I think your soft tubing would be ideal. If I had some on hand it would have saved me time and trouble. I tried to bend a 90° bend with 7/32 copper pipe. Used a small tubing bender made for it. After kinking the pipe 3 times I annealed the pipe and still kinked it. Then filled the 10" long pipe...

I also have used alum. The first time I broke a 2/56 tap in a 6061 aluminum cylinder. I mixed alum and water and set the cylinder in the glass jar covered with alum. I checked the next day, tap was still visible with no apparent dilution . After 4 more tries in as many days I went online for...

I go about it the same way Cogsy does with one exception. I lay out the center, Then install a tool I made I call a "point". I locate the center, install a spotting drill. After the spotting drill I center drill. This is done on a DP or the mill. I install the work in the 4 jaw, bring the tail...

. Now that you have a precision level , read the instructions that came with it. The level has adjustments. You will find that this level is not comparable to a carpenters level. Much more sensitive. This level will indicate twist in the bed , if there is any. The level is place across the...

You can buy straight flute bits. These are made for brass and copper but are expensive. My grandfather had a set that I am sure he got from work. They look like chucking reamers. I did a search and found that Grainger has sets from 1/16" / 1/2" for only $718.00. There is info on you tube on...

I had a cousin who built either that engine or one that is similar. Mick was a machinist and had access to a local foundry. I believe he built his engine in 1962 . I have the South Bend project book. I only have built the simpler stuff, that engine is beyond my abilities. I know of no foundries...

I have the information I needed thanks to Crueby a member of another machinist forum. mike

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'll also add Practical Machinist but remember this forum is for professional machinists. Do not ever mention a Chinese made machine. Taiwan, Japan , any other country of origin is fine. There are many sub-forums that are for particular discussions. Logan, South Bend, and many other machines...

Small drills can be sharpened with a hand held tool that I made from the "Bedside Machinist" by Guy Latrobe. This tool is easily made . Intended to sharpen drills from 1/8" to # 60. This tool worked so well I made another to sharpen #1 drills to about # 40. I use a small diamond plate about...

My grandfather had a set of drills only used for brass. They were straight flutes ,no spiral. They are still available. Ohio drill. or something like that still supplies them. Try a search for drills for brass. mike

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...

Dave, I can't advise you on the torch, I bought a Victor torch myself. As far as reflecting the heat towards the boiler, you need refractory brick also known a s insulating brick. I also bought a 3lb container of refractory cement. You can use it to cement broken refractory bricks together or...

I bought a set of R-8 holders that included 3/16,3/8,1/2,5/8,and 3/4" diameters. I often use small endmills with shanks that are either 3/16" or 1/4" for 1/64 / 7/64 endmills. There are few sources for 1/4" diameter holders but after reading your reply I did find reasonably priced 1/4" and...

Your end mill has a 1/4" shank which is not common for the holders. Make a holder from scrap round 1018 or what ever you have . Bore the hole slightly less than .250. Then ream the hole to .251. Turn the outside of the blank to fit an endmill holder you do have, I used 3/4" because I rarely use...

Jim, I use SRA solder and flux. I have two different types, one for copper, brass and bronze. The other for steel and other ferros metals. They look the same, white borax type of flux. I don't know if your flux is similar to SRA products. The flux will help to keep the parts from oxidizing. Try...

Mapp gas in 16 oz. cylinders and small torch will not work on a 3" copper boiler. I use a Victor torch set that has two tips. The smaller tip is similar to a propane or Mapp gas flame. The large tip will give you the heat needed to hard solder your boiler. I use the Victor torch with propane...

Your design will work. I would have the cable angle steeper. Make the column higher so the cable is more than 45°. The column itself 8" square I assume is good for much more weight than you could get into a garage. I do not see a dimension for the lift arm, appears to be at least 6" high. Plenty...
