that's a man sized project! The scraping of the mini mill x/y you see above is covered in great detail in a series currently appearing in the Home Shop Machinist on scraping. It started with March/April '11 issue and will run for quite a while (no doubt to the delight of some and chagrin of others....its long but its what it took to cover it). Its fairly exhuastive, from basic equipment, techniques, making a scraper, making a rotary lap to keep it sharp and a hose of projects

I thought scraping the mini mill would be an excellent inclusion as its gives a bite sized example of scraping dovetails and also since there are so many out there, it gives everyone the resources to get them running like Swiss watches. This thread was partially a catalyst for that particular project. For the guys who realize there's no free lunch, either pay big bucks or roll up the sleeves, it hopefully brings understanding to how bearing surfaces are aligned and shows the way to fixing them properly.

thanks for the encouragement & interest!

I just seen the Turcite B somewhere in strips with different thicknesses and lenths ( they also had the glue). I cant rememeber where it was but if I find it I will post back. I think doing the search like someone already meantioned with google will find it for you. It is available if you look. ALso I think they call it Moglice or something like that is also out there.


JUst a thought, when glueing on metal of any kind using something like paint thinner to clean the surface real good should be done on used parts. Lacor thinner I think works best. Oils, grease will inbed in metal and it takes some work to get it out. SOmething as simple as Dawn dishwashing soap can help to get it clean first. Even something like a finger print on the metal can cause problems so use the thinnner last and use it right before doing the job.

Sweet! Thanks!

Am I correct to think that in order to true up a 54" mill table, I would require at least a 54" straight edge?

I have found raw castings on machinerepair.com. I have yet to find any other provider of raw castings, especially in the length I require.

I have done a little pattern-making, and live near an excellent foundry. If it comes down to it, I will make my own pattern, and maybe sell a few cast iron blanks on ebay. I have never made anything on that shape before, but I can talk to the resident pattern-maker there to nail down the risers/auxiliary stuff required to get a good casting.

Either way, looks like I will be needing a larger surface plate than I thought.
