All else being equal, simpler is generally better, although the argument for facilitating heat treating seems reasonable. I expect that a good percentage of the attachments would get some type of heat treatment.

You still have to loosen it the same amount to get past the metal behind the hole. Maybe it could be loosened for a shorter time, but how does that help anything?

The tang I made that fit OK was a rectangular for the full length of the tang like in the first blade below. That would have more support and could probably be held just as well for any processing. And it would be simpler to make, which still leaves me wondering why the complicated shape is used.

Reciprocating saws have attachments with a complex tang shape as shown below I had to disassemble a Milwaukee sawzall blade holder recently, and I noticed that it appeared a simple rectangular shape behind the hole would fit. I tried making a plain rectangular tang, and it fit without any...

I am scraping a concrete foundation to remove peeling paint and joint compound that was put under the paint. Scraper blade attachments for a reciprocating saw (e.g., https://www.amazon.com/Reciprocating-Scraper-Multifunctional-Carbon-Cleaning/dp/B0B1HC5B3Q?tag=atomicindus08-20) are making the...

I am surprised the larger puller is not even stronger given the size difference of the drums. The OTC puller is rated at 7 tons, while the bigger one looks like it is using 3/8 inch grade 70 chain, so just about 10 tons for the three pieces. However, sometimes it is hard to judge things from...

I had not been overly specific because I am looking for a general tool that would work in a variety of applications, much like a gear puller does. The issue with pullers is that they do not allow you to get around a big obstacle like a tire or the side of a frame. Like gear pullers that come in...

Both wheels have been removed already. I have seen people swear by letting penetrating oil work a long time. I was not in a hurry at all, so I kept adding penetrating oil every day or few days and trying to break the frozen parts loose for several weeks as an experiment to see if the parts would...

The pictures of valve spring compressors are essentially what it should look like with possibly some variation on the fixed end to allow more flexibility. I had been assuming that there is a tool like I am describing, but I just did not know what it was called, so I could not find it. The hope...

That is the basic idea, and I had thought of that . However as mentioned already, there is definitely a strength issue with an ordinary spring compressor. Valve springs exert on the order of hundreds of pounds of force, where tons would be the right order of magnitude for the tool.

I have not done it, but I have seen it done. It can be a solution sometimes, but there are cases where that would not be a great solution. Here is an example of that from the same snow blower with the frozen wheels. The frame has a jackshaft with a bearing on each end of the shaft outside of the...

That would work OK if there is something behind the wedge that is strong enough and close enough for it to press against. You could deal with gaps using shims, but you still need something solid to wedge against. I would like a tool that presses against the shaft since that is always there.

For the specific case of a tire on a snow blower, that would work, except that the tires are often directly put on the shafts with a pin through the shaft to keep them from coming off before they had a chance to rust on.

One use was a snow blower tire that did finally come off after a great amount of penetrating oil and weeks of patience. However, I have come across similar things and assumed that there is something already made for the situation.

That is the right idea, but the separator plate would need to be huge.

Hi All, I am looking for a tool that I assume exists but that I cannot find because I am not sure what it is called. It would essentially be a portable press that would allow something to be pressed off of a shaft when there is only little space on one side of the thing being pressed off...

Thanks for the suggestion. I looked at their site and found that SDS-max bits are a lot cheaper than the 1-1/4 X 6 hex equivalents. I do like to have adapters to be prepared for unexpected circumstances, but it seems like getting some duplicates may be the best solution here.

I already have the air and hammer. My point is that just dragging the air hose is more work than a small job. Adapters are rarely the ideal solution, but they can be the lesser of evils.

Because I have the 1-1/4 X 6 tooling already but would like to have an easier way to use it when the demands are light.

Hi All, Would someone point me to an adapter that would accept a 1-1/4" X 6" or 1-1/8" X 6" hex tool and fit inside of an SDS-Max chuck if there is such a thing? Sometimes it would be nice to avoid dragging out a jackhammer and air hose when the work is relatively light. Thanks for any information.
