Upcoming swap meets in northeast US

Anyone have any info on upcoming swap meets in the North East of US. I know it is late in the year but I was looking to go somewhere for a few days. Might as well make it worthwhile. Something on the order of a Cabin Fever expo. Thanks.

Re: Turning 1" axle between centers

Having an older lathe myself I found shafts cut to be smaller on one end. I blamed it on cross feed screw wear and backlash. It seemed that when cutting the tool was pulled into the cut. When I tightened the gib screws to the point of locking the cross slide problem solved. This may help in your cas...

Re: Atlas Lathe Model 3983 12 in

Cutting between centers using a lathe dog can be a major contributor to chatter. If that lathe dog can go back and forth in the slot chatter will happen. If your bull gear pin hole is that worn it will contribute to chatter. It should be a easy fix for you. (drill and bush) Since we can only guess w...

Re: New tooling on old lathe

Sure. I do it all the time. I get the brand X models made in china from CDCO. Dorian is out of my price range. Along with Aloris. I have had good luck using these. I get extra tool holders because they are inexpensive. The set screws are junk so I got a box of metric screws from Fastenal and fixed t...

Re: Help with SB large dial upgrades

Go to the practicalmachinist web site and search large dial upgrade. Everything you want to know. Also, if you are going to do it yourself watch youtube Mrpete222 or tubulcain (same guy). great video on making dials using a saw blade for indexing.

Re: Lathe tailstock alignment and drilling holes

You can be close to center but not center for many reasons. If you want true center after you center drill single point the hole with a tapered cutting tool set at 60 degrees. It will be true center, period. Many youtube videos on this subject.

Re: SB Heavy 10 Project, Carriage Stop and Tool Holders

You are going to be pleasently surprised how well and long lasting the aluminum one works. I have a few I made years ago from aluminum and they work just as well as a steel bought one. Although with CDCO offering new steel ones for $9.00 each why bother making them. I know its the challenge. Nice wo...

Re: Phase II spacer. How to change Mask Plates??

There should be a 24 tooth spacer plate that came with the indexer. You can use that for spaces of three. Count 8 spaces. The masking plates are for doing production stuff. For a one off just use the 24 space indexer. You have to remove the chuck (probably threaded) and you can place the masking pla...

Re: Anti-matter is real: conclusive proof

Up until a short time ago I truly believed in the anti-matter. black hole theory described here. I have machined a lot of little plastic parts both white and black. Having sorted them on the bench and organized them for future assembly only to return in the morning and find that many were missing. L...

Re: Boring a 9" hole in 3/8" thick cast iron

Don't put an electric arc to the cast iron. You will have to grind it to get a machinable surface. A local machine shop should be able to bore it for you. Sometimes you have to cry uncle and let some body else do it. My 2 cents.

Re: Turbulators

Turbulators are used in home and industrial steam coal fired where the flues go straight up from the fire box. EFM 520 older style comes to mind. Never saw a turbulator in a boiler that had the flues horizontal. One thing is certain, if those flues were removed the steaming ability of the boiler was...

Re: Need help on larger boiler Silver Solder project please

I have been welding/brazing/silver soldering larger parts for some time. I admit I never soldered a boiler. I have made ornamental bronze/copper/brass stuff that was a PITA to get hot enough for an acceptable joint. Yes heating with an additional torch can help but I only have two hands and the move...
