Rob According to G-Wizard the Major Diameter for a m4x.7 thread is 3.838 to 3.978 with a mean of 3.908 so if you are turning you part to 4mm then your major is to big and the threading die is having to take off the extra. You can get G-Wizard at http://www.cnccookbook.com/CCGWizard.html It...

Jerry I've been an Alibre user from there launch. Running 2011 also. Don't you just love that you can build your engine on the computer screen, grab ahold of the crank shaft and see if every thing works the way you want it to. Work in progress drawings would be interesting to see also. I...

Jerry Your vertical twin is looking very nice. Am I correct that you are using Alibre 3D cad to do your design work. Would you care to share your drawings so other folks could also build this engine. Dave You may want to take a look at this web site the make a very nice lost wax cylinder...

Dude With the tools you have at present it is going to be a bit hard to build an engine. Ideally you would like to have a metal lathe (does not have to be big) a milling machine and a drill press. One way to do it with limited tools is find one of the engines that is offered as a pre machined...

Brian I've been watching your conversion of the 2D drawings to 3D. I had downloaded the drawings myself and was playing with 3D to better understand them. In drawing the Cylinder Body I believe that we are looking at a wet sleeve engine vers dry sleeve. find enclosed my drawing of the Cyl Body...

That is one big bird. We are flying into Manchester next Saturday but on a much smaller bird I expect. Dave

Pat Did a few changes to the Cylinder as well Dave

Pat I downloaded steam chest, base plate, cyl head, and cyl. The one thing that I see common to all the parts is that you have your units set to 4 decimal places 5 would be better. You also have your spinner set to .1" .03125" would be better. Cyl head is not a closed sketch. you need to...

Pat You of course know that there are three parts to Alibre. Parts, assemblies, and drawings. You also know that you start by making parts. Fly wheel, crank, cylinders. connecting rods etc. From parts you can tell Alibre to build you a 2D drawing. You then choose the views you want. Front, top...

I have a Boxford 8 inch made in England. What I like about it is it has power on the table for left and right or up and down. I can use power feed across the top of the part and then power down the end of the part without moving the part. Also the table will rotate left or right up to 90 deg...

Howdy Dan long time no talk to I have been playing with a attachment for my shaper to cut spur gears using the same method that you are using. Plan on using music wire just as tight as it will stand. PD templet will be on the ram side of the table as you have done but will put indexing at the...

Lathe Nut I have about 1000$ invested in Alibre. I like it very much. You can draw various parts and assemble them and check for interference. Will you be working from sketches or will you be measuring and doing drawings from those measurment. I believe you can still download a free copy of...

Hi all My shop started out as a 7'X18' trailer. Added 12'X12' to back of that, year later added another 12'X12' to the end of that. Next year adding 24'X10' on the side of the 12X24. That will be the end of it cause the wife is getting upset that the shop is getting bigger than the 8'X26'...

Dusty I believe you are fine asking your questions here. Jigs are jigs be they for building engines or other things. For the 5/8 counter bore. Go to Enco and look up piloted counter bores. You drill your hole for the bolt to a standard clearence diameter. then run a piloted counter bore in to...
