I will know within about 10 days but I am not holding my breath.

To press these part from one-piece so that they could be anodised would have been too expensive even using some of the vacuum formed Super Plastic Alloys would have cost a few thousand dollars in tooling.

We made the Dual FormTools at a relatively low cost as we don't expect to sell thousands of these parts.

Thanks,
