    Marklin 4158/91/7 - Oh boy is this cool

    Del Here is my current cleaning project for one of Gen’s sewing machines. It was made in about 1885. I am showing you four pictures of the base. I used the following to get from the before to the after. Soaked in dish soap and water for two days, just a few squirts in the water. Used a...

    Marklin 4158/91/7 - Oh boy is this cool

    I would recommend the following from your list: Do 1 and 2 first, clean as best you can. Do not pressure test boiler, these were designed to fail. They are for the most part soft soldered together. Most run at less than 30 pounds. Certainly fire it up slowly at some point. Keep pressure...

    Bob - good to see you are up and running. I have an Albrecht keyless that I purchased brand new, also purchased an Albrecht R8 adapter for it at the same time. Run out was worse than my Jacobs 14N it was supposed to replace, and worse than my Rohm. I put the Albrecht chuck on a no name R8...

    K As to your question about speed, my experience is down to a #80 drill ie about .3 mm. For any hole in the range of #70 or less I use about 100rpm or less watching the hole with loupe. I take real light cuts and you can see the bit cutting. The reason for the slow speed is I cannot control...
