I need to thread a 2/56 thread on a 1/8" square part. My chuck will not close tight enough. I do not have collets at this time. I think I can accomplish this with a shop made fixture. Part is 1/8" square and 2-1/4" long. I will mill a slot 0.0620 deep and 0.125 wide in steel 1/4" x 1/2" and 5"...

I bought a Shars digital scale for the tailstock. This is stainless steel and glass 4" . The scale is too long and I would like to cut it to fit. The Igauging junk is aluminum and can be cut. I tried to contact Shars, so far no luck. If left long it may get in the way of the tailstock...

I have a drawing of a simple safety valve that I plan to make. The valve is spring loaded and variable pop off. Can the valve be tested at first with compressed air? Pop off is 30 lbs. pressure. Every valve I have searched for is not variable and starts at 50 lbs. pressure. I would like to...

I'm working on a tractor with plans from Rudy K. The boiler has tested good and now I'm making the gears. So far all the gears I made except for the pinion gears that mesh with 120 tooth bull gears. I have made them but the gears do not look correct and do not mesh well. I ordered a ser of 48 DP...

I am building Rudy K's Case tractor. Finally made a good boiler and now will try making gears. I think I'll be okay with the spur gears but the steering pinion gear has me stumped. I have gear cutters for the spur gears. Pinion has 16 teeth, blank diameter is 0.375 All gears are 48 pitch. Seems...

I have 1/8 x1/4" knurled solid copper rivets. I would like to use these to locate the front and back heads of a 1-1/2" diameter copper boiler. I am thinking 3 rivets 120 ° apart . The flanges will be hard soldered . I plan to flux the front and backheads , then drill the rivet holes and flux...

I am needing gear cutters with 48 pitch. Buying them is out of the question, would need to take out a mortgage to pay for them. Tried to buy the 9 gears I need, average cost $60.00 , more than I will pay. I found metric gear cutters that may be close enough, 55 m . Will the metric cutters be...

I bought a set of these scales, 6" , 12" and 24" aluminum rails. Only one of the displays works.The other two jump all over the place. I know if the rail is installed backwards this will happen. The display jumps even with no rails installed. These are the newer type that do not use a battery...

I am hard soldering a small boiler that will run at 30 lbs PSI . It will test at 60 lbs PSI. The front head is leaking at at least two spots. I cannot remove the head to re- flux because the copper rod stay is in . I would probably destroy the front head if I tried to remove it. The boiler is...

I recently installed new I gauging DRO's on the lathe and mill. The lathe went without a hitch the 24" scale was used on the X axis. The Z axis already had the scale installed. The mill had the Z axis already installed. I then installed the X axis first. The display was all over the place. I...

I recently was given a set of left hand drills. Which is the correct rotation , clockwise or counterclockwise? thanks mike

I am stumped trying to figure out how to remove the front panel on my lathe. Manual is no help. I have a short in the switch box and need to get to the wiring. I can see the quick change knobs have set screws, two each opposite each other. The start, forward and reverse and the red paddle switch...

My mill has an R-8 spindle. Yesterday I had trouble removing an end mill holder. Tried tapping the bolt with a dead blow hammer as I usually do. After about 6 or 7 blows I went and got an 8lb sledge hammer. I gently tapped the bolt and the holder dropped down. I assumed the problem was with the...

I am making a rear mounted tool post. I will have to bore holes in the carriage for 1/4-20 cap screws. I am wondering if cobalt drills or even HSS drills will work. Also , will HSS endmills work for a counterbore. Only 4 holes are needed. I will start with #6 drill and try to tap the hole. mike

Today I broke the screw that locks the saddle to the bed. The lathe is 10x22 G0602 .The screw is probably cross threaded. I'm afraid I'll have to remove the clamp to back out the screw. The top of the screw is broken about 1/8" below the saddle. I am not sure how to remove the saddle clamp. I...

I have Kozo's A-3 Switcher but cannot read all of the dimensions for the steam dome base. This on page 135 that is the fold out page. The steam dome base is in the crease and some of the dimensions are obliterated. Could someone post the image or even a sketch for me. I built the locomotive...

I always had problems re-using a partial tube of super glue . By accident I discovered a remedy. After squeezing out some glue I remove the nozzle. Then blow the nozzle out into a waste can or rag with compressed air. This clears the nozzle, then replace it and the cap too. Now I get to use...

I am making the Grasshopper engine. The drawings have unusual symbols that at first thought were sections or details. They are letters, SC,P,B etc. I tried googling "machine drawings" but could not find any info like these symbols. One particular symbol "B" is shown at the crankshaft where the...

Tim. A fellow by the name of Don Conner apparently was banned without ever posting. I think he said he just joined lately. He asked for help on a another machist forum, 7x12 or maybe 10x22. Don't recall as I am a member of both. Could you look into this , probably just a mistake. mike
