    How to store etching acid?

    Average Joe buys the clear PVC cement and calls it good. But, if you look in the section where the PVC cement is sold you will also fins PVC cleaner, and you will find PVC Primer. The best joints are made by cleaner, primer, then cement. You can often get away without the whole process, but sometimes you won't. Not saying you're not above average . You just may not have known about the whole process. No one knows everything about everything.

    Bluetooth headset interference

    Glen, I think you are right about power tool interference to Bluetooth being too small a problem for manufacturers to worry about. As it is the level of background "noise" increases all the time. The FCC is charged with dealing with radio interference, but is so strapped with bigger problems that this problem will probably never see any attention. The switching power supplies in LED light bulbs and other consumer electronics are posing quite a problem for ham radio (Amateur Radio). Manufacturers seem to pay little attention to complying with FCC regulations, and the FCC is so under funded that they cannot deal with it all. I'm no expert at radio interference so don't know if there is any practical way to deal with it in regards to Bluetooth. The size of Bluetooth devices makes conventional avenues such as shielded cables and wrapping cables through ferrites impossible (at least at my skill level). Alan

    Bluetooth headset interference

    The first radio transmitters were arc based. And I think that I read that they are now banned due to the wide splatter of frequencies they output (there was no one else to share the spectrum of radio frequencies with back in those pioneering days). Every time you pull the switch you are creating a local radio transmitter. I don't think there is any practical way to prevent the Bluetooth interference. Alan -- K1ALN

    A Bit of something

    I would not go anywhere near a primer pocket with a center drill. Primer pocket uniforming tools come sized specifically for primer pockets (large and small), are flat bottomed, and have a shoulder to control the depth of cut.

    I use Coors Light as my quenching medium...

    Ah, you bring back memories of the sixth grade and the hiss and steam when boys would try to quench the steam radiator in the bathroom on a cold New England day. While I never contributed to the effort the attempts of others made even a brief excursion into the bathroom extremely unpleasant.

    Maybe Some Kind of Sharpening Block ?

    Thanks everyone for the replies. I've scrapped my plans for a thick bolster plate and will oil this well and put it with the "might be useful later" items. As to being less flat for the cleaning I might have chosen electrolysis if I had any inkling of what the block was, but as I said above there was so much rust on it that the cross hatch was invisible (which made it not flat in and of itself). I have carbide scrapers and a small surface plate in pristine condition, but restoring the lapping plate has too little reward at the present.
  9. I stopped at yard sale this past weekend and as I was leaving I explained that I was learning black smithing; and asked if there where any heavy pieces of metal around. The home owner said "just a minute" and disappeared around the corner of the house. He returned with a steel block and said to take it gratis as he didn't want to take it south with him. The block measures 4-3/4 x 7-3/4 inches and had a moderate coating of rust. At that time I couldn't see any printing or cross hatch pattern. But when I went over the block with a zirconia flap disc I could see the letter C on the sides of one half of the block and the letter F on the faces of the other half of the block. Turns out he thing cleaned up really well. The disc removed the rust and revealed the cross hatch pattern on the top. The thing is hard enough to skate a good file. I going to venture a guess that perhaps the block was used with some kind of abrasive slurry to sharpen something. Does anyone know what this is and was used for?

    Ticks and Lyme Disease

    Here is a link to a very informative article about testing for Lyme disease and its possible relationship to other diseases: http://boston.cbslocal.com/2017/09/29/nightside-a-new-perspective-on-lyme-disease/?e=tteo5fmMDwDwSA&utm_source=email&utm_medium=email&utm_content=11385&utm_campaign=daily-news-headlines-recommended--9 Click the right pointing arrow in the circle, located on the bottom left of the image to start the program.
  11. I found this bar/block of steel 3" x 3-1/2" x 13 inches at a scrap yard yesterday and couldn't resist at 20 cents per pound. I have not tried any spark test on it but as you can see in the photo it has some numbers written on it, a lot probably relating to some job. I can make out AMS 5643 and H1075 . Researching on line these leads to information on heat treating 17-4 stainless (one hour at 900 degree F and air cool yields Rockwell C 44). The steel is magnetic, but noticeably less so that the jaws of the vise to the left. It was sold to me as generic steel rather than stainless which would have been five times more money. It would be a rare thing for this yard to miss identify some steel. I think it looks like a vertical portable anvil once a base is fabricated Any thoughts?

    Hex Forge - idea for your review

    Mikey, The Ceramic Shop dot com in Norristown, PA has the 4" x 6" kiln shelves. I just looked and their smallest is 2" x 6" Alan

    Hex Forge - idea for your review

    If you want to keep something off the floor of the forge there are all sorts of "kiln furniture" items available. such things as small cubes, triangles, short cylinders, as well as kiln shelves that are as small as 4" x 6". All of these would be low profile, and would be removable and re-position able. Alan

    Cleanup of Champion 400 Gearcase

    Here are a couple of photos showing the improvised bracket. The round rod shown is welded to the base plate and the jaw to the right and serves as a pivot point for the movable jaw to the left. Each jaw (cut from a segment of heavy wall tubing) has a rib (cut from the same tubing) on the inside. There is a sheet of thick cork gasket between the blower and clamp, and the two bolts draw the clamp together.

    Cleanup of Champion 400 Gearcase

    It will go faster if you physically remove as much grease as possible before you start with the solvent. I use cotton rags and something like a paint stirring paddle. For solvent I use undiluted orange oil cleaner, but kerosene or mineral spirits (paraffin or white spirits) will do the job although be less pleasant to work with. From what I've read you should not put grease back in there. It's too thick and will make the blower hard to crank. Oil is the preferred lube. Be very gentle with the fan its delicate. And watch for loose ball bearings! There are some comprehensive guides to a restoring Champion 400 available if you search. There are some YouTube videos also. If yours did not come with a stand feel free to contact me and I'll let you know how I built the bracket to hold the blower. Alan
