I suspect, once you clean the threads a bit, and the surface where the nut meets the frame, it may thread easy enough to reduce twisting. On my coping saws, I need to hold the handle to prevent twisting as the tension goes up.Here are a couple pictures of the area in question. I’m not sure that there is anything to stop the blade from twisting when tightening. I guess you twist the blade straight after it’s adequately tensioned then tighten the knurled nut against the frame to keep it straight.

I tried a straight grip dovetail saw, could not stand the ergonomics. I realized for me to make it work, I needed the work around hip height, else I could not saw straight.he always used a straight grip hacksaw, like yours Timm. Said that no matter how you angled the blade or the angle of cut you took, the grip was always the same.






In its own thread would be my ¢¢, keep the story together and reading well. Looks like quite a challenge.Anybody interested in progress pictures?
Still waiting for some tools to finish these breast drills. So, in the meantime, I am working on a M-F 97. I agree with others that this is a beast. Weights about eight pounds. Here are before and after pictures. The after represents cleaned and polished, but not yet nickel plated.Started working on a interesting Millers Fall No. 99 Breast Drill. First thing that caught my eye was the bronze gear. Figured someone dropped it and a patternmaker cast a bronze copy. However, as I've started working on it, I found a lot of other problems. This drill has seen a lot of abuse and incorrect repairs. Trying to fix it is a challenge. First, the gear, while it looks good and the teeth are well made, the hole for the main pivot is oversized letting the gear wobble. I will ream it out a little and stick in some bushings. Next I noticed a large gap down next to the chuck revealing the bearings. They were very exposed. Left this for later. So then figuring out the gear change selector and how to remove it. (A pin going through the middle). Removed the pin (it was bent), and then the gears came out. Took the gear section apart so I could see how it works. Clever. The gear section everything looked ok. The shaft that goes through it though is another matter. Speculating, but it looks like someone had removed this and lost all the bearings. So they used what was on hand, which were larger. These larger bearings moved the shaft further out of the gear section, so they drilled a new hole. I have new bearings on order. The bearing raceway was also loose and will probably do something to tighten it up (JB Weld?) Started the process of cleaning and polishing the frame. Looking better, but still have a ways to go. Will post pictures after nickel plating done. Anybody interested in progress pictures?

Here are updated pictures. Nickel plated and painted. Walnut handles. Almost done. Have a few little details to take care of.


Close, an EconomyMy quick look notes this as a Langdon. It's in decent shape. No saw and no need so I'll put it in the classifieds.
Do you mind if DATAMP uses your photos to update the lists for those patents?Millers Falls/Langdon Acme mitre box. I have the patent # for 8-6-1895 (544092). Looking for the patent #s for 10-23-1906 & 9-28-1909. This is for sale in the classifieds. +/- 100 yrs. old.
Thank you. I do the plating myself. Basically, the tool needs to be cleaned up, smoothed out, polished, plated, and then polished again. The parts are typically plated individually, but smaller parts are grouped together. The plating takes about an hour. It's everything else that takes a lot of time. The honest truth is that I am not likely to get paid for all the labor involved. I do it for the joy of preserving tools. I do not buy the collector quality tools, instead look for rusty or damaged to fix. For instance I am working on four Yankee 1555 breast drills and need to replace all eight of the wood handles.What a fantastic restoration! Regarding the nickel plating, what kind of preparation is needed and was it difficult to locate someone who does this?
No. That would be fineDo you mind if DATAMP uses your photos to update the lists for those patents?
I have one too. Like you, I really like it. Found an auxiliary fence that might interest you.My Millers falls skew block plane I use for the boats we build. It’s great little plane and being it’s skew will not tear out as much with figured Mahogany
More specifically babbitt bearing scrapers. For those that don't know, they used to cast bearings in place around the shafts. They would then use these types of tools to clean up the outer housings. When the bearings get worn, they then remove the babbitt and melt it down to pour new bearings. Very good recycling. Mostly lost skill today.Babbitt scrapers?
