Well I have taken the plunge and purchased a universal riveting tool from G W Models uk. Supplied with 2x punches and 3x anvils allowing rivets to be made in 2, 4 and 7mm scale. The two adjustable tables give accurate movement of the work piece, for every one turn of the wheels giving 1mm of travel and each division giving 0.05mm (.002”). The tools allow both half etched rivets to be formed or for scratch building a full rivet. Looking forward to using it on the Crosti 9F kit and the Bulldog. I’ve been told that he’s running out of components due to some world crisis going on ??? So if your in the market for one, get your order in ASAP. No links with the company, just very impressed with the quality of the build for the price.
