    reamed hole vs. drill rod size

    Yes, I plan to silver solder the stem to the valve head. I have never done this before but I think it will come out well.

    reamed hole vs. drill rod size

    Hi all, thank you for all of the professional answers to my post. I think I will proceed as follows. Since it is critical that the intake valve stem be a tight sliding fit with the valve cage I am going to try 5/32 drill rod for the stem and a 5/32 reamed hole in the valve guide. I have some...

    reamed hole vs. drill rod size

    Hi, I am attempting to fit a 5/32 1018 valve stem into a 5/32 reamed hole in a bronze valve cage. No go, so I have to adjust some thing. I would like a tight sliding fit for the engine that I am building (Jan Ridders Scuderi cycle engine). It is important that this fit is tight as this...

    Mixing lead and silver solders?

    HI, I assembled some small fittings using 50/50 soft solder. This turned out to be not strong enough and the parts failed (came apart). I plan to use silver solder next, but these small parts are still tinned from the lead solder. It is not possible to remove this tinning without making new...

    Upon further scrutiny I think that is exactly what happened. Thanks for the replys, John.

    help identifying aluminum alloy

    It is not a peel-off piece of plastic. The pattern also has a very noticeable texture to it.

    help identifying aluminum alloy

    I bought this piece of 1/2" aluminum plate on eBay. It has this pattern on one side, and the other side seems to be just a mill finish. Does anyone know what this pattern means? Thanks, John.

    How to use a Conical Edge Finder

    I 'm sure my post wasn't very clear, and you are absolutely correct. What I was trying to say was if the conical side goes into the hole on center while the spindle is turning, and any down pressure is supplied, it will cause the conical part to stop spinning and ruin the spring. John

    How to use a Conical Edge Finder

    This is probably obvious, but never let the conical point touch the part while it is centered in a hole and the spindle is turning. The point will spin and ruin the spring inside of the tool. First hand experience. John

    How to attach a sight glass?

    Does anyone know where I can find a 1 1/2 inch clear glass disk? All I can find are disks that are textured on one side. Thanks, John.

    How to attach a sight glass?

    Thanks for the reply Peter, For what it's worth, I planned to glue the glass to the outside of the ring after it was soldered. Also, I'm not sure what a PCD is. Thanks again, John

    How to attach a sight glass?

    Hi, I am putting together a brass gas tank that is 1 1/2 inches in diameter. I would like to make one end out of glass. I am wondering what would be the best way to glue the glass to a brass ring that would be soldered to the tank end. I was thinking of silicone, but I don't know if it would...

    Use loctite glue

    I have a quick question concerning removing a loctited part with heat. After heating to the proper temperature, is the joint unglued forever, or will the loctite bond again after the parts cool? Thanks, John.
