I like my early 40's Allis Chalmers B with a finish mower. Used it for twelveyears and literally did nothing but add oil, gas and sharpen the blades a coupletimes. You can get them from about $250 to a grand. New machines are hinky when it comes to the carbs, sitting, and auto gas, especiallywith ethanol. Just another perspective!

Hi all,A long time since I posted anything. Yesterday morning on pre-flight I noticed that the lashings on one of my bungees was slipping. Its time to change the bungees anyway, and it seems like a good time to convert to spring struts. I have Hans VanderVorts design in hand, and I've also looked at William Wynn external tube design. Those of you already using these designs, are you happy with the spring that ACS sells, or did you use something from McMaster Carr that works as well? I've seen several Piets with the exposed spring design, but haven't seen one like the Wynn design, though it looks like it would be easier to convert using pieces from my existing gear. Your thoughts welcome!Ben CharvetNX866BC, 326 hrs and holding for upgrades-- Ben Charvet, PharmDStaff PharmacistParrish Medical center________________________________________________________________________________Subject: Pietenpol-List: Re: Pietenpol-List Digest: 3 Msgs - 01/18/17

Jerry,You might contact Bob Dewenter in OH, who has a spreadsheet that will calculateweight & balance. Since we don't have a photo of your project, it's difficult to identify what allyou'll need to input into the spreadsheet. That said, the items will includeall of the existing weights, and dimensions along with the weight of the ModelA/B, engine mount, and associated cooling equipment. The spreadsheet may be used in an interesting manner, where you can actually useit to calculate the CG by entering the position of the engine & cooling items,and modifying those locations. From this info, you can construct the enginemounting system to place the CG within limits.Bob has a full set of instructions as to how to use the spreadsheet, and it willtake some working with it to understand what to do, and how to do it, but itwill eliminate all of the hand calculations to answer the questions you have- at least regarding W&B.Bob's email is rdewenter (at) woh.rr.com (Forgive me if this results in a floodof emails, Bob!)Best of luck in your build - and please post pics!--------Tom KreinerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Pietenpol-List Digest: 3 Msgs - 01/18/17
