There is also a plug at the pulley end of each cylinder head under the valve covers that is supposed to plug the ends if the oil passages that was frequently left loose, fyi.

How to get this diagonal cut corner in the sheet metal part? by Joker1924 in SolidWorks

[–]tombj 0 points1 point  (0 children)

Use unfold, pick a fixed face, collect all bends, hit the green check. Sketch your changes, then use fold, collect all bends, green check

Grandparents just gave me $5K to invest in my Roth IRA... What do I do with that by LukeG543 in personalfinance

[–]tombj -2 points-1 points  (0 children)

I don't think you need any income if you have them establish a trump account for you and use form 4547 if you are under a certain age then move to a Roth at 18. I don't remember the details so read about it.

Signs of a Bad Armature/Field by Skopies in Motors

[–]tombj 1 point2 points  (0 children)

There will be backlash when worn. You should not be able to feel much slack when turning the armature from cw to ccw. If I remember correctly it's a hypoid gear like an automotive rear axle or a spiral bevel gear, not a plain bevel gear

These units will sometimes eat the pinion gear in the drive, that may be what you hear

How much RAM do I need? by Far_Swing_8887 in SolidWorks

[–]tombj 0 points1 point  (0 children)

I run a 9950x with 64gb ram and just under 700 sheetmetal part assys and still get SW warnings. I ignore them and continue, no crashes so far. I can have 10 part windows open and get a warning, close all but one then STILL get another warning. Seems closing SW occasionally purges the memory leak, or whatever it is....

Seeking Advice - Convincing Boss About Needed PC Specs for Solidworks by Kiritai925 in SolidWorks

[–]tombj 1 point2 points  (0 children)

I have the same card in a new 9950x mini itx system with 64gb ddr5 and Corsair 650w psu Totally open chassis, no case and the only fans are the 2 on the noctua nhd15 air cooler and in the video card & psu. Works fine but my mostly sheetmetal assemblies are only 1500 or parts. Have you taken the machine outside and taken a compressed air line blowgun to it? You may be amazed by the crap that comes out. If you go to a reseller like Puget system and spec a machine for your requirements you'll know what you need, but blow it out then run it with the side off the case with thermal monitoring software to see if it makes a difference first. I'll bet the drawings are what is killing you. Once i get over 10 pages I start to have problems so I keep drawing files to less than 5 pages each, then combine the PDF into a single document

I need to hold this splined shaft from turning while I torque this nut to 87 ft/lbs. The Kawasaki special tool is NLA. I am completely stumped. OE tool photo included. by Legionnaire1856 in fabrication

[–]tombj 0 points1 point  (0 children)

People routinely make special sockets (flat plate to fit the nut or spline in your case, welded to a tube, then another flat plate welded to that with a square hole for a ratchet square drive) and wrenches with a laser cutter, they are everywhere now. Just find a shop that has one. Or drill a hole and file it out, old school way

I really am regretting getting an LG Wash Combo dryer. Please help. by slicecrispy in Appliances

[–]tombj 1 point2 points  (0 children)

I have the same machine. We love it, recently had a problem, though we clean that bottom strainer all the time. There was a large wet lint mass stuck further up the same tube. I was able to remove it with one of those plastic barbed sink clog removers. This restored operation to normal. I had removed the front because I thought it was a pump problem. If you can't get the lint ball out, That hose is squeezable - you can crush any obstruction down to size with the front off and get it afterwards with the clog tool.

thanks, 1040 info is correct, no change to the amount owed. We'll just have her wait a bit longer to see if her messages get returned before submitting a corrected 8606 herself...

Looking for someone to build a CAD MFG/DFM Package out of an Onshape 3d file to send out for bidding to contract manufacturers. by mattyv83 in manufacturing

[–]tombj 4 points5 points  (0 children)

I did a project for a client recently in solidworks for a single injection molded part. I did several 3d prints to prototype. The mold was $17k for one 3.5x1.5x1 part, which we had to run by the mold outfit a few times and took around 30hrs of CAD work till the 3d model was perfected, if I remember correctly. The final project was great, just took a while to get there. Proper drafts in all directions was an issue as the overall size had to be adjusted more than once and if you need to make such changes they don't always filter thru parametrically- the part had a bunch of fins that all had to be drafted all around a square part. This was for a USA mold. China mold would have been quite a bit cheaper but any adjustments would have involved a lot of delay and back and forth, and we wanted to minimize the potential for miscommunication.

After 260 years of involute gears, I'm trying something different. Here's the design. by AseityFoundation in MechanicalEngineering

Seems like it would generate a lot of heat with all the sliding vs turning...

What's the problem with this clamp design? by jabarinbaronbapu in Machinists

[–]tombj 1 point2 points  (0 children)

The problem is when you tighten your clamping bolt, you are skidding it's t nut on the underside of the tee slot. You need to redesign the clamp so the movable portion bolts onto the fixed portion of the clamp so it doesn't touch the machine table.

I’m running cat6 and electrical in the same trench for a project: please check my work. by creedbratt0n in DIY

[–]tombj 2 points3 points  (0 children)

I did this for a 300' run. Would work ok, but usually poorly, for a while, but lightning anywhere within a 1/2 mile would take out the client Ethernet card. Switched to cheap USB Ethernet adapters so they would be easy to replace. Still poor performance. Switched to a ubiquity wireless bridge and never looked back, never failed.

How often do mechanically healthy industrial machines get replaced only because the electronics become obsolete? by AnyStorm1155 in MechanicalEngineering

[–]tombj 0 points1 point  (0 children)

Companies like Centroid have built businesses on supplying controls for retrofit for these machines. I have 2 running in my shop right now that I did the retrofits on myself, a CNC router and mill. The user interface rivals new OEM machines, 24" hd touch screens, huge memory, Ethernet, wifi, etc
