Re: Mantle Build Question
开云体育Hafele makes a lag that has two adjustable eccentric collars on it. You install them into the wall studs, drill holes 13mm or 17/32” in diameter about 5” deep into the shelf and then adjust the collars to make the shelf perpendicular to the way and slide the shelf on. No visible means of support and they work well. Not sure if I’d use them for a solid 7” thick mantel unless I could get two or more vertically on each stud, but they work great for shelving.

开云体育One nice things about a french cleat is that the thing hanging on the cleat can be leveled by placing shims between the halves of the cleat. ?We hang a lot of art work with french cleats. ?Also, most of the shelves and things on the walls in my recently liquidated shop hung on French cleats.

Hardwood glue-up panel on top on cabinet - wood movement
Looking for advices,
I am building floating (not touching the floor) lower closet cabinets and plan to put a hardwood panel glue-up on top. The assembly will be located in a recessed area and bumped into drywall on tree sides. So, no space for expansion on the sides, space for extension in front only. I am wondering if I need to use something like you can see on this web page to fix the glue-up panel to the top of the lower cabinet? Or I can be good with large holes (like Domino type holes) in the cabinet top and screw with washer to allow for movement. Thanks, Bill |

开云体育David,The easy glide is a step up. ?My Profile shaper had easy glide but the spindle position was controlled by motors so I don’t have a direct comparison of hand wheel to hand wheel from old trunnion to easy glide. I miss having a sliding table saw and a nice shaper. ?The two machines in the sale would make a very capable shop just add in Macs camps, Nordfab ductwork and an RL200 and off we go! Joe

Re: Mantle Build Question
开云体育David, That makes perfect sense. There is brick, on the wall, where this is going. I know the guy whose house it is going in but I am primarily helping my neighbor who decided to take up this challenge.?Brick does add some mounting challenges that i will need to figure out. After all the suggestions, I have to say that I would not have considered french cleat (thanks Joe). I have a hutch hanging with french cleat in my shop and I am certain it weighs twice, if not more, than the mantle. The simplicity of a mounting block is still attractive. I do not see why it would sag. The mounting block should not move once secured to the wall. The pocket done (in the rear of the mantle) on shaper should be precise and with .005” capability on the planer i can make the mounting block fit like a glove. I think a hardwood mounting block will hold screws better and reduce chances of sagging. Imran On Jan 6, 2021, at 5:09 PM, david@... via groups.io <david@...> wrote:

Re: KF700sp and AD741 used pricing
开云体育Mike, You made the right call in my opinion. The price being demanded is for a pristine machine with everything in excellent working order. Having said that, I have 2002 KF700 and no issues with trunion. So I personally would not walk away based upon that but if I cannot check the machine then the price has to reflect that. I completely understand that double trunion is preferred. I would not buy a used machine of this size and price if I could not test it, put a precision edge on it and check the arbor runout.

When looking at any machine that hangs the guts from the cast iron table, you want to put a straight edge across near the opening to look for any depression in the top.? Beefing up the casting is cheaper than beefing up the base so many machines now use the
table to support mechanicals.? That is also aided by the smaller frame lighter weight motors and lighter components.? Some lower end machines also cheat on the table so the design isn't always better than using the base as the anchor.? Straight edges, feeler
gauges, dial indicators, and a good level ( like Brian's ) are your friends.? Don't leave home without them.? Dave

Re: KF700sp and AD741 used pricing
开云体育Brian,I know that but I was wondering what Mike thought. I ran 40 pound cutters on the year 2000 F700z I had with single trunnion and it worked. ?Hansjorg Felder told me the single trunnion was strong enough when I toured the Felder factory. ? That said I would not recommend running 40 pound cutters for production but a hobby user running 6 or even 8” cutters on a single trunnion will be fine. I think price is the limiting factor for this lot but I would not worry about the trunnions.? Joe

Re: Mantle Build Question
I've done similar shelf installation down and dirty with lag screws into the studs. Once driven, the heads were cut off, and holes bore in the back of the shelves with an auger bit. Squirt some PL adhesive in the holes and slide it on.

Re: Mantle Build Question
开云体育David, Thanks for the details. I guess if I were to do this, i will probably epoxy the brackets in the mantle and then bolt the verticals to the studs while keeping mantle level. This on account of my ability to free hand drill as required to do this right. Imran On Jan 6, 2021, at 1:22 PM, david@... via groups.io <david@...> wrote:

Re: KF700sp and AD741 used pricing
开云体育The older machines have a single trunnion affair and it supports the whole spindle and motor system on one end of the assembly. This brings into account an adjustment nightmare dealing with “angle of the dangle” as well as toe-in and toe-out in the other direction. Failure to get the angle correct creates all sorts of issues when tilting the saw/shaper aggregate.All that said, my old machine is of this design and once set, it’s pretty stable. If I was looking for a machine though, it would be the double trunnion machine… more easily adjusted and has better longevity of settings, and with the polymer materials used in the trunnion the smoothness and easiness of tilting is considerably better.

Re: Kappa 400 Below Table Dust Extraction + Kappa 400 Review
Mark,
Can you give us more colors about your reasoning of virtually going T60 instead of K940, or even T60 instead of Kappa 400 (basic no X motion). Price wise, as far as I know, a T60 with DRO is more comparable to a Kappa 400 basic. Thanks, Bill |
