Here we go again . . . MK4

Other jobs around the house mean slow progress in the build. I've managed to get the second beam machined.





Drilled and tapped the M5 holes. I bought this spiral fluted tap which has different colour bands for different materials. I thought I'd try this yellow one (for steel) and it works really well.


I've sprayed them with a light dusting of zinc galvanising spray (screwfix) just to keep the rust off and make them look presentable. I've found this sticks well to metal and resists scratching. (Note Spitfire languishing in the background )




Next job is to put it all together, shimming if required, then set it aside. Then move onto making parts for the bed.
