Jim Casting is a real learning curve and if you do it for 50 years you will still have thing to learn. When I read your messages on your sand, it might not be your sand. The pattern can hold a lot of answers and one thing I have learned is the smoother the pattern is, it will much easier to pull...

The owner is a jurk and will ban you in a heart beat.

The real reason is if you joined Machinist Gazette you have been banned. Nelson does not play that!

Would using a swing up threading tool - http://mikesworkshop.weebly.com/swing-up-tool-holder.html - and leaving the half nut engaged make it easier ? Mike Yes a swing up would help but that does not stop the carriage from moving. My problem is when the handle hit the stop it causes my...

Brian Mufflers have more good reasons other than noise, they produce a back pressure that can make a engine run better. Thanks for all you do. Sockets I like that stand up pipe with the flapper on top. Very nice and a good looking engine. Nelson

John It is so good to hear the positive attitude. One day at a time regardless what the docs have to say. There is a greater power and he is saying "no yet". Build yourself up and we will be looking for the next adventure you decide to take us on. Happy machining. Nelson

I read that article from WILDHABER-NOVIKOV GEARS APPLICABLE. It make a lot of sense in his theory but I wonder why his was not kept because of load and stress. Somethings we just do not understand. Nelson

Anatol I do not see any reason you could not take and use a wider tool and grinding the round profile into it and when pushing it through the hole cut the sides of two teeth at a time rotating 6 or 8 times to produce the coupler you need. Keep us up on the progress. Nelson

Brian I want to make a larger carb and looking at yours I would like to scale it up from your design. May I have the the file on it. Thank you Nelson

looking at the splines, I've never seen on as such but could it be a badly worn spline shaft? The spine shafts are made that way for ease of disconnect. Farm machinery use it as a prime universal way to drive all their equipment, except for the modern hydraulic drives. I believe a straight...

Tomlinson Thanks for sharing and that was a beautiful photo album of the build. Very nice job, feel proud Nelson

Rlukens, I do not see no other badges under your name other than: "Well-Known Member" and "POTM Winner" Sorry Nelson

For everyone in the USA crying about cost just wait and see what Canada's 45% does to it. You will go back to wood. Nelson

Looking at the old post and hit this one and had to update. I have a Millrite Mill and all the locks I have extended the handles so it does not take very much pressure to loosen them. On my South Bend 10K I have not come up with anything to assist when threading. Engaging the half nut more than...

Well, get ready for the price to double. Canada just put a 45% tariff on steel. Too much going on at the top that is going bankrupt this country.

Stuart That is one of the best videos on why not to use cheap containers like cans. When I started in the 90's I could get about 3 burns out of a can but the metal and the thickness is not what it was then. If you choose a metal can this is exactly what will happen. Very well done. Nelson

Richard I would love to see some pictures, it seem like you have a very special box tool? Nelson

Edi Very nice engineering solution on your stands. Very nice build, very impressive. Nelson

The rotary broach seems to be the best so far, broach turn down the press fit and part off. Nelson

Neil As small as they are what about a form tool to do both the cylindrical part and the head-part off, all at the same time? Pop them out like popcorn!!! Nelson
