    Thanks BlueJets, on the fine sand part, Growing up my parents owned a comercial pottery which sold plates bowls etc to Parks Belk and other stores. when they retired there were sacks of "silica sand" that was such a fine mesh you were to always wear a respirator when messing with it. back...

    Building a twin cylinder inline i.c. engine.

    Brian, i should be able to. assuming my idea works. a diamond drag bit is nothign more than a diamond tiped scribing tool mainly used for scratch engraving. i have a small cnc 3018 that i use that drag bit for some engraving. so really all i should have to do is draw a 1.1" in diameter...

    still learning, what causes this texture

    still learning casting and am getting usable parts but wanted to know why the rough texture? sand to wet maybe? im using a 30% bentonite from well drillers mud and 70% play sand. all sifted and hand mulled (that takes for ever and gives your hands a real good work out) this was just scrap...

    Size standards for homemade engines !!?

    last couple 4 strokes i did were 7/8 bore and 3/4 bore. one thing i was glad about is the largest collet i had was 7/8 and i prefer holding the piston in a collet if i can to do all the underneath the piston work. yeah, couldve used a vise or vise/vblock etc but the collet is so much easier...

    Vertical 4 cycle engine from recycled parts

    brass wood screws on the 4 corners of the battery cover plate? or maybe some studs and wing nuts or similar on the 4 corners to make it easier to access? on the fuel line, do you think it will get hot enough to vaporize the fuel in the line being that close to the fins?

    magnum 120 FS repairs

    the pouring wax into the hole and pounding it out almost sounds like the old trick of using plain white sandwich bread and stuffing it in a pilot bearing hole to get the the pilot bearing out of a truck when replacing the clutch and such. i couldnt believe that actually works (and it did on an...

    Question regarding hardening of 01 steel

    you can also dig up some yard clay and make a putty out of it and dab around the part you dont want to harden. but if the part is short the heat will still travel and when quinched will still harden partially. also watch for warpage

    My new project ...Small diesel engine .

    the main stand, pillar or "block" of the engine (not sure which of the 3 best describe it). Do you plan on casting that or barstock? im intersted in seeing how you handle machining that if done from barstock. im also interested in seeing how you cast it if you go that route

    My next build--A cross beam vacuum engine

    Brian, i wont mention this again as im sure you are tired of me saying this. but you laped in your piston to the cyliner with 600 grit (while cold). i believe that was how you did your flame eater engine as well and you couldnt get it to run. what i found was do not lap the piston to the...
