I know have the cross-slide working, the key was having at least one shoulder on the extension. I was using John's site (Gadget-Builder) as a reference site and used as recommended a 608-2RS bearding. As the inner race of this bearing is I believe 8mm in diameter like the lead screw, no...

I am hoping that someone might be able to shed some light on what I am doing wrong with a cross slide extension to my C2 (7" x12") mini lathe. Let me start off as to what I have completed and or purchased for this modification. 1. I have purchased a 608-2RS bearing for the modification. 2. I...

Hello All; I stumbled upon a possible error that had my tram not correct when in fact it was! When tramming my milling machine I was using the top of my machinist vice, it had not occurred to me that the top of the vice might not be level as it is a ground surface, Wrong! The vice is .18mm...

Hello Bogs; Boy am I bad I responded with out fully reading your post, sorry about that! Thank you for helping me with the vice issue. Regards Al

Hello Bogs; I am sorry that I failed to mention the type of machine I am using, the machine is a ZAY 7045FG/1 milling machine. If you look at the picture to the right of this post and beside my login name; Ageless, you will see the machine. The picture does not show the steel stand for the...

Hello Bogs, thank you for the reply! I was hoping to get more information as to why I am not able to get the Moire' pattern when the mill is trammed properly. In my description I mentioned that I re-trammed the mill then did another surface cut, went back a second time and checked the tram and...

I have been having problems getting a decent finish using a face mill making .05mm finishing cuts. I was advise to remove the carbide cutters that came with the mill and use HSS instead. This I did however the result was only marginally better. I was advised to look for a Moiré pattern...

Hello Greg; Could you elaborate on what the "soft -O" means? I am new to metal working and just learning, so information helps greatly! Thank you

Hello All; I was in need of some 12mm (1/2”) aluminum plate for a project and tried to source 6061 aluminum but my supplier could on get 5083 aluminum. My question is how do they compare to each other regarding their machinability? Have others been able to work with both types of aluminum? I...

Hello All; Thank you for all of the posts, great information here. I have decided to go with the "Harold Hall" design for the boring head. I have completed the body and it went very well, the cutting of the dovetails using a 6mm end mill was surprisingly easy. Will now start on the carrier...

I just finished cutting some dovetails with end mill and it worked out real well. However I am interested in adding into my tooling a dovetail cutter for future projects. What size of dovetail cutter would you recommend as the best to buy? In addition I have seen cutters with 45 degree angles...

I want to build a boring head for my Milling machine, the milling machine uses a R8 Taper and I was thinking of using 1/2" or 5/8" boring bars. Does any one have a good plan for building a boring head that is not to complicated? Thanks in advance. ;D

This might seem like a dumb question and it probably is but I do not know how to gauge whether a carbide insert used in a milling machine needs replacing. I understand that if the insert is chipped it needs to be replaced, I understand how to evaluate HSS end mills for sharpness. Is the answer...

Hello All; The questions keep coming! I have been making up several sets of parallels on my milling machine and have been hogging material for many hours. I have been using a 1 ¼” carbide insert cutter to do the roughing to size. My question has to with feed rate on the X-axes. The speed that...

What I was referring to was in fact a Wankel type rotary engine. Strange that some one else would have a site with the same user name I use here. I have always be amazed with the simplicity of the Wankel rotary type of engine and had thought many years ago that I would catch on however...

I have always had an interest in a gasoline powered rotary engine, has anyone every tried to build one? My interest is in building a scaled down version which actually runs. Are there plans available or kits? Thanks in advance. ;D

Hello All; Hummm under the vice, that is the only place I did not look as the vice has been mounted for over a month and one half. Thank you all for the information, when I remove the vice I will set them up. Best Regards

I purchased the same one several months ago and it works great! The name on the indicator is in fact "Mitutoyo", and says that it is made in Japan. Of course having a name on something does not mean that it is the real thing, I live in SE Asia and see that every day! However my Test Indicator...

Looks like the attachment did work!

Hello All; I received these two rectangular pieces with my 5" milling vice, there was also two small screws that came with it. I have looked at the vice trying to find where they might fit but have not found any small bolt holes. I at first thought they where stop blocks but can not find...
