    Lobo 2 and 3 cylinder build.

    I can't resist adapting. I started Gails Lobo2 and thought - how about 3 cylinders as well. So - here are the cases and cylinders for a twin and triple. The trip will have either 3 carburettors ala "Sukuki trip" or car/marine type inlet maniflod. Maybe 3 expansiontype chambers for the exhaust as...

    Simple ?? Engines and not so simple

    Last year a young person asked me if he could make a simple engine with only hand tools. Answer, course you can. I had a copy of a design years ago but lost it. Drew another one based on K&S brass tubing. Made one up, it worked and he is now making one. I was thinking later, "How far can you...

    Need help to cut Honeycomb Ceramic Tile

    If it was me I would use my glass/tile saw. Warrior have them for between 100 and 150 $. Another one to try would be Stone disc in an angle grinder. I used this method to cut ceramic tiles for my wifes mosaics. The glass/tile saw makes it SO much easier. The one I have is a GMC LSTSAW. cost me...

    Glass wobbler

    It took roughly 12 hours to get to 840c. The main problem is to dry the moulds out. Heat to fast and they WILL crack. For the larger moulds I re-inforce them with fibreglass tape. Water boils off at 100c, But chemically combined water doesn't come out until roughly 600. Annealing took roughly...

    Glass wobbler

    Steaming the wax out of the mould using the trusty Steam Duck. I use this for small moulds, for larger ones I have converted a Pressure cooker for steam delivery. Somtimes I use a Heat gun, but this can cause cracking of the mould. To get the last vestiges of wax out I will rinse the mould with...

    Glass wobbler

    Ok, you have me interested. As the philosopher "Clarksonius" was fond of saying, "How hard can it be". It will be a simple wobbler, roughly 16mm bore, 20 mm stroke. Lead Crystal except for the piston and rod and the mains shaft. Piston will most likely be Teflon (It will be running in a glass...
