A previously unreleased rendered image produced from the new Bristol Bulldog Mk.II kit shows just how that Jupiter engine dominates the profile of this advanced fighter.
Although the Bulldog was from a relatively early era of aviation, it was very much the best of breed and just looked beautiful!
The latest in a long line of Workbench exclusives, this next selection of images feature the latest test frames produced from the new Bristol Bulldog Mk.II tooling, a kit which is expected to be with us before too long.
most issues highlighted rarely require wholesale design changes to be made, there are usually lots of smaller issues a designer will need to bring to the attention of the toolmaker, but in the case of the first round of frame review recommendations, how this rarely involves having to instruct the toolmaker to weld metal back into the tooling design, or for a designer to go back into his CAD to make significant alterations. Something like that really would be an unusually dramatic development for this stag
incredibly important at this stage of the development process is how completing numerous full and partial assemblies of the components received is essential. This is not only to check the accuracy of the tooling, but also how adjoining components interact with those which they will need to be connected to and if any gaps or misalignments are evident. Sometimes, the placement or manufacturing authenticity of assembly location points on the kit doesn’t translate as the designer had intended, something which will clearly need to be addressed

The EDM machining process is used because it supports the representation of particularly fine detail in a tooling and uses a method whereby copper electrode technology fires a high energy spark to selectively burn away metal from a steel tooling block. Once the electronic spark has done its work, it is stopped and dielectric fluid is allowed to rush into the new cavities, washing away any residual molten material and essentially curing the newly recessed detail in the tooling.
this process is typically carried out in stages and when done correctly, can be used to replicate even the most subtle of surfacing design detail within a new model kit’s tooling.
the initial replication of the wing fabric surfacing detail, he was confident it would be right in the end. That being said, his position doesn’t allow him to assume anything, so therefore he has to report all his concerns back to the toolmaker via his report
This next fascinating selection of images were supplied
to illustrate the issue he faced when assessing the Bulldog’s engine components and how it was crucial he impressed on the toolmaker just how crucial it was to ensure the correct orientation of the individual parts.
By the time he received the next round of test frames produced + further attention by the toolmaker to have reduced by around 2/3rds and how some of those might be as simple as asking the toolmaker to polish clear parts a little more vigorously than they had.
