In USA NPT pipe threads are tapered inside and out, they are most common. I think BSP? are straight though. American pipe sizes can also be had in straight pipe. IIRC it is called NPS Everyone is right in this case due to differences over the globe :D

now you need to mount zipmax on a seat frame and not have to worry about kicking the pedals :D
-
cool, thanks
-
Neil, did you use the pipe as a "sawhorse" to rest the bar on or did you have the inside of the pipe even with and pointing at the bottom die with the long stock inside the pipe so it was somewhat contained to keep it straight?

$50-$200 Search manzel oiler on ebay for some ideas-look at completed listings

Have you got this fixed MacBruce?

More common to see them on old tractors. Some of them the shaft had a pulley to a belt and would spin and some had a lever that worked a ratchet inside to spin the shaft. It will put out drops of oil - that should be adjustable. It looks like the plunger in the front is to feed some oil before starting the equipment. Also looks like it may have run on the lever set up due to no pulley. Mine are set to put out one drop every 10 seconds or so so not much comes out if you try to test it. smith

I read his post differently and took "travel" to mean jaw travel because of doing hot work it needs to close quickly. It meaning the jaw. ;) I also would think that he is smart enough to know that 3 threads per inch does not equate to 1/4" screw advancement. Maybe he will chime in? At any rate you (KA) should look for something close to 2-3 threads per inch 1 3/4-2" dia.
-
Are you thinking the jaws close the exact same as the threads advance like a machine vice? Leg vice moves on a pivot and since the jaws are farther from the pivot than the screw they will move farther. My 7 1/2" vice with 2" dia thread with 2 threads per inch moves the jaw from closed to 11/16" open with one revolution of the screw. Not the 1/2" that your method of calculation would have given. Hope this helps with what you need. quibbling smith out

I bought a large 3 ph compressor (15 hp) years ago from a guy that was running it of a tractor like yours. Should work great. :D

Found this video of using a kiss block and it seemed appropriate for the thread:

I learned of "allowable stones" when a batch of coke came with river rocks in it. Several handfuls per bag. The only way they could get there would be to add on purpose so that was never purchased again.

Link here: http://www3.museumofmaking.org/dbtw-wpd/machine_video.htm this guy is amazing, he has a cute little "table top" bradley in his still pics. The little guy fits on a standard pallet and is maybe the nicest bradley on the planet.

Sounds easy. No reason to use pemalac if you dont use japanese brown stain the two go hand in hand. Give some more details.

I have heard the suppliers are allowed a certain percentage of "stones" by law and if they dont meet that amount they will add stones until they do- more coke to sell if it is cut with stones. :o

I get so tired of people whining about rebar. What type of rebar are you using- or do you know? Many types and qualities available- junk metal available for sidewalks is not the same as high strength or welding rebar that is much more controlled in its recipe. All of the info needed is on the bar- those letters and numbers are not random. smith out

What runs them? Air?

large diameter pulleys have more surface area to grip the belt. Does your hammer slip the belt or have a separate clutch?
-
Thank you!! I went and checked out your link Neil and that guy is amazing and his place is a must see!! Loved the baby bradley hammer, it looked almost like a table top hammer sitting next to the bigger one. Cleanest, nicest bradley hammers on the planet along with everything else there, WOW. Here is a link to one of the videos: http://www3.museumofmaking.org/dbtw-wpd/machine_video.htm

No grinder, sanding disk only, like said above 120 grit and then use the anvil, dont try to remove the pits. Hold the sanding disk as flat to the anvil as possible , do not tip it up and let the edge dig in!
