Below we can see the standard Lugger engine mounting bracket split between its top fixing bolts. I have seen this issue so many times where the backward thrust from the engine head finds the weakness in the open grain of the iroko and twists the top section resulting in it splitting between the 2 bolts. You will again note the issue with splitting within the open grain structure of Iroko with the Dabber Thwart/Step.
This image shows an engine mounting bracket for a Lugger having been made up out of 2 x 22mm laminations, in effect 2 slices bonded together and increasing the thickness to 42mm rather than the 30mm ish of Drascombe normal spec. This gives extra strength from the thickness and tackles the splitting issue.
The important point to notice and it is very evident that the opposing grains of the 2 sections create this structure and its strength, there is no through grain for it to split along, this again is normally between the 2 top bolts. This results in a better product that will last longer and be stronger. Revision and updating of these parts is important as materials and bonding agents, along with certain processes, have improved so much that the benefit of revision and application to older parts is huge.
These Engine mounting plate are now available both as standard and also as Laminated. Please check out the product page for more info or get in touch.
