How big of a hole do I need to drill for cam lock?
How big of a hole do I need to drill for cam lock?
Use the 3/16″ bit to drill holes for the posts to screw into. The depth isn’t terribly important as long as it’s deep enough for the post to screw in securely up to the shoulder of the thread. I found 7/16″ deep worked well. Before putting the posts into the hole, I transferred a mark to the other piece.
How big of a hole can you drill with a reamer?
Where drilling can obtain size tolerances on the order of plus or minus five thou, or a hundred microns, reaming can reliably hold tolerances inside of a thousandth, or 25 microns. As a rough rule of thumb, you should run a reamer at half the speed, and twice the feed-per-rev, of the drill you just used.
Do you notch or drill holes in wood?
When possible, notch a stud near the top, rather than the bottom. Don’t locate holes and notches near large or loose knots, and don’t group too many in the same area of the stud. Finally, notch only when necessary; holes weaken it less than notches.
What do you need to know about cam lock connectors?
If you’re not familiar with them, cam lock connectors are a two part fastener that looks like this. They’re used to connect two flat pieces together at a 90 degree angle. Things like the sides of book cases, or, in my case, a side support to a table top.
What should the runout be between camshaft bores?
In general terms, the maximum acceptable runout between individual camshaft bore locations is about 0.0005″. Bear in mind that in addition to machining the cam bores to accept the roller bearings, the cam tunnel run may require clearancing to allow pass-through of the bearings during installation.
Do you need to block oil feed holes on cam bearings?
When installing roller type cam bearings, there is usually no need to block or restrict oil feed holes to the cam bearings. Roller type cam bearings usually require only splash lubrication. However, oil feed holes can be blocked off to reduce oil aeration and windage losses, depending on the application.
Why do cam bores need to be aligned?
Just as a block’s main bores can become out of round or misaligned (creating the need for align-boring or align-honing), the cam bores can be subjected to similar geometry changes. This is why camshaft fitment problems sometimes occur when dealing with a used block.
What should I do before installing cam bearings?
According to McBroom, you’ll want to have the proper installation tools and keep the alignment close when you drive the cam bearings in. Make sure the oil holes are lined up. Also, you’ll need to prep the block to make sure there are no sharp edges, and if so, chamfer them prior to installing the bearings.
