John, Would a vacuum cleaner nozzel placed near the cut to suck away the dust have worked? I wouldn't through that shirt in with the other laundry. Might get that stuff all over the other laundry or were just telling porkies? :lol: Bernd |
| Dean W:
Nice job on the valve, John. I liked the way the fasteners came out, too. They look like they were crafted, rather than just cookie cutter punch outs. I think they will look good in place. Dean |

Bernd, would you like a vacuum droning away in your ear for about hour and a half while you are trying to concentrate on something. No thanks, and besides, once I wrapped up the paper towelling, it was basically all gone. No joking about the t-shirt, but over here we have things like washing machines and powder to get things clean, we gave up pounding laundry on rocks at the side of the stream a few centuries ago.

All looks brilliant John. Don't think there's any need for great tension in the springs either. Just enough to keep it flat against the port face. |
| Bogstandard:
You are quite correct Nick, the springs are only there to keep the block in position, the vacuum produced by the engine will keep the block sealed against the face. This is the quandry, too much spring pressure and there will be too much friction produced and the block will wear away in no time. The springs are a rather heavyweight about 3" long, maybe a bit more, and 1/4" diameter, but I do have an elegant looking redesign if these are just too strong in the beginning. This engine will of course run with all these supplied bits in place, without any mods being done, but how long would it last?. I always look for improvements, not for the sake of it, but to produce a more efficient design by well known methods. Most engines will run quite merrily without all the mods, ballraces et al, but when you do fit them, they make a very significant improvement not only in running quality, but to engine longevity.
